What drives at-risk species richness? Environmental factors are more influential than anthropogenic factors or biological traits

Publications Posted on: December 17, 2018
Species at risk of extinction are not uniformly distributed in space. Concentrations of threatened species may occur where threatening processes are intense, in refuges from those processes, or in areas of high species diversity. However, there have been few attempts to identify the processes that explain the distribution of at-risk species.

Birds of Southwestern grasslands: Status, conservation, and management

Publications Posted on: May 12, 2016
In the Southwestern United States, the grassland avifauna is collectively composed of a mixture of species found primarily in desert grasslands, shortgrass steppe, wet meadows, and alpine tundra (as used here, desert grasslands incorporate both arid grasslands and desert shrub grasslands). Of these habitats, desert grasslands and shortgrass steppe are the most extensive and support the greatest number of grassland bird species.

Assessment of grassland ecosystem conditions in the Southwestern United States: Wildlife and fish. Vol. 2

Publications Posted on: May 12, 2016
This report is volume 2 of a two-volume ecological assessment of grassland ecosystems in the Southwestern United States. Broad-scale assessments are syntheses of current scientific knowledge, including a description of uncertainties and assumptions, to provide a characterization and comprehensive description of ecological, social, and economic components within an assessment area.

Fishes of Southwestern Grasslands: Ecology, Conservation, and Management

Publications Posted on: May 12, 2016
The world possesses an amazing number and variety of freshwater fishes. Fish, the most diverse taxon on Earth, exhibit more species than all vertebrate taxa combined (Hocutt and Wiley 1986, May 1988, Nelson 1994, Matthews 1998) (table 5-1). Worldwide, an estimated 28,500 fish species are in 57 orders and 482 families (Nelson 1994).

Small Mammals, Reptiles, and Amphibians

Publications Posted on: May 12, 2016
This chapter focuses on small mammals, reptiles, and amphibians that inhabit the grasslands within the Southwestern Region of the USDA Forest Service. The chapter is not intended to be an all inclusive list of species, but rather to address the species that play important roles in grassland ecosystems and that often are associated with the management of grasslands. Among the larger rodents discussed here are prairie dogs and pocket gophers.


Publications Posted on: May 12, 2016
This volume addresses the wildlife and fish of the grasslands in the Southwestern Region of the USDA Forest Service. Our intent is to provide information that will help resource specialists and decisionmakers manage wildlife populations within grassland ecosystems in the Southwestern United States. The information and analysis presented is at a Regional scale.

Datasets Posted on: August 27, 2015
This data publication contains capture and telemetry measurements for elk (Cervus elaphus) in the Black Hills National Forest. Radio-collared elk were located 2-3 times per month and behavior observed. These data also include vegetation characterization at 412 locations where the precise location of elk were observed and 509 random locations.

Wildlife population and harvest data for Forest Service 2010 RPA assessment

Datasets Posted on: August 27, 2015
The data documents trends in the populations and harvests of wildlife species across the United States, from 1955 to 2010, as one set of resource condition indicators as required by the Forest and Rangeland Renewable Resources Planning Act (RPA) of 1974. Data from a variety of sources were used to document recent historical trends in big game, small game, migratory game birds, furbearers, nongame, and imperiled species.
