As normal, all this is discover, and trying to know the difference between what we read, and what is real. This is what I love about Africa, or World Travel.
This site talks about the history of Teak in Togo. http://www.itto.int/sfm_detail/id=12360000
"The most important commercial tree species is Tectona grandis (teak). Teak plantations were introduced
in 1910 from Burma by the Germans and have become well adapted to the country. The species regenerates naturally and is widely used in agroforestry plantations, as street trees and in commercial planted forests. A silvicultural system to induce natural regeneration has been developed by ODEF and is practised in some of the older teak stands."
