Summary

Snags provide critical habitat for nearly one-third of wildlife species in forests of the Pacific Northwest, so historic declines in snags are thought to have had a strong impact on biodiversity. Resource managers often create snags to mitigate the scarcity of snags within managed forests, but information regarding the function and structure of created snags across long time periods (>20 years) is absent from the literature. Using snags that were created by topping mature Douglas-fir trees (Pseudotsuga menziesii) as part of the OSU College of Forestry Integrated Research Project, we measured characteristics of 731 snags and quantified foraging and breeding use of snags by birds 25-27 years after their creation. We also examined whether [...]

Purpose

Data were collected to assess the changes in characteristics of Douglas-fir snags after 25 years and the usefulness of these structures to cavity-nesting birds. Data were also collected to assess the impact of different regeneration treatments and snag configurations on both characteristics and use by birds.
