  1. Ecological condition of national parks Theobald activities 8 March 2007

  2. Objective #1 Landscape-level indicators and ecologically-relevant boundaries • Engaged in discussion with ROMN through ROMO/FLFO WCA about indicators • Follow up to needs assessment with ROMN group • Landscape dynamics • Land use change • Fragmentation/connectivity indices • Modification of land cover and fragmentation from land use dynamics  SYNERGISTIC (w/Hansen, Goetz, Melton) • ?Opportunity to provide “primer” on relevant landscape metrics • ?Recommendation of “core” national-level indicators

  3. Preliminary selected indicators for ROMO/FLFO WCA I. Landscape condition • Vegetation composition, structure & soils • Landscape dynamics (broader land use changes) II. Biotic condition • freshwater, wetland communities (watershed-scale) • Beaver dams, habitat suitability model III. Chemical & physical characteristics • Wet & dry deposition (N) • Water chemistry IV. Ecological processes • Invasive plants • Invasive aquatic biota (lower priority) V. Hydrology & geomorphology • Surface water dynamics VI. Natural disturbance regimes • Fire regime (wildfire, beetle outbreak) • Avalanche paths VII. Social-ecological systems • Visitor use (accessibility) • Institutional (integrative complexity)

  4. Objective #2 Integration of RS products with NPS DSS • US Census data, accessibility • SYNERGISTIC activity with TOPS

  5. Objective #3 Analyses and forecasts • Development of metrics • Land cover and use, SERGoM model • Links to % impervious surface, % canopy, miles of roads, invasives, etc. (SYNERGISTIC w/Goetz) • Biodiversity & habitat models (FunConn graph theory) • Trends and forecasts • Ecoregional context of parks (graphs) • Link housing trends to develop forecasts of other metrics

  6. Objective #4 Integration into NPS DSS • Spatially explicit models allow relative indices at decision-relevant scales • Development of ArcGIS ModelBuilder tools • worked datasets • worked examples • user manuals • training sessions

  7. n x n Matrix Habitat Modeling Toolset Land use/cover Create Habitat Quality Define Functional Patches Land cover w/ disturbance Landscape Network.mdb* Build Landscape Network Resource quality reclass table Functional Patches Habitat Quality Patch structure reclass table Land cover w/ disturbance Minimum patch size Edges Disturbance reclass table Cost surface (optional) Patch/foraging radius Nodes Resource quality threshold Permeability reclass table Linkages Core habitat percentage Minimum patch size Aggregation factor Corridors Resource quality threshold Aggregation factor Resource quality threshold Resource quality threshold *The landscape network resulting from the Habitat Modeling processes can be analyzed in the Landscape Networks/Analysis Toolset.
