Planted Black Walnut Does Well on Cleared Forest Sites -- if Competition is Controlled

Abstract

After seven growing seasons, survival of black walnut seedlings planted in cleared forest openings did not differ by competition control treatments. The trees grew somewhat larger where all competing vegetation was controlled but almost as large where only herbaceous competition was controlled. Controlling only woody vegetation was no better than no control of any kind.
