Equation

As printed (Table 2)

Aleurites moluccana: H = a + b x DBH; a 3.6784, b 0.3101, r2 0.643

In this library's units, ready to compute (m)

Height = 3.6784 + 0.3101 * D

Shade-tree structural study; only height from DBH is a tree-level size equation here (other relationships are crown or trunk height).
