Habitats provide services Habitat for fisheriesRecreational opportunitiesStorm protection

Halpern et al 2008 Risk to habitat structure and function

Scenarios Services Habitat Risk

Questions the model can answer Which habitats are most at risk and where? What types of management options may be useful for reducing risk? Where may human activities create trade-offs among environmental services by posing risk high enough to compromise habitat structure and function?

Calculating Risk Strategies for reducing risk EXPOSURE (exogenous: management, intensity, timing etc) Consequence (endogenous: regeneration, connectivity etc) HIGH RISK LOW RISK
