### Structural and Diversity Parameters of Pine Stands from Degraded Lands  
Analyzing the correlation between DBH and Dc (Figures 2a-d, 3a-d, 4a,b and 5a,b), showed that as the diameter increases, the crown length increases, according to a linear regression. The same tendency is expected in the case of the correlation between diameter and the crown's relative length (Lc%), showing the same hypothesis (Figures 6a,b, 7a,b, 8a-c and 9a,b). The obtained correlation coefficients showed a medium to strong correlation between the considered local variables of crown diameter (Dc) x basal diameter (DBH), \begin{table}
