APPENDIX E 



SITE CHARACTERISTICS FOR EACH PLOT 



Both quantitative and categorical site characteristics are 

 presented. "RI" values are solar radiation indices at each plot 

 as determined using Frank and Lee (1966) . These indices equal 

 the ratio of the total annual potential isolation to the maximum 

 potential at the site. RI=.43 for all flat surfaces in the study 

 area. The code letters under "% Cover" are defined as follows: 



S = bare soil G = gravel 

 L = litter W = wood 

 BV = basal vegetation 



R = rock 

 M = moss 



Classes of categorical site characteristics are defined as 

 follows:
