Third group member was given the responsibility of counting all the trees within that quadrant. Once the transects were set 2 group members marked all the buck thorns and maple trees in that quadrant with rubber bands. Fourth group member was asked to write down all the observations on the data table.

DBH of every buckthorn tree and the maple tree was measured and was written down in the observation table. First quadrant was set up almost at the edge of the Danby Woodlot and consecutive quadrant was set up diagonally to the first one. Due to lack of time only 3 quadrants were completed on Day 1 and a tree was marked with a yellow tape and a picture was taken to determine where set up 4th quadrant next week.

Next week, Wednesday, the experiment was continued; tree marked with yellow tape was found and a 4th quadrant was set up. A total of 5 quadrants were observed and the number of buckthorns and maple trees were recorded in each quadrant
