General Biology

Shorea leprosula is commonly found on well-drained soil in the lowland and hill dipterocarp forests. This is one of the Shorea species whose saplings, unlike many other Dipterocarp saplings, are more tolerant of open areas. As a result, S. leprosula are more successfully used in reforestation than other dipterocarps in Singapore.

Life Cycle

More is known about the life cycle of Shorea leprosula due to the ease and relatively fast rate at which it regenerates. It mass flowers at long intervals of 5–6 years. Strongly scented flowers that bloom in the evening and are pollinated by thrips. Fruit fall about 14 weeks after the start of flowering and can be negatively affected by dry spell. The seeds are attacked by weevils and the fruits can be consumed by pigs and squirrels. 

Human Uses

Its timber is not of commercial value in Malaya.
