Increasing focus on assessment of vulnerability to climate change has highlighted the need for tools that integrate a vast scientific literature into accessible approaches. NatureServes Climate Change Vulnerability Index is a popular tool that allows fairly quick screening of plant and animal species for vulnerability to climate change. The Index allows input on exposure to changing climates, sensitivity to climate change, and documented or modeled responses to climate change. Assessment output allows comparison among species vulnerability and rapid identification of causal factors. During the webinar, we will describe when to use the Index, show how it works, and review results of completed assessments.
