Mt Davidson: Tree Destruction Imminent?

There’s a lot of activity at the Juanita entrance of Mt Davidson, and neighbors fear the San Francisco Recreation and Parks Department (SFRPD) is rushing through its tree-felling program. At a time when we need trees more than ever to fight climate change, and mudslides in Southern California illustrate the devastating effects of destroyed trees and vegetation, this would be egregious.

Here’s a note from a forest-lover:

What I’ve seen so far as of last week is preparation and road, trail widening with landing areas for equipment, but no big cuttings or equipment in the interior yet. Just the one big landmark, living tree marked with dots, and all the prior destruction.”

Do these dots mark this iconic tree for killing?

TRAILS BEING WIDENED FOR HEAVY EQUIPMENT?


What equipment will go up here? Maybe a “Brontosaurus”?

TREES DESTROYED EARLIER

Tree have been destroyed on Mount Davidson some years ago, and this prior destruction gives some idea of what the desired end-condition is for the next round. The so-called “boneyard” has stumps of dead trees.

 

This tall mature tree was “girdled.” That’s a process of destroying cutting a deep ring around the tree, so that food and water cannot be transported and the tree starves to death.

A beautiful green and flourishing tree that provided food and habitat for birds, and brought joy to forest lovers, is a dead skeleton.

THE BEAUTIFUL FOREST WE ARE LOSING

The lovely forest we are losing is beautiful and historic, and provides habitat for a huge number of birds. But it’s not just beauty and habitat. These trees provide important eco-system services.  Some examples:

  • They stabilize the mountain, with their intergrafted roots forming a living geo-textile. The horrible mudslides in Southern California illustrate how important this is.
  • They fight pollution, especially pollution from particulate matter, by trapping the particles on their leaves until rain or fog drips them to the forest floor where they are not in the atmosphere – or our lungs.
  • They form a wind-break in what would be one of the windiest areas of the city, with the wind blowing in straight off the sea.
  • They regulate water flows, so that when it rains hard, the forest acts as a sponge, absorbing the water and letting it flow out gradually.
  • They catch moisture from the fog during summer, making the mountain damp and reducing fire hazard.

Please let City Hall and SFRPD know that you want this forest protected and saved, not gutted. The plan is to remove 1600 trees!

[Update 1/19/18:  We spoke with the contractor on site. Seven trees have been cut down, and that completes this contract. Hopefully we will have more public notice and explanation if other tree removals are planned.]

Important Pesticide Meeting at City Hall, 20 Dec 2017

Toward the end of each year, SF Department of the Environment (SF Environment), which runs the Integrated Pest Management Program (IPM) holds an important public meeting. This year, it’s on December 20, 5-7 p.m. in Room 400 at San Francisco’s City Hall.

This meeting is to discuss three things, and take public comments and input: Changes to the approved list of pesticides for city use; the guidelines for pesticides use and public notification; and explaining the exemptions granted in 2017 to the rules.

Pesticides used on blackberry on Mt Davidson – Nov 2017

THREE THINGS ON THE PESTICIDE MEETING AGENDA

1. Changes to the approved list of pesticides for use on city properties. SF Environment publishes a list of pesticides that are okay to use on city-owned properties (our parks, lands owned by the Public Utilities Commission, Crystal Springs, the airport, Sharp Park and a few others). It divides these permitted pesticides into three tiers: Tier III (Least Hazardous), Tier II (More Hazardous) and Tier I (Most Hazardous). This meeting discusses pesticides added, removed, or having their Tier classification changed.

The DRAFT for 2018 is here: b_draft_2018_reduced_risk_pesticide_list

2. Guidelines for pesticide use and public notification. Over the last year, IPM has been trying to develop guidelines for when and where these pesticides are prohibited; and also for how the public can be informed when pesticides are used. Here’s the current DRAFT of the guidelines: c_summary_of_major_changes_to_2017_restrictions_of_most-hazardous_herbicides

3. They also explain the exceptions they’ve granted in the previous year, i.e. 2017. They approved 21 exemptions in 2017. The list of exemptions is here: a_summary_of_pesticide_exemptions_for_2017

The one that particularly concerns us is permission to use Garlon 4 Ultra (probably the most toxic herbicide still permitted on City properties) on oxalis within fifteen feet of designated trails at Twin Peaks, Mount Davidson, McLaren Park, Bayview Hill and Corona Heights.

