Linking Habitats Supply and Populations Why, What, When, Where and How?
Why? • Ease communication • Articulate habitat supply objectives (as protection, maintenance, enhancement, restoration or recovery targets) • Compare relative conservation merits of land use scenarios (either management direction or zonation or both) • Describe trends in space and through time
What? • Persistence / viability / extinction probabilities • RNOV thresholds • Densities translated into animal numbers • Surrogates (e.g. functional territories) • For each: over space and through time
When and Where? • During Land Use Planning • During SAR Recovery Planning • During Environmental Assessment • During Cumulative Effects Analysis • When not? Situations where no relatively simple linking mechanism
How? • Density assignments • Habitat-based PVA (and other voodoo) • Identification of Trophic Relationships • Definitions of Populations • Investigations of: Carrying Capacity, Density Dependence, Stochasticity, Proximate and Ultimate Limiting Factors, Relationships with all kinds of Landscape Metrics……
