Managing invasive annual grasses, annually: A case for more case studies

• •

  The continued expansion of invasive annual grasses is a complex ecosystem management problem requiring a shift in focus from a discrete, single treatment approach to one of adaptive management with sustained investment.

• •

  Four case studies shared at the 2020 Invasive Annual Grass workshop provide lessons learned and opportunities to advance future management efforts to inform the direction for new science.

• •

  Tackling the complex problem of invasive annual grass management will require an expansion of science-based case studies of real-world management efforts, strong science and management partnerships, and a platform for continuous learning and communication, such as a comprehensive database to document management outcomes along with Open Access journals that allow publishing of negative and null outcomes.

• •

  Managers can use existing tools such as the Land Treatment Digital Library, Land Treatment Exploration Tool, and the Rangeland Analysis Platform to understand the efficacy of invasive annual grass treatments under a variety of site and environmental conditions.
