Ecology of Cornsnakes (Pantherophis Guttatus) in the New Jersey Pine Barrens

Abstract

The red cornsnake (Pantherophis guttatus) is a rare and secretive species with a limited and fragmented distribution in the New Jersey Pine Barrens. Consequently, it is a species of concern to conservation agencies. About fifty adult P. guttatus have been radio-tracked over the course of an almost three-year study in order to obtain basic behavioral and habitat selection information. Snakes were located 2-3 times/week for up to 300 days/year. Data analysis was performed using GPS locations and activity parameters collected over the previous two years. Statistical testing performed of the previous two years of data indicate that male and female P. guttatus have similar activity parameters and that their activity areas remain fairly stable from year to year. The third and final year of data will be complete after the start of the 2019-2020 hibernation season and can be analyzed in conjunction with the prior two years. Focusing primarily on the materials needed and methods of data collection, we will discuss the broader implications of the 3-year study’s findings in terms of formulating a conservation plan for this endangered species.
