Variable retention forestry in European boreal forests in Russia
- 276 Downloads
We explored whether, and to what extent, variable retention (VR) forestry has been applied in European boreal forests in northwestern Russia. Our survey revealed VR since 1910. Between 1910 and the 1960s, the statistics showing how much was retained are largely missing. However, for example, in the 1950s, on a large scale in the Republic of Karelia, up to 200-ha-sized harvesting areas, 18–33%, were retention patches with a mean growing stock of 30–40 m3 ha−1. In the fellings defined as “incomplete clear fellings,” which were the most common final felling type at that time, 11–40% of the growing stock was left. Between the 1960s and the early 1990s, with more efficient harvesting and skidding techniques, conventional clear fellings with a much lower amount of retention were practiced. Concern about the regeneration of harvested areas gradually led to smaller (maximum 50 ha) harvesting areas and the increase of silvicultural activities. Until now, to ensure natural regeneration, patches of understory and 20–25 seed trees (i.e., ca. 15–25 m3) per ha have been left permanently in harvesting areas. Landscape-scale retention for protecting ecosystem functions and biodiversity was legislated in 1978 by preserving key biotopes up to 1000 ha in size. Since 2001, promoted by forest certification, the key biotopes, such as paludified forest patches, buffers around water bodies, and habitats of red-listed species, have also been retained in harvesting areas, together with a dispersed retention of different elements. Quantitative estimates of the amount of key biotopes are largely missing. However, estimates of 1–13% in harvesting areas and 23% in whole managed landscapes have been given. VR applied during the last century has emulated natural disturbances and created diverse uneven-aged forest structures with high amounts of diverse coarse woody debris. We conclude that an analysis of past and current retention practices is essential for estimating the global role of Russian forestry. Further decisions on the general direction of Russian forestry and, specifically, retention practices are important to address the global challenges of biodiversity loss and climate change.

Coarse woody debris
The forests of the Russian Federation account for more than 20% of the planet’s forest estate (The Russian 2012). They provide multiple ecosystem services, including timber production, biodiversity conservation, and climate change mitigation (Shvidenko et al. 2007; Gauthier et al. 2015; Lukina et al. 2015; Bukvareva and Zamolodchikov 2016). Thus, analyzing Russian forestry practices is essential for resolving global forest sustainability issues.
Variable retention (VR) forestry introduced in northwestern (NW) North America in recent decades to prevent the rapid ongoing degradation and simplification of forests and to address the need to better integrate wood production and biodiversity (Franklin 1989) has been widely adopted (Gustafsson et al. 2012; Lindermayer et al. 2012). Russian forestry has not yet been critically evaluated from perspectives of retention practices. In fact, even the concept of VR has not been discussed much in Russia. Here, we present an overview of the forest management treatments in NW Russian forests in the past and present that can be regarded as VR and discuss their global impact on biodiversity and ecosystem services. Finally, we speculate about future perspectives of retention forestry in Russia.
NW Russian forests: a retrospective view
Forest resources and their use
NW Russia represents a key area for satisfying rival forestry objectives containing economically important forest resources (Melnikov 2011), as well as the largest European boreal old-growth forests (Aksenov et al. 1999). Forests in NW Russia cover 53% of the land area, of which the share of commercial forests is 62% (Federal 2019). Forests with restricted or totally forbidden forestry activities occupy 38%. The dominant tree species are Norway spruce (Picea abies L., Karst.), Scots pine (Pinus sylvestris L.), birch (Betula pendula Roth. and B. pubescens Ehrh.), and aspen (Populus tremula L.) (Regional 2017, 2018).
In NW Russia, the history of significant human influence on forests has started in the fifteenth to sixteenth centuries, when forests were impacted by selective logging for firewood, production of tar, potash, and salt and later for large diameter trees to supply Peter the Great’s shipbuilding (Dekatov 1961; Redko 1981; Fedorchuk et al. 2005; Sokolov 2006). Cuttings were made in winter time with a two-man cross-cut saw and a horse skidding. Slash and burn cultivation was widely applied in the beginning and in some places even until the middle of the twentieth century (Kozubov and Taskaev 2000; Fedorchuk et al. 2005; Sokolov 2006).
At the end of the nineteenth century, selective logging was concentrated around settlements and industrial centers (Kozubov and Taskaev 2000; Sokolov 2006). Large-scale, “concentrated” clear felling with harvesting areas of 50–100 ha in size and, in practice, even up to 1000 ha (Aksenov et al. 1999; Kozubov and Taskaev 2000; Fedorchuk et al. 2005) was practiced after the Second World War (Sokolov 2006). Fellings had an unsystematic character, i.e., they were not properly planned either in size or in time (Fedorchuk et al. 2005; Sokolov 2006).
Between the 1960s and the early 1990s, with more efficient harvesting and skidding techniques, practicing incomplete clear felling gradually ceased and was replaced by conventional clear felling. Concern of poor conifer regeneration and the increased share of deciduous forests (see Sokolov 2006, for literature review) progressively led to smaller (maximum 50 ha) harvesting areas. In the period between 2000 and 2013 in the FSC (Forest Stewardship Council)-certified NW Russian forests, the size of clear-cut areas varied from 7.6 to 25 ha with the mean value of 10 ha (Ilina and Rodionov 2017). Since the 1990s, selection felling has become more common. After 2000 in NW Russia, the share of selection felling varied across regions from 2 to 58% with the mean value of 22% (Annual 2012).
Nature conservation: protected areas and special forest management categories
Different functions of forests (protective, conservation, cultural, commercial) were acknowledged in national forest law in 1923 (Forest Code 1923) and formed the basis for classifications of forests into forest management categories (The Act 1943; Bajtin et al. 1974; Nikolayuk et al. 1977; National 2003; Forest Code 2007). At present, the first forest management category, where clear fellings are forbidden, consists of protective forests of special environmental, scientific, historical, or socio-cultural values. This category includes forests in protected areas, protective buffer zones along water bodies, shelterbelts by roads and railways, sites of high conservation value, urban forests, etc. In NW Russia, the share of protective forests in the forest estate is 38%, varying from 15% in the Vologda region to 64% in the Murmansk region (Fig. 4). According to the Forest Code and Water Code, the width of forest buffers along water bodies can reach up to 3 km (Leman et al. 2018). This sub-category of protective forests requires special attention in planning forestry activities (Ananyev and Sinkevich 2015), which is especially important to the Republic of Karelia, where the share of these forests (18%) is the highest among the regions (Fig. 4). The majority of forest estate belongs to the second category and is used for commercial purposes (Fig. 4). The forests of the third category are “reserve” forests that are not planned to be harvested in the near (more than 20 years) future.
Protection of key biotopes (osobo zaschitnye uchastki in Russian) has started in 1978 on a state level and was legalized in forest management plans. The list of key biotopes has included, for example, forest buffers along small water bodies and ravines, forest edges, habitats of red-listed, endemic, and relict species and fragments (100–150 ha) of old-growth forests. The habitats of rare species and fragments of old-growth forests are completely excluded from harvesting. Clear felling is forbidden in all types of key biotopes.
Since 2001, the biodiversity conservation has been actively incorporated into forest management following forest certification criteria (Aksenov et al. 2000; Romanyuk et al. 2001; Yanitskaya, Shmatkov 2009; Yanitskaya 2010; Shmatkov 2013a, b) and promoted on a state level (Regulations 2016b).
The majority of forests in NW Russia has been developed through natural regeneration. The attributes of intensive forest management in, for example, neighboring Fennoscandian countries include clear felling with ten retention trees per ha (Vanha-Majamaa and Jalonen 2001; Gustafsson et al. 2012), followed by site preparation, planting of trees, multiple thinnings during the rotation period, and final clear felling (Finnish 2018). In Russia, until now, these forestry treatments have been implemented in practice only sporadically (Knize and Romanjuk 2004; Sokolov 2006).
Since 1923, prescribed burning for the “clearing” of harvested areas and enhancing natural regeneration was used (Tkachenko 1931). For example, in the Republic of Karelia, it was done in ca. 8% of harvested areas (Davydov 1934). Later, it was replaced by partial burning (Sokolov 2006) and finally forbidden in 1993 to reduce fire risks. Currently, only logging slash piles are allowed to be burned. Since the 1940s, treatments ensuring successful forest regeneration a wiz: retaining seed trees, saving existing understory, sowing tree seeds, and lately, to some extent, planting have been applied in practice (Dekatov 1961; Kozubov and Taskaev 2000; Sokolov 2006). Soil preparation methods have been developed from manual to tractor scarifier or disk trencher and lately, but rather seldom, mounding has been applied. Until recently, however, the annual area of soil preparation has not exceeded 25% of the regeneration area (Sokolov 2006). Planting was carried out manually earlier with seedlings with an open root system and later with partly mechanized planting of container-grown seedlings (Sokolov 2006). Nowadays, according to state-level regulations for forest regeneration (Regulations 2016a), methods of forest regeneration depend on the condition of the harvesting area (site conditions, the amount of viable seedlings, young and middle-aged trees, uncut patches, stumps, logs and logging slash, cover of grasses). In contrast to, for example, Finnish practice (Finnish 2018), where individual seed trees (20–100/ha) are later harvested after seedling establishment, in most cases in Russia, the 20–25 seed trees per ha are left permanently in the harvesting area so that the distance between the groups does not exceed 100 m (Regulations 2016b). The seed trees can potentially be cut during the first thinning (Regulations 2017). However, intermediate fellings in Russia are still rather rare (Tikhonov and Zyabchenko 1990; Chibisov et al. 2004), which leads to self-thinning and promotes additional coarse woody debris (CWD) inputs during forest succession. In Russia, stumps, tree tops, and other logging residues are typically left in harvesting areas (Ivanov et al. 2009), in contrast to, for example, Fennoscandia, where soil preparation and bioenergy removal have been widely practiced (Hautala et al. 2004; Rabinowitsch-Jokinen and Vanha-Majamaa 2010).

The key biotopes and elements preserved in NW Russian harvesting areas are rather similar to woodland key habitats in Fennoscandian (Sweden, Finland, Norway) and Baltic (Latvia, Estonia, Lithuania) countries (Timonen et al. 2010). The main types include, for example, forest patches around peatlands, small lakes, and springs; uneven-aged forest patches; gaps after windthrows; regionally rare tree species; old trees; trees with bird nests and hollows; snags; high stumps, and large (e.g., in the Arkhangelsk region, more than 25 cm in diameter) downed deadwood of different decay classes (Table 1).
Quantitative estimates of past and present retention are largely missing. In the middle of the twentieth century, the level of retention from incomplete felling in NW Russia varied greatly: from 1 to 146 m3 ha−1, or 1–83% of the growing stock (Sakhovets 1977). Within a harvesting area, 18–33% was left uncut on average, and the growing stock of an uncut patch averaged 30–40 m3 ha−1 (Baranov 1954; Marjin 1957). There is no precise data on the amounts of seed trees retained in harvesting areas. However, the volume of seed trees per ha (Federal state statistics 2019; Fedorchuk et al. 2005; Finnish forest statistics 2018; Forest Code 1923; Forest Code 2007; Forest regeneration in 2016, 2017) can be estimated, based on forest mensuration data by tree species (Tetioukhin et al. 2004), to be 15–25 m3 ha−1 for spruce and pine respectively. The volumes of CWD in harvesting areas average 30 m3 ha−1 (Galaktionov 2008). However, in some cases, they can exceed 100 m3 ha− 1 (Kapitsa et al. 2019).
