The soils of the LBJ Ranch District consist of sand, silt and clay in the lower areas and interbedded limestone, dolomite and marl at the higher elevations. These are all part of the Luckenbach-Pedernales-Heatly Association. In general, these soils are moderately well drained; permeability is moderately slow; and runoff is moderate. Cropland is a well-suited use of these soils.

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)
