A regression analysis that shows the relationship between crown width and tree diameter is presented for jack pine in Quebec. By use of an equation developed by the method of least squares, "Maximum Crown Area" in square feet can be estimated from tree diameter. The relationship between maximum crown area and tree diameter is used as a basis for computing the "Crown Competition Factor" value of a stand. The CCF value on an acreage basis can be determined by accumulating the MCA values of the individual trees comprising the stand.
