Bats comprise one-fifth of all mammal species and are critically important to maintaining healthy ecosystems yet are often misunderstood by the public. Bats are ecosystem indicators, meaning that their presence or absence implies the conditions of their habitat. Importantly, we can use bats as a proxy for determining the status of recovery of habitats following natural disasters like fire. While wildfires are a natural part of California’s landscape, the fire season in California and across the West starts earlier and ends later each year, with climate change considered to be the key driver of this trend. To understand how wildfire is affecting the diversity and abundance of bats, I conducted echolocation surveys in 2021-2022 within the SQF Complex, which burned in Sequoia National Forest and adjacent areas in August 2020. The goal of the study was to determine how the number of bat species and composition of bat species in a habitat change in response to the degree of fire severity. This information is crucial to understanding how bats are adapting to fires, encouraging appropriate habitat management and conservation efforts of an order facing numerous threats.
