Description

Abstract. -- The herpetofauna on the Longhorn Army Ammunition Plant (LHAAP) near Caddo Lake in northeastern Texas were surveyed in each of four forest types: bottomland hardwood, sideslope hardwood, mixed pine-hardwood and upland pine. During 1996 and 1997, 2,028 amphibians of 17 species and 1,397 reptiles of 28 species were captured. Herpetofaunal species richness for the bottomland hardwood, sideslope hardwood, mixed pine-hardwood and upland pine areas were 38, 35, 28 and 28, and abundances were 1,188, 1,373, 526 and 338, respectively. Species composition among the four forest types differed significantly (P = 0.005). A change in elevation created a natural moisture gradient across the four forest types which apparently accounted for the differences in amphibian, snake and turtle assemblages. Differences in lizard assemblages were most likely related to complexity of habitat structure. **********
