Species Black Thorn was chosen because of simple identification through distinction of their bearing of small black berries. Criteria of an adult tree included the bearing of small black berries on multiple branches and taller than 5 metres. Tape measure was placed against adult Black Thorn trunk at breast height, and width of trunk was measured with tape measure. Black Thorn Canopy Coverage was determined by viewing the above canopy through a square formed by the index finger and thumb of both hands. Distance to nearest sapling tree was measured with measuring tape; criteria of sapling tree included not being over 3 metres tall. Tape measure was placed against trunk at breast height, and width of sapling tree was measured with tape measure.
