UCSF has published its initial study for the Environmental Impact Report (EIR) on the new 2017 Plan for Sutro Forest. This “Notice of Preparation and Initial Study” outlines the areas the EIR will cover. Comments on the Initial Study can be sent any time before March 8th, 2017. They are also holding the EIR scoping meeting on February 23rd, 2017. (Thursday, Feb 23 2017 at 06:30 pm, Millberry Union, 500 Parnassus Avenue, San Francisco, CA 94122)

The NOPIS repeats some of Plan description of the forest, which it characterizes as being in poor health.
TOO MANY TREES?
In the 2013 EIR, UCSF estimated there were 45,000 trees in the Reserve. It intended to cut down 60% of them, or 27,000 trees. That would have left 18,000 trees. The new Plan has sharply reduced its tree population estimates: It now says there are only 10,000 live trees (and 3,500 dead or dying ones). Since it is impossible that 35,000 trees were removed in the interim without our knowledge, we’re going to assume that there was a pretty substantial mistake somewhere. Given that the new estimate is about one-third of the old one, we can also assume a large margin of error on these estimates.
Remarkably, the Plan (and the NOPIS) still says there are “too many blue gum eucalyptus trees” in the Reserve. This is even though this estimated population is less than a quarter of the original estimate – and about half the trees they expected to retain after implementing the controversial 2014 EIR and Plan. The new Plan is for 75-100 trees per acre. The actual forest will also shrink: They plan to remove all large trees on 14 acres of “defensible space” near buildings; expand the Native Plant area from 2 acres to 5 acres; create access roads for machinery, and broaden trails. This means the forest size would be reduced from 61 acres to perhaps 40 acres or less. The number of trees then would drop from 10,000 (if their current estimate is right) to around 3-4,000 trees – with more than 6,000 healthy trees being removed. They plan to retain only 2-3 snags per acre, so that would mean that 3,300 dead or dying trees would also be removed.
It sounds like any number of trees that makes Sutro Forest look like a forest are “too many.” With the new emphasis on native plants in the revised Plan, this is clearly an effort to clear spaces to change the character of the forest to a patchwork of native plant gardens punctuated by stands of trees – a forest in name only.
NATURAL FOREST, NOT DISEASED AND DYING
The NOPIS (and the Plan) assert the forest will not recover on its own, and references “forest pathogens.” No details are provided. A living forest is expected to have pathogens – otherwise there would be no biosphere or ecosystem. This is a “natural forest” not a diseased and dying one, as alleged by Craig Dawson in his alarmist 2014 article. The reaction of some experts to that article:
- “The diseases and insects mentioned in the Sutro report could be found in any forest…” (from a certified arborist and plant pathologist)
- “The description of common conditions of eucalypt trees on the part of Mr Dawson’s piece seems to me solid as such—a description—but unconvincing as an argument that pretends to show some state of pathological emergency in Sutro…” (from an environmental science professor)
- “This is amateur plant pathology at its best….” (from an urban forester)
- “…faith-based botany…” (from an urban forester)
- “This is certainly not the first time I have seen someone want to use a disease threat as a roundabout way to get some politically inconvenient trees removed.” (from an academic plant pathologist)
The percentage of dead trees is high – but not exceptionally so. Dead trees have a high ecological and habitat value – insects feed on them, in turn providing food to many kinds of birds and some animals. The weakened wood provides easily excavated cavities where birds can nest. As a result, forests are often managed for deadwood for biodiversity and ecological reasons. In one such example, a pamphlet on Managing Deadwood in Forests and Woodlands, uses a percentage of 0-10% of the stems dead as low ecological value, and >20% as “high” ecological value. Thus, 25% of the stems (trunks) being dead is not a sign of disaster. Especially since, with a large margin of error, the actual percentage could be much lower.
The forest has been given no opportunity to recover on its own. Whenever saplings appear, they are torn out, as are all the other natural plants of forest by people biased against “invasive” plants. This picture, from March 2013, shows healthy saplings in the “gash” – the place where the forest was cut down for a water-pipe replacement. It is specifically mentioned in the Plan as an area where regeneration is not taking place. The saplings were ripped out soon after this picture was taken.
Forests create their own ecosystem and environment. Trees in a forest have interconnected root systems and they also protect and support one another above ground. Drastically reducing tree density damages the trees that remain and makes them more vulnerable to being blown down in the wind. The removal of over a thousand trees and large swathes of the blackberry understory has necessarily weakened the forest’s ability to retain moisture. This would have rendered it more vulnerable in the previous drought years.
This vulnerability will be worsened by the next element of the Plan: ‘Establishing a mosaic of trees, shrubs and ground cover… with gaps in the canopy…” This would be a thinned and therefore drier and more windy forest. Especially given shallow soils and high winds, the weakening of the intergrafted root network is bound to destabilize the forest, and possibly the hillsides as well.
“Manage vegetation only around the trails…” says the Plan. The glitch is that the trails are now so extensive that practically any area qualifies: see the map below, taken from the NOPIS (published here as a fair use for purposes of discussion and critique).
A “group selection area” is one where all the trees in the selected area will be cut down.
HERE COMES A LOGGING OPERATION
UCSF plans lots of heavy machinery for the forest, any time from August until end-January – and starting this year :
- Handsaws, Polesaws, Chainsaws
- D-6 tractors or similar
- Excavators, Backhoes, Loaders, Masticators, Feller bunchers,
- Pick-up trucks, skidders, forwarders, water trucks,
- Log trucks, chip vans, chippers, tub grinders, stump grinders, and cranes.
They will also build temporary access roads (which will require more tree removal) and widen existing trails by 3-4 feet to “accommodate equipment.”
They’ll establish a staging area for chips and logs, and truck this to some destination outside San Francisco.
The only positive is that NO herbicides will be used.
The NOPIS has listed a large number of potential impact categories – as it should. This project is going to be very destructive.
- Aesthetics: Potential adverse effect on a scenic vista, substantially degrade the existing visual character of the site, and exceed UCSF’s long-range development plan’s wind parameters.
- Agriculture and forestry resources: Converting forest land to non-forest use.
- Air quality: Conflicts with applicable air quality plan, contributes to pollution, exceeds LRDP standards for increased hazard due to toxic air contamination.
- Biological resources: Potentially impacts special status species, riparian habitat, migratory species, tree preservation.
- Cultural and tribal resources: Possible impacts on tribal cultural resources
- Geology and soils: Could cause landslides, unstable geological unit, substantial erosion
- Greenhouse gas emissions: These would increase.
- Hazards and hazardous materials: Potential impact owing to possible fuel spills, asbestos release from rock outcrops, within 0.25 miles of several schools, possible increased fire risk through increased forest dryness.
- Hydrology and water quality: substantially altered drainage pattern, create additional water run-off.
- Noise: Permanently increase ambient noise, substantially increase temporary noise.
- Public Services: Impact the need for fire protection, police protection.
- Recreation. The project could interfere with the recreational value of the Forest.
- Transportation and traffic: Substantially increase traffic hazards (due to the heavy machinery described earlier on the narrow roads of the forest), inadequate emergency access, exceed LRDP standard of significance for causing conflict among autos, bicycles, pedestrians, and transit vehicles.
- Utilities and Service systems: May need a lot of extra water if they decide to irrigate new plantings. They don’t expect to impact wastewater, or the huge amount of solid waste generated by felling and chipping the trees.
The NOPIS also concludes that the Plan has potentially significant cumulative effects on the environment, affecting people as well as plants and animals.
