Maple Tree Adult and Sapling Data collected at York University

Data was collected from the Danby Woods forest at York University's Keele campus. Researchers analyzed 10 Maple trees and their nearest sapling and recorded 4 variables which included dbh, % canopy coverage, distance to sapling, and dbh of sapling. Diameter at breast height (dbh) and sapling dbh ware measured in cm using a measuring tape and were recorded to the nearest 0.1 cm. Canopy coverage was estimated using hands to create a small square in the sky from which the percent coverage could be estimated. Finally, distance to the nearest sapling was measured in metres from the centre of the adult trunk to the sapling trunk. Saplings were defined as trees that were no higher than approximetly double the height of an average student.
