“As increasing human population and fires from the savannah are continuously eating into the forest belt, it seems likely that the distribution of the forest members of the fusca group will continue to retract. In 1912 Simpson described how G. Fusca was found in Sierra Leone along a certain 37-mile stretch of road which ran through thickly wooded country skirting mountains densely clothed in thick forest; in 1946 I visited the area to find no fusca, but bare mountains, grassland, and only a few patches of low secondary thicket.”