They argue: These parks have a diversity of native plants growing adjacent to trails including but not limited to: Grindelia hirsutula (gumplant), coast rock cress (Arabis blepharophylla), Pacific reed grass (Calamagrostis nutkaensis), stonecrop (Sedum spathulifolium), meadow white (Cerastium arvense), silver bush lupine (Lupinus albifrons), Mission bells (Fritilaria affinis), footsteps of spring (Sanicula arctopides), California buckwheat (Erigonium latifolium), soap plant (Chlorogalum pomeridianum), dichondra (Dichondra donelliana), varied lupine (Lupinus variicolor), California buttercup (Ranunculus californicus), checkerbloom (Sidalcea malvaeflora), campion flower (Silene scouleri) and coast red onion (Allium dichlamydeum). Many of these plants are considered sensitive species and some of them support important local wildlife, such as the lupine species that are host plants for the endangered Mission blue butterfly (Icaricia icariodes missionensis). SFRPD is obligated to manage the land at Twin Peaks for the Mission blue butterfly as part of the Recovery Plan with the U. S. Fish and Wildlife Service, including the management of oxalis. In recent years, Garlon 4 Ultra is being used to protect these sensitive areas from this invasive weed. The Oxalis pes-caprae is a major threat to the existing biodiversity of wildlife within the native grasslands. If left untreated these areas will greatly interfere with the progress already made in controlling this particular weed.

What it boils down to is the poorly-supported theory that oxalis will take over the world if they let it, an argument Nativist doyen Jake Sigg recently made in his newsletter while defending pesticide use. “Our most serious destroyer of biological diversity is the yellow oxalis, Oxalis pes-caprae. Because it is prolific, aggressive, and effectively practices chemical warfare, it is pushing out native species—the wildflowers that so delight us and which are needed as the base of the food chain for other creatures. Because it can’t be destroyed unless the bulb is killed, herbicides are mandatory.”

By contrast, actual research indicates oxalis is a poor competitor, and even the California Native Plant Society California Invasive Plant Council considers it only moderately invasive (mainly in sand dunes). [Edited to correct the organization reference.]

We understand that some opinions are influential even when opposing evidence surfaces, but in this case the tradeoff is the continued use of the most toxic herbicide that the city allows on its land. We’ve argued before that this tradeoff is not good for people, wildlife, or the environment. (See our presentation-format post: Garlon v. Oxalis in 10 Easy Slides ) We certainly do not wish it to be used near any trail where people go out with their kids and pets.

WE STAND FOR NO TOXIC PESTICIDES IN OUR PARKS

San Francisco Forest Alliance stands for an end to toxic pesticides in our parks. This can be done; the Marin Municipal Water District stopped using herbicides altogether some years ago. It means having a more practical approach to managing the landscape, and not declaring war on various species of plant.

However, we do have some concerns. Here are notes from Tom Borden, a public access advocate:

2017 exemptions
There is only one exemption from the posting requirements. It is for PUC right of ways. I understood pesticides were used at the GGP plant nursery without posting. Where is the exemption? I suspect herbicides are applied above the reservoir at 7th and Clarendon without posting. Where is the exemption for that?

Restrictions on Herbicides for City Properties
A2  Why are applications done by methods other than spray exempted from the requirement to use blue dye? If a stump has been daubed rather than sprayed, how will people know it’s not safe to sit on?

A2  Why say, “or in cases where posting is not otherwise required under the law”? Posting is always required by law, unless an exemption from posting is granted by IPM. Right now there is only one posting exemption on the IPM Exemptions log. If and when IPM issues another posting exemption, the land manager can also request an exemption from the blue marker dye requirement if there is a good reason to avoid the dye. Who does not want to use blue dye? Is it really expensive? Isn’t it beneficial to the people applying herbicides to be able to see what they already treated? Why shouldn’t people be able to see what was treated?

A7  Why can’t herbicides be used on green walls and green roofs? Whatever that logic is, why doesn’t it apply more broadly?

