Handbook on Gopher Tortoise (Gopherus polyphemus): Health Evaluation Procedures for Use by Land Managers and Researchers

摘要

The gopher tortoise is a widespread species, but one at risk. Recently, greater interest in the survival of the species has led to a series of programs and proposals for a region-wide program of cooperative management. Relocating the animals when their habitat is threatened by human disturbance is a common management practice on all lands. However, the health of the tortoises may influence the success of these relocations. A process to better incorporate health and disease related information into management decision making was identified as an important missing element. The newly developed handbook contains decision trees, charts and other aids, including a special section identifying warning signs of serious health problems. The handbook thus facilitates decision making regarding the health status of gopher tortoises by land managers, military and otherwise, when developing management plans involving relocation or augmentation of tortoise populations on their lands. The primary emphasis is on basic physical examinations of gopher tortoises because the manual is designed for use by land management personnel. This handbook is part of a larger project initiated within the U.S. Army environmental research program to address specific gaps in information regarding gopher tortoise population ecology and health.
