Suppose that you are choosing a rotation length to maximize the timber and non-timber benefits of your forest stand for infinitely many forest rotations. Suppose that the non-timber benefits in any time period are greater than zero. Which of the following statement is true?

a. You will choose a rotation length that is shorter than if you were only maximizing timber benefits.

b. You will choose a rotation length that is longer than if you were only maximizing timber benefits.

c. You will never harvest the trees--non-timber values are just too important.

d. The rotation length you choose could be longer or shorter than if you were only maximizing timber benefits, depending on the type of non-timber values.
