Over the past several years the number and size of invasive grass induced wildland fires have grown at an alarming rate. It is now well established that there is a feedback mechanism between invasive species and fire. For example, in the West, this is primarily a function of fire-tolerant invasive grasses spreading into landscapes which were previously much less prone to burning; where native plants did not provide a continuous bed of fine fuels but non-natives do. Significant effort is being devoted to looking at the inter-relation of invasive species and wildland fire, including vegetation and weed management, post-fire recovery, and pinpointing high risk hotspots.
