Meta- data :Dbh of the mother tree ( cm): Is the diameter size of the tree that was measured by a measurement tape. The diameter was measured at our chest hight in specific. Canopy coverage of the mother tree ( %): a sequel was made in our hand, and we looked up to the sleeves and measured the percentage of the sleeves Dbh sapling (cm ) : Is the diameter size of the tree that was measured by a measurement tape. The diameter was measured at our chest hight in specific. <br><br>Site description : the site called the Danby grass / woodlot… it was sunny day and the sky was clear . Temperature was around 26 C and the work was done between 2:30- 5 pm on Wednesday the 21 of September. <br>Methods: we walked to the field and measured 10 trees and we identify them as a mother tree. Tress that were twice taller our hight and more than 5 cm in diameter was counted as the mother tree. The sapling tree was any other tree that was next to the mother tree and not taller than 200 cm. the Dbh was the measurement of the diameter at our chest hight and was measured with a measurement tape. In the other hand, the % canopy coverage of the mother tree was measured by making a square in our hand and look at the sleeves and see how much is the coverage percent comparing to that square. Hypothesis : hypothesis : it was hypothesis that the size of the diameter of the mother tree and the more canopy coverage percent are inversely proportion to the dbh of the sapling because the mother will take most of the nutrition available foe example amount of water and sun light <br>Prediction : The bigger the size of the diameter of the mother tree and the more canopy coverage percent, the smaller the dbh of the sapling.
