There are concerns about the effect of increasing resource extraction and other human activities on soils vegetation boreal zone. The review covers published papers between 1974 2012 to assess effects natural disturbances tree nutrition growth Canadian Changes in soil foliar nutrients following disturbance were also analyzed by meta-analysis. When sufficient replicated studies not available for a given or nutrient, response assessments narrative summaries presented. majority fertilization...
Global forest area is declining rapidly, along with degradation of the ecological condition remaining forests. Hence it necessary to adopt management approaches that can achieve a balance between (1) human designs based on homogenization structure efficiently deliver economic values and (2) naturally emerging self-organized ecosystem dynamics foster heterogeneity, biodiversity, resilience adaptive capacity. Natural disturbance-based suggested provide such an approach. It grounded premise...
Abstract Changing climates are altering the structural and functional components of forest ecosystems at an unprecedented rate. Simultaneously, we seeing a diversification public expectations on broader sustainable use resources beyond timber production. As result, science art silviculture needs to adapt these changing realities. In this piece, argue that silviculturists gradually shifting from application empirically derived silvicultural scenarios new sets approaches, methods practices,...
Plant species distribution and plant community composition vary along environmental gradients. At the continental scale, climate plays a major role in determining distribution, while at local regional scales vegetation patterns are more strongly related to edaphic topographic factors. The projected global warming alteration of precipitation regime will influence tree physiology phenology, is likely promote northward migration species. However soil characteristics on not as well understood....
The growing demand for bioenergy feedstock from forest harvest residues is generating concerns about the potential loss of site productivity through nutrient removal. We used tree-level national biomass equations and a database plots to develop stand-level different tree components 30 major species found in Canada using basal area as independent variable. have also compiled more than 12 800 concentration values Canadian existing databases literature. Uncertainties were propagated across...
To describe and compare the factors that impact initial rehabilitation type after hip fracture surgery. Retrospective population-based cohort study. People aged between 50 105 with a who had surgical repair in Ontario, Canada, January 1, 2015, December 31, 2021. Descriptive statistics multinomial logistic regression model were used to identify associated type. In this study, 63,401 individuals included mean age of 80 years (standard deviation [SD] 10.9), mostly female (67.3%), 86.3% living...
Over the past two decades, partial harvesting has been increasingly used in boreal forests as an alternative to clearcutting promote irregular stand structures and maintain a balance between biodiversity preservation continued timber production. However, relatively little is still known about silvicultural potential of Canada’s forest, especially areas prone organic matter accumulation (paludification), most prior research focused on responses. In this study, we assess effects development...
<ja:p>It has been suggested that without sufficient soil disturbance, harvest in boreal forested peatlands may accelerate paludification and reduce forest productivity. The objectives of this study were to compare the effects methods (clearcutting vs. careful logging) season (summer winter harvest) on black spruce regeneration growth eastern Canada, identify variables favour tree following harvest. Moreover, we sought determine how stand compared with observed fire. average height summer...
Canada's boreal forest represents an important contributor of the world's wood supply industry. However, maintaining or increasing productivity may be challenging in areas dominated by forested peatlands. Moreover, sustainable management these forests must also consider other aspects ecosystem such as biodiversity and carbon sequestration. To address concerns, ecosystem-based has been implemented some Canadian jurisdictions, regions where a large portion is The objectives this paper are (1)...
Short-rotation intensive cultures (SRICs) of willows can potentially sequester carbon (C) in soil. However, there is limited information regarding the factors governing soil organic C (Corg) accumulation following afforestation. The objectives this study were to: (i) determine whether willow leads to Corg topsoil (0–10 cm) two six years after establishment five SRICs located along a large climatic/productivity gradient southern Quebec, and (ii) assess influence leaf litter decomposition...
Forest inventory mapping is used worldwide to describe forests at a large spatial scale via the delimitation of portions landscape that are structurally homogeneous. Consequently, there significant amount descriptive forest data in maps, particularly with development ecosystem classification, which represents potential for use based management. With this study we propose test whether maps can be not only stand characteristics but also dynamic processes. The results indicate types...
Successional paludification, a dynamic process that leads to the formation of peatlands, is influenced by climatic factors and site features such as surficial deposits soil texture. In boreal regions, projected climate change corresponding modifications in natural fire regimes are expected influence paludification forest development. The objective this study was forecast development paludified forests northeastern North America relation regime for period 2011–2100. A index built using static...
Machinery traffic restrictions during forest harvest have been adopted to minimize soil damage and protect tree regeneration. However, this practice is questioned for paludifying black spruce ( Picea mariana (Mill.) BSP) stands in which severe disturbance by wildfire restores productivity. The objective of study was determine, 8 years after harvest, how created clearcutting careful logging affected natural regeneration growth effect varied type. While density higher following logging,...
