Sagebrush steppe ecosystems evolved with periodic fire, but this relationship is altered across much of the arid west by invasive species, land use change, overgrazing, and climate change. While understanding the short-term impacts of fire on these systems, little is known about the longer-term trajectory of recovery. To fill this gap in knowledge, we investigated the long term influences of fire in relatively intact Wyoming, basin, mountain, and low sagebrush steppe ecosystems on fuel loads, potential fire behavior, and plant community characteristics. In this webinar, we will describe 1) The long-term (17-26 year) post-fire accumulation in fuel loads and resultant potential fire behavior where historical prefire and immediate postfire data exists in Wyoming and Basin big sagebrush communities; 2) Fuel loads accumulation and structure along a time-since-fire chronosequence in Wyoming, mountain, and low sagebrush ecosystems; 3) The fuels and reburn potential in once and twice burned Basin big sagebrush plant communities; 4 Plant community change 17 years post fire in Wyoming big sagebrush ecosystems.
