Snags, large down logs, and big decadent trees provide food and shelter to more than 40 percent of wildlife species in Pacific Northwest forests. They are important structures for cavity-dependent birds and small mammals, food sources for woodpeckers and other foragers, and  slowly release nutrients into the ecosystem with the help of decomposer critters. 

And as the Bisers worked on restoring the hydrology of the forest, something amazing happened: beavers moved in, and eagerly set to work restoring the hydrology on their own.
