    Plantation Silviculture in Europe provides an up-to-date, succinct, and comprehensive overview of current European plantation forestry practices. Recognising that plantation silviculture today is no longer largely a question of how to grow large-scale industrial plantations, the authors have included chapters describing other, more diverse reasons for establishing trees. The Spruce and Peatland Responses Under Changing Environments (SPRUCE) experiment is the primary component of the Terrestrial Ecosystem Science Scientific Focus Area of ORNL's Climate Change Program, focused on terrestrial ecosystems and the mechanisms that underlie their responses to climatic change. The experimental work is to be conducted in a Picea mariana [black spruce] – .

    Introduction. Mixed second growth stands of western hemlock (Hw) and Sitka spruce (Ss) make up nearly half of the timber harvesting land base on Haida Gwaii, and are representative of other second-growth mesic sites found within the Coastal Western Hemlock biogeoclimatic zone (CWH) in B.C. Intensive silviculture was strongly supported with government sponsored forestry programs in the . Black spruce Picea mariana survival was 65–94% over 1–13 years. Red maple Acer rubrum survival was 72% after three years. Poplar Populus spp. survival was 9% after three years. Between and , tree saplings were planted into bare peat, in single species blocks (1,–2, stems/ha), in up to four separate bogs.

    Prior research has demonstrated the importance of water limitations and increasing temperatures on upland black spruce (Picea mariana [Mill.] B.S.P.) tree growth, which is a dominant component of the North American boreal forest. However, little work has been done to investigate the connectivity between growth and hydro‐climate in peatland black spruce systems. However, little work has been done to investigate the connectivity between growth and hydro‐climate in peatland black spruce systems. The boreal forest is the largest global terrestrial biome and is highly threatened due to current and projected increases in temperatures for the northern latitudes. Here we explore the dynamics among annual.

Uneven-aged silviculture for peatland second-growth black spruce by Marc R. MacDonell Download PDF EPUB FB2

Uneven-aged silviculture has previously not been at tempted in northeastern Ontario, and forest industries and natural resource managers have no information on effec tiveness or cost.

A project was initiated in to provide information on uneven-aged silviculture in second-growth peatland black spruce. The project investigated the use of.

An uneven-aged silviculture experiment was established in second-growth peatland black spruce (Picea mariana [Mill.] B.S.P.) stands in the boreal forest of northeastern Ontario, Canada in A basal area growth model was developed to predict the growth of individual trees in second-growth black spruce (Picea mariana (Mill.) BSP) stands on northeastern Ontario peatlands.

The data were derived from stem analysis trees collected in and from stands harvested years earlier. Stand growth forecasts are being developed for second-growth peatland black spruce for new partial cutting techniques.

It is hypothesized that these harvesting techniques will yield an increase in merchantable volume over time, from m3 ha-' year-' to m3 ha-1 year-1 by increasing the growing space for the remaining stand. SILVICS OF BLACK SPRUCE (Picea mariana (Mill.) B.S.P.) Common names: bog spruce, swamp spruce, red spruce.

Field identification aids: usually the only spruce growing in bogs or swamps - grey-green to blue-green, blunt-pointed, four-cornered needles that can roll between your fingers - usually the only spruce growing in bogs or swamps. Practices for eastern boreal black spruce forests. In the eastern Canadian boreal forest, older natural stands of black spruce (Picea mariana) frequently contain abundant advance regeneration of that species.

Such two-storied stands are common on a range of sites in Québec, but further west are increasingly restricted to peatland sites. Published on the web 11 October Received Novem Accepted August 1, This article is one of a selection of papers published in the Special Forum IUFRO Uneven-Aged Silvicultural Research Group Conference on Natural Disturbance-Based Silviculture.

Silviculture is the practice of controlling the growth, Uneven-aged forestry The Femel selection cutting (group selection cutting) (Femelschlag) Black spruce open plantation had significantly smaller volume (97 cm³) compared with black spruce sheltered ( cm³), as well as white spruce open ( cm³) and sheltered ( cm³.

In response to silvicultural systems, Groot and Hokka [ 10 ] demonstrated that in uneven-aged black spruce stands, the average diameter growth of advance regeneration responds positively over a year period following a regeneration harvest, peaking at 10 years and.

Dynamics of tree growth in even- and uneven-aged stands at the limit of the closed black spruce (Picea mariana) forest in Quebec (Canada) were assessed on 18 plots with ages ranging from 77 to years.

Height, diameter and age of all trees were measured. Uneven-aged silvicultural systems in black spruce have been recommended under certain conditions. In Minnesota, uneven-aged methods were explored in the mid- to lateth century.

Group or individual tree-selection methods have been suggested in stands on poor sites where layering is common (HeinselmanJohnston and Smith ). Uneven-aged or all-aged management is best applied on poor sites where stands are windfirm and have abundant layering. Eastern dwarf-mistletoe causes serious problems for black spruce in the Lake States and eastern Canada.

A selection criteria for advanced regeneration and a tree classification method for crop trees were developed. In addition, the study includes a review of literature relevant to developing and executing a selection silviculture system for a mixed species stand.

Black spruce is a desirable component in pure or mixed-species stands, either with other conifers, such as lodgepole pine or white spruce, or hardwoods, such as trembling aspen, in northern, montane boreal forests.

Black spruce regenerates naturally following fire disturbance or can be planted if it was a minor component in the original stand. Inan uneven‐aged silviculture experiment was established in second‐growth peatland black spruce stands in the boreal forest of northeastern Ontario. Three levels of harvesting intensity were tested.

Fifteen‐year results indicate that light‐ and medium‐intensity harvest treatments (35‐50% basal.
