CLIMATE CHANGE ALBERTAS BIODIVERSITY 25 Higher Vulnerability Medial Vulnerability VULNERABILITY SCORE SPECIES 10 5 0 5 10 15 Lower Vulnerability FIGURE 6. Vulnerability scores for 173 Alberta species. This ranking highlights species that are most and least vulnerable to the expected changes in climate and can support prioritization of species for further research or management action Shank and Nixon 2014. For each species assessed detailed information is available at httpwww.biodiversityandclimate.abmi.caresources PurplePitcherPlantslikemanyAlberta plantshaveverylimiteddispersalabilities. Asaresulttheirpopulationsmightbecome strandedinunfavourableconditionsasclimate changeoccursaroundthem.ThePurplePitcher Plantwasoneofthemostclimate-vulnerable plantspeciesassessed. Although migratory species like the Harlequin Duck are able to easily disperse to areas where the habitat and climate are suitable the preference of this species for cool mountain streams makes it moderately vulnerable to climate change in Alberta. In part because of their reliance on ephemeral wetlands for breeding grassland amphibians like this Great Plains Toad are highly vulnerable to climate change. Of the ten amphibians assessed six ranked in the top 25 most vulnerable species to climate change in Alberta. The Coyote is a wide ranging and adaptable species that has relatively low vulnerability to climate change.
