Hairy-leaved Dipterocarpus
Dipterocarpus crinitus
Description
The Hairy-leaved Dipterocarpus (Dipterocarpus crinitus) is a significant tropical tree species belonging to the Dipterocarpaceae family. Known for its massive size and ecological importance, it stands as a key canopy-forming species within the lush rainforests of Southeast Asia, contributing to the structural complexity of these biodiverse environments.
Geographically, this species is native to the Malay Peninsula, Sumatra, and Borneo. Its natural habitat is characterized by lowland dipterocarp forests where rainfall is abundant and evenly distributed throughout the year. The tree thrives in warm, humid climates, typical of equatorial zones, and is rarely found outside these specific environmental conditions.
Botanically, Dipterocarpus crinitus is distinguished by its leathery, hairy leaves—a key diagnostic feature that helps differentiate it from other related species. The tree can grow to heights exceeding 45 meters, possessing a straight, cylindrical trunk and a wide, spreading crown. Its fruit is winged, facilitating dispersal via wind over short distances within the forest floor.
From a silvicultural perspective, the cultivation of this species is complex. It requires deep, fertile, and well-drained soils to support its rapid vertical growth. Seedlings are notably shade-tolerant in their youth, a trait common to many forest-giants, requiring careful forest management to ensure successful regeneration in replanted areas or managed forestry plots.
Commercially, the timber harvested from this species is highly valued and often marketed as a type of keruing. It is prized for its structural strength and durability, making it suitable for heavy construction, flooring, and plywood manufacturing. Beyond timber, the species is essential for local hydrological regulation and remains a focus for conservation efforts due to the impact of deforestation.
- High-density timber production;
- Ecological importance as a keystone species;
- Sensitivity to forest fragmentation;
- High biomass production potential in managed forests.
