The document discusses climate change vulnerability assessments for conservation. It defines vulnerability as the extent a species or ecosystem is susceptible to harm from climate impacts. Vulnerability assessments can help prioritize management actions, develop adaptation strategies, and efficiently allocate resources, but do not make conservation decisions. Key steps include determining objectives, gathering data, assessing vulnerability components, and applying results to adaptation planning. Approaches include modeling, indices, and expert elicitation. Results can help prioritize vulnerable species/systems and design management strategies to reduce sensitivity, exposure, and enhance resilience.

- 9. Using Vulnerability AssessmentResults Help prioritize species and systems • Address most vulnerable? Least? • Base on ecological/economic importance? Help design management strategies • Reduce sensitivity • Reduce exposure • Enhance adaptive capacity Help allocate resources efficiently • Set research priorities? • Consider triage?
- 10. Potential Strategies Promote connectivity: •Are you connecting the “right” habitats? Will target species/systems actually move? Reduce other stressors: • Do existing stressors increase vulnerability to climate change? Does climate change exacerbate other stressors? Enhance “resilience”: • Resilience “of what” “to what”?
- 11. Other Adaptation Questions Whatif you can’t reduce vulnerability? • Do we still do what we are already doing to try to “buy time”? • Do you decide to “let nature take its course”? • Do you actively facilitate a transition to some new state? • Should we change our conservation goals?
Editor's Notes
- #4 In the context of fish and wildlife conservation, vulnerability to climate change refers to the extent to which a species, habitat, or ecosystem is susceptible to harm from climate change impacts. It can be considered a relative concept, where you have some species or systems that are more vulnerable than others (and you may even have some that are not vulnerable at all but perhaps even benefit from climate change) – this is the “what” question.You can also be more specific as to why a particular target or set of targets is vulnerable.
