Point-Centered-Quarter sampling of the canopy layer (trees with a diameter at breast height of 10 cm or greater) in two forests, Frank and Phyllis Yuhas Woods and Duning Woods Nature Preserve, in East-Central Indiana was performed for this thesis. This method allows for the calculation of frequency, basal area, density and importance values of each tree species within the woods. These statistics will be reported for each study site. They will be used to determine the presence, distribution, and abundance of plant life, as well as used to place each forest within a classification system that allows for comparisons between woodlands. This study encompasses three habitats, a floodplain woods and upland woods at Yuhas, and a ravine forest at During. It also speculates on several possible mechanisms for, and consequences of, ecological change within the two woodlands. These studies provide baseline information of the two woods in the hopes that the data will aid future management decisions.
