Data of Several Species of Trees Collected in York University's Woodlot

The data obtained was from the woodlots of York University in Toronto. It was a forested area on the outskirts of the university and there was a lot of green canopy. There were different species of trees were present for observation and data recording. The data was collected in pairs, one person recording the numbers and measurements, and the other using the tools in order to obtain the measurements. The tools used were transect measuring tapes and normal measuring tapes. The data was collected from 10 arbitrary trees from the edge to the centre of the woodlot. Walking in a straight line, every tree encountered that was twice the data recorder’s height was recorded. The dichotomous tree guide was used to compare and match the tree leaves according to its species. Data from the species of Sugar Maple, Red Oak, Black Cherry, Bass Wood, Red Pine and White Spruce were collected. The following variables recorded were the species of the tree, the diameter of the trunk, the distance from the previous tree and the condition of the tree itself, using numbers 0,1,and 2. Each tree was labelled one to ten in order to chronologically keep track of the data and recordings. The species of the tree (Sugar Maple, Red Oak, Black Cherry, Bass Wood, Red Pine and White Spruce) was obtained by matching the leaves to the dichotomous tree guide provided in the lab manual. The diameter was the measurement of the tree trunk at breast height, measured in centimetres using the normal measuring tape. The distance was recorded in feet and stated the length from the previous tree to the current one being recorded using the transect measuring tape. The condition of the tree was measured using numbers, 0 representing dead, 1 representing living & small canopy, and 2 representing living & large canopy.
