1 Cover classes (midpoints): T<1% (none); 1 = 1-5% (3.0); 2 = 6-15% (10.5); 3 = 16-25% (20.5); 4 = 26-50% 

 (38.0); 5-51 -75% (63.0); 6 = 76-95% (85.5); 7 = 96-1 00% (98.0). 



2 To determine the dominants, first rank the species by their midpoints. Then cumulatively sum the midpoints 

 of the ranked species until 50% of the total for all species mkJpoints is immediately exceeded. All species 

 contributing to that cumulative total (the dominance threshold number) plus any additional species having 

 20% of the total midpoint value should be considered dominants and marked with an astensk.
