Abstract:Measured distributions of leaf inclination angles and leaf azimuth angles from one stand of red maple (Acer rubrum L.) are used to modify hemispherical photograph determinations of leaf area index in two other plots of red maple as well as in the stand where structure measurements were made. LAI determinations by this technique were within 3.5% of leaf weighting measurements and 5.8% of LAI measurements by a point drop technique. This is approximately twice the accuracy of the photograph technique without calibration. For. Sci. 33(1):210-216.
