The greatest problem facing lumbering in Tropical Africa is that the trees do not grow in pure stands. Unlike in some other parts of the world where trees are grown in neat plantations, in tropical Africa, trees tend to grow in mixed and uneven stands, making it difficult and costly to extract and process them for lumbering. Additionally, tropical African trees are often buttressed at the base, which can make it challenging to fell them and extract the valuable timber. These factors make it difficult for lumbering operations to be profitable and sustainable in the region. While further expansion of sawmills may not be viable in some areas due to market conditions, the main challenge facing lumbering in Tropical Africa is the lack of easily accessible and extractable trees due to their mixed and uneven stands.
