Better Parks for People Who Need Them: The Proposed “Anti-Equity” Metrics

Proposition B provides San Francisco Recreation and Parks Department (SFRPD) with set-aside funds for the next 30 years. It also requires them to ensure equity for the parks, by spending more on parks in under-served areas. Let’s call those the “Equity” tracts (they’re based on census tracts showing below-average income).

Now SFRPD proposes a calculation method (“metric”) that indicates it’s actually devoting more resources to those parks already. (You can see that calculation HERE: item-2-equity-metrics-staff-report-final-080416) How? By simply assuming that only the “Equity” tracts use the parks within a quarter-mile of their homes, so that they get ALL the resources spent on those parks. Of course, that’s simply not true. The Equity tract users use those parks, but so does everyone else who lives nearby. (Large parks may even attract people from across the city.) They share the resources, they don’t get all the resources.

Tom Borden shows graphically what’s wrong with SFRPD’s current Equity Metric. In the next article, he will provide a more detailed analysis of this hastily-designed measure.


by Tom Borden

RPD’s Equity metrics show paradoxically that the disadvantaged neighborhoods of San Francisco enjoy more park resources than the average city resident, much more. On a per capita basis, the equity population is way ahead of the average resident. Below, the first number shows the resources for the “Equity” tracts (i.e., under-served populations, determined by census tracts), vs. City-wide resources.

  • Acres of park/1,000 people:  4.42 vs 4.00
  • Number of parks/1,000 people 0.49 vs 0.26
  • Capital Investment/1,000 people $64,003 vs $24,333
  • Recreational Resources/1,000 people 530 hours vs 284 hours

Do you believe it? They must be doing something wrong in their calculations. Let’s take a look.

The graphic below shows a 10 acre park where five census tracts are within 1/4 mile of the park.
Two of the tracts are equity tracts. For simplicity, let’s say 4 people live in each tract.

When SFRPD calculates their metrics, they assign 100% of a park’s resources to equity zones if an equity zone is within 1/4 mile of the park. For our park above, let’s use the SFRPD method to calculate the acres of park per capita for the equity tracts. Here’s what that looks like:park-equity-graphic-2

Using the SFRPD method, the 8 equity neighbors share 10 acres, or 1.25 acres per capita. Do they really have all that space to themselves? No. All those other neighbors standing outside use the park too. They put wear and tear on the park, occupy the tennis courts and picnic tables, take spots in programmed activities, fill up the trash cans, and take lanes at the pool.

The SFRPD method shows the equity neighbors are getting much more than they actually are. The right way to calculate this is shown below.


All twenty neighbors share the park, so each enjoys 10 acres / 20 people = 0.5 acre per capita. This is the same for equity and non-equity neighbors. The two equity tracts should be allocated acreage as follows:
8 people X 0.5 acre per person = 4 acres

The portion of any particular park resource to allocate to the adjoining equity tracts is based on the simple ratio of equity park users to total park users, in this case 8 / 20 = 40%.

If there 30 picnic tables, the equity tracts would be allocated 30 x 0.4 = 12 tables
If $1,000,000 of capital was spent in the park, $400,000 would be allocated to the equity tracts.

SFRPD needs to correct their accounting for parks shared by equity and non-equity tracts. The resources of each shared park should be calculated as illustrated above. If this is not done, the error makes it look like the equity tracts are being better served than they really are. Instead of having Equity Metrics we have Anti-Equity Metrics.

Another Attack on Trees in The East Bay

This article is republished with permission from “Death of a Million Trees“, a website dedicated to fighting unnecessary tree destruction in the San Francisco Bay Area. If you want to help save these trees, please sign the petition.

sign for East Bay MUD TreesAlso, if you would like to comment, EBMUD is accepting comments until September 16 2, 2016. [Edited to Add: The comment period has been extended to Sept 16.] This massive destruction of trees across our Bay Area affects us all. Trees fight climate change by sequestering carbon, provide habitat for native birds and animals, as well as for forage for bees and other insects, and provide shade and beauty. This is not just an East Bay issue.


East Bay Municipal Utilities District (EBMUD) is the public utility that supplies our water in the East Bay. To accomplish that task, EBMUD manages thousands of acres of watershed land. Like most open space in the Bay Area, the vegetation on EBMUD’s land is a mix of native and non-native species.

EBMUD is revising its Master Plan. The draft Master Plan makes a new commitment to destroying all eucalyptus and Monterey pines in favor of native vegetation. The draft Master Plan is available HERE. EBMUD is accepting written public comments on the draft Master Plan until September 2nd. [NOTE: DEADLINE EXTENDED TO SEPT 16, 2016]

Comments should be sent to or by mail to Doug Wallace, EBMUD, 375 11th St, Oakland, CA 94607.

EBMUD held a public meeting about its draft Master Plan on Monday, August 15, 2016. That meeting was attended by over 200 people. Most of the crowd seemed to be there to defend their access to EBMUD trails by bicycles.

There were 10 speakers who defended our trees against pointless destruction and the consequent pesticide use to prevent their resprouting. As usual, the Sierra Club came to object to increased access for bicycles and to demand the eradication of our trees. As usual, claims of extreme flammability of non-native trees was their stated reason for demanding the destruction of the trees. Update: HERE is a video of speakers at the EBMUD meeting for and against tree destruction and pesticide use.

If you are watching the news, you know that there are now eight wildfires raging in California. All of these wildfires are occurring in native vegetation. The claim that non-native trees are more flammable than native trees and vegetation is nativist propaganda.

Furthermore, our native trees are dying of drought and disease. This article in the East Bay Times informs us that 70 million native trees have died in the past four drought years and that the millions of dead trees have substantially increased fire hazards. In other words, it is profoundly stupid to destroy healthy, living trees at a time when our native trees are dying and pose a greater fire hazard.

