Native Ecosystem Restoration

Goal:  Restore native plant and animal habitat based on sound
science and adaptive management.

Background:  Fundamental understanding of the ecology and
population biology of native plant and animal species is key to
determining best management strategies for ecological restoration.
 We conduct comprehensive assessments of habitat requirements
and identify measures required for maintenance or restoration of
habitat.  We employ a variety of conservation management
techniques (mowing, burning, grazing, etc.) to control invasive
non-native plant species and to encourage healthy native
populations.  For example, at Edgewood County Park and Natural
Preserve (San Mateo County, CA), we initiated a collaborative
effort to control invasive Italian ryegrass (
Lolium multiflorum) using
mowing before seed heads have ripened, but after native plants
have had a chance to go to seed.  In another collaborative effort at
Coyote Ridge (Santa Clara County, CA), we are controlling barb
goat grass (
Aegilops triuncialis) by burning, also before seed
heads ripen.

Elements of Restoration:
  • Restoration need assessment:  determine causes of
    degradation, current habitat condition, and requirements for
    habitat restoration.
  • Restoration planning:  plan for practical, cost-effective
    restoration
  • Site protection:  limit human disturbance and
    moderate/eliminate processes causing degradation
  • Habitat enhancement: improve/rehabilitate habitat quality
    through strategic management activities
  • Invasive species control: reduce or eliminate undesirable
    organisms by hand removal, burning, mowing, grazing,
    biological controls, etc.
  • Native population enhancement/reintroduction :  transport,
    plant, or cultivate native populations
  • Adaptive management:  implement site-specific
    management plans, with periodic review of success
  • Education and outreach:  develop general and site-specific
    resources (curriculum, web, brochures, presentations, and
    signage) for education and interpretation
Benefits
  • Conservation of native biodiversity
  • Sound scientific basis for cost-effective restoration
  • Compliance with government regulations
  • Mitigation of human impacts
