All this fuss about mulberry ,really in this area you don't see much of it . Black locust is also spotty as is ossage orange .What used to be is catalpa which years ago was grown in groves usually in some area of a field that was hard to farm because of various reasons .Those were used for fence posts ,In my 7.5 acres of woods I have exactly one catalpa which is slowly dying off .Couple more years it will become fodder for the stove
Black locust on the other hand is also invasive .Damned stuff propagates from the roots much like quaking aspen in the mountains of Colorado .In a former life with a former wife I ripped out about 3/4 of an acre taken over by locust .Bought that piece of ground and the courts took it away from me .On that piece of ground I recently bought it's got honey locust down one fence row .That stuff can grow thorns that mimic elk antlers
