Management opportunities and research priorities for Great Plains grasslands

Publications Posted on: September 26, 2019
The Great Plains Grassland Summit: Challenges and Opportunities from North to South was held April 10-11, 2018 in Denver, Colorado to provide syntheses of information about key grassland topics of interest in the Great Plains; networking and learning channels for managers, researchers, and stakeholders; and working sessions for sharing ideas about challenges and future research and management opportunities.

Climate change vulnerability assessments for the Front Range and Colorado National Grasslands

Projects Posted on: April 24, 2019
Climate Change Vulnerability Assessment in Support of Front Range National Forests and Colorado National Grasslands for Forest Plan Revision, Plan Amendments, and Project-Level Planning.

The Rangeland Vegetation Simulator: A decision support tool for monitoring and projecting grassland conditions

Publications Posted on: December 06, 2018
Rangeland landscapes occupy roughly 662 million acres in the coterminous U.S. (Reeves and Mitchell 2011) and their vegetation responds quickly to climate and management, with high relative growth rates and inter-annual variability. Current national decision support systems in the U.S.

Restoration of temperate savannas and woodlands [Chapter 11]

Publications Posted on: October 04, 2017
Savannas and woodlands are open forest phases that occur along a gradient between grasslands and closed canopy forests. These ecosystems are characterized by open to nearly closed canopies of overstorey trees, relatively sparse midstorey and understorey woody vegetation, and dense, species-rich ground flora. In contrast to closed forests, the dominant and codominant trees in the canopy of open forests often have large, spreading crowns.

Effects of climate change on rangeland vegetation in the northern Rockies [Chapter 6]

Publications Posted on: October 02, 2017
A longer growing season with climate change is expected to increase net primary productivity of many rangeland types, especially those dominated by grasses, although responses will depend on local climate and soil conditions. Elevated atmospheric carbon dioxide may increase water use efficiency and productivity of some species.

Scientists conserve the seeds of today to propagate the best adapted plants of tomorrow

Science Spotlights Posted on: October 13, 2016
Faced with extensive disturbances and climatological challenges that are rapidly changing ecosystems, scientists and land managers require the seeds of today to provide the plants of tomorrow. Researchers are currently studying more than 50 plant species in order to select best adapted plants to current and future climate conditions.

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.

Biodiversity, functional processes, and the ecological consequences of fragmentation in Southwestern grasslands

Publications Posted on: May 12, 2016
Concern over accelerating extinction rates and loss of species diversity on a global scale was the subject of E.O. Wilson's seminal volume Biodiversity (Wilson 1988). This work essentially transformed the term "biodiversity" into a household word as a short-hand for species diversity--or more simply, the full array and variety of living organisms on Earth.

Large native ungulates

Publications Posted on: May 12, 2016
This chapter addresses the large native ungulates (American bison (Bos bison), elk (Cervus elaphus), white-tailed deer (Odocoileus virginianus), mule deer (Odocoileus hemionus), and pronghorn (Antilocapra americana) of the grasslands. The information presented includes historical background, description of the species’ biology and ecology, and management in relation to domestic animals.

Assessment of grassland ecosystem conditions in the Southwestern United States. Vol. 1

Publications Posted on: May 12, 2016
This report is volume 1 of a two-volume ecological assessment of grassland ecosystems in the Southwestern United States. Broadscale 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.
