Recap of TAC Meeting #1

  • Mount Sutro Open Space Reserve Management Planning Process
  • Process Timeline
  • TAC Organizing Framework
  • Management Plan Goals and Objectives: Defining Success
  • Reserve and Ecosystem Health
  • Visual Design and Aesthetics
  • Public Safety
  • Public Access
  • Key assumptions of the plan include:

‒ Improves safety of the Reserve and protects lives and structures ‒ Addresses hazard reduction and promotes a sustainable ecosystem ‒ Includes a replanting strategy to promote biodiversity ‒ Utilizes a phased-in approach

UCSF Policies in the Reserve

  • Top priority is safety of people and structures
  • No herbicides used in the Reserve
  • Avoid unnecessary tree work in the Reserve during bird-nesting

season (March to August)

  • Commitment to transparency and community planning principles
  • Maintain and encourage public access to trail network. UCSF has

partnered with the non-profit Sutro Stewards who build and maintain trail system using volunteers

  • Preserve the beauty of the Reserve and maintain this novel

ecosystem as a public resource

Definitions: Invasive Species

  • California Invasive Plant

Council (www.cal-ipc.org/)*

  • Blue gum eucalyptus is listed

as having “limited” invasive potential

  • Management plan will focus
  • n species having “high” or

“moderate” invasive potential

  • Management plan will include

regeneration of blue gum canopy

Mount Sutro Management Plan Overview

Existing condition

  • Plant
  • Remnant native
  • Planted
  • Arrived from elsewhere
  • Birds
  • Approx. 75 species

1A: Increase biodiversity

10 TAC Meeting April 28, 2016

Tactics

  • Maintain existing remnant

native areas

  • Diversify forest composition

and structure through planting

  • Control competitive vegetation
  • Establish baselines for

vegetation and wildlife

  • Monitor bird presence and

populations

SLIDE 11

Mount Sutro Management Plan Overview

11 TAC Meeting April 28, 2016

1B: Promote native vegetation

  • Locate and inventory patches of native vegetation
  • Identify opportunities to establish native vegetation in new location

(e.g. riparian along Woodland Creek)

  • Establish specific goals for conservation, including species,

environmental requirements, management of competing vegetation

slide-12
SLIDE 12

Mount Sutro Management Plan Overview

Existing condition

  • Do not believe blue gum is

being recruited into the canopy

  • Small diameter blue gums are

numerous, but consistently in poorer condition than large diameter

  • Species shade intolerant
  • Gaps colonized by vines and
  • ther ground cover plants

1C: Improve Plant Regeneration/Recruitment

12 TAC Meeting April 28, 2016

slide-13
SLIDE 13

Mount Sutro Management Plan Overview

  • Identify silvicultural methods

(species, plot size, plant size, spacing, etc.)

  • Control competing ground

level vegetation

  • Assess the viability of

providing irrigation 1C: Improve Plant Regeneration/Recruitment

13 TAC Meeting April 28, 2016

Tactics

  • Regenerating blue gum

involves planting new trees

  • Expand tree species beyond

blue gum such as….

  • Other eucalyptus
  • Monterey pine
  • Monterey cypress
  • Coast redwood
  • Coast live oak
  • Willow
slide-14
SLIDE 14

Mount Sutro Management Plan Overview

  • Diversify tree species beyond

blue gum

  • Thin existing stands and

control competing vegetation to reduce competition for water (location and extent of thinning to be determined)

  • Focus tree work on blue gum

in winter months when beetles are not active 1D: Manage Insect and Disease Pressure

Mount Sutro Management Plan Overview

Elements

  • Species composition and

vegetation type

  • Tree crown/age/height class
  • Coarse woody debris
  • Gaps/patches in canopy

1E: Improve Structural Diversity Tactics

  • Expand number of species for

all types of vegetation

  • Control vines and competing

vegetation

  • Plant and nurture desirable

vegetation

  • Balance coarse woody debris
  • vs. fire management

Mount Sutro Management Plan Overview

Lessons from TAC meeting #1

  • “Forest” experience
  • Vegetation structure a mosaic of trees,

shrubs and ground cover

  • Gaps in canopy leading to sun and shade
  • Visible tree trunks
  • Far views: ocean, GGP
  • Shelter from wind
  • Wildlife
  • Focus on locations that are physically and

visually accessible