Evidence on the amount of key biotopes and elements is scarce. According to the information provided by ten FSC-certified forest companies for the period 2005–2014, the area of key biotopes inside clear-cut areas varied from 1 to 13% with a mean value of 6% (Ilina and Rodionov 2017). However, most key biotopes are protected outside the areas planned to be harvested (Ilina and Rodionov 2017). For example, the area of key biotopes in harvesting areas in the Pskov model forest averages 10% (Zagidullina, pers. com), whereas the total area of key biotopes comprises 23% of all Pskov model forest land (Bublichenko 2004). In the Pryazhinskoye and Kondopozhskoye forest management areas (lesnichestvo) in the Republic of Karelia, 12% of the mature forest area are key biotopes (Sinkevich, unpublished).
Studies on the impact of VR on biodiversity and ecosystem functions are scarce in Russia. However, some studies have demonstrated the positive role of uncut forest patches for forest regeneration (Asoskov 1940; Kischenko, Vilikainen 1957; Marjin 1957; Melekhov 1966) and preserving forest microclimate and environment, preventing paludification, and consequently providing important ecosystem functions (Yaroshenko 2005). Uncut patches, together with seed tree groups and patches of understory left permanently in the harvesting areas, form a natural refuge for biodiversity in managed landscapes (Kravchenko 1999; Volkov et al. 2002; Kravchenko et al. 2004; Kryshen 2006; Gromtsev et al. 2010; Ivanter and Kurhinen 2016; Fadeeva and Kravchenko 2018).
Gaps in knowledge and future perspectives of VR in Russia
Information about forest resources and forestry practices in NW Russia is the most complete, compared to other parts of Russia. However, statistics of what has been actually left unharvested and where are still largely missing even in NW Russia. A systematic inventory reviewing the amounts, patterns, and quality of retention in spatio-temporal dynamics would provide more robust information of current forest structures in NW Russia. The long time period of clear felling, but with high retention levels, provides the unique possibility to evaluate the long-term impact of VR forestry on biodiversity and forest dynamics, since the species richness of different taxonomic groups changes with time following harvest (Fedrowitz et al. 2014). Information on retention practices and a magnitude of soil preparation after harvesting would improve the assessment of the role of Russian forestry in climate regulation (Pohjanmies et al. 2017) and provide a better understanding of the mechanisms of forest management impact on ecosystem resilience under climate change (Chapin et al. 2007; Millar et al. 2007).
Recently, increasing wood production according to the so-called Fennoscandian model of intensive forest management (Karjalainen et al. 2009; Karvinen et al. 2006, 2011) is being discussed in Russia. The concept of adaptive management for maximizing resilience and the sustainability of forests under climate change has been recommended as an alternative (Karpachevsky 2007; Nordberg et al., 2013; Chapin et al. 2007; Naumov et al. 2017). This concept suggests further development of selection felling practices and preserving key biotopes and elements in parallel with the research and monitoring of the results of their practical implementation. Its implementation, however, requires overcoming discrepancies between existing forestry regulations and sustainability (Karpachevsky 2007; Yanitskaya and Shmatkov 2009, Shmatkov, 2013a, b; Kulikova et al. 2017; Sinkevich et al. 2018) by taking into account diverse natural and socio-economic conditions across the country with varying legacies from past forestry activities (Shvarts, 2003; Shvidenko and Schepaschenko, 2011; Lukina et al. 2015; Naumov et al. 2017; Sinkevich et al. 2018) (Additional file 1).
Retention forestry in NW Russia has been practiced over a century for varying reasons. The biological legacies left in harvesting areas, either aggregated or dispersed, have emulated natural disturbance patterns and processes and created uneven-aged forests with diverse structures. Thus, the recommendations for sustainable forest management and ecological restoration developed recently in other Fennoscandian or other boreal regions have been applied in NW Russia already for over a hundred years.
Currently, Russian forest policy is at a decisive point in terms of its general direction. Ignoring natural and socio-cultural diversity across regions and concentrating only on maximizing wood production will lead to the risk of losing other ecosystem services. Future decisions concerning retention practices in NW Russian forestry are thus important to a global biodiversity and climate change mitigation.