We are grateful to Save the East Bay Hills for permitting us to publish their excellent letter to EBMUD about their misguided plans to destroy our urban forest. We hope that their letter will inspire others to write their own letters to EBMUD by September 2, 2016. Save the East Bay Hills is a reliable source of information about our issue. Thank you, Save the East Bay Hills for all you do to defend our urban forest against pointless destruction.

Update: Save the East Bay Hills has also created a petition to EBMUD that we hope you will sign and share with others. The petition is available HERE.

Douglas I. Wallace
Environmental Affairs Officer
Master Plan Update Project Manager
East Bay Municipal Utility District
375 11th Street
Oakland, CA 94607

Dear Mr. Wallace,

This letter serves as our response to the East Bay Municipal Utility District’s invitation for the public to review and comment on the draft of the East Bay Watershed Master Plan (“Draft Master Plan”) update. There is much in the plan to recommend itself and much that leaves a lot to be desired.

We are grateful that the Draft Master Plan recognizes the value of trees regardless of their historical antecedents, specifically noting that,

“Eucalyptus trees provide a source of nectar and pollen that attracts insects, which in turn serve as a prey base for birds and other animals. Hummingbirds and many migratory bird species feed extensively on the nectar. In addition, eucalyptus trees produce an abundant seed crop. These tall trees are used as roosting sites for birds. Bald eagles have roosted in eucalyptus groves in the San Pablo Reservoir watershed, and a great blue heron rookery exists in the eucalyptus trees at Watershed
Headquarters in Orinda. A great blue heron and great egret rookery was active near the northern arm of Chabot Reservoir in the recent past.”

The Draft Master Plan recognizes, “the ecological value and likely permanence of certain nonnative species and habitats,” including Eucalyptus and Monterey Pine. It recognizes that these two species of trees, especially Monterey Pine “provide stability to watershed soils” and “provide erosion control with a widespreading root system.”

It recognizes that they provide “protection from solar exposure, wind, and noise.”

It recognizes that they “provide biodiversity value (bald eagle and other raptor species) on District watershed lands.” For example, “Monterey Pine seeds provide food for small rodents, mammals and birds…”

It cites to the EBMUD Fire Management Plan which recognizes the value of trees in mitigating fire: “They do not represent a significant fire hazard when the understory is maintained for low fire intensities… Stands that are well spaced with light understory, proper horticultural practices, and maintenance of trees, e.g. spacing and above-ground clearance, can serve to minimize fire hazard.”

It admits that removing the trees would lead to inevitable grasses and shrubs which increase the risk of fire: “The most susceptible fuels are the light fuels (grasses, small weeds, or shrubs)…”

Finally, it recognizes that these tall trees occupy a very small portion of District lands: 1% for Eucalyptus and 2% for Monterey Pines.

Given their immense beauty, the habitat they provide, their mitigation against fire, the erosion control, all the other recognized benefits, and the fact that they occupy such a small percentage of overall District lands, why does the Draft Master Plan propose that they be eradicated over time?

The answer appears to be nothing more than perceived public will:

“As this species is considered a nonnative pyrophyte, regional pressure is present to reduce the number of Monterey Pine stands.”

“As a nonnative pyrophyte, eucalyptus plantations are a target of regional public pressure for removal.”

This is a misreading of the public will. The Draft Master Plan is elevating the nativist agenda of a loud, vocal minority over good sense, good science, ecological benefit, protection against fire, and the desires of the vast majority of residents and users of District lands. How do we know?

The City of Oakland, the University of California, and the East Bay Regional Park District have also proposed eradicating Monterey Pine and Eucalyptus trees and of the 13,000 comments received by FEMA during the public comment period following its draft plan, roughly 90% were in opposition by FEMA’s own admission. Moreover, over 65,000 people have petitioned the City of Oakland to abandon its effort to remove the trees.

That EBMUD does not hear from people who find beauty, shade, and benefit in the trees is not because they do not care; rather, it is because most members of the public do not understand the extent to which these trees are under siege by nativists, nor the level of cooperation these individuals are receiving from public lands managers to see their vision prevail.

For most members of the public, it simply strains credulity that those tasked with overseeing our public lands would cooperate with efforts to destroy not only large numbers of perfectly healthy trees, but given their height and beauty, trees that are the most responsible for the iconic character of East Bay public lands and the appeal of our most beloved hiking trails. And for what end? To treat our public lands as the personal, native plant gardens of those who subscribe to such narrow views. In short, there is no widespread desire to get rid of these trees and they should not be removed.

Indeed, the Draft Master Plan recognizes several “emerging challenges” as a result of climate change including, but not limited to, “increasing average temperatures, prolonged droughts, erosion, decreased soil moisture, and augmented risk of fires.” Tall trees like Eucalyptus and Monterey Pine help mitigate these challenges. For example, fog drip falling from Monterey Pines in the East Bay has been measured at over 10 inches per year. In San Francisco, fog drip in the Eucalyptus forest was measured at over 16 inches per year.

Moreover, Eucalyptus trees are an important nesting site for hawks, owls and other birds and are one of the few sources of nectar for Northern California bees in the winter. Over 100 species of birds use Eucalyptus trees as habitat, Monarch butterflies depend on Eucalyptus during the winter, and Eucalyptus trees increase biodiversity. A 1990 survey in Tilden Park found 38 different species beneath the main canopy of Eucalyptus forests, compared to only 18 in Oak woodlands. They also prevent soil erosion in the hills, trap particulate pollution all year around, and sequester carbon.

