Abstract
This study aimed to estimate a taper equation for eucalyptus trees growing in Nineveh Governorate, it is used in forest inventory or management planning systems, giving information about the diameter at any point along the main stem of the tree. Data were collected from three naturally growing trees for diameter at breast height, total height, and diameter at different levels, starting from 0.5 m above ground level, with distances of half a meter along the main stem, using computer and regression methods. different. Linear and non-linear. In the preparation of the taper equation, as well as the use of statistical measures, namely, the coefficient of determination R2, the standard error attributed to the S.E rate, in the test of the best taper equation, and through the comparison between equations through statistical measures, we were able to obtain the following taper equation: d = 14.2299 * hi -0.1873 And by taking the integration of the taper equation, we got an equation for estimating the size of eucalyptus trees, which is:V1 = 0.02542(hi)0.6254.
