Wood warping costs the wood industry in the U.S. millions of dollars per year. [citation needed] Straight wood boards that leave a cutting facility sometimes arrive at the store yard warped. Although wood warping has been studied for years, the warping control model for manufacturing composite wood hasn't been updated for about 40 years.

Slash generated during logging operations may increase fire hazard, and some North American states have passed laws requiring the treatment of logging slash. [2] Logging slash can be chipped and used (for example) in the production of electricity or heat in cogeneration power-plants, [ 3 ] or simply burned onsite.
A gyppo or gypo logger is a logger who runs or works for a small-scale logging operation that is independent from an established sawmill or lumber company. The gyppo system is one of two main patterns of historical organization of logging labor in the Pacific Northwest United States, the other being the "company logger".
The men working at the end of the boom would sort the logs according to their corresponding brand and float them into the correct holding pond along the bank of the river. During the height of the lumber industry in Lycoming County, 1861–91, the various mills produced 5.5 billion board feet (13 million m³) of lumber.
Arising in cut timber they generally cause a reduction in strength. When found in a log they can result in a significant amount of waste, when a log is converted to lumber. Apart from heart shakes, often found in trees felled past their best, shakes in a log have no effect on the strength of shake free lumber obtained therefrom. [1]
The log drive was one step in a larger process of lumber-making in remote places. In a location with snowy winters, the yearly process typically began in autumn when a small team of men hauled tools upstream into the timbered area, chopped out a clearing, and constructed crude buildings for a logging camp .

The 1935 Pacific Northwest lumber strike was an industry-wide labor strike organized by the Northwest Council of Sawmill and Timber Workers Union (STWU). The strike lasted for more than three and a half months and paralyzed much of the lumber industry in Northern California, Oregon and Washington state. Although the striking workers only ...
