Abstract:

Black walnut offers the highest potential return of any forest tree in the Midwest, but managing walnut in natural stands requires information on the size and value growth of individual trees. We developed an interactive computer program, BLAWAP, that estimates the dbh and height growth of individual, forest grown black walnut trees in Iowa. It uses a taper equation, the estimated dbh and height, and user-supplied information to estimate the value of the tree over the next 20 years. The program and its components are described, and program use is discussed. North. J. Appl. For. 3:135-136, Dec. 1986.
