Five birch trees were selected, however all of their girth lengths were not around the same size. Birch tree number 1 and number 3 have only 3 centimeters separating their girth lengths and birch tree number 2 and 5 are both around 120 centimeters wide (table 1). Birch tree number 4 is the most odd one out of the five as its girth length is only 108 centimeters. The wide range between the density of the trees creates a lack of accuracy and the end results might not be the same as they could be if all the trees had a more consistent girth length. The5010areas on the trees were then located and lichen were observed and identified. The direction of the area was pointed at, the east, south and west, did not provide a wide range of different lichen, hence the whole tree has had access to
