Healthy forests are beneficial for people and wildlife. A healthy forest features a patchwork of open and densely forested spaces, contains a mix of trees and plants that reach different heights and sizes, allows sunshine and precipitation to reach the forest floor, and has large rocks, stumps and logs that provide hiding places and homes for wildlife. When forests are healthy, they produce enough food, water and shelter to support local wildlife, clean the air, reduce erosion into nearby streams and lakes, and are less susceptible to destructive wildfires. 

While wildfires are inevitable, not all fire is harmful to forests. Low-intensity fires can naturally “clean” and thin the forest by removing flammable and thick vegetation on the forest floor. The result is improved habitat for wildlife, healthier soil and new growth of native plants. It also helps reduce the risk of large-scale high-severity fires that burn through the forest, from the floor to the canopy, with intense heat. High-severity fires across large landscapes can be devastating for wildlife, habitat and surrounding communities.  

Alongside partners, the U.S. Fish and Wildlife Service is working under the authority of the Endangered Species act to support activities that improve the overall health of the nation’s forests, reduce the risk of large-scale high-severity fires and protect important habitat for forest-dwelling plants and animals.

When you close your eyes and think of a healthy forest, you may picture one that’s thick with trees. But a healthy forest is complex, just like the plant and animal species that live there.

When wildfires erupt, animals do their best to move out of the direct path of the flames while staying close to home if they can find safe refuge. But when a high-severity fire burns across a large landscape, it moves fast and climbs through the tree canopy. Wildlife has a more challenging time...

Fires have swept through large portions of habitat used by the southern Sierra Nevada distinct population segment of fisher over the past several years. By examining how fisher are using post-burn forest, the Service hopes to learn more about the needs and habits of this elusive endangered species.
