Snag Forest Habitat Protection

The Wild Nature Institute's goal is to ensure that research on forest fire, insect outbreaks, and wildlife is translated into improved forest-protection policies and effective forest-management activities that conserve snag forests, also called complex early seral forest:  a critical, scarce, and misunderstood wildlife habitat.

A disconnect exists   between the science and public opinion about impacts of high-severity fire and insect epidemics, with the public mistakenly believing that these disturbances destroy wildlife habitat. This false assumption that fire and insects are destructive to wildlife is providing the underlying basis for increased logging. Yet logging—including thinning in the name of fire reduction, and salvage logging of burned trees—is actually the greatest threat to the forest ecosystem.

Forest fires, insect outbreaks, and other disturbances are natural elements of healthy, dynamic forest ecosystems in the western United States, and have been for millennia. Exciting scientific research has demonstrated that many species of plants and animals increase in abundance following high-severity forest fire and insect infestations. Research conducted by Wild Nature Institute scientists and The Institute for Bird Populations found that California Spotted Owls--a species that was previously assumed to be harmed by high-severity fire--prefer to forage for their small-mammal prey in intensely burned forests when that habitat is available. Predatory woodpeckers are strongly dependent upon disturbances: Black-backed Woodpeckers are the most specialized of all birds to eat wood-boring beetle larvae in intensely burned forests and are rarely encountered in unburned areas, and American Three-toed Woodpeckers are far more abundant in forests with spruce beetle epidemics than other areas. In turn, beetle populations can be regulated by these predatory woodpeckers. Far from being a threat, high-severity fire and insect outbreaks actually provide great benefits to forests and many wildlife species.

Western forests have evolved to naturally thin their trees when the forest becomes thick, through forest fires, insects, or disease. These processes cull the weak and make room for the continued growth of stronger trees. Fallen dead trees are recycled in the forest nutrient cycle to feed the soil. After forest fire or beetle outbreaks, green forest naturally regenerates without the need for human intervention. Tree seedlings sprout and grow, and nitrogen-fixing shrubs and forbs replenish the soil and curb erosion. In the meantime, standing dead trees (snags) and logs provide critical shelter for many types of animals, from woodpeckers and bluebirds to flying squirrels and Pacific fishers.

Wild Nature Institute scientists conduct targeted studies of forest fire and insect effects on Spotted Owls, Black-backed Woodpeckers, and other forest wildlife. These studies contribute to our understanding of the important role of natural disturbance in forests and counter false reasons for increased logging. Our scientists have extensive experience with outreach to the public, media, policymakers, conservation organizations, and other scientists. We apply this experience to ensure that the results of our research and related studies on the ecological importance of natural disturbances reach a broader audience.
