New RMRS products improve national response to drought on rangelands

Science Spotlights Posted on: August 24, 2020
The epic droughts of 2018 in the southwestern US devastated landscapes and economies alike. The Rangeland Production Monitoring System was used to help the Natural Resources Conservation Service and Farm Service Agency identify the most affected areas and seek emergency funding to facilitate re-seeding efforts. 

Efficient cattle production on Colorado ranges

Publications Posted on: February 19, 2020
As an aid to securing increased efficiency in range cattle production, this bulletin presents some of the latest results of investigations made in Colorado by the Rocky Mountain Forest and Range Experiment Station. These results have been obtained on short-grass ranges and on ponderosa pine-bunchgrass ranges and are applicable in general to most of the plains and mountainous areas of the State.

Aerial color and color infrared photography - some applications and problems for grazing resource inventories

Publications Posted on: February 12, 2020
Rangelands in the contiguous United States include over 1 billion acres that are not suitable for cultivated crop production. These lands, however, produce native forage for domestic and wild grazing animals. They also provide recreational and intangible natural beauty benefits and circumscribe the drainages of many river systems from which domestic and commercial water supplies are derived.

Identification and measurement of shrub type vegetation of large-scale aerial photographs

Publications Posted on: February 12, 2020
Important range-shrub species were identified at acceptable levels of accuracy on large-scale (1:600 to 1:1,500) 70 mm color and color infrared aerial photographs (positive transparencies). Identification of individual shrubs was significantly higher, however, on color infrared. Eight of 11 species were identified correctly more than 80 percent of the time on color infrared and two species were correctly identified 100 percent of the time.

Rangeland research at Manitou

Publications Posted on: February 12, 2020
Seventeen years of cattle grazing on ponderosa pine-bunchgrass ranges show that a moderate grazing rate of 30-40 percent use of the dominant grasses and sedges was best for sustained forage and livestock production.

Rangeland watershed management

Publications Posted on: February 12, 2020
Rangeland watershed management deals with the problem of how to use rangelands, not in terms of forage and livestock production alone, but on the basis, that forage production and water yield are interdependent and must therefore be considered together.

Grazing intensity trials on seeded ranges in the ponderosa pine zone of Colorado

Publications Posted on: February 12, 2020
Seeding ranges for the improvement of forage values is now a recognized practice. Depleted ranges and abandoned farmlands in the ponderosa pine zone of Colorado can be successfully seeded (Hull and Johnson, 1955). The kind of grass to plant, when, where, and how, have been determined through research, but comparable information on how to graze seeded ranges is scarce.

Herbage utilization on pine-bunchgrass ranges of Colorado

Publications Posted on: February 12, 2020
To manage any range effectively, the operator needs to know what plants make up the forage supply, their relative value as forage, their ability to withstand grazing, and when and how they are grazed. This paper presents the results of studies to determine how cattle utilize several important species on ponderosa pine-bunchgrass ranges in Colorado.

The effect of grazing intensity on plant composition, vigor, and growth of pine-bunchgrass ranges in central Colorado

Publications Posted on: February 12, 2020
What happens to individual forage plants when subjected to different degrees of grazing by cattle? In what way does grazing change growth habits and composition of the herbaceous vegetation? Answers to these basic questions will help the range operator to properly evaluate his range management practices.

Range seeding in the ponderosa pine zone in Colorado

Publications Posted on: February 12, 2020
Successful range seeding can quickly restore grass on depleted openings or parks in the ponderosa pine zone in Colorado. Research results and experience from numerous seedings in the ponderosa pine zone are summarized in this circular to guide ranchers and range managers in seeding ranges successfully.
