“…It is necessary to consider the impact of logging equipment on the restoration of post-harvest soil, ground cover and woody vegetation. Each of these elements plays a significant part in the structural organisation and functional abilities of forest ecosystems (Cambi et al 2015, Smirnova et al 2017, Dymov 2017. In order to prevent potentially damaging post-harvest environmental processes, logging operations on soil with excessive or temporarily excessive moisture must undertake specific measures.…”

Biogeosciences and Forestry Biogeosciences and Forestry The natural recovery of disturbed soil, plant cover and trees after clear-cutting in the boreal forests, Russia Aleksey Ilintsev (1-2) , Alexander Bogdanov (1-2) , Elena Nakvasina (2) , Irina Amosova (3) , Sergey Koptev (2) , Sergey Tretyakov (2) This study aims to determine the impact of forest harvesting machinery on the temporarily moist soil of spruce forests (Picea abies Karst.) during the summer. For research purposes, we investigated 23 sites of the boreal forest in the European North of Russia (Arkhangelsk region) where logging operations had been carried out using harvesters and forwarders (CTL, cut-to-length harvesting). In the 15 years after logging, the sites were monitored for changes in physical soil properties and the depth/width of ruts and vegetation. In freshly cut areas, the depth of the ruts was linked to the amount of logging residue that had been used to strengthen skidding trails. After 15 years, the ruts were smooth but had not disappeared entirely. The average depth of the ruts decreased from 36 cm to 18 cm during the period under review. At a depth of 0-10 cm, the soil bulk density of the section between the control area and the wheel track increased by 19-27% within the first two years. At a depth of 10-20 cm, the soil bulk density only increased by 16-17% within the two-year period. After 15 years, the soil bulk density had decreased to the extent that there were no signs of heavy machinery movement. The natural restoration of vegetation in the ruts was affected by the presence of stagnant water in the initial post-logging period. Ruderal species and species with broad ecological amplitude to environmental factors grew over the skid trails. 15 years after logging, this overgrowth had stabilised, with the biodiversity level in the control area approaching its pre-logging state. Primarily, the renewal of the cutting areas occurred through species such as birch (Betula pendula Roth.) and aspen (Populus tremula L.). The highest amount of undergrowth (more than 30,000 ha-1) was detected 6-8 years after logging. This then decreases in areas that were cut down earlier. There are environmental consequences of clearcutting (using the CTL system) on temporarily moist soil. To prevent the formation of deep ruts, it is recommended to leave 15-20 kg m-2 of felling residue.

“…Nowadays, Quercus robur individuals are more than 300 years old, while the maximum age of other tree species is more than 150 years. The cover of the overstorey is 60%, and the average cover of the shrub layer is 40% (Smirnova et al, 2017). Corylus avellana L. often dominates the shrub layer; estimates of entire individual shrubs age are more than 200 years, while the age of stems of a shrub are more than 50 years.…”

“…Furthermore, old-growth forests serve as an archive of past events allowing a better understanding of mechanisms of natural development after disturbances and successional dynamics of forest ecosystems (Kuuluvainen & Aakala, 2011;Král et al, 2014). The peculiarities of such forests are the abundant deadwood, presence of trees of various ages and diameters resulting from natural regeneration, numerous large and old trees, and a complex canopy structure consisting of multiple layers and heterogeneous mosaic of patches (Smirnova et al, 1988(Smirnova et al, , 1989(Smirnova et al, , 1990(Smirnova et al, , 2017Franklin & Van Pelt, 2004). A number of studies over the past two decades have shown that the proportion of old-growth forests has rapidly decreased across the world (Shorohova et al, 2011;Sabatini et al, 2018;Spracklen & Spracklen, 2021), whereas many of such forest tracts are still poorly studied.…”

The article provides primary data on repeated tree measurements collected during two censuses on a permanent sampling plot (440 m × 200 m) established in the old-growth polydominant broad-leaved forest in the Kaluzhskie Zaseki State Nature Reserve (centre of European Russia). The time span between the inventories was 30 years, and a total of 11 578 individuals of ten tree, one shrub species, and several undefined tree species of three known genera were registered. During the surveys, tree identity, stem diameter at breast height (DBH) of 1.3 m, and life status (alive or dead) were recorded for every tree individual with DBH ≥ 5 cm. Additional attributes were determined for some individuals. Field data were digitised and compiled into the PostgreSQL database. An accurate data quality assessment, validation, and cleaning (with documentation of changes) have been performed before data standardisation according to the Darwin Core standard. Standardised data were published through the GBIF repository. From 1986 to 1988, 9811 individuals were recorded within the initial census, including 3920 Corylus avellana individual shrubs. Corylus avellana shrubs were recorded without measuring DBH. From 2016 to 2018, 7658 stems were recorded in the recensus, including 3090 living trees marked during the initial census, and 1641 other living trees reaching the DBH of at least 5 cm. Corylus avellana was not included in the recensus. Thus, over 30 years, about 65% of living tree individuals have survived, but the total number of living trees has not changed considerably. The mean diameter of shade-intolerant tree species (Quercus robur, Fraxinus excelsior, Populus tremula, and Betula spp.) has increased the most remarkably during 30 years. For these species, the increase in average diameter, along with the decrease in numbers, is associated with the death of young trees, presumably due to low illumination under the canopy. Contrastingly, shade-tolerant tree species (Ulmus glabra, Tilia cordata, Acer platanoides) increased in number, while their mean diameter increased slightly or even decreased, that evidences the successful regeneration of these species under the canopy. These data are relevant for investigating forest ecology questions at spatiotemporal scales as a model of natural succession.

“…In the absence of external disturbances, a climax community is able to keep its own optimal environment stable for infinitely long periods of time [ 35 , 77 ]. For instance, many of the rarest hemi-boreal forest species are associated with ancient trees that still remain and can be tracked through time to a continuous cover of old trees [ 38 , 39 ]. Thus, understanding the biological legacies produced by natural disturbances and succession is crucial towards reaching sustainable forest management for both conservation and wood production [ 80 ].…”

Developing forest harvesting regimes that mimic natural forest dynamics requires knowledge on typical species behaviors and how they respond to environmental conditions. Species regeneration and survival after disturbance depends on a species’ life history traits. Therefore, forest succession determines the extent to which forest communities are able to cope with environmental change. The aim of this review was to i) review the life history dynamics of hemi-boreal tree species in the context of ecological succession, and ii) categorize each of these tree species into one of four successional development groups (gap colonizers, gap competitors, forest colonizers, or forest competitors). To do this we embraced the super-organism approach to plant communities using their life history dynamics and traits. Our review touches on the importance and vulnerability of these four types of successional groups, their absence and presence in the community, and how they can be used as a core component to evaluate if the development of the community is progressing towards the restoration of the climatic climax. Applying a theoretical framework to generate ideas, we suggest that forests should be managed to maintain environmental conditions that support the natural variety and sequence of tree species’ life histories by promoting genetic invariance and to help secure ecosystem resilience for the future. This could be achieved by employing harvesting methods that emulate natural disturbances and regeneration programs that contribute to maintenance of the four successional groups.