B9  Why don’t the protections for the public and employees extend to areas outside city limits? Do we only care about people in San Francisco?

B9  What is the relevance of public accessibility? The Chapter 3 of the San Francisco environment code protects City employees as well as the public. If “publicly inaccessible parcels” are to have lesser requirements for posting and demarcation, the law requires that the land manager apply for an exemption. As of today, there is only one posting exemption on file, for PUC rights of way. There should also be one for the GGP nursery. Other than that, we are not aware of any other “publicly inaccessible parcels” in the City. The general exception for “publicly inaccessible parcels” should be removed. It just introduces unnecessary ambiguity. If there is a genuinely publicly inaccessible parcel, and City employees can be protected, then IPM can issue an exception for that.

B9  Why are golf courses and areas managed for habitat conservation afforded less public protection? Don’t golfers, kids and hikers deserve protection too? Maybe the behavior of golfers is predictable, but people enjoying our wild parkland could be having a picnic, playing hide and seek, exploring, rolling down a hill, doing almost anything. There should be no exception to the demarcation requirements for “areas managed for habitat conservation”.

B12  If a trail exists, especially one not “actively maintained by City operations”, it is because people use it frequently. If the intent of these rules is to protect the public, all trails should be afforded the same protection. If the intent of these rules is to make life easy for land managers and punish people who use un-designated trails, you are on the right track.

B13  Please remove spray boom “definition” for broadcast spraying. The last part of the second sentence gets to the point, broadcast spraying means indiscriminately spraying all plants in an area, as opposed to targeting specific plants. In 2016 you saw video and photographic evidence that three men with backpack sprayers can perform broadcast spraying. Please use the definition for broadcast spraying that the rest of the world uses.

New thinking on Tier I
The new Restrictions do away with the idea that Tier I herbicides are only to be used when there is a critical need. Now Tier I can be used for anything except for prohibitions 10,11 & 12. The old restrictions limited where Tier I herbicides could be used based on a “need” that was balanced against the risks of use. Where has that gone? This seems like a real step backward.

Now land managers just need a reason that goes beyond cosmetics and they can apply Tier I herbicides anywhere as long as it is more than 15 feet from an area frequented by children and more than 15 feet from the land manager’s designated trails.

While we work toward the “No toxic pesticides in our parks” goal, we try to attend these meetings and believe that we have been able to work with SF Environment over the years to get some improvements.

  • SFRPD improved the signage for pesticide use, and is now encoding the use of colored dye to show where actual spraying has taken place.
  • More practical restrictions on pesticide use.
  • We’re encouraged by SF RPD’s reducing herbicide use in the last three years – excluding the Natural Areas (now the Natural Resources Division) and Harding Golf course, which is managed under contract by the PGA Tour. (The graphs below show pesticide usage by SFRPD ex NAP and Harding, and NAP/ NRD’s pesticide use. Please note that all measurements are in fluid ounces of active ingredient, but the scale on the two graphs are different.)

Pesticide Use in San Francisco Natural Areas Creeping Up Again – Oct 2017

We’ve received the pesticide usage reports for the first ten months of 2017, and we’re concerned. After reducing herbicide usage in the last four years, it’s creeping up again in the natural areas. The Natural Areas (now called the Natural Resources Department) has already used more herbicides (measured by active ingredient) than in all of 2016. It hasn’t reached 2015 levels, but park users hoped for further reduction, not an expansion in herbicide use.

San Francisco’s Department of the Environment runs the Integrated Pest Management (IPM) program for city-owned properties in San Francisco. It publishes an annual list of permissible pesticides, and classifies them into Tier III (Least Hazardous), Tier II (More Hazardous) and Tier I (Most Hazardous.)

The unnaturally-named Natural Resources division (NRD) of the San Francisco Recreation and Parks Department (SFRPD) used more Tier I  herbicides than the rest of SFRPD put together (excluding Harding Golf course, which is managed under a separate PGA contract – but including all the other city-owned golf courses). In fact, in the first ten months of 2017,  NRD used 69% of the Roundup and 100% of the Garlon used by SFRPD.

