Shorea sumatrana

Shorea sumatrana is a prominent tropical tree species belonging to the family Dipterocarpaceae. Widely recognized in the forestry sector for its high-quality timber, this species is a critical component of the rainforests in Southeast Asia. It represents a significant botanical interest due to its structural height and its role in sequestering carbon in tropical regions.

The native range of this species spans Sumatra, Peninsular Malaysia, and Borneo. Shorea sumatrana thrives in hot, humid tropical climates where annual rainfall is high and evenly distributed. It is typically found in lowland dipterocarp forests, preferring deep, fertile, and well-draining soils that support its extensive root system as the tree reaches its maturity.

Botanically, it is a massive tree that can grow up to 50 meters tall. The trunk is generally straight and cylindrical, often free of branches for a significant portion of its height, which is a desirable trait for timber production. The leaves are leathery and persistent, while the winged seeds are adapted for dispersal by wind, facilitating the species' natural regeneration in forest gaps.

Cultivation practices require careful site selection and management. During the nursery phase, seedlings require shade to mimic the forest understory environment. Once established, the trees respond well to controlled thinning, which promotes faster growth rates. Proper spacing is essential to ensure that individual trees receive adequate light for photosynthesis while maintaining forest density to protect the soil.

The wood from Shorea sumatrana is highly valued in the international market as part of the 'meranti' category. It is used in construction, flooring, boat building, and furniture manufacturing. Its durability and workability make it a preferred choice for high-end carpentry.

• Excellent dimensional stability
• High resistance to decay
• Attractive reddish-brown finish
• Versatile manufacturing properties

The species faces threats from various pests, including wood-boring insects and fungal pathogens that attack roots in poorly drained areas. Modern forestry management involves integrated pest control and the monitoring of soil moisture levels to ensure the health of plantations. Maintaining genetic diversity in planting programs is also crucial for long-term sustainability.
