Biological assessment of oil and gas development on the Little Missouri National Grassland

Publications Posted on: November 15, 2018
The Little Missouri National Grassland is the largest designated National Grassland in the United States and represents one of the best examples of intact native mixed-grass prairie in the United States. The Little Missouri National Grasslands occurs entirely within the Williston Basin, which has been a leading source of conventional oil and gas production since the 1950s.

Forest Service science bolsters sagebrush and sage-grouse conservation

Media Gallery Posted on: September 16, 2016
Sagebrush ecosystems are among the largest and most threatened ecosystems in North America. Greater sage-grouse has served as the bellwether for species conservation in these ecosystems and has been considered for listing under the Endangered Species Act several times. The 2016 Conservation and restoration of sagebrush ecosystems and sage-grouse: An assessment of USDA Forest Service Science assessment will help meet continuing widespread concerns and calls for science-based conservation to mitigate threats to sagebrush ecosystems, conserve populations of sage-grouse and other sagebrush-obligate species, and restore sagebrush ecosystems throughout the western United States. 

Forest Service science bolsters sagebrush and sage-grouse conservation

Science Spotlights Posted on: August 19, 2016
USDA Forest Service (FS) has been a leader for several decades in developing science and applications to support conservation and restoration of sagebrush ecosystems and sage-grouse populations. This spotlight describes an assessment that explains how and why understanding and supporting FS science is crucial for future management of sagebrush ecosystems.

Greater sage-grouse winter habitat use on the eastern edge of their range

Publications Posted on: June 27, 2013
Greater sage-grouse (Centrocercus urophasianus) at the western edge of the Dakotas occur in the transition zone between sagebrush and grassland communities. These mixed sagebrush (Artemisia sp.) and grasslands differ from those habitats that comprise the central portions of the sage-grouse range; yet, no information is available on winter habitat selection within this region of their distribution.

Resource selection during brood-rearing by Greater Sage-Grouse [chapter 12]

Publications Posted on: December 20, 2011
Understanding population dynamics and resource selection is crucial in developing wildlife resource management plans for sensitive species such as Greater Sage-Grouse (Centrocercus urophasianus). Little is known about sage grouse habitats on the eastern edge of their range. We investigated resource selection of Greater Sage-Grouse during brood- rearing in North and South Dakota during 2005-2007.

Dynamics of a threatened orchid in flooded wetlands

Publications Posted on: September 23, 2008
One of the three largest metapopulations of the western prairie fringed orchid (Platanthera praeclara) occurs on the Sheyenne National Grassland, in southeastern North Dakota. Our study was initiated in 1993 to quantify the effect of flooding on individual orchid plants.

Factors influencing woodlands of southwestern North Dakota

Publications Posted on: February 05, 2008
Literature pertaining to woodlands of southwestern North Dakota is reviewed. Woodland species composition and distribution, and factors influencing woodland ecosystems such as climate, logging, fire, and grazing are described. Potential management and improvement techniques using vegetation and livestock manipulation have been suggested.

Use of Data Layering to Address Changes in Nitrogen Management Zone Delineation

Publications Posted on: March 05, 2007
Use of N management zones appears to be a practical method of revealing dominant patterns of residual soil nitrate in North Dakota crop fields, where fall soil nitrate sampling is a common N management tool. Delineation of zone boundaries to date has been a largely subjective process. A weighted, classified method of delineating nitrogen management zones is presented.

Quantifying suitable habitat of the threatened western prairie fringed orchid

Publications Posted on: July 27, 2006
Land managers need accurate and quick techniques to identify suitable habitat of species of interest. For species protected by federal or state laws, identification of suitable habitat is critical for developing a conservation strategy that includes reestablishing populations and altering management to address this need.

Effects of grazing management treatment on grassland plant communities and prairie grouse habitat

Publications Posted on: July 24, 2006
Seasonlong grazing treatments show no benefit to grass basal cover and visual obstruction is not adequate. Pastures with one grazing period in mid season show no positive change in grass basal cover but have better visual obstruction than seasonlong. Deferred grazing decreases basal cover of warm season grasses and visual obstruction reduced to inadequate levels the first growing season after treatment.
