The gopher tortoise is a keystone species, meaning other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically. Gopher tortoise burrows provide shelter to over 350 of different animals, ranging from frogs to owls and even endangered indigo snakes.
