Results of this study suggest that managed plantations of western hemlock-Sitka spruce can receive sufficient density control from precommercial thinning to maintain adequate stand development to a rotation age harvest without commercial thinning : L.

Kellogg. The purpose of this study was to provide appropriate harvesting, silviculture and economic data in a comprehensive evaluation of four alternative stand management treatments (three different thinning prescriptions with a basal area per acre removal ranging from 49 percent to 67 percent and a no-thin, control prescription) conducted on a 32 year old managed western hemlock-Sitka spruce plantation.

Title: A Stand Management Strategy for Young Western Hemlock-Sitka Spruce Forests Abstract approved: AN ABSTRACT OF THE THESIS OF presented on Ap C-ex2LvJ Eldon D.

Olsen Western hemlock-Sitka spruce forests, where prior precommercial thinning has occurred, constitute one of the most productive young-growth management types along the Pacific Coast from Oregon to.

Abstract. There is increasing interest worldwide in managing forests to maintain or improve biodiversity, enhance ecosystem services and assure long-term sustainability of forest resources. An important goal of forest management is to increase stand diversity, provide wildlife habitat and improve forest species diversity.

Researchers examined 18 unthinned western hemlock–Sitka spruce stands that regenerated following clearcutting, with stand ages of 15–46 years.

Suitable older stands were not found, and the stands studied had not yet reached the culmination of MAI, so it was necessary to estimate their future wood production with a growth model.

Fertilization research has confirmed that nitrogen (N) deficiencies are widespread in B.C. forests, and that N additions often have a substantial positive effect on tree and stand growth.

Other nutrient deficiencies, either induced or aggravated by N fertilization, have also been implicated as growth-limiting factors, especially in interior.

Strategies for dealing with bark beetle populations should be addressed in the forest five-year development plan, at the silviculture prescription (pre- and post-harvest), and followed throughout the life of the.

Data Augsburg Western Forests. The Augsburg Western Forests (AWF) case study region is located in the federal state of Bavaria, in Southern Germany, to the west of the city of Augsburg (Fig. 1).The case study region is a so called “Nature Park” (German: “Naturpark”), which is a legally defined region, where a permanent environmentally friendly land use is strived for and where.

The FOREST STAND DENSITY GUIDE, Table 1, gives the optimum stand densities by stage of development for 15 commercial tree species common to the State of Washington. Densities for minimum reforestation (naturally established and planted), young stands (sapling and small poles) and older stands (small and large sawtimber) are based on.

Limited information exists on the growth and yield of young mixed western hemlock (Tsuga heterophylla) and Sitka spruce (Picea sitchensis) stands on the Queen Charlotte Islands following pre-commercial thinning and fertilization.

As a result, research into thinning and fertilization was initiated by the South Moresby Forest Replacement Account. Accounting for carbon gains and losses in young-growth forests is a key part of carbon assessments. A common silvicultural practice in young forests is thinning to increase the growth rate of residual trees.

However, the effect of thinning on total stand carbon stock in these stands is uncertain. In this study we used data from long-term growth and yield plots to quantify the carbon stock.Managing young upland forests in southeast Alaska for wood products, wildlife, aquatic resources, and fishes: problem analysis and study plan.
