    This study was designed to test the hypothesis that large-scale pre-commercial thinning (PCT) and repeated fertilization 15–20 years after the onset of treatments in young lodgepole pine (Pinus contorta var. latifolia Engelm. ex S. Wats.) stands would enhance relative habitat use by hares, deer, and moose compared with unmanaged stands. Study Cited by: Pre-commercial Thinning Operational Guidelines: for lodgepole pine and dry belt Douglas-fir; Pre-commercial thinning of free growing stands conducted on behalf of the Small Business Forest Enterprise Program should be reported following ministry procedures.

    Photographs (summer ) of lodgepole pine stands at Summerland (a) thinned to stems/ha in , (b) thinned to stems/ha in , and fertilized five times from to , (c) an unthinned lodgepole pine stand, and (d) an old-growth lodgepole pine stand, with some Douglas-fir, interior spruce, and subalpine fir trees. During the years first commercial thinning of lodgepole pine at SCA took place. The goal of the hereby presented study was to investigate the growth and stability in those firstly-thinned lodgepole pine stands a few years after : Merle Hämäläinen.

    Clearcutting is uncommon in central and eastern Oregon, with the exception of its use in lodgepole pine forests infested with mountain pine beetles. The reason thinning is much more common is because of the drier climate east of the Cascade Crest. In commercial thinnings, the immediate value of the removed trees pays the thinning costs. If the value of the trees does not return enough to pay thinning costs, the practice is a precommercial Size: 1MB.

Precommercial Thinning of Lodgepole Pine: Long-term Effects on Growth & Yield, Product Value and Wood Properties Jim Stewart and Jared Salvail Canadian Wood Fibre Centre INGY Winter Technical meeting 16 April Inthe Canadian Forestry Service (CFS) established a commercial thinning trial in a year-old lodgepole pine-dominated stand near Kananaskis, Alberta.

Seventy percent of the total volume was removed, and density was reduced from 7 to 1 trees per hectare. Sample plots established in. Summary: A Forest Engineering Research Institute of Canada study on the effect of commercial thinning and fertilizing of lodgepole pine on attack by mountain pine beetle compared the productivity and costs of thinning to those of clearcut harvesting.

The thinning operations were less productive than the clearcuts on both sites. precommercial thinning of lodgepole pine could improve merchantable volume and quality at a young age, and in turn shorten rotation and increase annual allowable Commercial thinning of lodgepole pine book.

Beaver Lodge Forest Lands. Commercial Thinning Research. Commercial thinning is an intermediate harvest in immature stands, where trees have reached merchantable size, and all or part of the felled trees are extracted for useful products.

As practiced in British Columbia, commercial thinning is generally part of a clearcut silvicultural system.

Thinning Lodgepole Pine Increases Tree Vigor and Resistance to Mountain Pine Beetle R. MITCHELL R. WARING G. PITMAN ABSTRACT. Thinned and unthinned stands of lodgepole pine in eastern Oregon were evaluated in to determine their vigor and susceptibility to attack by outbreak populations of the mountain pine beetle.

Woi\booK Woodland Stand Management 63 Thinning to Prevent Mountain Pine Beetles in Lodgepole and Ponderoso Pine Devastating outbreaks of moun- tain pine beetle occur periodically throughout thelodgepole and ponderosa pine forests of western North America.

Individual outbreaks last up to two decades, killing as much as 60 percent of the trees and. The MacKay installation was established in with the objective of determining whether precommercial thinning of lodgepole pine could improve merchantable volume and quality at a young age, and in turn shorten rotation and increase annual allowable cuts.

Guidelines for Spacing of Lodgepole Pine Background: The current large outbreak of mountain pine beetle is unprecedented in the history of the province.

This widescale infestation is killing vast areas of mature There is some risk that thinning in suppression areas may predispose treated stands when outbreaks in the area intensify. We sampled the abundance and diversity of secondary bark beetles in mature thinned and unthinned lodgepole pine, Pinus contorta Dougl.

ex Loud., stands (ca. and trees/ha, respectively) near Whitecourt, Alberta. We examined the factors that might influence any differences in abundance and diversity between thinned and unthinned stands.

Ogden, Utah: U.S. Dept. of Agriculture, Forest Service, Intermountain Forest and Range Experiment Station, (OCoLC) Lodgepole pine is the most common-ly used name for the inland varieties of the species, but it is also called black pine and tamarack pine.

areas of the West, ponderosa pine primarily occupies the dominant canopy layers, whereas shade-tolerant grand fir, white fir, or Douglas-fir occupy the intermediate and suppressed layers.

A low thinning in these stands therefore favors the development of the dominant and codominant ponderosa pine (fig.

1).Cited by: Silvicultural practices such as pre-commercial thinning (PCT) and repeated fertilization have been used successfully around the world to increase forest biomass for conventional wood products, biofuels, and carbon sequestration.

Two complementary studies were designed to test the hypotheses (H) that large-scale PCT and PCT with repeated fertilization of young (13–17 years old) lodgepole pine (Pinus Author: Thomas P. Sullivan, Druscilla S. Sullivan, Pontus M.F. Lindgren, Douglas B. Ransome, Lisa Zabek. Each of the six treatments is replicated twice, for a total of 12 treatment plots.

Treatment plots vary in size depending on thinning level, and range from ha to ha. The study was established in in a year-old lodgepole pine stand northeast of Canal Flats within the dry cool subzone of the Montane Spruce biogeoclimatic zone.
