Sum of Midpoints 

 Dominance Threshold Number Equals 50% x Sum of Midpoints 



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 - 96-100% (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 midpoints 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 asterisk.
