      1. Introduction. After disturbance by fire or clear-cutting in the western boreal forests, white spruce (Picea glauca (Moench) Voss) seedlings are often mixed with abundant trembling aspen (Populus Tremuloides Michx.) regeneration (Peterson and Peterson, ).For the first six decades aspen tends to dominate the stands while the more shade-tolerant spruce . In Europe, numerous Norway spruce (Picea abies L. Karst.) provenance trials have been established and evaluated at a juvenile age. Still, information about the adaptation potential and long-term fitness of transferred seedlots in the Baltic Sea region is lacking. The aim of the study was to evaluate the adaptation capacity of provenances and assess the patterns of their long .

      This review will use existing data from established provenance trials to examine the evidence for local adaptation and its scale in a number of native tree species in different parts of the world (e.g. tropical, Mediterranean, temperate, boreal). These trials have been measured and in some cases results published in a range of formats.

Here, we screen a range-wide year old white spruce provenance trial for frost rings, light rings, double-rings and blue rings as indicator of maladaptation. Provenances originating near the test site showed the least amount of xylem anomalies, indicating that they are correctly adapted to the environment in which they occur.

Results from provenance trials of tree species have suggested that: (1) at least for quantitative traits such as growth rate, local climatic conditions are becoming suboptimal for some forest populations; and (2) the potential for enhanced land productivity resulting from a warmer climate in boreal forest regions will not be fully realized by Cited by: BSP) provenance trials established from to Population response functions based on February minimum temperatures were developed for 23 Ontario and Great Lakes states provenances to predict climate values maximizing height growth for individual seed by: Boreal forest provenance tests used to predict optimal growth and response to climate change.

Parker a. a Faculty of Forestry and the Forest Environment, Lakehead University, Oliver Road, Thunder Bay, ON P7B 5E1, by:   The CFS established the Maritimes red spruce provenance trial in and This trial consisted of 30 provenances, most of which were from Canada’s Maritimes region, specifically the provinces of New Brunswick and Nova Scotia, two provenances from Maine, and two provenances from West Virginia (Fig.

Black spruce provenance data was obtained from remeasurements on a portion of the Canadian Forest Service’s (CFS) long-term black spruce provenance trial, which originally incorporated seed Cited by: In this study, a meta-modelling approach was used as a mechanism for providing yield forecasts by combining meta-data from white and hybrid spruce provenance trials across the wide expanse of the Canadian boreal forest.

Height trajectories were modelled using the widely-used Chapman–Richards model (e.g., [7,68,69]) as the base model. Height, diameter, and survival data were obtained from 16 rangewide jack pine provenance trials in eastern Canada and the United States.

Climate data for each seed source and test location were used to relate height growth to 72 climate variables. Species native to this region but found primarily in boreal forests, deserts, grasslands or Mediterranean climates were excluded.

We initially searched using Web of Science (Thompson Reuters, New York, NY) for articles on provenance trials and common gardens individually for each tree species native to British Columbia (Klinka et al. Local and regional timber shortages may be ameliorated via planting improved stocks with higher yields.

In this dissertation, I addressed an important knowledge gap on the impacts of tree improvement programs on yields of white spruce (Picea glauca (Moench) Voss) and hybrid spruce (Picea engelmannii Parry ex Engelmann x Picea glauca (Moench) Voss) plantations across the boreal.

BSP) provenance trials established from to Population response functions based on February minimum temperatures were developed for 23 Ontario and Great Lakes states provenances to predict climate values maximizing height growth for individual seed sources.

Response of height growth of red pine (Pinus resinosa Ait.) to changes in climatic conditions was analyzed using data collected in a year-old provenance trial established in northwestern Ontario, sources for the trial were collected from 23 provenances spanning the natural range of red pine.

Mean monthly values of climatic variables were estimated from. Siberian larch provenance trial on three locations in Sweden — survival and height growth after four growing seasons.

In LARIX International Symposium of the IUFRO Working Group S (Larch Breeding and Genetic Resources), Saint-Michel-des-Saints and Québec City, September 16–21, As you can imagine, provenance testing is very expensive long-term research, and comprehensive trial series are only possible for the most valuable forest tree species in Alberta: white spruce, black spruce, lodgepole pine, tamarack, and aspen.

Provenance and Climate Data. Black spruce provenance data was obtained from remeasurements on a portion of the Canadian Forest Service’s (CFS) long-term black spruce provenance trial, which originally incorporated seed sources across 34 test sites in Canada and the United States (see Selkirk 50 for details).

Provenances are a mixture of putative white spruce, Engelmann spruce and hybrids of the two species. This provenance trial is replicated at 15 sites in British Columbia, two sites in Alberta and one site in the Yukon Territory. All trials were established in Use of Provenance tests to Predict Response to Climatic Change: Loblolly Pine and Norway Spruce Article (PDF Available) in Tree Physiology 14(7_9).

Research Highlights: In this study, we found different regulatory mechanisms in two contrasting provenances of Norway spruce responding to progressive drought stress.

Background and Objectives: In the context of climate and environmental changes, the following question of high importance in scientific studies is: How will Norway spruce, which forms a dominant.

1. Introduction. Black spruce is an economically important tree species which is widely distributed in the western Canadian boreal forest (Pojar, ).Black spruce grows under a broad range of environmental conditions and latitudes (Burns and Honkala, ), ranging from sea level to m (Groot and Horton, ) and can endure extreme stress (Belien et al.

Provenance research should be given highest priority at the outset of any program of forest tree improvement. Provenance research means many things to many men. [Some data on the international spruce provenance trial in Sweden].

Skogen,Wood density and seed source in young plantation red pine. For., A debt of gratitude is owed to the generation of forest geneticists that established and measured the wealth of black spruce provenance tests. The Canadian Forest Service generously provided access to unpublished data for the regional Newfoundland and range-wide Maritimes provenance.

A prototype spruce-only provenance trial on an adjacent patch gives a preview of how some of these seedlings might look in five years. A few are about chest height, others are half or a quarter as.GENERAL BOTANICAL CHARACTERISTICS: Norway spruce is an introduced evergreen tree.

In central Europe, heights of up to feet (61 m) have been reported []; the range is usually between and feet ( m) [].The bole is usually straight and symmetrical, with no tendency to fork [].The bark of young trees has pale fine shreds [].The bark of older trees is.

Hybrid white spruce and lodgepole pine seeds were obtained from the BC Ministry of Forests Tree Seed Centre, Surrey, BC, Canada and originated from sites located in the West Chilcotin region (Hybrid white spruce – 51° 57′ N lat., ° 59′ W long., elevation m, SBPSxc biogeoclimatic zone; Lodgepole pine – 51° 54′ N lat.,
