Habitat Elements vs. Species Needs Importance Vegetation Structure Community Composition Habitat Generalist Habitat Specialist
Selecting Habitat Types • Identify Broad Habitat Types (e.g. coniferous forest, riparian, grassland steppe, etc.) • Subdivide by important topographical classes (lowland, alpine, etc) • Include specialty habitats (e.g. whitebark pine, cliff faces, standing burnt forest)
Choosing Focal Species • Start With: • Need large areas to survive and persist • Are sensitive to human threats or activitiesand optionally: • Are keystone species-species whose loss would significantly alter the ecosystem Add: • Species as close to target as possible • Do not overlap habitat requirements with previous species Large Area Requirements Sensitive to Threats Keystone Species
Landscape Species Approach human landscape (people’s activities) biological landscape (species’ requirements) intersections define the conservation landscape identify Priorities direct and focus interventions
Goal: To conserve and restore all major wildlife habitat types and their component species with emphasis on ungulate winter range, riparian ecosystems, and linkages between mountain chains and mountain valleys. Conservation Target: Maintain viable meta-populations of Columbia Spotted Frog Direct threat (stress): Predation and competition Direct threat (stress): Mortality Direct threat (stress): Habitat loss Source: Disease??? Source: Loss of floodplain pools due to river regulation by dams Source: Loss of beaver Source: Dewatering from irrigation, loss of beaver Source: Historical non-native fish introductions Intervention: Reduce spreading through education Indirect threat: Management emphasis on sport fishery Indirect threat: Inadequate information on breeding sites Indirect threat: Local and regional environmental contamination Intervention: Beaver restoration Intervention: Lease water rights for conservation Intervention: Remove nonnative fish Intervention: Elevate importance of amphibians and their mgmt Intervention: Inventory for breeding sites in MVPU Intervention: Mitigate contamination around breeding sites Conceptual models

Setting priorities • Species Richness • Connectivity Hotspots • Addressing Key Threats
Priority Areas for Conserving Biodiversity • Papoose Creek to Raynold’s Pass • Sagebrush Steppe • Norris Hill to North Meadow Creek • Jack Creek Drainage • Madison Willow Flats
Priority Areas for Wildlife Connectivity • Wolf Creek to Raynold’s Pass • Norris Hill to North Meadow Creek • Central Valley • Major Drainages and foothills • Virginia City Hill
Priorities Based on Threats • Protect and restore aquatic habitats that support fish and amphibians. • Restore natural fire patterns to restore fire-dependent habitats and fire-dependent species. • Protect and restore sagebrush and native grassland habitats. • Reduce the impact of subdivision development on wildlife. • Mitigate the impact of roads through improved design through travel corridors.

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.
Complete Conservation Requires Multiple Umbrellas Threats Habitat Processes Area • Complete Communities • - all native species in natural abundance • Complete Ecosystem Function • Human Values
Hierarchy of Conservation Needs Public values that support conservation Social Acceptance Allow or simulate natural processes to sustain natural habitat heterogeneity Ecological Processes Security from direct and indirect threats that threaten the survival or natural abundance of individuals or populations Security Habitat Availability of appropriate habitat types in sufficient quantity and quality to support individuals and populations Sufficient area to support individuals and populations at ecologically functional levels Area
