In scenarios of future climate change, there is a projected increase in the occurrence and severity natural disturbances boreal forests. Spruce budworm (Choristoneura fumiferana) (SBW) main defoliator conifer trees North American forests affecting large areas causing marked losses timber supplies. However, impact spatiotemporal patterns SBW dynamics at landscape scale over last century remain poorly known. This particularly true for northern regions dominated by spruce species. The goal this...
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,...
Partial cutting is thought to be an alternative achieve sustainable management in boreal forests. However, the effects of intermediate harvest intensity (45%–80%) on growth remain unknown black spruce (Picea mariana (Mill.) B.S.P.) stands, one most widely distributed species with great commercial interest. In this study, we analysed effect three experimental shelterwood and seed-tree treatments tree radial even-aged 10 years after intervention. Our results show that response 8–10 was 41% 62%...
Forest ecosystem management heads towards the use of partial cuttings. However, wide variation in growth response residual trees remains unexplained, preventing a suitable prediction forest productivity. The aim study was to assess individual and identify driving factors involved responses trees. Six blocks even-aged black spruce [Picea mariana (Mill.) B.S.P.] stands eastern Canadian boreal were submitted experimental shelterwood seed-tree treatments. Individual-tree models applied 1039...
Partial cutting has been recommended as an alternative harvesting method to ensure the sustainable management of boreal forests. The success this approach is closely linked survival residual trees additional losses through mortality could affect post-cutting timber production at harvest. To better quantify in previously unmanaged forests, we addressed two main questions: (1) what level ten years after cutting? and (2) ecological factors are involved phenomenon? Even-aged black spruce [Picea...
Forest regeneration is a key element in achieving sustainable forest management. Partial harvest methods have been used extensively temperate broadleaf and mixedwood ecosystems to promote on poorly stocked sites maintain composition productivity. However, their effectiveness promoting conifer establishment has yet be demonstrated unmanaged boreal forests, especially those dominated by black spruce (Picea mariana (Mill.) BSP) where constraints for differ from found more meridional regions. We...
Traditional clear-fell forestry greatly alters community structure and ecosystem function within boreal forests alternative management practices may reduce these impacts. Continuous-cover can maintain similar invertebrate plant communities to unmanaged forest, but whether this extends soil fungal remains unclear. Within four sites across the mid-boreal zone of Sweden, we conducted a comprehensive study assess impact continuous-cover clear-felling on fungi chemical properties Norway spruce...
<title>Abstract</title> Young plantation trees are often highly vulnerable to insect herbivory in ways that difficult predict as underlying mechanisms linked plant traits and natural enemy pressure interact context-dependent ways. We compared bottom-up top-down forces acting on spruce budworm (<italic>Choristoneura fumiferana</italic>) young white (<italic>Picea glauca</italic>) plantations vs regeneration under hardwood canopy. Recognized the most important outbreaking conifers defoliator...
Spruce budworm (Choristoneura fumiferana) is the main defoliator of conifer trees in North American boreal forests, affecting extensive areas and causing marked losses timber supplies. In 2017, spruce affected more than 7 million ha Eastern Canadian forest. Defoliation was particularly severe for black (Picea mariana (Mill.) B.S.P.), one most important commercial Canada. During last decades, intensive forest exploitation practices have created vast stands young balsam fir (Abies balsamea...
Natural disturbance is one of the major topics in ecology. However, most paleoecological studies have only considered influence wildfire as an agent disturbance, with fire history based primarily on use charcoal a proxy for events. The frequency and intensity insect outbreaks their effect forest landscape been neglected due to absence effective tool. Finding indicators able provide insight into impacts past therefore essential. Fossil moth (Lepidoptera) wing scales offer new approach...
Forest harvesting and fire are major disturbances in boreal forests. has modified stand successional pathways, which led to compositional changes from the original conifer-dominated forests predominantly mixed hardwood Boreal regimes expected change with future climate change. Using LANDIS-II spatially explicit landscape model, we evaluated effects of forest management scenarios projected under northeastern Canadian forests, determined subsequent alteration stand- landscape-level...
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...
Ecosystem-based forest management associated with partial harvesting (PH) is intended to balance ecological and economic values of sustainable management. The potential for delayed growth response elevated mortality advance regeneration following PH remains a critical concern, may present barrier more widespread implementation this approach. We used 835 permanent continuous inventory plots examine the rate time course species-specific eight tree species in first fifteen years operational...
Current ecological models predict profound climate change-related effects on the natural disturbance regimes of forests. Spruce budworm (Choristoneura fumiferana) (SBW) is principal insect defoliator in eastern North America, and SBW outbreaks have a major impact structure function Canadian boreal forest, as defoliation leads to decreased tree growth, increased mortality, lower forest productivity. become more severe over last century with changing climate; however, little known about how...
Old-growth forests play a major role in conserving biodiversity, protecting water resources, and sequestrating carbon, as well serving indispensable resources for indigenous societies. Novel silvicultural practices must be developed to emulate the natural dynamics structural attributes of old-growth preserve ecosystem services provided by these boreal ecosystems. The success forest management strategies depends on developing an accurate understanding regeneration dynamics. Our goal was...
Abstract Spruce budworm ( Choristoneura fumiferana (Clem)) is the main defoliator in boreal forest of North America, and its outbreaks have major ecological economic consequences represent a challenge for management. Numerous studies addressed effects this on mature trees, whereas spruce regeneration remain elusive. Furthermore, intensive exploitation practices during last decades left large area Canadian an early development stage. In context, it becomes vital to understand those factors...
