After performing the three surveys, line intersect, strip intersect, and quadrat, the resulting data reflected little difference in the ultimate results. During an initial and general visual survey the team was impressed with the beauty and number of pine trees.This impression conflicted with the results. After reflection, we agreed that the data was a true reflection of the environment. In a single hectare, at one meter intervals, there are ten thousand data points. As the top of the tree or shrub would be off the ground and therefore not considered in the survey, it does seem realistic that our data points, at ground level, would not fall at the base of trees or shrubs.

After examining the spread of the trees and shrubs it becomes much more logical to predict that natural litter would be present in the majority of the readings. This natural litter and the shade of the trees and shrubs would also tend to suppress most types of ground cover. In future surveys it would be advisable to use a variety of different types of surveys or possibly alter the pattern for data collection. A survey of the perimeter or random walk pattern might lead to more conclusive results.
