Restoring An Iconic Joshua Tree Forest: Natural Recovery, Restoration Success, And Soil Microhabitats On A Desert Burn Area, Riley Scaff

Pitzer Senior Theses

Wildfires are a novel disturbance type in the Mojave Desert, but have been increasing in size and frequency since the 1970s due to the proliferation of invasive grasses. Burned areas are more susceptible to invasion, which can lead to the establishment of a grass-fire cycle. For this reason, restoration is often necessary to facilitate natural plant community recovery, but the extreme desert climate makes returning native vegetation to burn areas challenging. Planting in nutrient-rich soil microhabitats could be a helpful tool to improve revegetation success, but has yet to be tested. This study surveyed natural postfire recruitment across two seasons …