Many of these benefits are especially important in light of Sudden Oak Death which the Draft Master Plan admits is an ongoing challenge and is likely to increase because of climate change. If Sudden Oak Death impacts oak woodlands and EBMUD intentionally cuts down Eucalyptus and Monterey Pine which are proving themselves more suitable for the environment, it risks a treeless landscape, which would not only be a loss of beauty and loss of wildlife habitat, but exacerbate the challenges already faced by EBMUD as a result of climate change.

We also object to the Draft Master Plan accepting the labels “native” and “non-native” and making decisions based on that fact alone. “Non-native” and “invasive species” are terms that have entered the lexicon of popular culture and become pejorative, inspiring unwarranted fear, knee-jerk suspicion, and a lack of thoughtfulness and moral consideration. They are language of intolerance, based on an idea we have thoroughly rejected in our treatment of our fellow human beings — that the value of a living being can be reduced merely to its place of ancestral origin.

Each species on Earth, writes Biology Professor Ken Thompson, “has a characteristic distribution on the Earth’s land surface… But in every case, that distribution is in practice a single frame from a very long movie. Run the clock back only 10,000 years, less than a blink of an eye in geological time, and nearly all of those distributions would be different, in many cases very different. Go back only 10 million years, still a tiny fraction of the history of life on Earth, and any comparison with present-day distributions becomes impossible, since most of the species themselves would no longer be the same.”

This never-ending transformation — of landscape, of climate, of plants and animals — has occurred, and continues to occur, all over the world, resulting from a variety of factors: global weather patterns, plate tectonics, evolution, natural selection, migration, and even the devastating effects of impacting asteroids. The geographic and fossil records tell us that there is but one constant to life on Earth, and that is change.

Even if one were to accept that the terms “native” and “non-native” have value, however, not only do they not make sense as it relates to Monterey Pine and Eucalyptus, but the outcome would not change for three reasons. First, Monterey Pine and Eucalyptus provide numerous tangible benefits as previously discussed, while the claimed “problem” of their foreign antecedents is entirely intangible. That a plant or animal, including the millions of humans now residing in North America, may be “non-native” is a distinction without any practical relevance beyond the consternation such labels may inspire in those most prone to intolerance; individuals, it often seems, who demand that our collectively owned lands be forced to comply to their rigid and exiguous view of the natural world. What does it matter where these trees once originated if they provide such tremendous beauty and benefit here and now?

Second, the fossil record demonstrates that Monterey Pine are, in fact, “native” to the East Bay. (See, e.g., Monterey Pine fossils from the middle Miocene through the Pleistocene have been found in several East Bay locations. Similarly, since Eucalyptus readily hybridizes with other species, many experts now claim that California Eucalyptus hybrids could rightly be considered native, too.

Of more immediate concern, however, is that the five narrowly defined “native” stands of Monterey Pine — the Año Nuevo-Swanton area in San Mateo and Santa Cruz Counties, the Monterey Peninsula and Carmel in Monterey County, Cambria in San Luis Obispo County, and Guadalupe and Cedros Islands off Baja California in Mexico — are in danger. In light of escalating temperatures due to climate change, to save Monterey Pine requires “a new foundation for conservation strategies of the species and its associated ecosystems. If Monterey pine has long existed in small, disjunct populations and if these have regularly shifted in location and size over the California coast in response to fluctuating climates… then it would be consistent to extend our conservation scope…” “Areas not currently within its [narrowly defined so-called] native range could be considered suitable habitats for Monterey pine conservation.” (Millar, C., Reconsidering the Conservation of Monterey Pine, Fremontia, July 1998.)

As tree lovers and environmentalists in Cambria are banding together to determine how, if at all, they can save their precious remaining Monterey Pines now dying from drought in record numbers, here in the East Bay – less than 224 miles away – land managers at EBMUD are considering plans to willfully destroy them in record numbers. It is ecologically irresponsible and for those of us who dearly love the stunning, even arresting, beauty of these trees, it is also truly heartbreaking.

Third, and perhaps more importantly, removing Eucalyptus and restoring “native” plants and trees is not only predicated on the ongoing use of large amounts of toxic pesticides, it does not work, a fact acknowledged by cities across the country. In the last ten years, the City of Philadelphia has planted roughly 500,000 trees, many of which are deemed “non-native” precisely because “native” trees do not survive. “[R]ather than trying to restore the parks to 100 years ago,” noted the City’s Parks & Recreation Department, “the city will plant non-native trees suited to warmer climates.”

For all these reasons, we oppose the elimination of Monterey Pine and Eucalyptus, even if phased over time as proposed, and likewise oppose EBMUD’s participation in the destruction of similar Pine and Eucalyptus forests in the Caldecott Tunnel area, in partnership with outside agencies. We ask that these be stricken from the Master Plan.

Finally, we oppose the ongoing and, if the trees are cut down, potentially increasing use of pesticides and ask that a ban on their use be put in effect in the final Master Plan, for the following reasons:

● Extremely low levels of pesticide exposure can cause significant health harms, particularly during pregnancy and early childhood.

● Children are more susceptible to hazardous impacts from pesticides than are adults and compelling evidence links pesticide exposures with harms to the structure and functioning of the brain and nervous system and are clearly implicated as contributors to the rising rates of attention deficit/hyperactivity disorder, widespread declines in IQ, and other measures of cognitive function.

● Cancer rates among children are increasing at an alarming rate and pesticide exposure contributes to childhood cancer, as well as other increasingly common negative health outcomes such as birth defects and early puberty.

● Approximately 4,800,000 children in the United States under the age of 18 have asthma, the most common chronic illness in children, and the incidence of asthma is on the rise. Emergence science suggests that pesticides may be important contributors to the current epidemic of childhood asthma.

● Animals, including wildlife and pets, are at great risk from exposure to pesticides, including lethargy, excessive salivation, liver damage, blindness, seizures, cancer, and premature death.

