For Sandstone prairies BUL study sites and Southeast prairies BUL study sites, we calculated descriptive statistics of the following variables: relative abundance (mean [+ or -] SE individuals per point) of each individual species; relative abundance of all individuals of all species combined; and relative species richness (mean [+ or -] SE species per point).
For all analyses, values of these variables at study sites in the Sandstone prairies BUL were compared to those in the Southeast prairies BUL.
A total of 1,108 individuals representing 41 species were detected during the two years of study: 311 individuals representing 25 species at study sites in the Sandstone Prairies BUL and 797 individuals representing 38 species at study sites in the Southeast Prairies BUL (Table 2).
We did not quantify the extent or amount of woody vegetation associated with our study sites but it is possible the higher relative species richness in the Sandstone Prairies BUL study sites reflects a greater amount of woody vegetation associated with those sites.
