It is presumed that studies presenting only herbaceous plant cover <br />eliminated any cover due to woody taxa. Studies that present total plant cover include both herbaceous and woody plant <br />cover (typically below a level of about 1.5 meters). In these cases, herbaceous cover can be segregated from woody <br />cover (with the exception of Harner's 1985 data set). Hamer's data were reported in a manner that does not allow <br />isolation of 1st hit vs. 2nd hit data. Discussion with Harner in 2007 confirmed that it is not possible to separate these two <br />data components without the raw data sheets which have long since been recycled. <br />Revision Date: 3/30/07 <br />Revision No.: PR-02 <br />
