Another tree threatened by movement of firewood - black walnut!
Another tree threatened by movement of firewood - black walnut! An insect and fungus combination is killing walnuts planted in towns across the West. The beetle is often found in larger branches and trunks – just the kind of wood used for firewood. At a minimum, any walnut wood should be debarked before being moved. Even this measure might not be sufficient, since both the beetle and the fungus have been found in the sapwood.
Black walnut grows wild in the eastern forest, ranging from Iowa, Illinois, and southern Michigan across to the Mid-Atlantic, and into the South – except along the Atlantic and Gulf coastal plains and the Mississippi delta. Black walnuts have been planted as street or park trees in many Rocky Mountain states.
