Horizontal Line Sampling in Upland Hardwoods
Abstract:Continuous horizontal line sampling combines the advantages of PPS sampling and of strip cruising. Field work is concentrated on measuring trees. The method offers a choice of ways to control sample intensity. The direct estimate of a horizontal line sample is the sum of diameters per unit area of land. Tallying by diameter class permits calculation of tree frequency and number of trees per unit area of land. The average diameter calculated is the "average" assumed by nonforesters. Tally sheets may be formatted to show stocking percent, diameter growth required for full stocking, or volume.
