The trees growing in the open in plains and on ridges in hills have generally shorter and conspicuously tapering stem as a result of wind pressure. On the basis of the depth of the root-system, the trees are classified into shallow-rooted and deep-rooted trees. ∗ Heartwood—inner core of dead wood that supports the tree.
