Estimated Probabilities from Lidar Models for Marbled Murrelet (Brachyramphus marmoratus) Occupancy in Forest Vegetation Stands in the Siuslaw National Forest, Oregon

We developed a LiDAR-based habitat model for the threatened Marbled Murrelet (MAMU) in the Siuslaw National Forest, Oregon, using a two-step approach. First, we tested the applicability of the LiDAR-based model developed for the Coos Bay District of the Bureau of Land Management (BLM) to the Siuslaw N.F. In the second step, we tested alternative habitat models developed with forest structural data

Beaver-related Stream Restoration Projects in Western Rangelands

We systematically surveyed federal and state wildlife biologists, hydrological specialists, non-profit organizations, and working groups focused on beaver or wetland restoration in the western U.S. We focused primarily on contacting land managers from states containing some portion of the Great Basin, although many of the projects described in surveys fell outside of this watershed. Some land mana

Mariana swiftlet (Aerodramus bartschi) survey data from O'ahu, Hawai'i, 2005-2006

Defining full life cycle biology is critical for comprehensive conservation planning. To that end, life history information on the endangered Mariana swiftlet (Aerodramus bartschi) is scarce. Therefore, this study examined the reproductive biology of the Mariana swiftlet over five annual cycles on the island of Oahu in the Hawaiian Islands. This introduced population used a human-made tunnel for r

DNA yields and concentrations from buccal swab samples of red-cockaded woodpeckers

The data were generated as part of a study to determine if buccal (oral) swabs could be used to obtain genetic material from Red-Cockaded Woodpecker chicks. Different swab types were investigated to determine if any specific type gave the highest DNA yields.

Western US Ruggedness Reclassified into 6 Classes

"Vector Ruggedness Measure (VRM) measures terrain ruggedness as the variation in three-dimensional orientation of grid cells within a neighborhood. Vector analysis is used to calculate the dispersion of vectors normal (orthogonal) to grid cells within the specified neighborhood. This method effectively captures variability in slope and aspect into a single measure. Ruggedness values in the output

Western Pond Turtle (Actinemys marmorata) Monitoring and Assessment Data from the Trinity River, California (2013-2017)

A key objective of the Trinity River Restoration Program (TRRP) is maintaining and enhancing other wildlife populations through the restoration initiatives. For herpetological species, the foothill yellow-legged frog and western pond turtle have been identified as important species on which to focus monitoring efforts due to their status as California state-listed Species of Concern. As a result,

Microsatellite markers, habitat quality, and sample location data for Northern Spotted Owls (Strix occidentalis caurina)

The data are included in 8 separate text files: 1) "Sample_coordinates.txt". The file contains sample identifiers along with geographic coordinates associated with each sample. Coordinates are specified as UTM Zone 10 values (WGS84). 2) "Sample_genotypes.txt". The file contains a sample identifier along with microsatellite genotypes associated with each sample. 3) "uniform_conductances.asc". An

Vegetation data from Columbia spotted frog (Rana luteiventris) exclosure study in eastern Oregon

We studied the short-term effects of full and partial livestock grazing exclosures on Columbia Spotted Frog (CSF; Rana luteiventris) populations using a controlled manipulative field experiment with pre- and post-treatment data. This dataset includes vegetation data collected 2002-2010 and 2013 at 94 lakes and ponds in and around the Blue Mountains in eastern Oregon. Data collection followed stand

Streamflow Observation Points in the Pacific Northwest, 1977-2016

This dataset includes spatial locations in the Pacific Northwest where streamflow observations were recorded. For the purpose of this investigation, all streamflow observations were converted into wet or dry indicator values.

Stream temperature and drying data from Willow/Whitehorse watersheds, southeast Oregon, 2014-16, and Willow/Rock/Frazer watersheds, northern Nevada, 2015-2016

These tabular, spatial, and code data sets were created in support of a stream temperature and drying study that took place in the Willow and Whitehorse watersheds of southeastern Oregon from 2014-2016 and the Willow, Rock, and Frazer watersheds of northern Nevada from 2015-2016. A prior data release of stream temperature data and associated spatial data from the Willow and Whitehorse watersheds o

Created snag characteristics and cavity-nesting bird associations in the CFIRP stands, McDonald-Dunn Research Forest, Corvallis, OR, USA, 2016

Snags provide critical habitat for nearly one-third of wildlife species in forests of the Pacific Northwest, so historic declines in snags are thought to have had a strong impact on biodiversity. Resource managers often create snags to mitigate the scarcity of snags within managed forests, but information regarding the function and structure of created snags across long time periods (20 years) is

Compilation of BLM Monitoring Reports Assessing Post Wildfire Seeding of Rangelands, 2001-2009

Post-fire rehabilitation seeding in the U.S. Intermountain West, primarily conducted by the Bureau of Land Management, is designed to reduce the risk of erosion and weed invasion while increasing desirable plant cover. Seeding effectiveness is typically monitored for three years following treatment, after which a closeout report is prepared. We evaluated 220 third-year closeout reports describing
