Agenda
2001 Management Plan
• Objectives:
– Ensure public safety/property protection
– Improve health of forest
– Protect/expand native plants
– Enhance wildlife habitat
– Maintain scenic quality
– Improve public access
– Implement Management Plan
• Framework, not blueprint, for managing Reserve
3
2001 Management Plan
• Phase 1 of long-term management program
• Five types of actions:
– Hazardous tree removal
– Eucalyptus thinning
– Conversion planting
– Native plant restoration/enhancement
– Trail system improvements
• Phase 1 actions in 32 various acres of Reserve
• Annually phased work
• Adaptive management strategy

Three levels
of priorities
Actions Taken Since 2001
Priority 1 actions complete (7 of 9):
• Crestmont-Christopher, and Lower Medical
Center Way Hazardous Tree removal
• Installation of Rotary Meadow, a native plant
demonstration area on the summit
(combination of 3 Management Plan actions)
• Aldea Screen Planting
• Cleared and improved trails through the efforts
of Mount Sutro Stewards
6
Actions Taken Since 2001 (cont.)
Priority 2 actions complete (1 of 4):
• Edgewood, Surge Hazardous Tree removal
Priority 3 actions complete (3 of 7):
• Upper Medical Center Way, East Aldea and Chancellor’s Residence Hazardous Tree removal
7
Additional Actions Taken Since 2001
• Slope stabilization and native planting on hillside
slide (due to water pipe break) site above
Medical Center Way
• Tree and brush removal for construction of
Regeneration Medicine Building
• Mount Sutro Stewards’ historical trail restoration
• Non-UCSF project: SF Public Utilities
Commission pump house and pipeline project
8
How Conditions Have Changed
• Forest health has continued to decline
• Fuel load has continued to increase
• Fewer hazardous trees in a few limited
areas
• Native plant garden at summit
• Trail improvements but still incomplete
9
2001 Adaptive Management Strategy
• Demonstration projects prior to full-scale
implementation
• Eucalyptus Thinning in 2-acre Area L (primary
demonstration project)
• Eucalyptus Thinning in 0.5-acre Area P
(secondary demonstration project)
10
2001 Adaptive Management Strategy
• Conversion Planting in 7.6 total acres in
Areas B, C, D, F, J, K, N and O (summit,
south ridge and east bowl/corridor) with
variety of native plants
11
Sutro ForestGoals and Objectives
• SAFE
• HEALTHY
• AESTHETIC
• USABLE
12
SAFE
• Reduce potential for devastating wildfire
• Provide emergency response access
• Remove hazardous trees near trails, roads and structures
• Improve trailside visibility
13
HEALTHY
• Reduce competition among trees (growing space, soil water and fertility)
• Remove diseased and unhealthy trees
• Increase growing space
• Remove vines from tree trunks
14
AESTHETIC
• Maintain a forested setting
• Maintain attractive, healthy trees
• Improve visibility within forest
• Provide views beyond forest
• Privacy for neighbors
15
USABLE
• Maintain adequate path and trailside clearance
• Place logs for seating along trails and to close unauthorized trails
• Modify steep trail segments with switchbacks
• Enrich habitat and outdoor experience

Examples of Other
Eucalyptus Thinning Projects
18
Highway 1 “13 Curves”Point Reyes National Seashore
Issues:
• Fire safe access/egress/use for highway travelers
• Enhance native bird habitat
• Contain loss of native plants
• Reduce damage to riparian systems
AfterBefore

Highway 1 “13 Curves”continued
20
Prescriptions:
• Remove ground and ladder fuels
• Remove saplings under 10” in diameter
• Treat stumps with Garlon
• Remove subordinate trunks of multi-trunk trees
• Clear trunks of loose bark, debris 10’ off ground
Results:
• Very low return of understory to date
• No tree failures due to thinning
• No transfer of herbicide to adjacent trees
Camino Del CanyonNear Muir Woods National Monument
Issues:
• Fire safe access/egress for
residents
• Reinforce/enhance
defensible space
• Preserve historic tree
alignment
• Contain loss of native plants
• Prevent regrowth without
herbicides
Before
After21
Camino Del Canyoncontinued
22
Prescriptions:
• Remove ground and ladder fuels
• Remove saplings under 10” in diameter
• Raise crowns to 10’+ above ground
• Clear trunks of loose bark, debris up to 10’
• Cover stumps with black plastic, wood chips
Results:
• More open, accessible and safe forest
• Removed 60% of eucalyptus stems
• Stump kill was fully effective on covered stumps
• Understory of poison oak, blackberry returned
Dominican College
Issues:
• Fire safe emergency access/evacuation routes
• Fire hazard reduction for surrounding community
• Reduction of ignition risks
• Reduction of fire intensity/rate of spread
Prescriptions:
• Remove ground and ladder fuels
• Thin trees for equipment maintenance
• Remove saplings under 8” in diameter
• Clear trunks of loose bark, debris to 10’
• Clear debris around remaining trees
• No herbicides usedBefore 23
Dominican Collegecontinued
Results:
• Nearby fire subsequent
to treatment was easily
suppressed at site
• Flat area maintained
with small tractor
• Hillside not maintained
and remains hazardous
• No tree failures with
thinning
After

Vista Tiburon
Issues:
• Reduce fire threat to surrounding homes
• Remove or safety prune hazard trees
• Reinforce and enhance defensible space
• Preserve screening for higher residents
• Preserve privacy for residents
• Enhance habitat with native trees/shrubs
• Retain forested setting

Purposes of CEQA
• Inform governmental decision-makers and the
public about potential significant environmental
effects of proposed activities
• Identify ways to avoid or reduce significant impacts
• Prevent significant impacts by requiring feasible
mitigation measures or alternatives
