Selecting Focal Species for a Comprehensive Ecosystem Umbrella Existing Selection Approaches • • • • • • • • • • • Vulnerable Species Endemic Species Flagship Species Phylogenetically Distinct/Evolutionarily Important EDGE Taxonomic Groupings Indicator Species Umbrella Species Keystone Species Focal Species Landscape Species Selecting Landscape Species 5 criteria area for selecting vulnerability landscape species socio-economic significance functionality heterogeneity Choosing a Focal Species Suite to Create a Complete Conservation Umbrella Goals: • Conserve sufficient quantity and quality of all major habitat types to support ecologically functional populations of all native species present in the planning area. • Implement mitigation strategies that effectively reduce the impact of all activities that significantly threaten the persistence of any native species to levels that insure a high likelihood of persistence for the next 100 years. • Ensure the continuation of all natural ecosystem processes (either through natural occurrence or simulation by prescription) that are necessary for the long-term persistence of all native species within their natural range of variability of abundance. • Respect the importance of wildlife to local economies and culture, and implementing strategies to maximize positive, and minimizes negative, effects of wildlife on these economies while preserving cultural values.
