Abstract Runkle, James R. 1992. Guidelines and sample protocol for sampling forest gaps. Gen.Tech.Rep.PNW-GTR-283. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 44 p. Comparative studies of forest structure and dynamics require standardized methods. A protocol for sampling forest canopy gaps is presented. Methods used in published gap studies are reviewed. The sample protocol will be useful in developing a broader understanding of forest structure and dynamics through comparative studies across different forest ecosystems.
