Dalbergia oliveri

Dalbergia oliveri, commonly known as Tamalan wood or Burma tulipwood, is a significant timber-producing species belonging to the Fabaceae family. This deciduous tree is globally recognized for its dense, durable, and highly decorative heartwood, which features a distinct reddish-brown color, often marked with dark streaks.

The species is native to the tropical regions of Southeast Asia, primarily thriving in Myanmar, Thailand, Laos, and Vietnam. It is typically found in mixed deciduous forests, where it prefers well-drained slopes and areas with distinct seasonal climates. Its adaptation to these conditions is a major factor in the high quality and hardness of its timber.

Botanically, the tree is characterized by alternate, pinnate leaves and small, fragrant inflorescences. As a legume, it has an efficient root system, often interacting with symbiotic bacteria to fix nitrogen. The mature trees can grow quite tall, developing a cylindrical and straight trunk, which is highly preferred for lumber production in the industry.

Cultivation of Dalbergia oliveri requires specific agrotechnical standards, including full sun exposure and fertile, well-draining sandy or loamy soil. It is intolerant of waterlogged conditions, which can lead to rapid root decay. Silvicultural practices involve careful thinning and pruning to encourage vertical growth and reduce the development of excessive branching, maximizing the commercial value of the wood.

The primary economic use is in the high-end furniture industry, musical instrument manufacturing, and fine woodworking. Given its status as a valuable but slow-growing species, conservation and sustainable plantation management are essential. Common health issues that affect the tree include:

• Root rot caused by pathogenic fungi in poorly drained soils
• Borer insect infestations that weaken the internal structure
• Competition from invasive weeds during the seedling establishment phase
