Control of black locust trees is an ongoing process on the refuge. Pictured here is a large patch of black locusts undergoing basal bark applications for trees less than four-inch DBH and girdling with herbicide application on trees greater than four-inch DBH.

Treatments include mowing, burning, cutting with herbicide stump treatment, basal bark chemical applications, girdling and chemically treated girdles. Several formulations of triclopyr and methylated seed oil have been tried to arrest the spread. Most black locust reproduction is vegetative by means of root suckering and stump sprouting. Copious root suckers arise spontaneously from the extensive root system of trees. Richard Hager is seen here, surveying the work that he and several volunteer interns have completed.
