What Is GAP?
  • A gap is the lack of representation or
    under-representation of an element of
    biodiversity (plant community or animal species)
    in an area intended for its long term
    maintenance.
  • Keep Common Species Common

4
Mission Statement
To promote conservation of biodiversity through
information... by providing conservation
assessments of natural communities and native
species, and to facilitate the application of
this information to land management.

SWReGAP Statistics
  • Project area 530,415 sq mi (339,465,600 acres)
  • 93 of the size of Alaska
  • BLM lands 31 of area
  • USFS lands 14 of area
  • State lands 7 of area
  • Tribal lands 9 of area

7
Gap Objectives
  • Map the distributions of natural communities.
  • Map predicted habitat of native animal species.
  • Map the degree of management for biodiversity
    maintenance of land tracts and water bodies
    focusing on intent.
  • Analyze the representation of biotic elements in
    the conservation network to identify gaps in
    long-term security.
  • Provide this information to the public and those
    entities charged with land use research, policy,
    planning, and management.

Predictor Data Sets Landsat ETM Imagery (MRLC
data set)
  • 85 ETM scenes for three seasons Spring, Summer
    and Fall (1999-2001)
  • Web-based tool for image standardization
  • Mapping zone mosaics

9
Training Data Collection
  • Region totals
  • 46,000 ground based ocular surveys
  • 30,000 existing databases
  • 17,000 remote sources interpretation
  • Ground-based
  • Opportunistic sampling
  • Sufficient data to assign NVC Alliance or
    Ecological System
  • Other sources
  • Ecological System label only

Overall Validation (sum of the matrices)
  • Combined error matrices for all mapping zones

15
Vertebrate Habitat Modeling and Mapping
  • Modeling habitat of vertebrate species that
    reside, breed, or use habitat in the five-state
    region for a substantial portion of their life
    history.
  • Not modeling habitat quality or species abundance

Stewardship
  • Categorizes lands
  • Public land ownership and voluntarily provided
    private conservation lands.
  • According to four levels of commitment to
    biodiversity maintenance.
  • Based on expressed long-term intent.

32
Stewardship
  • GAP Management Categories
  • Status 1 Highest level of management intent for
    biodiversity, e.g., Research Natural Areas.
  • Status 2 High level of intent but allows some
    use, e.g., Wilderness Areas that allow grazing.
  • Status 3 Intent to conserve special features or
    endangered species in context of human use, i.e.,
    public multiple use lands.
  • Status 4 No known intent to maintain
    biodiversity.

33
2 Main Products
  • SWReGAP Stewardship Data Layer
  • Develop a digital map depicting land ownership
    boundaries internal management areas combined
    with attributes of entities responsible for
    management
  • SWReGAP Conservation Status Data Layer
  • Attribute individual land units with GAP
    management status categories for purpose of
    describing biodiversity conservation and
    identification of potential gaps

Management Plans
  • Collected over 300 plans for the entire region
  • USFS Forest Plans and Amendments
  • BLM Resource Management Plans, Record of
    Decision
  • DoD Integrated Natural Resource Management
    Plans
  • NPS General Management
  • Plans/Statement of Management
  • If No Plan is Available, Conducted Interviews

Analyses
  • Intersect habitat and land cover distributions
    with stewardship
  • Create tables of representation for each element.
  • Compare ownership/managing entities to
    biodiversity management status
  • Compare Land Cover types and habitat to
    Stewardship
