Wildfires are a natural part of both the Sierra Nevada and Great Basin ecosystems. Many plants and animals are adapted to survive and thrive with regular wildfires. However, due to human impacts like climate change, fire suppression, invasive species, and outdoor recreation, the fire regimes (intensity and frequency of fires) of these areas have changed. Communities in and near wildlands must prepare for more frequent and intense fires and monitor local fires and fire regulations in their area.
Fire maps show current and contained wildfires in a given area, as well as information for residents in those areas. Visit these sites regularly during wildfire season to receive accurate, up-to-date information.

Along with other natural disasters, wildfires pose a threat for asbestos exposure as they move into cities and residential neighborhoods with structures built before 1980, when asbestos was commonly used in construction. Breathing in this toxic fiber can cause a rare but serious disease called mesothelioma. Due to its long latency period, many patients are not diagnosed until much later in life. Symptoms include shortness of breath, dry cough, and chest pain. If your home or neighborhood was built before 1980, you are at higher risk of asbestos exposure from a wildfire. But keep in mind that wind can blow smoke, soot and ash for miles, potentially exposing residents in nearby communities to asbestos fibers mixed into these particles.
Only a N-100 or P-100 respirator will properly filter out tiny asbestos fibers that may be mixed with smoke and ash. Here are some other helpful tips before, during, and after a wildfire:
