Lannea welwitschii

Lannea welwitschii is a large tree belonging to the Anacardiaceae family. In its natural environment, it can reach heights of up to 30–35 meters, characterized by a straight, cylindrical trunk with distinctive buttresses at the base.

This species is native to tropical Africa, widely distributed across West and Central African countries, including Nigeria, Cameroon, and Gabon. The species thrives in humid tropical forests, often found in alluvial soils near river systems and in foothill regions.

The plant has high requirements for heat and humidity and cannot tolerate prolonged drought periods during its juvenile stage. Optimal growth conditions include well-drained fertile soils, rich in organic matter, with an acidic to neutral pH level.

Botanically, the species is distinguished by its compound alternate leaves and small flowers arranged in raceme inflorescences. The fruits are small drupes, serving as an important food source for wildlife, which facilitates seed dispersal in natural ecosystems.

The commercial use of Lannea welwitschii is primarily focused on the production of high-quality timber. It is extensively utilized in the furniture industry, veneer production, plywood, and carpentry due to its moderate density and excellent workability.

Major threats to this species are linked to intensive deforestation in its native range. Populations are declining due to land-use changes and the conversion of forest areas for agricultural purposes to cultivate other commercial crops.

In the wild, the tree can be susceptible to various wood-boring insects and fungal trunk diseases, particularly in waterlogged conditions or following mechanical damage to the bark. The resilience of mature specimens against pests is generally considered moderate.
