资源简介：
Location: York University's woodlot Target adult silver maple trees that are twice our height were randomly chosen and their diameters were measured at breast height. A radius of 10m was measured using a transect from the target tree and each tree that was in that radius was counted. The sunlight percentage was estimated by seeing how much sky is shown throught the tree's canopy. A frame that was held up to the sky with our back facing the tree. The next target silver maple tree was chosen by walking 5m away from the previous radius. A total of 35 target trees were measured and radius counted.
