Abstract:

This report summarizes and evaluates results of visibility studies conducted in a tropical deciduous forest, Mediterranean-type forests, mid- latitude mixed forests, and a high-latitude coniferous forest, together with an evaluation of the measurement techniques employed in these studies. Based on this evaluation, it is recommended that a Secchi disk a flat, dull-white surface, mounted on a tripod of local materials, be used as a standard visibility measuring method for forested areas. By using this standard system, comparable visibility data will be obtained from representative stands of vegetation under various environmental conditions.
