Presentation Transcript

  1. Gap Analysis Vermont and New Hampshire

  2. The Process • Land cover mapping • Predicted vertebrate distribution • Stewardship lands • Analysis of gaps

  3. VT-NH GAP has predictive habitat models and maps for 306 terrestrial vertebrates Species Richness 202 birds 59 mammals 23 amphibians 22 reptiles

  4. Land cover mapping TM Imagery, 1992-93; Summer and fall scenes; Supervised classification; Details www.snr.uvm/sal

  5. Land cover mapping Aerial videography used to collect training and validation data

  6. Land cover mapping

  7. Land cover mapping

  8. Land cover mapping

  9. Predicted vertebrate distribution

  10. Predicted vertebrate distribution 1. Delineate range of each species by biophysical regions

  11. Predicted vertebrate distribution 2. Intersect with suitable habitat types from land- cover map

  12. Predicted vertebrate distribution Example for blackpoll warbler: forested land cover within selected regions

  13. Predicted vertebrate distribution 4. Modify with elevational data to produce map of predicted distribution

  14. Two-lined Salamander Gray Jay S. Flying Squirrel • Predicted vertebrate distribution

  15. Predicted vertebrate richness

  16. Stewardship lands

  17. Stewardship lands

  18. VT-NH Gap Analysis for Northern Harrier Green = predicted habitat Salmon = protected lands Red = overlap Result: only 6.7% of habitat in NH is on protected land; 11% in VT.

  19. Analysis of gaps Tabular data for each vertebrate showing acres of habitat by ownership and protection category

  20. Human settlement Vertebrate richness

  21. Analysis of gaps 23 Threatened and Endangered species

  22. VT-NH Gap Analysis: The Bottom Line Vertebrate Richness Protected Lands

  23. Vermont Biodiversity Project Objective: To design and map a system of conservation areas that protects the full diversity of landscapes, natural communities, and species.

  24. Richness Atlas data and Gap Analysis predictions

  25. Landscape • Diversity Units • (LDU) • Bedrock • Surficial • Elevation • Landform Landform: Lower slideslope Surficial material: Till Bedrock: Granite Elevation zone: 1700-2500

  26. Representativeness Objective analysis of landscape features

  27. Representative Landscapes of Vermont • 21 % of area of state • 89 % of landscape • richness • 95 % landscape • similarity

  28. VT-NH Gap Analysis Vertebrate Richness Landscape Diversity

  29. LDUs = 1408 Vertebrates = 292 494 265

  30. 20% of state: 7 5 8 2 6 • 88% of LDUs • 97% of vertebrates 1 4 9 3 10

  31. Heritage Program Elements of Occurrence “EORs” • 6349 EORs • 16% on status 1 & 2 • stewardship lands

  32. EORs = 4958 Vertebrates = 292 325 243

  33. 10% of state: 7 6 2 3 • 19% of EORs • 97% of vertebrates 8 20% of state: 1 9 • 24% of EORs • 97% of vertebrates 10 4 5
