Actual Total Canopy: Obtained by summing the percent cover of all quadrats on the transect.
Average Quadrat Canopy Cover: Obtained by dividing the total canopy by the total number of quadrats sampled on the transect.
Frequency: Obtained by dividing the number of occurrences of a plant species (the number of quadrats in which a plant species was observed) by the total number of quadrats sampled along the transect.
Species composition: Obtained by dividing the percent canopy cover of each plant species by the total canopy cover of all plant species.
