Padauk wood is highly valued in global timber markets due to its distinctive deep reddish-orange color and remarkable stability. This durable hardwood is often used in high-end furniture, musical instruments, and decorative veneers. The term “Padauk” does not refer to a single tree species, but rather a group of closely related species whose native habitats are spread across two different continents.
The Botanical Identity of Padauk
The commercial wood known as Padauk originates from several species within the genus Pterocarpus, which belongs to the larger legume family, Fabaceae. The name Pterocarpus is derived from the Greek words for “wing” and “fruit,” a reference to the unusual, disc-shaped, winged seed pods characteristic of the trees. This genus is pantropical, but the varieties yielding the most commercially significant timber are exclusively found in Africa and Asia. These distinct geographical groups represent different species with unique regional common names.
The Native Range of Asian Padauk Species
The major sources of Asian Padauk are endemic to the seasonal tropical forests of Southeast Asia. One of the most prominent species is Pterocarpus macrocarpus, commonly known as Burmese Padauk, which is native to the Indochinese peninsula. Its natural range extends across Myanmar, Thailand, Laos, Cambodia, and Vietnam. This species is typically found in lowland tropical areas, thriving in mixed deciduous forests that experience a distinct dry season.
Another notable Asian variety is Pterocarpus indicus, often traded as Narra or Amboyna wood. The native distribution for this species is wider, extending from India and Thailand through much of Malesia. Specific countries include the Philippines, where it is considered a national tree, as well as Laos, Cambodia, and Vietnam.
The Native Range of African Padauk Species
The most frequently traded African variety is Pterocarpus soyauxii, which is recognized commercially as African Padauk or African Coralwood. This species is indigenous to the tropical regions of Central and West Africa. Its native habitat forms a belt that runs primarily along the equator and includes several major timber-producing nations. The distribution encompasses countries such as Nigeria, Cameroon, Equatorial Guinea, Gabon, and the Republic of Congo.
The range for P. soyauxii also extends southward into the Democratic Republic of Congo and Angola. This geographical restriction places the species within the dense, humid forest zones of the Congo Basin and adjacent coastal regions.
Defining the Ecosystem: Growth Requirements
Padauk species across both continents share a preference for tropical environments that are subject to seasonal climate patterns. The trees are typically found in lowland to medium elevations, generally not exceeding 750 meters above sea level. They thrive in well-drained soils, often preferring sandy loam or clay loam, and they require full sunlight to establish themselves.
The native habitats of these trees are characterized by substantial seasonal rainfall, which is consistent with tropical monsoon or wet/dry climates. For African Padauk, the ideal environment receives an average annual rainfall between 1,500 and 1,700 millimeters. Asian species like Burmese Padauk are adapted to slightly drier conditions, growing well in regions receiving 1,000 to 2,000 millimeters of rain annually. Ecologically, these Pterocarpus trees function as nitrogen-fixing species, playing a role in maintaining the fertility of the forest soils.
