How long does it take for eagle wood tree to grow before harvesting?

The growth rate of Aquilaria trees, also known as eaglewood trees, can vary depending on the species and environmental conditions. Generally, it takes many years for these trees to reach maturity and produce a significant amount of resinous heartwood, which is the source of the highly prized eaglewood. Depending on the species and growing conditions, it could take anywhere from 20 to over 100 years for the trees to reach a suitable age for harvesting.

Some specific examples of eaglewood tree growth rates include:

- Aquilaria malaccensis: This species is native to Southeast Asia and typically takes around 40 to 50 years to reach maturity, but it can take even longer in some cases.

- Aquilaria crassna: Found in Northeast India and Southeast Asia, this species may reach maturity in around 30 to 40 years, although some trees may take longer to produce substantial heartwood.

- Aquilaria sinensis: Native to China and Vietnam, this species has a relatively faster growth rate compared to others, potentially reaching maturity in 15 to 20 years.

- Aquilaria subintegra: This species is found in Cambodia, Laos, and Vietnam, and it usually takes around 30 to 40 years to mature, though it can vary.

- Aquilaria microcarpa: This species, native to India and Sri Lanka, may reach maturity in around 20 to 30 years.

It's important to note that harvesting of eaglewood trees is tightly regulated and managed due to the limited availability and high demand for eaglewood. Sustainable practices are crucial to ensure the long-term conservation of these valuable tree species.
