Sierra Club must STOP advocating for deforestation and pesticide use in San Francisco Bay Area
We are environmentalists who ask the Sierra Club to quit advocating for the destruction of the urban forest and the use of pesticides in the San Francisco Bay Area. We also ask that the Sierra Club withdraw its suit against FEMA, which demands the destruction of 100% of all “non-native” trees (eucalyptus, Monterey pine, acacia). If you are signing this petition and you are a present or former member of the Sierra Club, please mention it in your comments.
Over the past 15 years, tens of thousands of trees have been destroyed on public lands in the San Francisco Bay Area. Now hundreds of thousands of trees in the East Bay are in jeopardy of being destroyed by a FEMA grant to three public land managers. The Bay Area Chapter of the Sierra Club has actively supported all of these projects and now it has sued FEMA to demand the destruction of 100% of all “non-native” trees.
These projects have already used hundreds of gallons of herbicide to prevent the trees from resprouting and to kill the weeds that grow when the shade of the canopy is destroyed. Now, the FEMA project intends to use thousands of gallons of herbicide for the same purpose. These herbicides (glyphosate, triclopyr, imazapyr) are known to be harmful to wildlife, pets, and humans.
This environmental disaster will release tons of carbon into the atmosphere, thereby contributing to climate change. It will destroy valuable habitat for wildlife, introduce poisons into our watershed, cause erosion, and eliminate our windbreak. We call on the national leadership of the Sierra Club to prevent the active participation of the Bay Area Chapter of the Sierra Club in this environmental disaster.
Why is this important?
The San Francisco Bay Area was virtually treeless prior to the arrival of Europeans. The landscape was predominantly grassland, scrub, and chaparral. Trees grew only in ravines where they were sheltered from the wind and water was funneled to them. The trees that were brought from other areas of California and from other countries were chosen because they are the species that are best adapted to our local conditions. John Muir, the Founder of the Sierra Club, also planted these tree species around his home in Martinez and was as fond of those trees as many of us are still today.
The Sierra Club has now turned its back on this cosmopolitan view of nature in favor of returning our landscape to the pre-settlement landscape of grassland, scrub, and chaparral. This approach has led to the destruction of tens of thousands of trees and the use of herbicides to prevent them from resprouting.
In the East Bay, native plant advocates have also falsely claimed that “non-native” trees are more flammable than native plants. Although fire hazard reduction was the stated purpose of the FEMA grants, fire hazards will be increased by the clear-cuts of our urban forest for the following reasons:
• Tons of dead, dry wood chips will be scattered on the ground to a depth of 24 inches.
• The fog drip which is condensed by the tall trees moistens the ground and will be lost when the canopy is destroyed. The ground vegetation will therefore be drier and more likely to ignite.
• The tall trees provide a windbreak which has been demonstrated repeatedly to be capable of stopping a wind-driven fire, which is typical of California wildfires.
• The project does not intend to plant any replacement plants or trees. Therefore, the most likely colonizers of the bare ground are annual grasses which ignite easily during the dry season and in which most fires in California start and spread.
Many empirical studies document the rich biodiversity of our urban forest today. Bees, hummingbirds, and monarch butterflies require eucalyptus trees during the winter months when there are few other sources of nectar. Raptors nest in our tall “non-native” trees and an empirical study finds that their nesting success is greater in those trees than in native trees.
In short, the Bay Area Chapter of the Sierra Club is promoting an environmental disaster that is adamantly opposed by tens of thousands of people. FEMA received over 13,000 public comments on its draft Environmental Impact Statement, over 90% in opposition to this project, according to FEMA’s own estimate. The signers of this petition are also opposed to this project as presently described by FEMA grant applications and its Environmental Impact Statement.
Environmentalists in the San Francisco Bay Area have been denied due process by the local chapter of the Sierra Club. The Bay Area Chapter has blocked every effort to communicate with them: they ignore our emails, block our comments on their blog, refuse our letters to the editor of their newsletter, and do not answer our phone calls. We believe that the national leadership has an obligation to consider our complaint because the actions of the local chapter are inconsistent with the mission of the Sierra Club. The local chapter is actively contributing to climate change and endorsing the use of toxic pesticides in our environment.
