Oct 14, 2021 · California Wildfire Effects on Biodiversity. Cow looking for Refuge. Almost all of California’s diverse ecosystems have either become fire-dependent or fire-adapted. Fire-dependent ecosystems need wildfire to maintain appropriate function and health. Meanwhile, fire-adapted ecosystems have evolved to survive wildfires.
The estimated economic cost of the 2018 California wildfires was US$27.7 billion in capital losses, US$32.2 billion in health costs, and US $88.6 billion in indirect losses (Wang et al. 2021). Smoke produced by such wildfires can severely impact human respi-ratory and cardiovascular health, contributing to increased.
