The main purpose of this exercise is to see if College Woods Natural Area is experiencing succession, and to observe and document the tree community structure. Other purposes of this exercise are to examine College Woods and measure the densities of different species of trees as well as diameters of stems, and use these measurements to determine if the varying measurements lead to varying information about this tree community. Another purpose is to determine all species present, as well as the abundance of each species. We will also analyze the size structures of the trees to predict future change in College Woods Natural Area.2.a.The extent of the estimation of absolute density from absolute dominance is variable when looking at figures two and three.Figure two would not be a good example of a good estimator of absolute density estimated from absolute dominance. The R-squared value, which tells how close the measurements are to the resulting fit line, is equal to 0.027 (where as an R-squared value of 1.0 equals a perfect fit). This shows that there is a very small relationship between absolute density of the Hemlock and absolute dominance of the Hemlock.Figure three would be a good example of an estimator of absolute density from absolute dominance. The R-squared value is equal to 0.609, which is significantly higher then that in figure 2 (0.027). The higher the R-squared value, the stringer the relationship, in this case, of absolute density of Black Birch and the absolute dominance of Black Birch.The fact that in one case the ability to estimate absolute density from absolute dominance is great (Birch), and in the other is low (Hemlock), suggests that this is not a reliable method of estimating. There must be alternate factors to take into consideration to estimate absolute density.As seen in figures one and four, the estimation of absolute density from relative density, has more merit then that of absolute density from absolute do...
