About

Current understanding of the distributions of amphibians and reptiles in South Dakota is limited compared to that of many other vertebrate groups and was highlighted in a recent state report. Continuing increases in human population, conversion of grasslands to agriculture, and habitat degradation all likely have strong negative impacts South Dakota’s amphibian and reptile species; however, their effects on species declines are difficult to track because of limited historic and modern sampling and the lack of georeferenced occurrence records. These data often serves as baseline occurrence data to help guide current survey or monitoring efforts, and as such, knowledge of both historic and current occurrence records are essential in order to understand present-day species distributions and declines.

This project was started by and is managed by Drew Davis, a PhD Candidate at the University of South Dakota. Records of over 11,900 specimens (as of September 2017) have been assembled to create a database of all known amphibian and reptile voucher specimens from South Dakota. These records are primarily from voucher specimens deposited at natural history collections from the United States and Canada but the database also includes photographic vouchers from citizen science programs such as HerpMapper and iNaturalist. This website will continue to be updated with new records as they are collected.