The parks mainly targeted thus far were:

  • Twin Peaks (sprayed 32 times);
  • Glen Canyon (sprayed 27 times);
  • McLaren Park (25 times);
  • Bayview Hill (14 times); and
  • Laguna Honda (PUC property – 13 times).

Other parks that got sprayed over five times in ten months were Mt Davidson (8 times); Marietta (a PUC property – 8 times); and Lake Merced, also 8 times.

NRD INCREASES USE OF CANCER-CAUSING ROUNDUP 

We especially noted that its usage of glyphosate (Roundup/ Aquamaster) has nearly doubled from 2016 (i.e., in ten months, NRD used nearly twice as much glyphosate as in the whole of 2016).

This is particularly worrisome since Roundup probably causes cancer. We wrote about that in these articles: World Health Organization: Roundup “Probably Carcinogenic” and in this report from an EPA scientist before she died reported on problems with pesticide assessments: “It is Essentially Certain that Glyphosate Causes Cancer”

This is the first time since the report came out we’ve seen an increase in its use.

GARLON IS WORSE

The other major Tier I pesticide being used is Garlon 4 Ultra (triclopyr). NRD is the only section of SFRPD that uses this chemical, which has been considered Most Hazardous and HIGH PRIORITY TO FIND ALTERNATIVE at least since 2009. It’s twenty times as harmful to women as to men. (Here’s our quick presentation on the subject: Garlon v. Oxalis in Ten Easy Slides.)

NRD uses this on oxalis, an early spring-flowering plant beloved of children, pollinators, and wildlife – and the general public, who enjoy its bright blooms as a sign of spring. It’s the only use of Garlon by NRD, and if they abandoned the vendetta against these Bermuda buttercups, they would not need to use this awful pesticide.

NEW WAR TARGETING CAPE MARIGOLD

Meanwhile, there’s a new city-wide war on a naturalized species: against arctotheca, or Cape Marigold. It’s another yellow-flowering plant that grows all over our city’s parks, and it’s on the list of 40 species (and counting) that the NRD wants to poison.  Here’s a picture from McLaren Park (together with Great Blue Heron that’s probably hunting gophers).

Cape Marigold occurs in both a fertile and an infertile form; both are considered only Moderately invasive by the California Invasive Plant Council – as is oxalis.

Unless NRD changes its approach and objectives to naturalized species of plants – and recognizes the need for inclusiveness in natural areas – there is little likelihood of eliminating pesticides from our parks. Aggressive management will inexorably result in increased herbicide use.

WHAT ABOUT THE REST OF SFRPD?

By contrast, the rest of SFRPD (excluding Harding Golf Course) seems to be on track to reduce usage again from 2016. For which kudos!

[Edited to Add: The graph below was corrected to indicate the last column shows usage only through Oct 2017, not the full year.]


The only department besides Natural Resources to regularly use pesticides is the Golden Gate Nursery. They wish to make sure the nursery stock they supply is pest-free before propagating it. This is less of a concern than NRD for several reasons: It’s not a public space, usage is confined in a small area and not on parks and hillsides where chemicals could spread to other areas.

We are concerned, though, that they are experimenting with several herbicides that were not earlier on SF Environment’s list: Axxe, Suppress, Clearcast and Finale. They are all considered Tier II, according to Dr Chris Geiger of SF Environment’s IPM.

Of these Axxe and Suppress seem to be less harmful. Suppress is considered acceptable for organic farming.

Clearcast is more concerning, as is Finale. You can see the Clearcast Label here: clearcast_Label.pdf 2016

Here’s the Finale Label: finale_msds

Both these pesticides have cautions regarding potential harm from immediate exposure. We will further research them, but more than the specifics, we’re concerned at the direction. Rather than working to eliminate herbicides from our parks, SFRPD seems to be looking for substitutes for Roundup. Thus far, these two chemicals have been used only in Nursery areas – the GGP Nursery, and the nursery at the Botanic Gardens.

