U.S. Climate Resilience Toolkit

For the six states of the U.S. Southwest (Arizona, California, Colorado, Nevada, New Mexico, and Utah)i , January 2020 through August 2021 have been exceptional in the instrumental climate record since 1895, with the lowest total precipitation and the third-highest daily average temperatures recorded, which together imposed an unyielding, unprecedented, and costly drought. This exceptional drought punctuates a two-decade period of persistently warm and dry conditions throughout the region. 

The Western Governors’ Association and the U.S. Department of Agriculture are pursuing an effort to meaningfully address the large-scale infestation of invasive annual grasses on western forests and rangelands. One product of this effort is this toolkit for land managers working to combat the spread of invasive annual grasses in the West. The toolkit is comprised of a roadmap for invasive grass management, with new best management practices; case studies highlighting the application of these practices in Idaho and Wyoming; and a new geospatial data layer (which uses analytical tools to compile existing federal data) to help state and local managers assess invasive annual grasses within their jurisdictions while also offering opportunities to identify new cross-boundary collaborative projects. The roadmap and data layer are designed for easy integration into local management plans and can be tailored by state and local managers to reflect local data, knowledge, capacities, and priorities. 

The heavy precipitation and flooding of 2019 was one for the history books. This report looks back at the major climate events and impacts of 2019 in the Missouri River Basin.

The Northern Plains has experienced increased weather variability and climatic changes throughout the 20th and early 21st centuries. This assessment presents observed changes, such as increased length of frost-free seasons, which pose risks and opportunities to agricultural production in the region. The assessment also highlights adaptation practices working land managers might consider to prepare for and respond to changes in climate by adjusting management in ways that harness benefits or reduce anticipated effect.
