| dc.description.abstract | The research aim to estimate the basal area of Pinus merkusii combired comprises measurement by
aerial photograph with scale of 1 : 20.000 field and to measurement field. The stand parameters
measured are the number of the trees per hectare (N), the tree height (H) and crown diameter (D).
Whereas, estimation of the stand basal area was based on the measurement of the stem diameter in the
permanent plots. The result of the regression analysis showed that the based area of the Pinus merkusii
stand (lbds) had correlation with the number of the trees per hectare (N), the tree height (H) and crown
diameter (D), the regression is as follows: Basal areas or tree densities of compartement 100 and 102
have been optimum . Therefore, resin production compartement 100 and 102 is higher than compartement
101 having lower basal are or tree density. It is for those reasons, the compartement 101 needs action to
cut the suppressed trees to make optimum basal area. | en_US |
