1980), were quantified at each station, May 1980 (Table 1). Estimates of 

 cover by rocks, logs, leaves, canopy, and midstory followed methods 

 described by James and Shugart (1971). Understory vegetation charac- 

 teristics (8) were quantified on 4 m 2 circular plots 2 m away from each 

 station along the contour in January and April 1980. A modified 

 Aldous method was used similar to that described by Murphy and 

 Noble (1972). Percent cover and stem density were determined for each
