■'•Summer season was from June 



15 to September 2, 



inclusive . 



Fall 



season was from 



September 9 to November 11, inclusive. In general, the end of the season is determined 

 by the onset of winter so that the November 11 date was known only after the season 

 actually closed. The hunting season for mountain goats opened on September 15, and 

 about 100 permits were issued. Most of the area opened for either sex elk hunting 

 beginning September 21; the extreme northern part opened on October 27. Deer hunting 

 opened October 27. Fishing was permitted during the entire study period. 

 ^ Sampling intensity in percent is shown in parentheses. 



Sample Selection 



Sample units were randomly selected within the constraints of feasible work 

 scheduling. On weekdays, one location was sampled. On weekends and holidays, two 

 locations were sampled. We selected 110 two-day sampling units (table 1) : 56 units 

 during the summer and 54 in the fall. First, dates were chosen randomly for each 

 stratum, and then a trail location was randomly chosen for' each date. Sample dates 

 were chosen first for stratum 1, then for stratum 2, and so on from the remaining 

 available workdays.
