Simpson's Index of Diversity For A Forest Community

This worksheet will provide additional practie determining Simpsons Index of Diversity for a forest community. Sort the leaves from the pile below right into species groupings (use key below to help with identification). One leaf was taken from each tree along the forest transect.

White Oak         Red Maple         Tulip Tree         Sassafras         Hickory         White Pine         Redbud         Beech         Cherry

Count Number of Trees (n) and Calculate n(n-1) And Enter Below

species number n(n-1)
White Oak
Red Maple
Tulip tree
White Pine
T = Σn(n-1) =

for an 89% chance in this forest that two trees selected randomly will be of different species, a very high degree of species diversity based on evaluating species richness and species evenness
