We determined gap size, gap density and total gap area within all treatment units except the clearcut.
Transect lines were established 50 m apart tapproximately 3600 m of line) on maps of each treatmentunit. From these lines. approximately 2000 m of transect line was randomly selected. The total length of fine in canopy gap and forest matrix was
recorded. The size of each canopy gap encountered was determined using methods described by Runkle
