A technique is described for estimating a foilage profile in a forest by a combination of measurements over random lines of points: (1) counts of leaf contacts on a plumb line below a tripod, (2) sightings on the heights of lowest leaves over grids of points, and (3) the proportions of sky unobscured by leaves.
