The Park Fire, California’s fifth-largest wildfire, is endangering the habitats of the spring-run Chinook salmon, an already threatened species. This fire has invaded the Mill and Deer Creek watersheds in Tehama County, crucial areas for salmon spawning and for young fish to get ready for their ocean journey. Officials from both federal and state levels are concerned that if the fire reaches higher elevations, it will significantly damage the already small salmon population. The firefighting efforts, though necessary, pose a major risk to salmon habitats. Fire retardants are harmful to fish, and heavy rains could wash ash, chemicals, and sediment into the creeks, suffocating salmon eggs and young fish and causing harmful microbial blooms. Experts note that salmon numbers have already been declining due to dam construction and water diversion, worsening their situation. Conservation programs, such as a hatchery initiative by wildlife agencies, aim to protect the species, but the Park Fire makes these efforts even more urgent.
