The sampling strategy that I chose to measure the density of black spruce at three different elevations is the point centred quarter technique. The hill that I chose to conduct this study on has an elevation of 220m. The three elevations that I chose to measure the density of black spruce is 20m, 110m, and 200m. The hill is not very steep and is very wide. I conducted the point centred quarter technique at 5 points at each elevation, 5 meters apart from each other. Each point was divided into quarters so I measured the distance of the closest black spruce tree to the centre point for each quarter and then took the average of the four distances. I didn’t realize how much labour it would take to measure the distances. At first I went out on my own to get these measurements, however I realized that it would be much more efficient if I had someone to help me out so I had to come back with more individuals to help out. The data that I collected wasn’t surprising since it supported my hypothesis so I will stick with this sampling strategy. I think that the point centred quarter technique is the most accurate for this study since it collects the average of the distances from for quarters compared to other methods such as the neighbour distance method.
