“…Conducting experiments on large scales is expensive and time-consuming (Peterson and Anderson 2009). It was therefore not surprising that the ecological studies that relied on experiments were conducted on a stand scale.…”

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.

“…Especially, seedlings of broadleaf tree species can appear and grow as understory vegetation in a thinned plantation of coniferous species, and can also promote ecological succession (Son et al 2004;Kang et al 2014). In other studies, the influence of forest management, especially thinning, on understory vegetation has been evaluated by using short-term approaches (Nelson et al 2007;Peterson and Anderson 2009), chronosequence approaches (Puettmann and Berger 2006), retrospective studies (Bailey et al 1998;Lindh and Muir 2004), and the Density Management Study (DMS) (Cissel et al 2006;Peterson and Anderson 2009).…”

The study was conducted to analyze the effects of thinning intensity on understory vegetation in Chamaecyparis obtusa stands. The site was located on Mt Moonsu in Gochang-gun, South Korea and consisted of five treatment plots: 5 m £ 5 m quadrats were installed in each plot. The total flora of the C. obtusa stand included 47 families, 60 genera, and 70 species. Three classes of floristic regional indicator plants were verified: six taxa in class I, one taxon in class II, and one taxon in class III. Also, Phytolacca americana and Robinia poseudoacacia appeared as naturalized plants in heavy thinning and control plots, respectively. Their Naturalized Index and Urbanization Index were shown as 1.00% and 0.74%, respectively. Within the treatment plots, the greatest number of species appeared in the heavily thinned plots (31 species). Chamaecyparis obtusa showed the highest dominance index of 4.67. Regarding species richness of understory vegetation, there was a very distinct difference between the thinned and non-thinned plots, whereas there was no significant differences among the treatment plots such as light thinning, normal thinning, heavy thinning, and super heavy thinning plots. Thus, understory vegetation was influenced by the presence of thinning, but not influenced by thinning intensity in this study.

“…Similarly, large experiments are expensive to measure, which can lead to irregular measurement periods or possible delays in harvest if funding is not available. However large scale experimental studies are required to help understand new or novel manipulations of habitat required to sustain natural intact plant and animal populations and forest structure [19].…”

“…The DEMO study in Oregon and Washington, USA has 36 replicates (6 blocks and 6 treatments per block (uncut, 15% dispersed, 40% dispersed, 15%, 40% and 70% aggregated)) although there was no dedicated clearcut control [19]. The MASS study in BC Canada has three levels of VR treatment, an uncut and clearcut control yet the uncut control and clearcut were not truly randomized in the design [9,20].…”

“…As part of the management rationale for the experimental sites, five percent dispersed tree retention was arbitrarily set as the minimum retention needed to maintain some forest structure on site [17], while 15% dispersed retention was considered by expert opinion a minimum for the provision of sufficient habitat for maintaining some forest organisms [14]. Fifteen percent is also the minimum retention level for the U.S. Forest Service Northwest Forest Plan [18,19]. Thus, the focus for the smaller sites (TM128, LL55) was at the minimum for structure (5%) and habitat (15%) while the larger site (TM188, part of a series of different Adaptive Management and Monitoring (AMM) retention experiments) considered a wider range of dispersed retention: 5%, 10% and 30%.…”

Three large-scale, experimental, dispersed residual tree sites established in coastal British Columbia, Canada were measured for planted Douglas-fir tree growth and survival five to six years after planting. The dispersed trees were predominantly large diameter (60 cm+) Douglas-fir left with a range of 0% to 30% of the original forest stand basal area (0 m ). Two sites had 0%, 5% and 15% retention, while one site had 0%, 5%, 10% and 30% retention. The trees were measured in sector plots established to randomly sample the range of microsites in each treatment. There was no detectable difference between height and basal diameter growth or mortality rates between the retention treatments over the measurement period, except for a reduction of basal diameter growth at the 30% retention level (p < 0.05). Thus a statistically significant impact on growth was demonstrated for the 30% retention compared to the 0% retention level. We expected intermediate growth rates between the 0% and the other lower retention levels but were unable to demonstrate this due to the low statistical power of the test (10 observations) and high site variability for these very young trees.