● Pesticides contain toxic substances, many of which have a detrimental effect on animal health, including pets, raptors, deer, and other wildlife, which is compounded when the bodies of poisoned animals are ingested by subsequent animals.

● The U.S. Environmental Protection Agency has recommended non-chemical approaches, such as sanitation and maintenance.

These concerns are compounded by the fact that pesticides are to be administered near reservoirs, threatening the safety and integrity of our water supply and the water supply of the plants and animals who also depend on it. These reasons are why the Marin Municipal Water District removed the use of herbicides from further consideration in its Draft Plan and maintained the pesticide ban it has had in place for several years.

Pesticides are not only dangerous, they are also incredibly cruel. Rodenticides, for example, are opposed by every animal protection group in the nation because not only do they kill animals, but they do so in one of the cruelest and most prolonged ways possible, causing anywhere from four to seven days of suffering before an animal finally comes to the massive internal bleeding these poisons facilitate. This long sickness period often includes abnormal breathing, diarrhea, shivering and trembling, external bleeding and spasms, suffering and death that is perpetuated when their dead bodies are ingested by subsequent animals, such as owls and raptors. Put simply, EBMUD should not be in the business of targeting any healthy animals, trees, and plants for elimination; and doing so by pesticides harms animals well beyond the target species, including humans.

In summary, public agencies overseeing public lands have a responsibility to minimize harm and reject radical transformations of those lands and the ecosystems they contain, especially in absence of any clear public mandate. Not only have these lands been handed down in trust from prior generations for us to enjoy, preserve, and bequeath to future generations, but there is a reasonable expectation on the part of most citizens that those overseeing our collectively owned lands not undertake agendas to destroy large numbers of healthy trees, kill healthy animals, and poison our environment. Regardless of how Eucalyptus and Monterey Pine trees may be maligned by the extreme few, they are beloved by the many, being in large part responsible for the East Bay’s beauty, iconic character and treasured, shady walking trails and picnic areas.

In the case of EBMUD, this orientation is even more alarming and a violation of the public trust because it elevates the ideological driven, nativist agenda of the few above the agency’s primary mandate and interests of the many: ensuring the integrity and safety of our water supply and the plants and animals who reside there. Adopting plans to alter pre-existing landscapes through the use of toxic pesticides in order to placate unreasonable and xenophobic demands on lands that contain the public’s precious reserves of drinking water is a deep inversion of priorities.

We respectfully request that these proposed ends and means be stricken from the Master Plan.

Very truly yours,
Save the East Bay Hills

Barn Owls in Glen Canyon

2016-07-26 (2)

Did you know that Glen Canyon has Barn Owls (Tyto Alba) as well as our famous Great Horned Owls?!  Barn owls are much smaller than the cat-sized Great Horned Owls, weighing just over a pound and reaching about a foot in length. Their wingspan reaches over a yard.

Compare this to our Great Horned Owls whoooo [misspelling intended] can reach a length of 25 inches, weigh anywhere from two to six pounds, and have a wingspan of 5 feet. Great Horned Owls are considered “true” owls whereas Barn Owls are classed differently as Tytonidae.

Barn Owl (Tyto Alba). Their huge eyes don’t move in their sockets like ours do, so an owl must move it’s entire head, rather than just its eyes, to see things clearly. This owl is twisting its head to examine me. Their eyes are no good during the too-bright-light-for-them-during-daylight, so it’s also squinting.

This owl is twisting its head to examine me. Their eyes are no good during the too-bright-light-for-them-during-daylight, so it’s also squinting.


Although they usually glide and “moth their wings” without a trace of sound, Barn Owls can also be quite noisy, as when they really bat their wings loudly on purpose to scare off an intruder, or when they are vocalizing. It is because of their noise that I recently ran into some. I was really surprised when the squawks I heard turned out not to be those of a nearby bluejay warning off the owls. No, it was the owls themselves protecting a youngster! Barn owls, it turns out, don’t “whoo, whoo, whoot”, as we all might expect, as the Great Horned Owls do. Instead, they screech in a bunch of different ways. I made a recording of the sounds:

Press here for AUDIO: Notice there are a couple of distant coyote barks at the 34-39 second marker, and the owls get really intense at the 2:54 marker. The recording lasts 3:24 minutes.

For years I’d seen one at dawn or dusk, gliding and swooping in its silveriness, ever so silently through the dark. You could only see them as you do the bats — against the lighter night sky before total darkness set in in the evening, or before the light of day set in at dawn, or as a shimmer against the darker trees at these twilight hours.

Once, I lay down on the ground and was able to capture, in a photo, one of these owls as it “mothed” right above me, from what seemed like five feet away, examining me out of curiosity — no, it was not courting me! It was because that owl was against the lighter sky that the camera was able to capture its image — it was actually dark outside.

They are nocturnal, so if you want to see them you should begin your walk in the dark — and keep your eyes on the sky above the tree-line: you may see one floating silently by before returning to its roost at dawn, or as it begins its “day” hunting at dusk. I’ve Googled some interesting information which I’ve added below.

Barn Owl "moths" over me

Barn Owl “moths” over me

Territoriality. Barn Owls defend the area around their nests, but they don’t defend the area where they hunt from others of their same species — they share. In other words, more than one pair of Barn Owls may hunt on the same fields.

Contrast this with the Great Horned Owls who live in the same parks as the Barn Owls but who are very territorial: only one mated Great Horned Owl pair and their offspring live and hunt in any one area. Their territoriality which excludes other Great Horned Owls actually places a limit on the number of breeding pairs in any given area. Great Horned Owls who haven’t been able to establish territories are known as “floaters” — they live along boundaries of established territories.  In fact, it may be that just the male Great Horned Owls defend the territories. They are known to kill each other in territorial conflicts, and sometimes resort to cannibalism. Not the Barn Owls!

