Abstract:

Several canopy access techniques are reviewed including a preferred method that is presented in detail. Included is a description for devising the necessary equipment and step-by-step instruction for its use. The technique was developed for use with sugar maple with a crown base 12 to 16 m above the ground A combination of mountaineering, hunting, and fishing equipment and techniques is employed to propel an initial line into the canopy and rig the tree so that a rope can be ascended. Based on several years of development and testing, the technique is assessed with regard to possible variations and other techniques. The method should be most useful for practitioners and researchers working in the crowns of mature, stand-grown hardwood tree species like those found in the northeastern and midwestern North America.
