RRSR Highlights

  • How do I make a drought plan?

Drought is inevitable. This handbook created by the Colorado Agricultural Drought Advisors team with help from USDA-ARS can help producers manage risks ahead of time.

  • Grazing management for grassland bird habitat

This CSU Extension fact sheet shows how grazing management can support grassland bird habitat. It features co-produced research from ARS scientists and rangeland stakeholders in the Collaborative Adaptive Rangeland Management study at the Central Plains Experimental Range.

  • Using long-term forecasts for stocking decisions podcast

EJ Raynor (USDA-ARS) and Retta Bruegger (Colorado State Extension) discuss an 80-year project on how long- and short-term climate and weather correlates to production on ranches, and a decision tree tool that can be used to make management decisions.

  • What does resilience mean to western ranchers? 

This story map shows results from interviews and focus groups with livestock producers across the Western U.S.

The Rangeland Resources and Systems Research Unit has supported multiple long-term research programs including the International Biome Program (IBP), the U.S. Long-Term Ecological Research (LTER) network, and currently, the USDA Long-Term Agroecosystem Research (LTAR) network. ARS scientists and their collaborators work together on interdisciplinary research addressing specific stakeholder and national issues in rangeland management.  Approximately 120 data sets contributing to these research efforts are discoverable in Ag Data Commons, a digital repository curated by the National Agricultural Library.  For specific questions regarding access to data, please contact our data manager, Nicole Kaplan.





The Rangeland Resources & Systems Research is located in Cheyenne, WY and is part of the Plains Area.