In the summer, the Barn Owls’ home hunting ranges are a little over a square mile; in the winter they can be many times larger. If food is extremely scarce, both of these owl species might move out of their established territories, but there is no annual migration and they maintain their territories for life.

Nesting. I found out that most Barn Owls mate for life — they are monogamous, as are Great Horned Owls — though there have been reports that some males have had several female mates at the same time. And Barn Owls tend to use the same nest site year after year. One of their courting displays is hovering in front of the female in a “moth-like fashion” — Oh, I experienced this several years ago! Chicks usually start flying at 9-10 weeks and begin leaving the nest for good at about 11-12 weeks. All will probably be gone by 14 wks.

If there is nesting in July, as is the case with this find of mine, it’s usually a second clutch for the mated pair. About 10% of barn owls reproduce two times a year — and some even produce three clutches in a year! And, although the breeding season is considered from March to August — having expanded due to climate change from an original breeding season which was almost always in May — they, in fact, can produce youngsters at any time of the year.

They lay as many as 6 eggs, but more often than not, only about 4 of them hatch. The eggs are laid asynchronously, every 2-3 days and they hatch in the order in which they were laid (sounds like a business telephone answering service, doesn’t it?!). So chicks from the same clutch can actually vary up to about 21 days in their ages. They don’t “build” nests, but find places to lay their eggs which they line with their pellets.

Owl Pellet -- Guano dripping down a tree trunk -- Great Horned Owlet spitting up a pellet

Owl Pellet — Guano dripping down a tree trunk — Great Horned Owlet spitting up a pellet

Poop. Pellets are actually excrement regurgitated through the mouth. Owls swallow their prey whole, but they don’t digest the bones and fur. The parts of the prey that actually pass through the digestive tract and out of their rumps are excreted as a softish, whitish “guano” — like that of all birds. Guano can often be found dripping down the tree trunks on which they perch.

However, in owls the larger, indigestible parts of the prey, including bones and fur, are kept in their gizzard for a couple of hours as a pellet which then travels back up into the Proventriculus (the first part of the stomach) where it remains for ten hours before being regurgitated. This stored pellet actually blocks the owl’s digestive system so that new prey cannot be swallowed until the pellet is ejected. Twice a day these are spat-up, or regurgitated out of their mouths, as “pellets”. These pellets basically look like the poop of other animals except that they are oval-shaped and not long. [see Digestion in Owls]

Hunting. All owls’ eyesight is pretty superb — they hunt at night [see “Coyote Night Vision”]. In addition, the ability of Barn Owls to capture prey by sound is the best of any animal that has ever been tested. Their satellite-dish shaped faces helps with this. They eat mostly small mammals such as rats, mice, voles, gophers. Also bats. They don’t eat squirrels so much because they are less active at night. They also eat some song birds. 91% of barn owls, post-mortem, are found to contain rat poison. The most long-lived Barn Owl ever recorded was 15 years old.

Poisons. Everyone, please don’t use poisons to eradicate rats, and please ask your neighbors to do the same. Rat poison is a horrible and slow death for rats, causing them to bleed from the inside out, and causing them to become disoriented and slow. This is why owls catch them. But worse, the poison actually travels up the food chain to these owls. Several years ago I sent in two dead barn owls for toxicity tests: they were found to have huge amounts of rat poisons laced throughout their bodies. We’ve also had a number of our Great Horned Owls killed by rat poisoning: One, this year, we guessed, was the mother of owlets who then never made it to adulthood.

Who is Funding the Campaign for Prop B? (And, Ooops!)

find the moneyYou’re probably going to see lots of material in support of Proposition B (the 30-year, $4.65 billion set-aside for park funding with very little oversight on how it’s spent). They have a war-chest of nearly $400 thousand to promote this measure. Where’s the money coming from?

More than half of it is from two sources:

  • The San Francisco Parks Alliance ($101 thousand) and
  • “Committee to Expand the Middle Class, Supported by AirBNB Inc.” ($100,000).

Other funders include  developers, investors, and construction companies. Here’s the list, provided by a San Franciscan who obtained it from the Ethics Commission.

In related news, the Controller’s Office made an error in its statement in the Voter Pamphlet. It says that the spending would be overseen by the Board of Supervisors. It won’t. Here are the details (from the No On B campaign):

specman-mdMany of us have been concerned about the Controller’s Statement in his letter in the Ballot Pamphlet, in which the next to the last paragraph reads:

“The proposed amendment requires Recreation and Parks to set goals and measures, develop a five year strategic plan and set operational and capital spending plans. The plans must be approved by the Recreation and Parks Commission, the Mayor and the Board of Supervisors.”

However, the legislation actually states:

  1. 7  lines 21-25  “Following Commission approval of the Strategic Plan [also Capital Plan], the Department shall submit the Strategic Plan to the Mayor and the Board of Supervisors. The Boards of Supervisors shall consider and by resolution express its approval or disapproval of the Plan, but may not modify the Plan. If the Board expresses its disapproval of the Plan or makes recommendations regarding the Plan to the Department, the Department may modify and resubmit the Plan.”

After being contacted about this error, the Controller issued a correction (attached):

” Upon further review of the proposed amendment, I would like to clarify the approvals required for the five-year strategic plan and annual capital expenditure and operational plans as outlined in my March 11, 2016 letter. The Recreation and Parks Commission must approve these plans prior to submitting them to the Mayor and the Board of Supervisors for review and comment. The Board of Supervisors can approve or disapprove the five-year strategic and annual capital expenditure plans, but may not amend the plan. If the Board disapproves, the Recreation and Parks Department can modify the plans. ”

“This clarification does not impact my earlier assessment of the proposed amendment’s cost to government, as outlined in my March 11, 2016 letter. ”

As we all know, “can” is not the same as “shall” and so under Prop B Rec and Park has the freedom to create and modify their plans, without BOS authority to modify those plans.

