Organizations with Expertise on Desert Tortoises in Nevada


TORTOISE GROUP, a Las Vegas-based organization, emphasizes responsible care of legally-held pet tortoises and protection of wild desert tortoises. This organization achieved non-profit status in 1982 and has three objectives: (1) to provide adoption services for unwanted or displaced pet tortoises; (2) to promote responsible attitudes and actions by providing information and educational programs for the public; and (3) to discourage unauthorized collections of wild tortoises and the release of pets. From 1989 to 2003, Tortoise Group participated in development of the Clark County Habitat Conservation Plan. A representative continues to take part in conservation efforts that are implemented under what is now the Clark County Multiple Species Habitat Conservation Program through education programs. Independent efforts by Tortoise Group members emphasize teaching children through school programs. Tortoise Group volunteers provide adoption services for unwanted or escaped captive tortoises and visit homes of families who have pet tortoises and want to improve their living conditions. The website provides over 20 sheets on care (listed below), a handbook, and other valuable information for owners of captive tortoises.

One of Tortoise Group’s successful programs is providing a complete tortoise chow, which is made by Zeigler Brothers. It is called Megadiet; Dr. Olav Oftedal was influential in developing the formula for this complete diet. Tortoise Group members have used it since the early 1990 and it produces healthy, well-formed tortoises (no pyramidal shells). Common vegetables or other supplements are unnecessary when MegaDiet is used.

The Tortoise Group presents monthly programs with guest speakers for the general public, provides speakers for school classes and other interested groups, and distributes a newsletter. it meets from 1:00-3:00 p.m. on the third Saturday of each month (February through September) at the Nevada State Museum in Lorenzi Park, Las Vegas.
