S. rautanenii fruit are comparatively bulky, and have in the past been distributed by Kudu and elephant (Bainbridge 1965). However, the presence of both species has declined significantly in the communal areas of Namibia, and will therefore not be able to contribute much in the future. Some seedlings can be seen next to tracks that lead to the individual stands. These seedlings can probably be attributed to nut collectors who have lost some of the fruit.
The fruit of B. plurijuga is a dehscent pod that opens explosively in low atmospheric humidity (Childes 1989).
The list below provides an indication of the dispersal mechanizms of some species.
