Community Visioning • Spatial understanding • Setting goals • Exposing tradeoffs • Weighting multiple criteria • Examining alternative futures http://placeways.com/
Landscape Assessment • Resource quality • Threats • Costs • Opportunities & Constraints
Method An Example: Landscape analysis for mountain lions in the SF Bay region (Bren class project) How does connectivity affect the populations of Puma concolor in the Southern half of the Bay Area?
Landscape process modeling • Tools for modeling landscape processes • Agent-based models (e.g., HEXSIM) • Population models (e.g., RAMAS) • Ecosystem models (e.g. STELLA) • Landscape models (e.g., LANDIS) http://www.naturecanada.ca/media/ images/ord%27s-kangaroo-rat3.jpg
Modeling ecosystem services • watershed processes • carbon • resource production • pollination services • cultural values
Conservation strategies and scenarios • hotspot analysis • conservation portfolio design • investment prioritization • tradeoff analysis Site scores for protecting underrepresented wildlife habitat types, accounting for land cost and projected housing development in the Sierra Nevada region. (Davis et al. Ecology and Society 2006)
Tools for evaluating and mapping conservation priorities http://www.bayarealands.org/ for a good example of regional conservation planning using Marxan
Barriers to Tool Adoption • “Conservation is opportunistic, not rational.” • “The data don’t exist.” • “I don’t trust computers.” • “There are a zillion possible solutions.” • “I’m bored.” http://www.csmonitor.com/USA/Politics/2009/0904/
