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.

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.

This database contains data collected from 3/13/2001 to 8/5/2003 at Colonial National Historical Park, George Washington Birthplace National Monument and Thomas Stone National Historic Site 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.

From April 2000 to November 2004 (44 months), various field methods were used to capture of encounter reptiles in GSMNP, including placement of metal roofing tin cover, visual encounter searches, drift fences with funnel traps, baited aquatic turtle traps, and searches for road kills. Over the course of the survey, 1,355 individuals of 33 species were encountered. Two new reptile occurrences were confirmed for the park--the common musk turtle (Sternotherus odoratus) and the Cumberland slider turtle (Trachemys scripta troostii)--bringing the total number of reptile species historically recorded from the park to 38. The five most commonly encountered species in our survey were the Eastern Garter Snake (Thamnophis sirtalis), Northern Black Racer (Coluber constrictor), Copperhead (Agkistrodon contortrix), Ringneck Snake (Diadophis punctatus), and the Northern Water Snake (Nerodia sipedon). Five species historically recorded from the park were not encountered during the survey: the Northern Scarlet Snake (Cemophora coccinea), Pine Snake (Pituophis melanoleucus), Southeastern Crowned Snake (Tantilla coronata), Eastern Slender Glass Lizard (Ophisaurus attenuatus), and the Coal Skink (Eumeces anthracinus).

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.

An inventory of amphibians and reptiles was conducted at Death Valley National Park (DEVA) in 2002- 2004 as part of the National Park Service Inventory and Monitoring Program in the Mojave Desert Network. Objectives for this inventory were to: 1) Inventory and document the occurrence of reptile and amphibian species occurring at DEVA, primarily within priority sampling areas, with the goal of documenting at least 90% of the species present; 2) document (through collection or museum specimen and literature review) one voucher specimen for each species identified; 3) provide a GIS-referenced list of sensitive species that are federally or state listed, rare, or worthy of special consideration that occur within priority sampling locations; 4) describe park-wide distribution of federally- or state-listed, rare, or special concern species; 5) enter all species data into the National Park Service NPSpecies database; and 6) provide all deliverables as outlined in the Mojave Inventory and Monitoring Network Biological Inventory Study Plan. Methods included daytime and nighttime visual encounter surveys, road driving, and pitfall trapping. Survey effort was concentrated in predetermined priority sampling areas, as well as in areas with a high potential for detecting undocumented species. 37 species were recorded during surveys, including two species new to the park. During literature review and museum specimen database searches, study authors recorded three additional species from DEVA, elevating the documented species list to 40 (four amphibians and 36 reptiles). Based on these surveys, as well as literature and museum specimen review, this study estimates an overall inventory completeness of 92% for Death Valley and an inventory completeness of 73% for amphibians and 95% for reptiles.
