Fire and Invasive Annual Grasses in Western Ecosystem
A project funded by the Joint
Fire Science Program
Field surveys are being used to evaluate correlations between soil characteristics
and postfire dominance by invasive annual grasses at a wide range of low soil
nutrient sites across western North America.
Soil samples are being collected at high and low carbonate sites and/or high
and low fertility sites in each region. Soils are being sent to Brigham
Young University Soil Laboratory
to be analyzed for available nutrients.
Objectives
- Identify soil characteristics that are associated with high dominance of invasive annual grasses after fire over a wide range of ecosystems
- Compare patterns of postfire dominance among a range of invasive
annual plant species
