Abstract:

Norway spruce is one of two dominating species in Swedish forestry and the most economically important tree species in Sweden. In order to preserve the ability to adapt to a changing environment and to keep populations healthy, genetic diversity has to be preserved. When choosing a small number of individuals from a natural stand to establish a seed orchard the population size decrease. With only a small number of genetically different individuals the risk of inbreeding increase. Furthermore if many clones of the same tree are used in one seed orchard there is also an increased risk selfing. T

Abstract:

The effects of nutrient and biomass distribution on growth and nutrition of an age series of young stands of Sitka spruce (<i>Picea sitchensis</i> (Bong.) Carr) prior to canopy closure have been studied to find out if the concept of steady-state nutrient status, pioneered by T. Ingestad, is valid under field conditions. Three similar experimental sites for this purpose were located at Manor Valley, Glentress and Innerleithen Forestry Commission Plantations, 40 to 50 km south of Edinburgh. Detailed quantitative analysis of the biomass and nutrient dynamics on tree growth have been made in relat

Abstract:

Old-growth stands are important for management, conservation, wildlife, recreation, and maintaining biological diversity in forested landscapes. However, we are lacking the information needed to adequately identify and characterize old-growth stands. This is especially true for high elevation, interior forests. The characterization of stand structure and regeneration pattern will help in the development of site-specific guidelines for identifying old growth stands and restoring some of the old-growth characteristics in managed stands.

Consistent patterns of foliar N concentration and δ<sup>15</sup>N were found in age sequences of foliage. N concentration decreased with age and δ<sup>15</sup>N increased with age. Patterns of δ<sup>15</sup>N may be useful in studying nutrient retranslocation within the canopy because, as far as it is known, they are unaffected by contemporary changes in other leaf components. No evidence for increased efficiency of N recycling in spruce from mixed stands as compared to spruce from pure stands was found. The δ<sup>15</sup>N data appear to confirm that the amount of N retranslocated depends on

Abstract:

On poor peats and heathlands, satisfactory growth of Sitka spruce (<i>Picea sitchensis</i>), planted pure, can only be achieved with repeated applications of nitrogen fertilizer. However, when spruce is planted in mixture with Scots pine (<i>Pinus sylvestris</i>), Lodgepole pine (<i>P.contorta</i>), or Japanese larch (<i>Larix kaempferi</i>) it shows improved nitrogen nutrition and better growth than pure spruce. The mechanism by which the 'extra' nitrogen required to sustain improved spruce growth has not yet been elucidated. A mechanism is proposed in this thesis. The mycorrhizal community i

I used a functional classification scheme to assess the potential wildlife habitat value of snags and logs.

Abstract:

The boreal forest is confined to the Northern Hemisphere and is the most continuous and extensive forest in the world. In North America boreal forest extends from the Pacific to Atlantic coast spanning over 10° latitude. White spruce (Picea glauca (Moench) Voss), black spruce (P. mariana (Mill.) B.S.P.), and trembling aspen (Populus tremuloides Michx.) are among the dominant tree species. Black spruce and trembling aspen may form pure stands and occupy similar sites as their edaphic amplitudes overlap; however, spruce is rare on water-deficient sites and aspen does not tolerate excess water.

Abstract:

Birch is the dominant deciduous tree species in Sweden but only 16 % is found in pure birch stands. The majority of the birch (51 %) is to be found in conifer dominated stands. Swedish forest land comprises approximately of 23 % mixed stands and one problem is that for mixed stands there are few management recommendations. The underlying aim of this thesis was to study the management of mixed forest stands of spruce and birch to achieve good timber quality of birch.

Abstract:

White pine weevil is a pest of interior and Sitka spruce species in British Columbia. It is native to eastern Canada, and migrated to the west. To date, control of the weevil has been ineffective even with the combined use of several control methods. Current research has focused on breeding resistant trees for use in plantations to overcome attack from Pissodes strobi. Knowledge of the weevil genetic structure on a small-scale stand level is extremely important in developing strategies that decrease the possible development of tolerance in P. strobi populations to resistant trees.

Abstract:

A major argument for incorporating deciduous tree species in coniferous forest stands is their role in the amelioration and stabilisation of biogeochemical cycles. Current forest management strategies in central Europe aim to increase the area of mixed stands. In order to formulate statements about the ecological effects of mixtures, studies at the stand level are necessary. In a mixed stand of Norway spruce (Picea abies (L.) Karst.) and silver birch (Betula pendula Roth) in the Ore Mountains (Saxony, Germany), the effects of these two tree species on chemical and microbial parameters in the t