We urge all city departments and homeowners to trim or remove trees only in the safe Fall months: September to December



I learned a valuable lesson this weekend: Do Not Prune or Remove Trees in Spring!

Over the past couple years, I’ve been removing a row of unattractive honeysuckle trees along the fence line to let more light into our shady yard and plant some ferns & other foliage. The trees all had long skinny bare trunks with foliage starting at about 15- 20 feet up so all I could see was fallen leaves on top of compacted dirt and 8 pencil-thin tree trunks.

This weekend 7 and 8 were scheduled for removal. After getting 7 out of the ground, root and all, my friend and & I were getting ready to start breaking the trunk & branches down to 4 foot size segments required by the city for the green waste bins. I had a hand saw and my friend was using my mini electric chain saw for the job. I kept a safe distance in a far corner of the yard and we got to work. 2 branches into it, the chainsaw turns off and I hear “Oh Noooo! Oh my god! Nooo!” then, “chirp, chirp chirp”!

The tree had a hummingbird nest camouflaged and expertly woven very securely onto a few twig size branches. Both my friend and I love & respect nature so we were a little frantic and horrified at the thought of nearly chainsawing through this little womb-like nest cradling 2 chicks. I found a little box and cushioned it with soft material scraps and toilet paper and placed the nest inside very carefully. It took a good hour for us to calm down and stop focusing on how thoughtless we had been to choose April to remove a tree. Even ugly trees with sparse foliage provide habitat and serve a s food source. My friend, a somewhat burly guy named Terry but whose friends call him “Bubba” was on the verge of tears telling me, “I searched for a nest before sawing off each branch. . .” . Even if one of us has noticed it, it did not resemble a typical storybook nest.
I called every organization and person I could think of for help on that Saturday evening: Golden Gate Audubon Society, Wild Care, and Janet. I was able to listen to a recorded instructions for caring for a injured chick. I kept them inside for the night in a warm dark spot away from my curious little dog who likes to be a part of everything I do whenever possible. As soon as it was light outside, I placed the box up high in the area where the tree had been. Within 20 minutes, mom showed up and fed her hungry babies and I watched as she gathered nectar from the flowers overhead on tree number 8 (which will stay in my yard).

DAY 1: a few hours after discovery

We estimated the age to be between 2 & 3 weeks and were told that hummingbird chicks leave the nest at 23 days old. A couple days before this happens, a stronger chick pushes the weaker out of the nest and it dies because mom will not feed it on the ground. The reason this happens is because the nest is very small and is needed as a “launching pad”. Once the other chick takes flight, mom will continue to feed her baby for several days, teaching how and where to find all the best nectar & bugs before she chases it away to find its own territory. Since they are in a box, neither one will be pushed out of the nest and mom will continue to feed them both. I’m not sure if this may have any negative or unforeseen consequences but I like that idea!

Day 3: I wasn’t sure if Mama was feeding her chicks with the new placement of the box with a different type of access, but I caught her in the act (see video below)

Day 5: Just before I left late Thursday morning, I went to check on the chicks and snapped this photo. They looked like they were ready to spread their wings. I might have made them a little nervous putting the camera up so close but wondered if they were contemplating their first flight.

When I came home in the early evening, the first thing I did was check the box and it was empty. I stood there for several minutes wondering how such a tiny creature with only 23 days of life can survive on their own. That’s when I heard chirping above and looked up- there was mama with 1 chick shoulder to shoulder on a branch.

hummingbird-in-wire-2I looked around for the other chick and had noticed what I thought was a leaf caught in one of the links on the fence, but a closer look told me otherwise.

Maybe the little guy didn’t feel quite ready, or maybe he wanted to say goodbye. He let me get real close and looked at me with that one little eye as I said some encouraging words and slowly reached in my back pocket for my camera. I snapped one photo and he flew to the branch up above where his family was.

Today would be Day 8. I’ve been seeing what I believe to be this same little chick hanging out in the honeysuckle tree where the box was. A few hours ago, I observed the mama arrive and feed the chick patiently waiting on a little branch.

If you would like to invite hummingbirds to your yard I would not recommend those feeders with sugar water because they must be cleaned every 3- 4 days or they can make the hummingbirds very sick. It’s much better and healthier to provide their natural food sources and plant things like honeysuckle, sage, fuchsia, Aloe vera and other long tubular flowers that provide both nectar as well as habitat for insects that serve as protein. Hummingbirds also need a place to perch during the day & sleep at night that offers some protection from wind & rain- usually trees. You can also hang a perch up high in a tree near the flowers and you can encourage nesting by providing materials by hanging a “Hummer Helper” you can purchase and fill with store bought material or even dog and cat hair — the “Hummer Helper” is actually just a “suet feeder” which you can buy for a lot less. The best time to start is May. The Hummingbird Society has a lot more tips and information on their website.

*One last note about trimming trees- the safest time is in the Fall during the months of September- December

What’s Wrong With Proposition B? (San Francisco Rec & Parks Slush Fund)

sack of gold[Edited to Add on 26th April 2016: The website of opponents to Prop B keeps a running tally of groups opposing the Proposition. HERE is the link:  ]

The San Francisco Forest Alliance opposes Proposition B.  Initially, Proposition B, Supervisor Mark Farrell’s Charter Amendment, looked like a good idea.  The thinking was that it would guarantee funding to San Francisco Recreation & Parks Department (SFRPD) for improved maintenance, and focus on under-served parks. There’s a big push on right now to sell this idea to potential voters. But (and it’s a very big but) the way it’s written essentially hands the money to SFRPD with no meaningful restrictions on how the money will be spent.

