A variety of reptile species have been identified within the boundaries of Lyndon B. Johnson National Historical Park. The five common turtles inventoried include the Common Snapping Turtle (Chelydra serpentina serpentina), Texas Map Turtle (Graptemys versa), Red-eared Slider (Trachemys scipta elegans), Texas Cooter (Pseudemys texana), and Guadalupe Spiny Softshell (Apalone spinifera guadalupensis).
The Mediterranean Gecko (Hemidactylus turcicus) is a common exotic found inhabiting many of the structures.

An invasive plant that Lyndon B. Johnson National Historical Park has problems with just happens to be a non-native grass called Johnson Grass. Besides being tough to get rid of, it is poisonous to livestock if eaten just after a freeze. (photo ©Barry A. Rice/The Nature Conservancy)
