    600 native terrestrial vertebrates
  • Incorporate GAP data with ongoing conservation
    planning efforts
  • North American Bird Conservation Initiative
  • USFWS Refuges, Ecological Services, and CCP
    Planning Process

SE-GAP Deliverables
  • 2001 NLCD level land cover (20 classes)
  • 2001 GAP level land cover based on NatureServe
    Systems (135 classes)
  • Digital photo library (30,000)
  • Ancillary data sets (NHD, NED, NWI, landform)
    used in spatial modeling
  • Vertebrate database
  • Taxonomic information
  • Protection status
  • Habitat relationships
  • Textual descriptions of habitat
  • Spatial modeling criteria
  • Citations
  • 600 vertebrate species known range maps and
    distribution models (presence/absence)

Pilot Project Objectives
  • Knowledge-based Habitat Suitability Maps
  • Ranking of model parameters for habitat
    suitability by expert opinion

13
Pilot Project Objectives
  • Knowledge-based Habitat Suitability Maps
  • Ranking of model parameters for habitat
    suitability by expert opinion
  • Sensitivity Analysis
  • Determine the influence of model inputs on
    prediction areas
  • Little impact but is it critical to the
    species?
  • Big impact - assess reliability and focus on
    refinement
  • Management implications
  • Distance to water protect riparian habitat.
  • Open grassland land cover type implement fire
    management

Pilot Project Objectives
  • Knowledge-based Habitat Suitability Maps
  • Ranking of model parameters for habitat
    suitability by expert opinion
  • Sensitivity Analysis
  • Determine the influence of model inputs on
    prediction areas
  • Data-driven Habitat Suitability Maps
  • Develop habitat suitability classification with
    existing observation datasets and a variety of
    statistical approaches (CART, DOMAIN, MaxEnt,
    etc.)

Consolidating / Updating GAP Data in the
Northeastern US
  • Vertebrate Data similar approach to SE-GAP
    effort
  • Land Cover Data modified approach due to
    available data (i.e. FIA) and integration with
    other ongoing efforts
  • Stewardship Data compile and update boundary
    and GAP status for region

ANALYSES AND APPLICATIONS
  • How can we better serve GAP data for ongoing
    conservation planning efforts (i.e. Wildlife
    Action Plans, HCPs, others)?
  • Develop a web-based interactive decision support
    tool based on the functionality of the GAP
    Ecosystem Data Explorer Tool GAP regional
    datasets.

21
LAND COVER MAPPING
  • Map Ecological Systems of the Chesapeake Bay,
    Central Appalachian Region (Zones 60 and 61),
    Southern Alleghany Plateau and to complete the
    maps for West Virginia and Ohio (Zone 62 and 52).
  • Study the application of pattern recognition in
    image classification for mapping herbaceous
    Ecological Systems and anthropogenic cover types.
  • Study the application of Light Detection and
    Radar (LiDAR) data for enhancing land cover data
    with sub-canopy structural information.
  • Land cover mapping for zones 63, 64, 65, and 66
    (New England) to support the creation of a
    seamless mosaic of detailed land cover for the
    entire Eastern United States.

22
VERTREBRATE MODELING
  • Deductive modeling of vertebrate species habitat
    for Northeast (ME, NH, VT, MA, RI, CT, NY, PA,
    NJ, MD, DE, and OH).
  • This effort in combination with the models for
    the Southeastern Region will provide a seamless
    dataset for the Eastern United States.
  • Inductive habitat suitability modeling for
    priority bird species in selected Bird
    Conservation Regions of the Eastern United States.

23
LAND STEWARDSHIP
  • Analyze the distribution and pattern of
    conservation lands throughout the Southeastern
    U.S.
  • Develop prototype analyses and applications for
    land trusts whose primary interests include
    natural resource conservation.
