inclusion in the species list. Site parameters (slope, aspect. 

 elevation, topographic position and slope configuration) were recorded 

 for each transect. 



A habitat type map (1" = 2000') was prepared of the OEA Research study 

 area. 



SAWYER SURVEY (Extracted From Sawyer, 1984) 



Habitat type mapping was extended to an area south of German Gulch. 

 Additional information was obtained in forested stands using two 

 methods, Bitterlich's Variable Radius Method and the Point-Centered 

 Quarter Method, as outlined by Mueller-Dombois and Ellenberg (1974). 

 The Point-Centered Quarter Method was used to calculate tree density 

 and basal area values for five sites (twenty points per site). The 

 Bitterlich method was usee to calculate a second value for basal area 

 with an average cf 22.4 sample points per site (ranging frorri 13 to 30 

 sample points per site). A Cruise Angle gauge (basal area factor of 

 20) was used in sampling the sites. Timber volumes were obtained as 

 estimates from personal communication with Davis (1983). Stand data 

 based on the point-centered quarter method were generated for trees 

 with dbh greater than four inches. 



Sawyer (1984) also summarized information on grazing for his study 

 area .
