I am in the process of planning a pond. On one side I'm planning on having a thirty foot wide peninsula with a 3' diameter native pecan located in the center of the point. The land already has this general shape.
My question is: how much undisturbed land would be required if I decided to make this raised point into an island instead of a point? I realize the feeder roots extend beyond the drip line of the tree, but we've all seen pecans growing right on the edge of river banks. Is there a general rule of thumb for how much of the root system can be lost and still expect the tree to live?
Any thoughts or experience in this area appreciated.