The text of the amendment, as a PDF,  is HERE: Prop B text PDF

The short description of the measure from the ballot simplification committee is HERE: PropB-OpenSpaceFund-Digest PDF


Natural Areas Program pesticide noticeProposition B would set aside money from the General Fund for the Parks Department. It doesn’t raise extra money, it just makes it compulsory to set aside part of the city’s budget and give it to the SFRPD to spend how they will. What the money is actually used for would be entirely at the discretion of the General Manager of SFRPD, who is selected by the Mayor. SFRPD is nominally overseen by the Recreation and Parks Commission, but the Commission, also appointed by the Mayor, nearly always supports the General Manager. The result is a Department Manager and a Commission that align with each other and the Office of the Mayor.

Proposition B removes the Board of Supervisors from the Parks’ budget process. During the budget process, the public gets to weigh in at hearings and with their Supervisor on their parks and what is needed. (At present, the Board can influence SFRPD because the Board decides how much funding the Department gets from the General Fund each year.) Proposition B mandates that funding go to SFRPD,  so it removes that control of public money from the public and from our elected Supervisors and gives it to political appointees and bureaucrats.

Though Proposition B is being promoted as favoring maintenance and social justice, there’s no mechanism in the Amendment by which to enforce either of those goals. The BOS is allowed to comment on SFRPD plans and goals, but it will have no authority to change them.

There is no specificity in Proposition B as to how this money will be spent. If some future General Manager decided what he really needed to do was to increase middle management to privatize parks and clubhouses, boost managerial salaries to compete with Silicon Valley, hire contractors to douse the parks in herbicides, or make our parks into elaborate and expensive showpieces that end up excluding the neighborhood residents – as happened with the Mission Playground – there would be nothing outside of the Department to stop him. The Mayor could select a different General Manager, but again, all of the power is exclusively in the hands of the Office of the Mayor.

It’s for 30 years. Mayor Ed Lee and SFRPD General Manager Phil Ginsburg will be in charge for only a small portion of the amendment’s life. The people who will be running things at the end of this period are probably in kindergarten right now.


Prop B guarantees funding for the Natural Areas Program.  Here’s the language:

“The annual budget for allocation of the Fund that is adopted by the Commission and submitted by the Mayor to the Board of Supervisors shall  include: 1. Allocations for after-school recreation programs, urban forestry, community gardens, volunteer programs, and a significant natural areas management program in the amounts allocated for each of those programs from the Park and Open Space Fund in the Department’s fiscal year 2015-2016 budget, to the extent that such programs are not so funded in the Department’s operating budget or in the budget of another City department.”

felled-trees-lake mercedThis means that when they decide to fell 18,500 trees, when they want to close 9 miles of trail and many dog-play areas, when they decide to use toxic chemicals to eradicate non-native plants they dislike – they’ll have the money and can go right ahead. Neighbors who object will have to fight them park by park, action by action.

(The actual Significant Natural Resource Areas Management Plan (SNRAMP) is on hold because the Environmental Impact Report has not even been published and  approved yet. That’s because the Draft received so many negative comments they needed years to respond. Though SFRPD appears to be implementing much of what’s in that Plan already.)


If SFRPD gets more money from the General Fund, someone else gets less. Proposition B would impact funding for other City departments. By mandating money for SFRPD, it reduces the amount of money available for other uses. The Board of Supervisors  wouldn’t be able to use the money to meet emergency needs for the City and for other City enterprise departments – not even agencies that provide social services and other public benefits. They will have to scramble for allocations from the remaining discretionary General Fund . Soon every department will need set-asides, and our elected officials will have a declining say in how public money is spent.


It’s also going to be a lot of money – as much as $4.56 billion (yes, billion with a B) over the thirty years. According to an analysis provided to us, here’s how it works:

1. The baseline is the current expenditure of $64 million. It will increase by $3 million each year for the next 10 years, and the new amount will become the new baseline each year. So $67 million in 2016, $70 million in 2017, and so on for 10 years, by which time it would be $94 million.

2. Starting 2026, the $3 million stops. Instead, the addition to the baseline will depend on the city’s revenue growth. It will grow the baseline by the same percentage as the increase or decrease in city revenues. So if the revenues grow 2%, so will the baseline.

3. In addition, there’s the Open Space Fund. It’s 2.5% of property taxes, and Prop B extends it for another 15 years. Theoretically, this is used to acquire land for open space. In fact, it’s also used for other purposes. This adds a minimum of $48 million a year that is reserved to SFPRD for its own purposes. As  property taxes rise, so will the Open Space Fund.

Over 30 years, this would total an estimated $4.56 billion.  (You can see the calculations – provided to us by an analyst opposed to Prop B – HERE: RPD Funding 2016 Charter Amendment – with GF 2 percent +totals now )

SFRPD also gets income from its fees, leases, and permits. That funding would continue on top of all of the funding guaranteed by Proposition B.

Opposing Proposition B will not deprive SFRPD of any funding. They can still make a case for their needs during the budget process on an equal footing with every other department to the people and to the Supervisors.

So – in brief: What’s wrong with Prop B is that it sets aside a sizeable, untouchable slush fund with no real accountability and no control from outside of SFPRD – and it’s one that will operate long after the professional life-times of those who are setting it up.