SFRPD now has five Integrated Pest Management Specialists (compared to one before). This is good news to the extent that they will be working on mosquito abatement and alternatives to rat poisons. It’s bad news if it encourages SFRPD to open new battle fronts (like the war on Cape Marigold), or increase use of herbicides in the water, rather than changing its approach to eliminate pesticides in our parks. Here’s the note about their activities from an October meeting of SF Environment’s Policy Committee:  102317_attachment_c_-_agency_ipm_updates_for_2017

SF Forest Alliance reiterates our commitment to working toward No Toxic Pesticides in our parks. We recognize that it will be an uphill battle, as all current interests are in continuing pesticide use. Nevertheless, we believe that it is possible and is a worthwhile and environmentally-friendly goal for San Francisco.

Lessons From the Terrible North Bay Wildfires of 2017

This careful analysis of the terrible wildfires in the San Francisco Bay Area is republished with permission from MillionTrees, a website that fights to prevent unnecessary tree removal in the Bay Area.

 

Lessons learned from fires in the North Bay

Recent wildfires in the North Bay were devastating.  At least 42 people were killed by the fires and over 8,000 structures were destroyed, including homes and businesses.  We don’t want to portray that fire as anything other than a tragedy.  However, for those with a sincere interest in fire safety, there are many lessons to be learned from that fire.  If people will open their eyes and their minds to the reality of those fires, there are opportunities to reduce fire hazards revealed by those fires.

What burned?

Watching videos of the fires is the best way to answer the question, “What burned?”  Here are two videos of the fires that we found on the internet by doing a search for “videos of wildfires in Napa and Sonoma counties.”

If you weren’t watching the news during the fires, you might start by looking at these videos.  There are many more videos on the internet of those fires.

Here’s what we can see in these videos:

  • The fire front moved rapidly through native conifers and oaks as well as through grassland and chaparral. After watching hours of these videos, we did not see any eucalyptus trees on fire.
  • Many homes burned without igniting the trees and vegetation around them. If the photo was taken while the home was still burning, the vegetation is rarely engaged in the fires.  If the photo was taken after the home burned, much of the vegetation is burned as well.  In other words, the burning homes ignited the vegetation, not vice versa.
  • In videos of actively burning homes, the air is filled with burning embers. The source of those embers cannot be determined from the videos.

Nothing in these videos suggests that native vegetation is less flammable than non-native vegetation.  Nothing in these videos suggests that the vegetation is more flammable than the structures that burned. 

CalFire has identified the specific locations where four of the fires originated.  Two are in groves of oak trees and two are in grassland and chaparral.  Photos of those specific locations are available HERE.

What role did the weather play in the fire?

All sources of information about the fire reported that strong winds were the biggest factor in the rapid advance of the fire.  The wind was associated with very high temperatures and it came from the east.  This type of wind is called a Diablo Wind in Northern California.  In Southern California it is called Santa Ana Winds.  In the Mediterranean, it is called Mistral Winds.

In coastal Mediterranean climates such as California and the Mediterranean regions of France and Spain, the wind ordinarily comes off of the ocean.  Because the ocean is cooler than the land, the wind is usually a source of moisture and cooler temperatures.  During periods of high summer temperatures, the wind sometimes shifts direction and starts to blow off the hot interior, drying the vegetation and increasing temperatures.

Such winds were also the main cause of the wildfire in the Oakland/Berkeley hills in 1991Jan Null was the lead forecaster for the National Weather Service in the Bay Area in 1991.  He recently said of the 1991 fire:  “At the time a fire starts, the really relevant conditions are the wind speeds, the temperature and the humidity. Again, the humidity goes to the dryness of the fuel. The temperatures also go to the dryness of the fuels and the wind speeds go to what the spread of the fire is. If we’d had that same Oakland Hills fire without any wind, we wouldn’t be talking about it now.”

Most wildfires in California are caused by strong, dry, hot winds.  Everything burns in a wind-driven fire.  Both native and non-native vegetation burns in a wind-driven fire.  Homes in the path of a wind-driven fire are more likely to burn than the vegetation that surrounds the homes because the vegetation contains more moisture.

Why are wildfires becoming more frequent and more intense?

Wildfires are becoming more frequent and more intense all over the world because of climate change.  Temperatures are higher, drought is more frequent, strong winds are more frequent.

