Plant names in boldface are herbaceous perennials; plant names followed by an asterisk were in a dried state (i.e., had already flowered and fruited—see Materials and Methods); # Plants refers to the total number of individual plants for a given species that tortoises fed from (i.e., a plant was counted if a tortoise made at least one bite from that plant). Tortoise scat was eaten on two different occasions by two different tortoises (one male and one female).
