Invasive species in forests and rangelands of the US: A synthesis

View synthesis.

Invasive Species in Forests and Rangelands of the United States is a sector-wide scientific assessment of the current state of invasive species science and research in the United States. Leading experts on invasive pests, climate change, social sciences, and forest and rangeland management contributed to highlighting the science and identifying knowledge gaps on a diverse array of topics related to invasive species. Stakeholders from nongovernmental organizations, academic institutions, professional organizations, private corporations, and state and federal agencies representing public, private, and tribal interests also provided input to the assessment. Input from these stakeholders helped to frame the subject matter content and management options presented in this report, ensuring relevance for decision-makers and resource managers.

Invasive species, native seeds, and grasses

Webinar recording.

Disturbance events, such as overgrazing and the catastrophic fires, in our shrub steppe landscape can kick-start a negative feedback loop with invasion of noxious weeds. These invasive species can have a direct effect on services and ecological benefits provided by the shrug steppe landscape. Learn what we can do to minimize the spread of invasive plant species and how native seeds and grasses can be used to restore this brittle system.

Invasive Annual Grass Workshop

Workshop information.

Invasive annual grasses threaten millions of acres of sagebrush rangelands across the west. This two day workshop hosted by the Harney County Wildfire Collaborative and Oregon SageCon Partnership will explore the barriers and opportunities for addressing invasive annual grasses in Oregon and beyond the state. In this workshop some of the most pressing issues related to invasive annual grass management will be discussed, including the connection between invasive annual grasses and wildfire and what can be done to better address this threat.

VIRTUAL Workshop Dates & Agenda
Monday, December 14, 12:30-4:30pm: Defend the Core—Keeping the Good, Good

  • Hard truths of invasive annual grasses
  • Stopping the Spread
  • Supersizing Suppression Success
  • Reducing Wildfire Risk
  • Ratcheting Up Resiliency

Tuesday, December 15, 8:30am-12:30pm: Grow the Core—Restoring At-Risk and Converted Lands

  • Managing Invasive Annual Grasses
  • Innovative Restoration
  • Prioritizing Limited Resources & Sustaining Long-term Investment
  • Where Do We Go From Here

Wildfire and invasives in sagebrush: current and future management challenges – A gap report update

View report.

This Gap Report Update is the latest addition to the list of valuable products of the Working Group designed to help identify the challenges (gaps) and offer ideas to address those challenges. The Gap Report Update has something for every level, public and private, to consider helping address the fire and invasive threat. It is our hope that the leaders of the various state and federal agencies will review the recommendations in the report and determine if there are things they can affect directly to address the gaps. It took a multi-agency, multi-discipline Working Group to identify the problems and provide possible solutions to these conservation and management challenges, it will certainly take a broad-based coalition of agencies, and public and private groups working together to ensure a healthy Sagebrush Biome is available for generations to come.

Top 50 invasive species in the West from the Western Governors Association

View brief.

The Western Governors’ Association (WGA) has addressed this need by surveying invasive species coordinators in WGA member states and territories Top 50 Invasive Species in the West to develop the “Top 50 Invasive Species in the West.” The compilation of terrestrial and aquatic invasive species includes highly-publicized examples such as cheatgrass, Quagga Mussels, tamarisk and the Emerald Ash Borer. The list also encompasses less well known, but still impactful, examples such as leafy spurge, Red shiner, Russian knapweed, and Golden algae.
