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.
