“…or very weak (C. vulgaris) evidence that clear cuts influence pollinator visitation patterns. Such influence was reported by Rodriguez and Kouki [6] for V. myrtillus and V. vitis-idaea. Interestingly, these authors found that the response direction is not universal, and blueberry performance and reproduction were higher in undisturbed sites, whereas lingonberry benefited from disturbance regimes.…”

“…All three species are entomophilous, pollinated by bees and other insects, and can be characterized by generalist pollination systems [4,6,7,[24][25][26][27]. Pollination in C. vulgaris can also occur via wind-dispersed pollen [7].…”

“…In European boreal forests, such species include, e.g., those of the Ericaceae family, especially species of the genus Vaccinium (e.g., V. myrtillus L. and V. vitis-idaea L.), which, together with Calluna vulgaris, are common and abundant elements of boreal ecosystems. Apart from the biological and ecological importance (see e.g., [6,7] and references cited), they provide significant socioeconomic services, in the case of Vaccinium spp. being traditional wild edible forest food in many European countries [8][9][10] and a source of many important nutritional compounds in human diet [11][12][13][14], while in the case of Calluna sylvestris an important forest species in honey production [15].…”

Managed boreal pine forests are subject to regular clear cuts causing significant disturbances to these ecosystems. It is believed that, to some extent, they resemble natural cycles of forest growth, decline, and regeneration and can benefit, e.g., mutualistic relations among plants and pollinators. To study the impact of forest management (clear cuts) on pollinator visitation, we focused on three ericaceous plant species, Vaccinium myrtillus, V. vitis-idaea, and Calluna vulgaris, common elements of pine forest understory. Our observations, conducted in Lithuania, showed that there are no differences among control mature stands and clear cut areas in terms of visitation frequency for all three studied species. However, at least for C. vulgaris, a shift toward fly visits was observed in the clear cut site, showing that open areas are preferred habitats for these insects. Ants constituted an important share of visitors to flowers of V. myrtillus and C. vulgaris, suggesting their important role in reproduction of these plant species.

“…With increased understanding of the relative importance of different disturbance types across the boreal zone, it is now possible to develop practical applications in their integration to forest management (Gromtsev 2002;Kuuluvainen & Aakala 2011;Shorohova et al 2011). So far, NDE has been utilized both in the development of silvicultural systems that better take into account the ecosystem perspective (Hyvärinen et al 2005;Koivula et al 2014;Rodríguez et al 2015;Heikkala et al 2016;Suominen et al 2016), but also as a guide to forest restoration treatments (Kuuluvainen 2002;Similä & Junninen 2012;Halme et al 2013). …”

The degradation and disappearance of natural ecosystems and habitats -including forestsis one of the most important factors behind the current global decline in biological diversity. Since most of terrestrial biodiversity is found in forests, restoration of these ecosystems or their natural characteristics has been proposed as one of the main strategies to counteract global species loss.In this thesis, I examined the ecological effects of forest restoration in disturbancedriven boreal conditions. The applied restoration methods (prescribed burning; creation of canopy gaps; dead wood restoration) used natural forest disturbances as the reference point. Specifically, I focused on the effects that restoration has on tree species composition, ageclass structure, and the amount and diversity of dead wood in forest ecosystems. In addition to examining the changes in these structural attributes, I investigated dead-wood-associated fungal communities in the restored substrates, and assessed whether dead wood restoration could be used to conserve rare and threatened fungal species.Of the examined restoration treatments, the combination of prescribed burning and the creation of canopy gaps was found to be the most promising measure for the restoration of age-class structure and tree species composition in pine-dominated forests. Dead wood restoration -by artificially creating standing and fallen large-diameter dead trees -clearly enhanced the amount of dead wood in both pine and spruce dominated forests. Although dead wood restoration increased the abundance of fungal species in the examined forests, all aspects of the qualitative variation in dead wood was found to be difficult to restore in the short-term, since the restored dead wood was mainly in the initial stage of decomposition. The use of various restoration treatments (e.g. the creation of both standing and fallen dead wood) can compensate for some of the missing variation in fungal communities in the restored substrates.Based on my results, disturbance-based restoration produces promising results by the rapid re-introduction of some of the most important structural attributes that have been lost from forests previously managed for timber production. Although the findings in this thesis show the clear positive effects that restoration has on the re-creation of naturally occurring forest characteristics, it appears difficult to restore all the inherent variability of natural forests. A particular challenge originates from the extended time scale of the natural processes, which have created and maintained the full array of ecological structures in forests, including the generally slow processes of stand succession and wood decomposition. To build a more comprehensive understanding of the potential of forest restoration for the conservation of endangered forest-associated species, a substantially longer monitoring period of restored forests would be useful in future studies.

Intensive forest management, together with fire suppression, have decreased structural complexity and altered dynamics of boreal forests profoundly. Such management threatens forest biodiversity and can reduce the provision of ecosystem services. Although the importance of ecosystem services is widely acknowledged, conservation strategies are hindered by poor knowledge about diversity patterns of service provider species as well as on mechanisms affecting these assemblages at different spatial and temporal scales. In this study, we assessed the effect of disturbance management on forest pollinator communities. To do so, we used a large-scale ecological experiment conducted in the year 2000, where forest complexity was manipulated with different harvest regimes and prescribed fire. Results were consistent with a positive response of pollinators to increasing habitat heterogeneity driven by past disturbances. Harvested sites harbored a diverse pollinator community, and showed higher spatial and temporal turnover in species richness. Conversely, old-growth forest communities were a nested subset of harvested sites and contained half of their total diversity. Variation in community composition (β diversity) was primarily affected by species temporal turnover. Throughout the season, β diversity was controlled by fire and harvesting legacies, which provide environmental heterogeneity in the form of flowering and nesting resources over space and time. Conservation strategies may undervalue ecosystem services in dynamic, naturally disturbance-driven, landscapes when relying solely on undisturbed forests areas. However, maintaining natural dynamics in early successional forests, by emulating natural disturbances at harvesting, hold promise for the conservation of both biodiversity and ecosystem services in boreal forests.
