Variable Plot Cruising: A Short-Cut Slope Correction Method
Abstract:In variable plot cruising it has been the practice, when prisms or angle gauges are being used, either to make multiple corrections taking account of the slope to each tree, or to use a secant multiplier for enlarging uncorrected slope circles. Error is encountered when the secant of the average slope at each point is used, and loss of control of the sampling intensity occurs even when mathematical error is overcome by use of the secant of the maximum slope at each point. With the described method only one slope correction need be made at each point. Methods of field implementation are suggested, and a table of instrument settings is provided.

More about this publication?
- The Journal of Forestry is the most widely circulated scholarly forestry journal in the world. In print since 1902, the Journal has received several national awards for excellence. The mission of the Journal of Forestry is to advance the profession of forestry by keeping forest management professionals informed about significant developments and ideas in the many facets of forestry: economics, education and communication, entomology and pathology, fire, forest ecology, geospatial technologies, history, international forestry, measurements, policy, recreation, silviculture, social sciences, soils and hydrology, urban and community forestry, utilization and engineering, and wildlife management. The Journal is published bimonthly: January, March, May, July, September, and November.
