Fire and Invasive Annual Grasses in Western EcosystemA project funded by the Joint
Fire Science Program
A combination of intensive field experiments, extensive field surveys,
laboratory experiments, and seedbank analyses are being used to evaluate
the interrelationships between fire, soil, nutrient availability and invasive
grass dominance. These three components complement each other and will
be used to develop a comprehensive model that relates mechanisms of annual
grass invasion after fire to field conditions and potential postfire mitigation
techniques.
