“…This is probably because shade-tolerance has often been considered a pre-requisite for managing forests through selection cuttings (O'Hara 2002). However, it should be noted that such a restriction seems to be unnecessary as unmanaged Scots pine Pinus sylvestris L. forests are known to be typically characterized by uneven-aged or cohort age structures (Shorohova et al 2008;Kuuluvainen and Aakala 2011). Accordingly, Pukkala et al (2009) developed growth models for uneven-aged Scots pine and birch (Betula pendula Roth., Betula pubescens Ehrh.)…”

“…Microclimatic differences between the two management systems could be expected to lead to differences in deadwood decomposition rates, given that the decomposition rates measured in vitro have shown dependence on the temperature and moisture conditions (Shorohova et al 2008). However, contrary to these expectations, after measuring stump decay rates for different treatments, Shorohova et al (2008) concluded that the retention levels in cuttings had no effect on the stump decay rates.…”

They found that while exposure to sunlight following cutting episodes increases, the effects of the subsequent temperature increase are countered by the decrease in substrate moisture (Shorohova et al 2008).…”

Since WWII, forest management in Fennoscandia has primarily been based on even-aged stand management, clear cut harvesting and thinning from below. As an alternative, uneven-aged management, based on selection cutting of individual trees or small groups of trees, has been proposed. In this review we discuss the theoretical aspects of ecology and economics of the two management approaches. We also review peer-reviewed studies from boreal Fennoscandia, which have aimed at comparing the outcomes of uneven-aged and the conventional even-aged forest management. According to a common view the main obstacle of practicing uneven-aged forestry is its low economic performance. However, the reviewed studies did not offer any straightforward support for this view and several studies have found uneven-aged management to be fully competitive with existing evenaged management. Studies on the ecological aspects indicated that selection cuttings maintain mature or late-successional forest characteristics and species assemblages better than even-aged management, at least at the stand scale and in the short term. We conclude that although the number of relevant studies has increased in recent years, the ecological and economic performance of alternative management methods still remains poorly examined, especially for those stands with multiple tree species and also at wider spatial and temporal scales. For future research we advocate a strategy that fully takes into consideration the interdisciplinary nature of forest management and is better connected to social goals and latest theoretical and methodological developments in ecology and economics.

“…It is known that charred wood decomposes very slowly (Hatakka 2001). Over longer periods of time, burnt stumps of pine wood decompose at a slower rate than unburned stumps (Shorohova et al 2008), indicating that the burst in CO 2 evolution directly after a fire may later be cancelled out by other factors. Hence, the combined effects offorest fire on wood decomposition are complex.…”

Increased CO2 evolution caused by heat treatment in wood-decaying fungi

Wood-decaying fungi are regarded as the main decomposers of woody debris in boreal forests. Given that fungal respiration makes a significant contribution to terrestrial carbon flows, it is important to understand how the wooddecaying fungal metabolism is regulated in relation to different environmental conditions and disturbances. In the present study, we investigated the effect of temperature stress on wood decomposition rate in 18 species of wood-decaying fungi, representing a broad range of species-habitat associations. Heat shock duration and temperature were calibrated to match the conditions of a forest fire. We found a general increase in fungal decay rate after heat shock; the response was more pronounced in species associated with fire-prone forests. The underlying mechanism is unclear, but possibly relates to an up-regulation at the cellular level in response to heat shock. Our results show that the decomposition rate of dead wood can be strongly affected by environmental triggers.

Stump harvesting is defined as an intensification of forest management in comparison with stem-only harvesting and removal of tops and branches. It increases soil mixing and the proportion of bare soil. In contrast to earlier hypotheses, stump harvesting was found to reduce emissions of carbon dioxide (CO 2 ), nitrous oxide, and methane in the short term. In the long term, heterotrophic soil CO 2 evolution is reduced. Both model and empirical studies indicate that stump removal can reduce the soil organic carbon (SOC) pool in the short term, but long-term experiments (32-39 years) could not verify any SOC decline. Life cycle assessment studies showed that stumps as fuel resulted in markedly lower emissions of CO 2 into the atmosphere, viewed over a whole forest rotation compared to heating by natural gas and coal. Stump removal does not seem to affect timber production in the next forest rotation and often reduces the infection rate of root rot. It increases the natural regeneration of birch and pine, it can increase nitrate leaching at N-rich sites, and it can increase the number of water-filled cavities where methylmercury is formed. Stump extraction decreases the amount of dwarf shrubs in young clearcuts, but after 1-2 decades, these species are generally recovered. Many species dependent on dead wood are adversely affected by intense stump harvest. Model studies suggest that the risk of species extinction is small when only 10% of the total clear-cut area in the forest landscape is stump harvested, but the risk of extinction rises at increasing extraction intensities.
