Response of forest avifauna to silvicultural
treatments in west-central Idaho

Silviculture is the art and science of controlling forest establishment, composition, stocking rate, and growth, and silvicultural practices include a tremendous array of techniques that go far beyond simply removing trees. One such technique, designed to boost the production of plant biomass and remove competition from unwanted plant species, is the application of fertilizer and herbicide, respectively, to forest stands. In addition to promoting tree growth, fertilization treatments can also create short-term (1-5 years) increases in the density and cover of understory vegetation, such as shrubs, grasses, and other herbaceous plants. These changes in understory structure and composition could potentially affect forest birds, especially those species that nest and forage on the ground or in the understory. To better understand these potential responses, SEI-Idaho, in partnership with Boise Cascade Corporation, is conducting a new study to document the response of avian nesting success to these silvicultural treatments.
