Ornate Box Turtle (Terrapene ornata) Demography in Illinois

Abstract

There are few remaining sites in Illinois supporting populations of the Ornate Box Turtle (Terrapene ornata), and those where the species can still be found are small and isolated. Habitat loss due to agriculture, road mortality, and collection for the pet trade are thought to have caused State-wide decline. While Ornate Box Turtles still occur at several remnant prairie reserves in Illinois, the vital rates and demography of these populations are not known. Using capture-mark-recapture surveys, we developed estimates of survival and fecundity at two sites and estimated population size. We then used vitals rates in deterministic demographic models to examine their effect on population growth. The study provides guidance for site managers and helps highlight areas of research still needed to better understand their population status in the state.
