From June 23-28 and on August 6, 2002, Mount Rainier Wildlife Program staff conducted a small mammal inventory, a rapid assessment of bat species, and documented the presence of other mammals in the area at Fort Vancouver National Historical Site (FOVA) and parts of the Vancouver National Historic Reserve (Reserve). Our small mammal inventory focused on live trapping in seven habitat types for 600 trap-nights. We captured 74 unique individuals of five different species (+ two unknown) and documented two additional species incidentally. The most frequently-trapped species was the deer mouse (Peromyscus maniculatus). We collected eight voucher specimens to include at least one of each of the five species trapped. We were unable to capture bats in one night of mist-netting in the Reserve but did identify big brown bat (Eptesicus fuscus) calls using an electronic bat detector and visually documented likely two different Myotis species.

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 database contains field survey data collected between 2002 and 2004 for a inventory of mammals at COLO, GEWA, and THST. Surveys relied on live trapping with Sherman, Tomahawk, and pitfall traps for small to medium-size mammals, direct observation of individuals and their sign, and remote photography. Various habitats were targeted for sampling sites. Twenty-seven species were either captured or observed in COLO, twenty-one in GEWA, and twelve in THST.

Bat community data were collected in various watersheds in Olympic National Park. This data set contains records of acoustic detections, physical measurements, and reproductive attributes of the species of bats observed from 1998 to 2000. In addition to call detections and physical attributes, vegetation is characterized at each sampling site, and precipitation, weather and lunar phases are described for each sampling period.

In 2022, an estimated 1.6 million people visited New River Gorge (NPS 2023b). To date, there are over 1,600 established rock climbs documented in the New River Gorge area (Mountain Project 2022, Williams 2019). As visitation has increased, NERI has become interested in documenting the presence of bat species and their habitat on and near the cliff face, rim, and base areas to support a park management plan. A total of 51 routes were selected to survey three times throughout the summer of 2022. Cliff line surveys included personnel on-rope rappelling down each selected cliff face to look for bats or bat sign and to collect data on the physical attributes and record habitat information. In addition, a simultaneous acoustic survey for bats was conducted at the base of each survey route. Although no bats or bat sign were documented, analysis of the acoustic data in concert with the environmental factors revealed that bats were detected at more highly climbed walls versus unclimbed walls, at least northern long-eared bats (Myotis septentrionalis) were more likely to be detected near less vegetated walls, and activity of eastern small-footed bats (Myotis leibii) was higher as the summer progressed. Bats that roost on rock walls use cracks and crevices, which are also an important feature for climbers. Opportunistic conversations with climbers revealed that bats are observed on the cliffs. Colorado State University has a Climbers for Bat Conservation group (CSU 2023) that could be a resource for engaging climbers in a citizen science campaign.

Vector datasets of CWHR range maps are one component of California Wildlife Habitat Relationships (CWHR), a comprehensive information system and predictive model for Californias wildlife. The CWHR System was developed to support habitat conservation and management, land use planning, impact assessment, education, and research involving terrestrial vertebrates in California. CWHR contains information on life history, management status, geographic distribution, and habitat relationships for wildlife species known to occur regularly in California. Range maps represent the maximum, current geographic extent of each species within California. They were originally delineated at a scale of 1:5,000,000 by species-level experts and have gradually been revised at a scale of 1:1,000,000. For more information about CWHR, visit the CWHR webpage (https://www.wildlife.ca.gov/Data/CWHR). The webpage provides links to download CWHR data and user documents such as a look up table of available range maps including species code, species name, and range map revision history; a full set of CWHR GIS data; .pdf files of each range map or species life history accounts; and a User Guide.

These data were compiled to improve our understanding of bat foraging along the Colorado River in Grand Canyon. Objectives of our study were to determine whether bat activity was influenced primarily by variation in prey availability relative to other environmental or geomorphic factors. These data represent 1,428 paired samples of bat activity and insect abundance calculated as catch rates collected on 611 sampling nights at 410 sampling sites throughout a 470 km segment of river. These data were collected from April to October in 2017-2020 at recreational camps along the Colorado River in Grand Canyon between Glen Canyon Dam and Pearce Ferry. These data were collected through a U.S. Geological Survey led community science program that recruited recreational river runners to sample insects using light traps and to record bat activity using handheld acoustic recorders. Sampling was conducted for one hour at dusk during each night of the river expedition. These data can be used to interpret changes in total bat activity and insect catch rates over time and space relative to environmental variables.

This dataset is a backup of the data stored on NABat.org, for NABat stationary acoustic monitoring on national wildlife refuges in the Pacific Region for years 2016-2022. It was directly downloaded from NABat to update FWSpecies lists on refuges. Significant post-processing was required in order to verify data and locations, and correct errors. This post-processing resulted in an enhanced dataset specific for region 1 refuges.
