Lab 2- Woodlot Data set 3

Metadata First Tree D.B.H (cm)- D.B.H (Diameter at breast height) was approximately 130cm from the ground, which was the observer’s breast height, and was measured in centimeters. The diameter of the tree trunk was measured at this height with the use of transect tape. It was horizontally allied along the trunk (diameter) of the tree and the value was recorded. The D.B.H was measured in regards to the larger tree; the tree that was visually observed as large contained a wider trunk, was bigger and taller). Conditions: A number between 0-2 was given to each tree that was observed according to its physical appearance and/or condition. 0= Tree is dead, no leaves/brown dead leaves, peeling bark. 1= The tree is living with few leaves, not a very abundant canopy. 3= Tree has a large green canopy, with healthy leaves and bark. This was determined according to the observer’s discretion on each tree. Distance between first and second tree (cm):The distance between the first observed tree and the second observed tree was measured in centimeters by transect tape. The distance was measured from each trees’ trunk. These trees were not a selective type, the distance was measured between trees with close locality. Hypothesis It is hypothesized that the larger the diameter of the tree and the greater the distance between the first and the second tree, the tree will be in a better condition due to the fact that it has less surrounding completion and has its own personal space. With this, the tree can utilize the resources around it for itself only. Prediction 1: The greater the D.B.H of the first tree, the further the second tree is. Prediction 2: The further the second tree is, the better conditions of the first tree. Site Description: Danby woodlot, York University Campus. Data was collected at the time period of 14:30-17:30, at the temperature of 28°C, sunny, hot, humid weather. Abundant vegetation of leaves, flowers, grass, weeds and other plants.
