Juglans Nigra is known by the common names Black Walnut or American Walnut. This is one of the later trees to leaf out in the spring. There are several trees along the trails in Fort Yargo State Park, notably along segments 4 and 6. You can tell them by the telltale piles of nut husks that accumulate under the trees.
