Habitat use data for male ruffed grouse in the Black Hills National Forest

Datasets Posted on: March 27, 2015
Ruffed grouse (Bonasa umbellus) are native upland game birds and a management indicator species (MIS) for aspen (Populus tremuloides) in the Black Hills National Forest in South Dakota and Wyoming. Drumming surveys were conducted in the spring of 2007 and 2008 to locate used and unused male ruffed grouse sites from which habitat characteristics were compared at increasing spatial scales of 200 meters (m), 400 m, 1600 m, and 4800 m.

Multi-scale habitat use of male ruffed grouse in the Black Hills National Forest

Publications Posted on: September 26, 2014
Ruffed grouse (Bonasa umbellus) are native upland game birds and a management indicator species (MIS) for aspen (Populus tremuloides) in the Black Hills National Forest (Black Hills). Our objective was to assess resource selection of male ruffed grouse to identify the most appropriate scale to manage for aspen and ruffed grouse in the Black Hills.

Widespread triploidy in western North American aspen (Populus tremuloides)

Publications Posted on: September 17, 2013
We document high rates of triploidy in aspen (Populus tremuloides) across the western USA (up to 69% of genets), and ask whether the incidence of triploidy across the species range corresponds with latitude, glacial history (as has been documented in other species), climate, or regional variance in clone size.

Continental-scale assessment of genetic diversity and population structure in quaking aspen (Populus tremuloides)

Publications Posted on: September 17, 2013
Aspen populations in the south-western portion of the range are consistent with expectations for a historically stable edge, with low within-population diversity, significant geographical population structuring, and little evidence of northward expansion.

Molecular tools and aspen management: A primer and prospectus

Publications Posted on: June 28, 2013
Aspen (Populus tremuloides) isaniconic species in North American landscapes, highly valued for recreation, fiber, wildlife and livestock forage, carbon sequestration, biodiversity, and as a fuelbreak. However, there are rising concerns about the ability of aspen to persist in portions of its range, based on bioclimatic modeling, physiological thresholds and mortality surveys.

Decline of aspen (Populus tremuloides) in the Interior West [Abstract 1]

Publications Posted on: May 03, 2013
Western aspen forests are unique because they reproduce primarily by suckering from the parent root system. Generally a disturbance or die back is necessary to stimulate regeneration of the stands. Unlike other tree species, if aspen stands are lost from the landscape, generally they will not return through natural processes.

Decline of aspen (Populus tremuloides) in the Interior West [Abstract 2]

Publications Posted on: May 03, 2013
It is commonly recognized that aspen (Populus tremuloides) ecosystems in the Interior West provide numerous benefits: (1) forage for livestock, (2) habitat for wildlife, (3) water for downstream users, (4) esthetics, (5) sites for recreational opportunities, (6) wood fiber, and (7) landscape diversity.

Vegetation species diversity inside and outside exclosures in sagebrush, salt desert shrub, and aspen communities

Publications Posted on: May 03, 2013
Vegetation was sampled inside and outside eight exclosures in salt desert shrub and sagebrush vegetation types in Southwestern Wyoming and eight exclosures in aspen vegetation in southern Utah. Only species richness has been examined thus far. Five of the eight Wyoming exclosures had an average of 11% more plant species present outside the exclosure than inside.
