State-and-transition simulation model (ST-Sim): Predicting landscape conditions

Tools Posted on: July 16, 2019
How does a land manager make a decision today that will impact landscapes decades into the future? With the uncertain influence of climate change and its associated stressors, it’s an increasingly thorny question. 

Rangeland health: New methods to classify, inventory, and monitor rangelands

Documents and Media Posted on: October 03, 2018
Times are changing in the American rangelands! This well written and illustrated National Research Council report calls for a comprehensive shift in the way U.S. Federal Agencies [e.g. Bureau of Land Management (BLM) and the Soil Conservation Service (SCS)] monitor and assess publicly owned rangelands. The committee's recommendations are quite relevant to Australian rangelands management; much of it is based on Australian research! Document Type: Other Documents

Development of the Rangeland Production Monitoring Service could improve rangeland management

Projects Posted on: July 24, 2018
Rangeland managers and livestock producers need timely and consistent tools that can inform grazing strategies, risk management, and allotment management plans. On the ground monitoring is expensive and resources can be limited, making it difficult to do consistently. The new Rangeland Production Monitoring Service can help make monitoring processes more effective and easier to implement.

Northeastern California plateaus bioregion science synthesis

Projects Posted on: April 20, 2018
The Lassen and Modoc National Forests are revising their Forest Plans, guided by the 2012 Planning Rule. This requires public and tribal input throughout the process and embraces the fact that ecological, social, and economic objectives are interrelated. Because ecological, social, and economic conditions have changed since the original forest plans were written and new science is available, preparing a science synthesis, guided by input from the public, tribes, and forest staffs, is the first step in a multi-step process that eventually leads to revised forest plans.

Rangeland resource trends in the United States: A technical document supporting the 2000 USDA Forest Service RPA Assessment

Publications Posted on: May 12, 2016
This report documents trends in America's rangelands as required by the Renewable Resources Planning Act of 1974. The Forest Service has conducted assessments of the rangeland situation for 30 years. Over this period, rangeland values and uses have gradually shifted from concentrating upon forage production and meeting increasing demand for red meat to a more broad-based understanding under a framework of sustainable resource management.

Mechanisms of range expansion and removal of mesquite in desert grasslands of the Southwestern United States

Publications Posted on: May 12, 2016
During the last 150 years, two species of mesquite trees in the Southwestern United States have become increasingly common in what formerly was desert grassland. These trees have spread from nearby watercourses onto relatively xeric upland areas, decreasing rangeland grass production. Management attempts to limit or reverse this spread have been largely unsuccessful.

Prescribed fire, soil inorganic nitrogen dynamics, and plant responses in a semiarid grassland

Publications Posted on: October 05, 2015
In arid and semiarid ecosystems, fire can potentially affect ecosystem dynamics through changes in soil moisture, temperature, and nitrogen cycling, as well as through direct effects on plant meristem mortality. We examined effects of annual and triennial prescribed fires conducted in early spring on soil moisture, temperature, and N, plant growth, and plant N content in semiarid shortgrass steppe.

Desert Experimental Range: Annotated bibliography

Publications Posted on: October 21, 2013
Entries qualify for inclusion if they were conducted in whole or part at the Desert Experimental Range (DER, also known as the Desert Range Experiment Station) or were based on DER research in whole or part. They do not qualify merely by the author having worked at the DER when the research was performed or prepared. Entries were drawn from the original abstracts or summaries when those were included in the original document.

Southern Idaho student "bug crews": Weeds, youth, and biocontrol in the rangelands of Idaho

Publications Posted on: November 17, 2011
Biological control of noxious weeds is an effective and widespread method often used by rangeland managers in the western United States. However, once biological control agents, usually insects, are released onto public and private lands there are few, if any, programs to follow up and monitor the effectiveness of these agents. A technique being used by some land managers is the use of student crews to implement monitoring programs.

Rangeland mismanagement in South Africa: Failure to apply ecological knowledge

Publications Posted on: September 10, 2007
Chronic, heavy livestock grazing and concomitant fire suppression have caused the gradual replacement of palatable grass species by less palatable trees and woody shrubs in a rangeland degradation process termed bush encroachment in South Africa. Grazing policymakers and cattle farmers alike have not appreciated the ecological role fire and native browsers play in preventing bush encroachment.
