Small mammal inventory within Olympic National Park, 1998-2000. This study was conducted by USGS. These data reference species, sex, weight, ID number, age, and capture history of small mammals trapped from 1998-2000 in a preliminary study associated with developing a mammalian monitoring program in Olympic National Park. In addition, the data set contains vegetation data characterizing the small mammal trapping station locations.

Inventory of small mammals tabular data in the Fort Clatsop subunit of Lewis and Clark National Historic Park, 2002. In 2001, a small mammal and bat survey was conducted at Fort Clatsop National Memorial (FOCL, now known as Lewis and Clark National Historical Park, or LEWI). Sherman live traps were used to sample in 5 areas of the park, and mist nets were used to sample volant mammals in one additional area of the park. A total of 418 captures representing 242 individual animals of 9 small mammal species were documented as a result of the study. In addition, one bat was captured (long-eared bat - Myotis evotis).

This dataset includes small mammal capture records collected by the National Park Service’s Arctic Inventory and Monitoring Program (Lawler et al. 2009) between 2000 and 2003 (Cook and MacDonald, 2004). Sampling occurred across five National Parklands including Bering Land Bridge National Preserve, Cape Krusenstern National Monument, Gates of the Arctic National Park and Preserve, Kobuk Valley National Park, and Noatak National Preserve. The study was a collaborative effort between the Beringian Coevolution Project at the Museum of Southwestern Biology, University of New Mexico, and the ARCN Inventory and Monitoring Program of the National Park Service, Alaska Region.

An inventory of mammals was conducted during 2004 at nine national park sites in the Northeast Temperate Network (NETN): Acadia National Park (NP), Marsh-Billings-Rockefeller National Historical Park (NHP), Minute Man NHP, Morristown NHP, Roosevelt-Vanderbilt National Historic Site (NHS), Saint-Gaudens NHS, Saugus Ironwork NHS, Saratoga NHP, and Weir Farm NHS. Sagamore Hill NHS, part of the Coastal and Barrier Island Network (NCBN) was also surveyed. Every park, except for Acadia NP, was sampled twice, once in the winter/spring and again in the summer/fall. During the winter/spring visit, indirect measure (IM) sampling arrays were employed at 2-16 stations and included sampling by remote cameras, covered trackplates (i.e., cubby boxes), and hair traps. Indirect measure stations were established and re-used during the summer/fall sampling period. Trapping was conducted at 2-12 stations at all parks except Acadia NP during the summer-fall period and consisted of arrays of small mammal traps, squirrel-sized live traps, and some fox-sized live traps. A total of 38 species was detected by IM sampling, trapping, and field observations. Species diversity (i.e., number of species) varied among parks, ranging from 8-24, with Minute Man NHP having the most species detected. Raccoon (Procyon lotor), Virginia Opossum (Didelphis virginiana), Fisher (Martes pennanti), and Domestic Cat (Felis silvestris) were the most common medium-sized mammals detected in this study and White-footed Mouse (Peromyscus leucopus), Northern Short-tailed Shrew (Blarina brevicauda), Deer Mouse (P. maniculatus), and Meadow Vole (Microtus pennsylvanicus) the most common small mammals detected. All species detected are considered fairly common throughout their range including the Fisher, which has been reintroduced in several New England states. We did not detect any state or federal endangered or threatened species.
