Aerial cone collection techniques in British Columbia

Technical Note, Forest Engineering Research Institute of Canada (TN-69): 55
Aerial cone collection techniques in British Columbia
Two aerial methods were used: (a) the top clipping method in which tops of trees are pulled into a hovering helicopter and then cut off; and (b) the use of aerial cone rakes, suspended below the helicopter - a basket around the outside of the cone collects the material. Data are presented on 12 aerial collections from various species in British Columbia.
