The authors conducted an inventory of amphibians and reptiles at Gettysburg National Military Park (GETT) and Eisenhower National Historic Site (EISE) from March-November 1999 and 2000. Both parks are located in Adams County, south-central Pennsylvania. Forest, grassland, wetland, and riparian areas were sampled for presence, relative abundance, and distribution of amphibians and reptiles. They used visual-encounter surveys, coverboards, general searches, funnel traps, drift-fence arrays, pitfall buckets, turtle traps, and leaf litter bags in our inventory.
