Forest management practices influence habitat for birds by altering stand structure. Stand structure may be a proximate factor in habitat selection by birds, indicating the availability of an ultimate factor: food. Information on the influence of silvicultural practices on food resources for birds would be useful to ecosystem managers.

However, even basic knowledge of functional relationships among plants, insects, and birds is extremely limited. The purpose of this study is to focus on the role of understory vegetation, and determine how it contributes to diversity of arthropods and birds in conifer-dominated forests.

	All objectives of this study have been accomplished. Joan Hagar received her doctorate from the Department of Forest Science at Oregon State University. A downloadable version of her dissertation titled "Functional Relationships among Songbirds, Arthropods, and Understory vegetation in Douglas-fir Forests, Western Oregon" is available online or may be requested from the CFER program office.
