Fig. 3. Black locust (Robinia pseudoacacia) has potential as a multi-use, nitrogen-fixing tree for temperate silvopastures. Black locust can increase forage production by improving soil fertility and soil moisture, while reducing microclimate temperatures (31,69). Black locust makes excellent fence posts and firewood and may be suitable for browse, but the species is susceptible to a stem borer (Megacyllene robiniae) (19).