If You’re a Sierra Club Member…Important 2016 Election

mg_ecowatch_3536 east bay expressIf you’re a Sierra Club member, you’ve probably received a message asking you to vote for the Board of the Sierra Club in the 2016 elections before April 27th 2016.  There are 8 candidates for 5 positions: see them HERE. There are some questions that the Club asked the candidates at the same site, none of which speak to our concerns.  But a Sierra Club member wrote to the candidates asking the important questions. So far, 5 replies have come in. The questions:

  • What is your opinion of destroying non-native trees?
  • What is your opinion of pesticide use in public parks and open spaces?

The San Francisco Forest Alliance stands for trees and habitat, and against pesticide use in parks. We also believe in access, and in sensible priorities and transparency in use of public funds. The Sierra Club, horrifyingly, supports projects in the San Francisco Bay Area that would cut down hundreds of thousands of trees, and use tons of pesticides on high ground. Here’s our subjective assessment (the actual candidate statement is given below) on a scale of 1-5 (Bad to Good).

  • Susana Reyes: On trees 4; On Pesticides 5; Total 9 – Recommend
  • Judy Hatcher: Trees 3; Pesticides 5; Total 8 – Recommend
  • Robin Mann: Trees 2; Pesticides 2
  • Mike Brien: Trees 1; Pesticide 3
  • Luther Dale: Trees 1; Pesticide 1 (Since his response takes no position, we can only assume he would not oppose the appalling East Bay projects.)

You can see their detailed responses below, and decide for yourself.

There’s been no response so far from Chuck Frank (an incumbent up for re-election), Joseph Manning, or David Scott.

We have joined a petition to ask the Sierra Club not to support this egregious project. If you have not signed the petition, it’s HERE: Sierra Club must STOP advocating for deforestation and pesticide use in San Francisco Bay Area. Please sign if you haven’t already. It’s got over 2,500 signatures! (In comments, please mention if you are a Sierra Club member, present or past.)


Susana Reyes (currently Secretary of the Board)
“Just the mere thought of cutting a tree upsets me greatly. I can’t offer a position about destroying non-native trees without considering the different factors that may come into play – like climate conditions, types of landscape, threats to biodiversity, invasive or not, fire threats – just to name a few. It also depends on the land management practices in the areas where non-native trees exist. There ought to be other options to destroying non-native trees. I would think very carefully about destroying non-native trees especially if only a fraction display traits that harm or displace native species and disrupts the ecological landscape”.

“I strongly oppose pesticide use in our parks and open spaces. I am all too familiar with herbicide “Roundup” for example and its use to stop unwanted plants. Another one is rodenticide which is used to kill rats in parks/open spaces. In Los Angeles, our beloved mountain lion, P22, who calls Griffith Park home, was sickened last year with mange as this poison worked its way up the food chain. Many of the chem Research has shown links to certain types of cancer, developmental disorders, and physical disabilities. Pesticides end up in our drinking water, watersheds, and rivers/lakes. The use of toxic pesticides to manage pest problems has become a common practice around the world. Pesticides are used almost everywhere and therefore, can be found in our food, air, and water.”

Judy Hatcher:
“As you probably noticed from my candidate profile, I’m the Executive Director of Pesticide Action Network, so I’m not in favor of pesticides–especially highly hazardous ones–in public spaces or anywhere else. I think the issue of non-native trees is specific to particular contexts and environments. But it’s unfortunate that the damage non-native plants and animals cause lead communities to demand increased use of pesticides and herbicides, which have negative consequences for human health as well as for the natural environment. PAN focuses on industrial agriculture, so we don’t do a lot around non-native plants except for how they impact farming (hello, RoundUp!).”

Robin Mann (currently Vice President)
“Let me just note that I am running for reelection to the Board because I believe I can contribute to the Club’s progress towards its major goals for the environment and for ensuring a strong and effective organization into the future.

Being a strong and effective organization, in the case of the Sierra Club, requires among other things ensuring a broad and engaged grassroots presence everywhere. And we know that strong grassroots engagement necessarily means people coming together to resolve local issues that often have competing considerations. Our policies and our approach generally allow some latitude to ensure the local context is being taken into account. I wouldn’t want to try to dictate the solution for all situations.

My understanding from my work with the Club’s efforts to strengthen resiliency in the face of mounting climate change impacts is that restoring native vegetation is desirable, and can contribute to restoring greater ecological balance. And my understanding from my work on the ground with organizations doing habitat restoration is that sometimes HERBICIDES are needed as a last resort to enable newly planted natives to become established.

If you are speaking of herbicides being used in public parks and open spaces, my view is they generally should not be used for maintenance purposes as non-toxic alternatives are available. For habitat and vegetation reestablishment I would defer to those designing the project with the expectation that herbicides would be minimized, used responsibly, and any exposure to park users avoided.

If you are speaking of pesticide use for insects or other “nuisance” species, I expect that in most instances a non-toxic management alternative is available, and so the burden should be on the public entity to justify use of a pesticide for maintenance purposes.”

Mike O’Brien:
“I have strong concerns about invasive species crowding out and changing native ecosystems in detrimental ways. That said, we have already made significant and irreversible impacts to many ecosystems. I don’t believe a policy of eliminating all non-native trees simply because they are non-native makes sense at this point. Rather, it should be taken on a case by case basis where we consider what the impacts are of the non-native species and any work should typically be done in conjunction with a plan to restore native trees and habitat.”

“Strong preference to zero use of pesticides. There have been occasions where serious threats from invasive species have proved practically impossible to overcome without targeted use of pesticides, but this should be a rare exception as opposed normal operating procedure.”

Luther Dale:
“I have to say I do not know the context of these issues nor knowledge sufficient to give you a good answer. There are so many environmental issues and I accept that I can’t be knowledgable about them all. I do know a lot about some issues and know how to listen and learn about issues new to me. Thanks for your passion about these and other environmental problems and for your work to care for the earth.”