Wildfires in the west have become more severe because of increased temperatures and lower humidity at night.  When it doesn’t cool off at night, the trees don’t have an opportunity to regain the moisture they have lost during the high daytime temperatures.  In the past, firefighters could count on wildfires to die down at night.  Now they can’t count on colder nights to make the fires less severe. (2)  Since the fires in the North Bay started in the middle of the night and did the most damage that first night, this observation about warmer nights is particularly relevant to those fires.

Deforestation is the second greatest source of the greenhouse gases causing climate change Every healthy tree we destroy releases its stored carbon as it decomposes.  Every tree that dies of drought releases its carbon as it decomposes.  Every tree that burns in a wildfire releases its carbon as it burns.

What role did power lines play in the fire?

The investigation of the recent wildfires in the North Bay is not complete, but early indications suggest that power lines probably ignited some of the fires.  Some power poles fell over in the strong winds, causing the power lines to break and spark ignitions.  Some trees were blown into the power lines, causing them to break or spark.

California State law requires that trees be pruned at least 4 feet from the power lines.  Although PG&E says they are inspecting thousands of miles of power lines to identify potential interference with trees, these inspections are apparently not adequate.  After the fires started, PG&E claimed they had removed 236,000 “dead and dying” trees and “destroyed or pruned” 1.2 million healthy trees in 2016.  These destroyed trees contribute to climate change.

California State law also requires that power poles are capable of withstanding winds of a certain velocity.  However, power poles fell over during the recent fires when wind speeds were below that standard set by State law.

Apparently PG&E’s efforts to inspect and maintain power lines were inadequate and State laws intended to ensure the safety of power lines are not being enforced.

Did Sudden Oak Death contribute to the fire?

Sudden Oak Death (SOD) killed 5 million oak trees in California from 1994 to 2016, when that number was reported by a study.  The study also said that the SOD epidemic could not be stopped and would eventually kill all oaks in California.  More recent estimates are that 5 to 10 million oaks have been killed by SOD. (2)

SOD is caused by a pathogen that is spread by rain and wind.  We had a great deal of rain in 2016 and 2017, which has greatly increased the spread of SOD.  In the past, SOD has been mostly confined to wildlands.  Now it is found in many urban areas, including San Francisco and the East Bay.  In the most recent SOD survey done in spring 2017, new infections were found on the UC Berkeley campus, the UC arboretum, and the San Francisco Presidio. (2)

The scientist at UC Berkeley who conducts the annual survey of SOD infections reports that “A dramatic increase this year in the number of oaks, manzanita and native plants infected by the tree-killing disease known as sudden oak death likely helped spread the massive fires that raged through the North Bay…” (3)

Dead trees are more flammable than living trees because living trees contain more moisture.  In addition to more than 5 million dead oak trees in California, 102 million native conifer trees in the Sierra Nevada foothills were killed by drought, warming temperatures and native beetle infestations during the drought years. All of these trees are native to California.  This is another indication that native trees are not less flammable than living non-native trees.

The ranges of native plants and animals are changing because of climate change.  They must move to find the climate conditions to which they are adapted.  Native plant “restorations” that attempt to reintroduce plants where they existed 250 years ago, prior to the arrival of Europeans, do not take into consideration that the plants may no longer be adapted to those locations.  That’s why many “restorations” are not successful.

If you haven’t seen the Sutro Forest, you should do so soon. The plans are to destroy about 50% of the trees and most of the understory.

Native plant advocates have their heads in the sand about Sudden Oak Death.  The recently published Environmental Impact Report for San Francisco’s Sutro Forest announced UCSF’s intention to destroy about 50% of the non-native trees on Mount Sutro and replace some of them with native trees, including oaks and bays.  Bays are the vector of the pathogen causing SOD.  The EIR said NOTHING about Sudden Oak Death, nor did it acknowledge the existence of the disease in Golden Gate Park and the arboretum, less than a mile away from Mount Sutro.  What’s the point of destroying healthy trees and replacing them with trees that are likely to die in the near future?

Where to go from here?

