July and August webinars

Regional mapping of herbaceous annual cover in the Great Basin - July 26, 2017

Speakers: Bruce Wylie and Stephen Boyte, U.S. Geological Survey

In this webinar, Bruce Wylie and Stephen Boyte with the U.S. Geological Survey discussed their recent work mapping herbaceous annual vegetation across regions in the Great Basin. The speakers also discussed data access, selected journal publications and future plans during the presentation.

Using weed-suppressive bacteria to control invasive annuals - August 28, 2017


  • Matt Germino, U.S. Geological Survey and Great Basin LCC
  • David Pyke, U.S. Geological Survey
  • Richard Lee, Bureau of Land Management
  • Mike Gregg, U.S. Fish and Wildlife Service

  • Brynne Lazarus, U.S. Geological Survey

Cheatgrass (Bromus tectorum) and medusahead (Taeniatherum caput-medusae) invasions pose a serious threat to Great Basin ecosystems. Managers and scientists are hopeful that strains of the bacterium Pseudomonas fluorescens that have been selected for their weed-suppressive properties in laboratory, greenhouse and wheat field trials will also be able to selectively inhibit root growth of annual weeds in more complex rangeland ecosystems. In this one hour "lightning session" webinar, six speakers provided an overview of the promise and uncertainty surrounding weed-suppressive bacteria use in Great Basin rangelands and the efforts currently underway to better characterize its effectiveness.
