Enrichment plantings in the tropical rainforest of Sumatra - a silvicultural challenge.

Abstract

In coastal peat swamp forests of eastern Sumatra, Indonesia, selective logging has removed commercially valuable timber species, and the area is under threat of transformation into non-forest land uses including cultivation. Enrichment planting is seen as one possibility to increase the commercial potential of these forests. Research was conducted in order to demonstrate the need for enrichment planting (a stand structural analysis), and some techniques for line planting were developed, based on measurements of light and growth rates of seedlings of jelutong (Dyera lowii), ramin (Gonystylus bancanus), labu (Endospermum diadenum) and pulai (Alstonia scholaris) over a 10-month period.
