Logging methods- Tree-length logging-Full-tree logging-Cut-to-length logging

The above operations can be carried out by different methods, of which the following three are considered industrial methods:

Tree-length logging

Trees are felled and then delimbed and topped at the stump. The log is then transported to the landing, where it is bucked and loaded on a truck. This leaves the slash (and the nutrients it contains) in the cut area where it must be further treated if wildland fires are of concern.

Full-tree logging

Trees are felled and transported to the roadside with top and limbs intact. The trees are then delimbed, topped, and bucked at the landing. This method requires that slash be treated at the landing. In areas with access to cogeneration facilities, the slash can be chipped and used for the production of clean electricity or heat. Full-tree harvesting also refers to utilization of the entire tree including branches and tops. This technique removes both nutrients and soil cover from the site and so can be harmful to the long term health of the area if no further action is taken, however, depending on the species, many of the limbs are often broken off in handling so the end result may not be as different from tree-length logging as it might seem.

Cut-to-length logging

Big trees are felled, delimbed, bucked, and sorted (pulpwood, sawlog, etc.) at the stump area, leaving limbs and tops in the forest. Harvesters fell the tree, delimb and buck it, and place the resulting logs in bunks to be brought to the landing by the forwarder. This method is usable for smaller timber on ground flat enough that forwarders can operate, but does not work well on steep slopes.

Logging and safety

Logging is a dangerous occupation. In the United States, it has consistently been one of the most hazardous industries, having a fatality rate over 21 times higher than the rate for all workers in the US. Loggers work with heavy, moving weights and the use of tools such as chainsaws and heavy equipment on uneven and sometimes unstable terrain. Loggers also deal with severe environmental conditions such as inclement weather and severe heat or cold. An injured logger is often far from professional emergency treatment.

Traditionally, the cry of "Timber!" developed as a warning alert fellow workers in an area that a tree is being felled, so they should be alert to avoid being struck. The term "widowmaker" for timber that is neither standing nor fallen to the ground demonstrates another emphasis on situational awareness as a safety principle.

The risks experienced in logging operations can be somewhat reduced, where conditions permit, by the use of mechanical tree harvesters and forwarders.