We are not powerless against bad decisions of public utilities and the forces of nature.  There are things we can do to address these causes of wildfires in California:

  • We must address the causes of climate change. We must stop destroying healthy trees and we must plant more trees.  We must choose species of trees that have a future in the changed climate.  The trees must be adapted to current and anticipated climate conditions.  We must quit destroying trees simply because they are not native.  Non-native trees are not more flammable than native trees and many are better adapted to current climate conditions.
  • We must regulate our public utilities and demand that regulations be enforced. The Public Utilities Commission initiated an effort to improve the safety of power lines in 2007, after destructive wildfires. The utility companies have been actively dragging their feet to prevent new regulations because they would increase costs, despite the fact that they would improve safety.
  • Improved regulation of utilities should minimize the need to destroy healthy trees, by undergrounding power lines in the most high-risk areas, improving insulation of the wires, replacing wooden power poles with metal and/or concrete poles, installing sensors that identify breaks in the power lines, etc.

Demonizing non-native trees is preventing us from addressing the causes of climate change and the closely related issue of increasing frequency and intensity of wildfires.  Let’s open our eyes and our minds to the reality of wildfires in California and develop the policies that will reduce fire hazards.

Montara Chainsawed Trees: Town Hall on Nov 12, 2017

We reported recently that some people interested in going on the walk at Rancho Corral de Tierra in Montara were unable to get in. Now a Town Hall has been scheduled on Nov 12, 2017.

In response to public interest, GGNRA will be hosting a second public meeting on Sunday, November 12th from 2-3:30 pm at Farralone View Elementary School. A meeting invite with details will be sent to everyone on our email distribution list.  To stay informed about the November 12th public meeting and other park related matters in San Mateo County, please sign up for our [i.e, GGNRA’s]  “San Mateo County” mailing list here.

 

What Happened at the Montara Walk with Jacquie Speier – Trees at Rancho Corral De Tierra

Recently, we announced the news that a public walk had been planned for Oct 30, 2017 to discuss the sudden and deplorable destruction of trees at Montara’s Rancho Corral de Tierra. (We reported on that here: National Park Trees meet Chainsaws in Montara.) However, when supporters tried to sign up, they found the walk had filled up within days, maybe hours, of the announcement. Fortunately, one person did manage to go, and has sent us this report.

THEY’RE CUTTING DOWN TREES BECAUSE THEY HAVE THE MONEY – FOR NOW

Emotions ran high during a Monday mid-afternoon public hike led by a large contingent of National Park Service officials to quell community uproar over the sudden removal of healthy Monterey cypress and pines along popular trails at Rancho Corral de Tierra.

Congresswoman Jackie Speier kicked off the trailhead gathering of 30 or so nearby Montara and Moss Beach residents with sharp criticism of the Park Service’s “woefully failed” communications effort about its grasslands restoration program.

People questioned whether it was truly necessary to cut down 25 isolated trees – some 100 years old and community favorites – to preserve a rare flower called Hickman’s potentilla by replanting native grasses and wildflowers. They also asked why the Park Service did not publicly identify the trees slated for destruction or disclose its use of the herbicide Glyphosate, better known by the brand name RoundUp. California may soon require cancer warnings on Glyphosate products. [The chemical is considered “probably carcinogenic” by the World Health Organization, and an insider from the Environmental Protection Agency said, “It is essential certain that glyphosate causes cancer.”]

While the Park Service conceded it could have done a better job of communicating plans, they offered tortured answers to critical questions about the project.

Officials said it would be too difficult to identify the trees to be felled because markings could not be placed so they are visible at every angle from various directions people walk. They said the herbicide spraying schedule is unpredictable due to weather and, therefore, does not allow for advance notification or signs but that trails are closed off by staff standing guard during the spraying.

The Park Service said it contracts with outside crews for tree-cutting that must be completed under a $200,000 grant that only funds the project for three years.

It’s not clear whether the Park Service conducted an environmental analysis despite claiming they are required by the U.S. Fish & Wildlife Service to protect the potentilla at Rancho under the Endangered Species Act. If that is their rationale they are as matter of law required to conduct a public process before making significant changes that affect the landscape and recreation.

Congresswoman Speier announced she would hold a joint town hall with the GGNRA deputy superintendent to seek resolutions working together with the community. The town hall will be November 12 in Montara in the evening.

It’s important that folks try to attend because the Park Service has only agreed to stop killing trees until that meeting takes place. We’ll post more information when the meeting time and location are set. Stay tuned.
