A force analysis of directional falling

McRae, James Robert (1977-04-08)

Envirorunental concerns have prompted the need for reviving an old art: controlled felling. The methods currently used, jacking and lining, present new and varied problems for the faller in today's environment. One of ...
Hot-yarding as an alternative approach to cable thinning in young forest stands : a comparative study

Lucas, Alan R. (1983-03-01)
An HP-75/HP--86 computer data collection system for recording and displaying logging equipment time studies

Campbell, Thomas M. (2009-04-23)
Mechanical brush control on steep slopes in southwest Oregon

Steffan, Daryl Joseph (1982-06)
Production rates and skidding cost of the FMC model 210 CA high-speed skidder

Ohmstede, Robert H. (1977-06)
Silvicultural mechanical site preparation

Moore, William Wardlaw (1976-05-05)

The preparation of suitable sites for planting and growing of tree seedlings following logging is recognized by British Columbia Forest Service as a major silvicultural problem in the Central and Northern Interior reg ...
A simulation of the operation of a log landing for a heli-stat airship in old-growth timber

Gerstkemper, John C. (2009-04-23)

This paper discusses the development of a computer simulation program for the operation of a log landing for the proposed Heli- stat airship. The first part of the paper describes the time study used to develop produc ...
Skyline thinning production rate equations using the thin simulation model

Starnes, Lawson W. (1984-00)

This paper shows how ten easy-to-use linear skyline thinning production rate equations were obtained by transforming existing but more cumbersome turn time equations using the THIN simulation model [11). The equation ...
A study of soil disturbance and compaction resulting from the use of ground-based logging vehicles in the Sierra Nevada

Lysne, David Holtan (1980-05-28)

Some results of a study conducted in the Sierra Nevada Mountains west of Lake Tahoe are reported. The study measured soil impacts resulting from the use of a Caterpillar Tractor model D6D, a John Deere wheeled skidder ...
