The large number of at-risk and range-restricted species in the South Atlantic are a critical part of our biodiversity. Many of the indicators are designed to incorporate their needs, but in testing a few years ago we noticed there were a few that seemed to be slipping through the cracks. Results of a follow-up project targeting some of these species are now available.

The project is a collaboration with the Natural Heritage Programs within the South Atlantic. It developed distribution models for smooth coneflower, Piedmont fameflower, chaffseed, Michaux’s sumac, Southern hognose snake, striped newt, gopher frog, pondberry, frosted flatwoods salamander, and Curtiss’ loosestrife. We’re working on using these results to improve the South Atlantic Ecosystem Indicators and Conservation Blueprint.

You can explore and download these data on the South Atlantic Conservation Planning Atlas (CPA). You will find the at-risk and range restricted species gallery in the “recommended items” section of the CPA hope page. From this gallery, you can download the final report and the model results for each species.

You can also use the CPA to explore the spatial data by opening the species models in the CPA mapping application. The image below shows the thresholded binary model based on ‘maximum of sensitivity plus specificity’ for the Heterodon simus (Southern hognose snake) as it displays in the CPA. You can explore the other model results for this species by checking/unchecking the boxes in the “Layers” window.
