Title: Fire and Invasive Annual Grasses in Western Ecosystems

Project Proposal Abstract: Annual grasses have invaded shrub and forest ecosystems in western North America and are linked to changes in both ecosystem structure and fhnction and in some cases have altered fire regimes. This has occurred over vast expanses of public lands in the Great Basin and the Mojave Desert, and is a threat to lower elevation yellow pine forests. We hypothesize that fire has the potential for contributing the most to annual grass invasion in low nutrient soils, where postfire increases in theft availability are more effectively exploited by invasive grasses than by the native flora. Soil nutrient changes can vary widely depending on soil properties and the amount and duration of soil heating. In forested ecosystems such impacts of fire on soil nutrients and light solar radiation are potentially more profound now than under historic conditions because of unnaturally high fuel loads. We propose to investigate the interactions between fire and soil nutrients over three ecosystems cunently dominated or threatened by invasive annual grasses in western North America -- Great Basin shrubland, Mojave Desert scrub and Sierra Nevada yellow pine forest. Common factors driving the fire/annual grass cycle in these ecosystems will lead to generalizations widely applicable beyond the ecosystems under study. In addition, each of these systems has unique features that contribute to the dominance of invasive annual grasses, and elucidation of these will contribute to a broader understanding of the problem. We will use intensive field manipulations at representative sites in these three regions that will couple burning, nutrients, fiuels and light treatments. In addition, extensive surveys will be conducted across these regions to assess the soil nutrient status associated with invaded and non- invaded sites. These field studies will be coupled with laboratory studies to examine in detail the relationship between soil heating and nutrient availability for invasive grasses. With this information, managers could determine in advance if habitats are naturally vulnerable or resistant to invasions, enabling limited resources to be more effectively deployed both during and after fires. Fire prescriptions could be designed to avoid creating conditions susceptible to invasion, plus, restoration techniques could be better targeted, saving both time and money.
