Helicopter Logging by Boeing CH 234 Chinook
Heli-Logging, or Helicopter Logging, is a method of logging that uses helicopters to remove cut trees from forests by lifting them on cables attached to a helicopter. Helicopter logging is often used in inaccessible areas of forests. Because the use of helicopters reduces the level of infrastructure required to log in a specific location, the method also helps to reduce the environmental impact of logging. It also can increase the productivity in these remote areas.
Heli-Logging is based on individual tree selection. The selection process is done by engineers and surveyors. The selected trees are then marked and their diameters are recorded. Once the trees are selected they are climbed, the limbs are removed and the trees are topped. The selected trees are then partially cut at the stem and supported by wooden wedges. The stem is then grappled by the helicopter and pulled until the wood breaks at the partial cut. The logged trees are then brought by helicopter to a predetermined roadside location or dropped into open water where they are collected.
Heli-loggers rank among the highest-paid workers in the logging industry, earning double and sometimes almost triple the amount of industry averages.
