7.  Edge effect 300 m  All forest types, water, wetlands, shrublands are non-hostile  Minimum viable population (MVP) of 50 pairs  MVP in contiguous or aggregated patches  Minimum patch size equals area required to support 1 pair  300 m buffer from hostile habitats  Incorporate all non-hostile when identifying “forest core”  Minimum suitable forested wetland core supports 50 pairs  Contiguous or aggregated patches w/in 500 or 1,000 ha landscapes  Minimum patch size = 3 ha for high density birds and 8 ha for low density birds AssumptionsParameters Biological Model Relating Birds to their Habitat

8. Core Habitat Core needed to support 50 breeding pairs –150 ha (species w/ 3 ha territories) –400 ha (species w/ 8 ha territories) Contiguous Habitat: Total forest patch size (core & buffer) –~ 500 ha (assumes ~10% addition for shape) –~1,000 ha Habitat Requirements

9. Contiguous Non-contiguous –Acceptable aggregations 150 ha of core within 500 ha landscape with a minimum core patch size of 3 ha 400 ha of core within 1,000 ha landscape with a minimum core patch size of 8 ha Habitat Requirements

24. Questions and Challenges Step-down - Are the BBS derived population estimates accurate? - Are the percentage of populations within a BCR correct? - How do I incorporate the C-Plan objectives (increase by 10%, increase by 50%, or double population estimate)? Step-up - Are the population estimates derived from “suitability” models accurate? - Are the (local) density estimates valid? - How do I distribute a species population among habitats (upland vs. bottomlands)? - Should I use a population estimate derived from the 1990s as the basis of my habitat objectives?

25. Next Steps….. 1. Resolve the outstanding questions and challenges. 2. Pursue the development of spatially-explicit habitat objectives and a decision support model to guide restoration and management. 3. Incorporate Forest Inventory and Analysis (FIA) data into the biological models, such that models speak to both, quantitative and qualitative aspects of bird biology.
