METHODOLOGY Sampling area consisted of an area of 120m x 50m within site two and was bordered by a road on one side and a stream on another. Approximately 25% of our study area was sampled. Sampling equipment: 30m tape measure, compass, poles used to mark out sampling blocks. Six samples were taken using random numbers in the form of long narrow rectangular blocks. Each sample block had an area = 5m in width x the distance from the road to the stream. For each tree in a sampling block the below are recorded: 1. The tree species 2. The circumference at breast height. 3. The area of damage 4. Moss and lichen cover. Note: Damage was recorded only at a height of below two metres. SAMPLE SIZE Approximately 150 trees of 7 different species in a certain area. The bark area had been measured up to a height of 2m for each sampled tree and the area of damage up to the same height. Many trees in the sample were actually undamaged. ANALYSIS REQUIREMENT Whether is there any variation in the bark damage between the species of tree? I need to know what statistical tools can I use to embark on the data analysis and what techniques I should consider in the analysis? Is it necessary to calculate the sampling error?
