Lizards are expected to be an early warning system of impending change in vegetation communities, and a useful tool in predicting adaptive management needs. This study is conducted in the area with the highest diversity of lizards in the USA, situated at an ecotone between two deserts and a mountain range. Changes in the lizard community are expected sooner in this ecotone than in distinct habitat types, and are also expected to precede observed changes in vegetation.
One of North America’s rarest reptiles, the Louisiana pine snake, may require extra assistance to persist under climate change. Scientists with the Southern Research Station are developing an RRTH (relocation, reintroduction, translocation, headstarting) project for these reptiles.
The SAVS uses an online questionnaire with 22 criteria to predict vulnerability or population response of species to provide a framework for assessing vulnerability to future climate change. The 22 multiple-choice questions are grouped into four categories by theme: habitat, physiology, phenology and biotic interactions. The questionnaire is completed using information gathered from published materials, personal knowledge, or expert consultation.
SAVS uses an online questionnaire with 22 criteria to predict vulnerability or resilience of an individual species to future climate change. Numerical scores indicating vulnerability or resilience for terrestrial vertebrate species are generated.
An analysis of potential national effects of climate change on wildlife habitat is being addressed by RMRS scientists through the estimation of an index of climate change stress to terrestrial biodiversity in order to identify regional hotspots of climate change impacts. This research focuses on management strategies for climate change in the states' Wildlife Action Plans.
