Under a National Park Service/Wildlife Conservation Society Cooperative Agreement, an inventory of amphibians and reptiles at Acadia National Park (ACAD) in Maine was conducted from March through September 2001. Seven standardized sampling methods were employed; anuran call counts, egg-mass counts, time-constrained search, coverboards, turtle trapping, minnow trapping, and drift fence arrays. In addition, animals encountered outside of standardized surveys (temporally or spatially) were recorded as incidental encounters. Eighteen species were documented including six frog/toad, five salamander, two turtle, and five snake species. These species represent 82% of the species believed to have occurred historically in the park.

Supported by the U.S. Geological Survey and the National Park Service Inventory and Monitoring program an amphibian and reptile inventory was conducted in Grand Teton (GRTE) and Yellowstone (YELL) National Parks from 2000-2003. The work consisted of surveying more than 150 sites in 13 catchments in GRTE and 466 sites in 19 catchments in YELL. The project had three main components: systematic surveys, targeted species surveys, and apex monitoring at a long-term study area. The project provided the first systematically collected amphibian occurrence data for the two parks and included remote areas where amphibians had not previously been documented. The study resulted in an updated list of herpetofauna in the parks, species distribution data, and amphibian disease information. Both ranavirus and chytrid fungal disease were present in amphibian populations in YELL.

An inventory of amphibian species in Biscayne National Park (BISC) was conducted during 2002 and 2003. The goals of the project were to create a georeferenced inventory of amphibian species, use new analytical techniques to estimate proportion of sites occupied by each species, look for evidence of known stressors or problems that may lead to amphibian population decline (invasive species, disease, die-offs, and so forth), and to establish a baseline and methodology that could be used for future monitoring efforts. Visual encounter surveys and anuran vocalization surveys were the primary means of sampling, but opportunistic collections and nighttime road surveys were also used to augment the visual encounter methods for more rare or cryptic species.

This database contains data collected from 3/2004 to 6/2005 at Assateague Island National Seashore for an inventory of amphibians (frogs and salamanders) and reptiles (turtles, lizards and snakes). Survey methods included visual encounter surveys, audio surveys, road surveys, dipnets, minnow traps and turtle traps.

These data are detections of reptiles in 2006 under 2 ft x 2 ft dimension plywood coverboards at four of the 15 sample points at Spears and Didion Ranches, Placer County, California. There are 81 coverboards in a 9 board by 9 board array (on 15 m spacing) centered on the sample points. Coverboards were placed in oak woodland and annual grassland habitat in November-December 2006 and checked on a bi-weekly basis between March-July 2006. All 204 animals found under the coverboards were counted, identified to species, and aged and sexed.
