“…Prior to logging, we urge that the lichen flora is thoroughly surveyed, and that trees with U. longissima are marked in the field so they are not incautiously cut. Finally, it is important to evaluate how suitable the forest stands are for selective logging (e.g., following Lexerød and Eid 2006), since certain forest conditions may result in increased vulnerability to wind throws.…”

Usnea longissima is a conspicuous circumboreal "beard lichen" draping tree canopies in moist coastal and mountainous forests. It is extirpated in many European and North-American localities, presumably due to industrial forestry and air pollution, but still has a stronghold in parts of Scandinavia and U.S. and Canadian Pacific Northwest. Using a retrospective approach, we reconstructed the stand histories in 24 plots (0.1 ha) of mature Norway spruce (Picea abies) forest stands in Lillehammer, Norway, of which 21 was selected due to the presence of U. longissima. Number of trees with U. longissima present within plots varied from 4 to 37 and number of visible thalli from 12 to 469. The detailed stand reconstructions were done by means of tree-ring analysis of 517 living trees and the size and decay stage of 1423 stumps from logging and 467 dead trees. Total harvested volume during the last 100 years ranged 100-370 m 3 ha -1 (representing 40-350% of the present-day standing volume), and present amount of dead wood ranged 2-87 m 3 ha -1 (1.0-37% of the standing volume). All stands had been selectively logged 2-4 times during the last 100 years, of which 5 stands almost to a clearcut appearance. We used a variety of present-day and historic forest structural variables, both at the scale of study plots and individual trees, to predict the occurrence and abundance of U. longissima. Although most forest stand variables failed in this respect, there were indications of a certain negative influence of the historic logging activity. Number of thalli present on trees showed a unimodal relationship to present-day tree density, indicating that medium dense forest stands are most favorable for U. longissima. We tentatively suggest that selective logging, securing lichen-rich trees, may be a viable management option to keep tree density at a moderate level in the long run, thereby enhancing growth and establishment of U. longissima.

“…To select the appropriate level of harvesting intensity for a certain stand is a basic challenge in forest management planning. The decision depends on economic as well as biological factors [25]. Forest management employing clear-cut harvesting and artificial reforestation has been the dominant silviculture regime in natural forests in China for 50-60 years.…”

“…This increased interest is partly due to expected enhancements for landscape aesthetics and biodiversity, and to expected benefits for reforestation costs, timber quality, and profits. Selective harvesting has certain characteristics: (i) only a part of the standing volume is harvested; (ii) conditions for recruitment are favoured in order to maintain or develop an uneven-aged forest structure; (iii) the decision unit is the individual tree, or small groups of trees; and (iv) the choice of trees to be harvested is based on certain specified attributes (e.g., tree size, timber quality, volume increment, or financial maturity) [25]. Long-term field experiments with selective harvesting in uneven-aged coniferous forests have shown that inappropriate forest structures and poor conditions for natural reforestation can cause low volume production, and hence, low profitability [26].…”

“…It only considered economic benefits and seriously damaged the ecological environment. A large number of studies have shown that selective harvesting is the most suitable management of natural secondary forests [19,25,33]. But, for specific natural secondary forest, in order to protect species diversity and maintain community stability, the suitable selective harvesting intensity is not yet clear.…”

Abstract:The mixed Cunninghamia lanceolata (Lamb.) Hook., Pinus massoniana Lamb., and hardwood forest in southeastern China is a major assemblage in natural secondary forests, and of national and international importance in terms of both timber and ecosystem services. However, over-harvesting has threatened its long-term sustainability, and there is a knowledge gap relating to the effect of harvesting on the ecosystem. After conifer species were selected for harvesting, the mixed Chinese fir, pine, and hardwood forest was changed into mixed evergreen broadleaf forest. In this context, we observed the restoration dynamics of plant communities over a period of 15 years (1996 to 2011) with different levels of harvesting intensity, including selective harvesting at low (13.0% removal of growing stock volume), medium (29.1%), high (45.8%), and extra-high (67.1%) intensities, as well as clear-cut harvesting (100.0%), with non-harvesting as the control, based on permanent sample plots established in a randomized block design in these forests in southeastern China. The impact on the richness, diversity, and evenness of plant species derived from descriptive statistical analyses was shown to initially increase, and then decrease, with an increase in harvesting intensity. The most critical impacts were on the richness, diversity, and evenness of shrub and herb species. Richness, diversity, and evenness of plant species recovered and increased under selective harvesting at low and medium intensities, while these parameters had not recovered and significantly decreased under selective harvesting at high and extra-high intensities, as well as with clear-cut harvesting. The impact on the plant community stability was derived from the stability test method of the improved Godron M. The plant community stability was closest to the point of stability (20/80) under selective harvesting at medium intensity, followed by selective harvesting at low intensity. The plant community stability was far from the point of stability (20/80) under selective harvesting at high and extra-high intensities, as well as with clear-cut harvesting. Of these treatments, clear-cut harvesting had the greatest effect with regard to reducing stability. Therefore, these results indicate that the selective harvesting at low and medium intensities is conducive to preserve or increase the species diversity and community stability. In order to prioritize promoting plant species diversity, clear-cut harvesting and selective harvesting at high and extra-high intensities should be avoided with regard to this type of forest in this region. This study sheds light on the practice of forest operation in the study region and subtropical forests with the same environment.
