Alstonia spatulata

Alstonia spatulata is a species of evergreen tree that belongs to the Apocynaceae family. This tree is well-known for its ability to thrive in tropical environments, particularly in waterlogged soils and swampy forest areas where many other timber species struggle to survive.

The tree originates from Southeast Asia, including countries like Thailand, Malaysia, and Indonesia. Its natural habitat is typically found in lowland forests and peat swamps. Because of its native environment, it is highly tolerant of high moisture levels and specific soil conditions characterized by organic matter accumulation.

Botanically, Alstonia spatulata is recognized by its distinct spatulate-shaped leaves arranged in whorls along the branches. The tree can reach significant heights, often growing up to 20 meters. It produces clusters of fragrant, white-to-cream-colored flowers that eventually develop into long, thin follicles containing seeds designed for wind dispersal.

The cultivation of this species requires specific environmental conditions. It demands a warm, tropical climate with consistent humidity and deep, nutrient-rich soils. In an agricultural context, it is often grown as a plantation crop for its light, workable wood and as a source of bioactive compounds used in local traditional medicine practices.

Regarding pests and pathogens, Alstonia spatulata may face challenges from typical tropical wood-boring insects and foliage feeders. Fungal diseases can also occur if the soil aeration is poor or if the plants are subjected to extended periods of stress. Proper spacing and drainage management are essential for maintaining a healthy plantation.

The economic value of this tree is multi-faceted. Beyond its utility in the timber industry, the species plays a vital role in ecological restoration, helping to stabilize soil in swampy regions and providing habitats for various avian and insect species, which enhances the overall biodiversity of the plantation site.
