From the results of this study, crop-tree thinnings by the D+4 or Crown Rules are not recommended for overstocked year-old western larch stands, unless other resources benefit enough to offset the disappointing crop-tree growth response of the thinned stand.
Instead, low thinning is recommended, preferably when the stand is younger. Get this from a library. Crop-tree thinning a year-old western larch stand: year results. [Dennis M Cole; Intermountain Forest and Range Experiment Station (Ogden, Utah)]. Western larch grows best in the cool climates of mountain slopes and valleys on deep porous soils that may be grav-elly, sandy, or loamy in texture.
The largest trees grow in western Montana and northern Idaho. Western larch characteristically occu-pies northerly exposures, valley bot-toms, benches, and rolling topography. Cubic volume growth and tree vigor of year-old western larch (Larix occidentalis) with and without dwarf mistletoe (Arceuthobium laricis) were measured 15 years after thinning.

Wood heavy, hard, strong, close grained, red, durable. Buds small, globose, brown, hoary. Western Larch needles are 3-sided, while Alpine Larch needles have 4 sides. Also, Western Larch cones connect to the branch on short stalks, while Alpine Larch cones are nearly stalkless.
Uses: Western Larch is made into lumber used for framing and finishing. It's also used for pulp and firewood. Names: Occidentalis means "western," and Larix. 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. Crop-Tree Thinning a Year-Old Western Larch Stand: Year Res u Its. CO~1PLETED /.6i. Dennis M. Cole. OR\GINAl. BEST COPY AVAILABLE.

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 Author: Thomas P.

Its seeds are prized as food by many birds, including pine siskins, redpolls, and crossbills. The western larch was one ofFile Size: KB. It is a large deciduous coniferous tree reaching 30 to 60 metres (98 to ft) tall, with a trunk up to metres ( ft) diameter. The largest known western larch is feet (47 m) tall and 22 feet ( m) in circumference with a 34 feet (10 m) crown, located at Seeley Lake, Montana.
 The crown is narrow conic; the main branches are level to upswept, with the Family: Pinaceae. Our study is superimposed on the Western Larch Density Management Study (WLDMS), a western larch precommercial thinning study located in northwestern Montana, USA and established in by the USDA Forest Service (Schmidt, ).The WLDMS is replicated at four sites (i.e., blocks), which were chosen for their uniform stocking and to capture the productivity gradient of western larch Cited by: Thinning is a term used in agricultural sciences to mean the removal of some plants, or parts of plants, to make room for the growth of others but does not involve the cutting of the whole ive removal of parts of a plant such as branches, buds, or roots is typically known as pruning.
In forestry, thinning is the selective removal of trees, primarily undertaken to. It was a lack of measurement that cost the old champion Western larch its title, according to Sheri Shannon, the national Big Tree Program coordinator in Washington, D.C.

Western Larch. Larix occidentalis. By Lori Micken. Larch, also known as tamaracks*, are one of the most remarkable trees of the pine family.
After the leaves of aspen and other deciduous species fade and die in autumn, the larch turn gold—one of the few conifers to do so. North American larches are typically observed as either tamarack or western larch and can be found in many parts of North America's lush deciduous forests.
Other conifers include bald cypress, cedar, Douglas-fir, hemlock, pine, redwood, and spruce. How to Identify Larches. Western larch grows in valleys and on the lower slopes of mountains in the southern Interior of British Columbia.
As it is intolerant to shade it does well in open stands. This large tree can grow to 80 metres tall and metres in diameter.
Western larch usually grows in mixed stands with Douglas-fir, western hemlock and lodgepole pine. IMMEDIATE FIRE EFFECT ON PLANT: Mature western larch are able to withstand most fires; poles may survive low to moderate fires [30,].Although young trees may survive high temperatures for a short time, thin-barked seedlings and saplings are readily killed by fire [19,33,].Bark thickness, crown function, and tree vigor, as well as the.
Larch has a characteristic where is splits vertically easily. Made great fence rails and shakes for roofing. Interestingly, it is a preferred tree to leave in thinning stands throughout the Western US because the trees needles do not want to burn as readily as most of the other species around it.

The red crossbill eats some western larch seed. Last week, whilst walking my dog, I noticed lots of larch cones on the forest floor, some still attached to small twigs and branches.
I picked a few up with the intention of learning more about larch seeds and of seeing whether I could grow a larch tree from seed. References for species: Larix occidentalis 1. Fire regimes of western larch - lodgepole pine forests in Glacier National Park, Montana.

However, in all cases, crop trees must possess a crown structure and can-opy position that allows them to respond to release and remain competitive as the stand matures.
Table 1 provides examples of crop tree criteria by com-mon management objectives. Tamarack is a common name for larch.

Including trees of the new regenerated layer, the mean tree heights in the thinning treatments (– m) were lower than that in the control ( m) 11 years post thinning.
This significant disparity may also result from thinning preference against western larch, which had the greatest pretreatment density in the > m : Chenchen Shen, Andrew S Nelson, Terrie B Jain, Meghan B Foard, Russell T Graham.
Larch stands were treated with50 and 25 per cent thinning intensities to evaluate the effects of thinning on the persistence of seeds in two burial positions (under litter and in soil) and at two burial times (6 and 12 months), and on the seed germination at five burial positions (on top of litter, on top of soil, between litter and soil Cited by: 9.Presents detailed age structure for two western larch stands that historically experienced frequent fires.
