This experiment examines the relationship between adult trees and saplings – more specifically, tree diameter, distance, and canopy coverage. <b>Methods:</b> -The experiment took place on Tuesday, September 20, 2016 from approximately 3:00-5:00 pm in warm weather conditions. 10 adult trees were randomly sampled and measured in comparison to saplings on the York University Keele campus using measuring tape and transect measuring tape. -For each adult tree that was sampled, its DBH and extent of canopy coverage were determined, followed by its distance to the closest sapling and the sapling’s DBH. DBH was determined by wrapping measuring tape around the tree’s trunk while the distance between adult tree and sapling was determined using either the measuring tape or transect measuring tape, depending on the distance. -The data was recorded in a notebook and later copied onto an Excel sheet. The data on Excel would then be uploaded to Figshare. <b>Hypothesis: </b> -The length of an adult tree’s diameter will have a direct correlation on the sapling distribution and size around it. <b>Prediction: </b> -The DBH of sapling is always less than the DBH of adult trees around it. -The larger the DBH of adult trees, the higher the percentage of canopy coverage. -The larger the DBH of the adult tree, the greater the distance it is from its closest sapling. -The competition and scarcity of resources make the adult trees and saplings not be close to each other. <b>Meta-data:</b> -DBH (cm) = Diameter at Breast Height; the diameter of the truck at chest level for the adult tree. The data is quantitative and continuous. -Extent of canopy coverage = An estimated percentage of sunlight coverage by the leaves, looking straight up. The data is quantitative and continuous. -Distance to nearest sapling (cm) = The distance between the adult tree and the sapling, both of the same species. The data is quantitative and continuous. -DBH of sapling (cm) = Diameter at Breast Height; the diameter of the trunk at chest level for the sapling. The data is quantitative and continuous.
