The total forest cover of Sri Lanka is estimated as 32% from the total land area. More than 50% of this area lies in the dry zone where the original forests have been cleared drastically.

Taper is the rate of change of diameter over a specific length along the tree stem. Taper varies not only by species, but also by dbh, tree height and other tree parameters. Taper is important for the foresters to predict the upper stem diameters especially in volume calculations.
