“…Dead wood can also significantly contribute to soil development by increasing soil fertility of poor sites [151]. In addition, removing dead trees by salvage logging is directly linked to soil drying and compaction, which alters the understory plant species composition, abundance and richness [47]. and species composition.…”

“…The organisms in such a system may become maladapted due to interactive effects of two simultaneous disturbances (e.g., beetle attack and salvage logging) [32]. Moreover, salvage logging creates a homogeneous landscape structure and composition and a reduction in plant species richness and/or diversity [47][48][49][50]. As in most cases post logging (after timber harvest), stand recovery is facilitated through artificial regeneration with planting of nursery-grown tree seedlings.…”

“…are used to facilitate the reforestation of salvage logged stands [45]. Stands developing from salvage-logged areas may thus have a simplified stand structure and composition as well as lower plant species richness and/or diversity as compared to unsalvaged forest left to naturally regenerate [32,[46][47][48][49][50].…”

Abstract:The mountain pine beetle (Dendroctonus ponderosae Hopkins) (MPB) has infested and killed millions of hectares of lodgepole pine (Pinus contorta var. latifolia Engelm) forests in British Columbia, Canada, over the past decade. It is now spreading out of its native range into the Canadian boreal forest, with unknown social, economic and ecological consequences. This review explores the ramifications of the MPB epidemic with respect to mid-term timber supply, forest growth, structure and composition, vegetation diversity, forest fire, climate change, and ecosystem resilience. Research confirms that, in British Columbia, all of these variables are more significantly impacted when salvage logging is used as management response to the outbreak. We conclude that appropriate management in response to MPB is essential to ensuring ecologically resilient future forests and reliable mid-term timber supplies for affected human communities. We highlight knowledge gaps and avenues for research to advance our understanding in support of sustainable post-disturbance forest management policies in British Columbia and elsewhere.

“…Moreover, removal of burned logs and other woody structure can have long-term consequences on forest diversity and productivity. In the eastern Canadian boreal zone, for example, thin, postfire soils are particularly sensitive to compaction and alteration by harvesting equipment (Brais et al 2000), and salvage logging simplifies the biodiversity in ground vegetation (Purdon et al 2004). Other important salvage impacts include the recruitment dynamics of trees that require nurse logs for regeneration and habitat for cavity-nesting birds and other keystone taxa (Harmon et al 1986;Imbeau et al 2001;Nappi et al 2004;Fisher and Wilkinson 2005).…”

Given the increasingly global stresses on forests, many ecologists argue that managers must maintain ecological resilience: the capacity of ecosystems to absorb disturbances without undergoing fundamental change. In this review we ask: Can the emerging paradigm of natural-disturbance-based management (NDBM) maintain ecological resilience in managed forests? Applying resilience theory requires careful articulation of the ecosystem state under consideration, the disturbances and stresses that affect the persistence of possible alternative states, and the spatial and temporal scales of management relevance. Implementing NDBM while maintaining resilience means recognizing that (i) biodiversity is important for long-term ecosystem persistence, (ii) natural disturbances play a critical role as a generator of structural and compositional heterogeneity at multiple scales, and (iii) traditional management tends to produce forests more homogeneous than those disturbed naturally and increases the likelihood of unexpected catastrophic change by constraining variation of key environmental processes. NDBM may maintain resilience if silvicultural strategies retain the structures and processes that perpetuate desired states while reducing those that enhance resilience of undesirable states. Such strategies require an understanding of harvesting impacts on slow ecosystem processes, such as seed-bank or nutrient dynamics, which in the long term can lead to ecological surprises by altering the forest's capacity to reorganize after disturbance.Résumé : Étant donné l'augmentation globale des stress dans les forêts, plusieurs écologistes croient que les gestionnaires doivent maintenir la résilience écologique, c'est-à-dire la capacité des écosystèmes à absorber les perturbations sans subir de changements importants. Dans cette revue, nous nous demandons si le nouveau paradigme de l'aménagement basé sur les perturbations naturelles peut maintenir la résilience écologique dans les forêts aménagées? L'application de la théorie de la résilience exige une articulation minutieuse de l'état de l'écosystème considéré, des perturbations et des stress qui affectent la persistance d'états alternatifs potentiels ainsi que les échelles spatiales et temporelles de la pertinence de l'aménagement. L'application de l'aménagement basé sur les perturbations naturelles, tout en maintenant la résilience, oblige à reconnaître que (i) la biodiversité est importante pour la persistance à long terme de l'écosystème, (ii) les perturbations naturelles jouent un rôle crucial dans la genèse de l'hétérogénéité de la structure et de la composition à de multiples échelles et (iii) l'aménagement traditionnel tend à rendre les forêts plus homogènes que celles qui sont naturellement perturbées et à augmenter les chances de changements catastrophiques inattendus en réduisant la variation de processus environnementaux clés. L'aménagement basé sur les perturbations naturelles peut maintenir la résilience si les stratégies sylvicoles permettent de conserver les ...

“…Another feature of disturbance is the input of coarse woody debris (CWD), which influences the microclimate as well as water and nutrient regimes [147]. Salvage logging may severely deplete the amount of CWD [39].…”

Forest managers are often required to restore forest stands following natural disturbances, a situation that may become more common and more challenging under global change. In parts of Central Europe, particularly in mountain regions dominated by mixed temperate forests, the use of relatively low intensity, uneven-aged silviculture is a common management approach. Because this type of management is based on mimicking less intense disturbances, the restoration of more severe disturbance patches within forested landscapes has received little attention. The goal of this paper is to synthesize research on the restoration of forests damaged by disturbances in temperate forests of Slovenia and neighbouring regions of Central Europe, where uneven-aged silviculture is practiced. Research indicates that active management aimed at favouring mixed uneven-aged forest reduces the risk of disturbance and improves the resilience of stands. Salvage logging may have positive or negative effects on regeneration, much of which is due to the method applied and the quality of work. The most prominent factors that negatively affect restoration are: lack of advanced regeneration and decomposed woody debris, high altitude, steep slopes, dense ground vegetation, and overbrowsing. Planting or sowing should be applied in post-disturbance forests where many negative factors interact and where a high demand for sustainability of forest ecosystem services is present.
