Planting pine in degraded areas and allowing ecological processes to take over is not just an effective way of restoring native tree species, it can be monetarily beneficial as well. Econo - mically important native species of Sri Lanka ( such as Diospyros quaesita, a type of ebony, and Pericopsis mooniana) can be planted for timber requirements. Caryota urens or the sugar palm, a non- timber forest pro- duce with high economic value can be another option. Vines like pepper and lianas that have medicinal value can also increase economic returns from pine plantations.
Using data on the growth rates of species and market surveys, the authors compared monetary returns offered by pine restoration with that of tea cultivation. Results showed that over a 60 year period, planned cultivation under pine can be 1.5 times more beneficial than tea plantations.
