I'm planning a coppice woodlot using black locust for firewood. Other functions will be fodder for chicks, nectar for bees and useful wood for projects.
There has been much research done at Michigan State since the energy crisis of the 70's on this legume.
A few points I have read about to help fellow b.locust fans.
-they won't tolerate shade.
-they won't tolerate overly damp soils.
-Hungry has one of the largest, non native stands of black locust.
-a part of France has established black locust for the excellent honey production.
-it is one of the fastest growing, hardest woods in the temperate zone.
A permies dream tree.
