“…Our findings, therefore, support the studies of Dobrowolska (2007) and Khodaverdi et al (2019) but disagrees with Griffiths et al (2007). Several researchers have also stressed the role of gap disturbance on species diversity (e.g., Busing & White 1997;Dobrowolska 2007;Khodaverdi et al 2019) via the subsequent creation of favorable conditions at growing sites especially increasing light condition (Bullock 2000;Dusan et al 2007;Vilhar 2015) and explaining the mechanisms of species coexistence in gaps (Pacala & Levin1997;Wang et al 2017b).…”

“…Gap regeneration is a nature-promoting silviculture technique that champions the quest for sustainable natural forest management. Within the last 30 years, this concept has gained much research attention globally (e.g., Runkle 1990;Bullock 2000;Dusan et al 2007;Wang et al 2017b;Hammond & Pokorný 2020a) since its inception in the 20 th century (Watt 1947;Runkle 1981) due to its unmatched positive ecological importance on sustainability of mixed-species forests. The recent promotion of mixed stands in sustainable forest management is unquestionably owing to the importance of species diversity (Pretzsch 2009;Hammond et al 2020) in providing numerous forest functions and services (Del Río et al 2018).…”

Gap regeneration remains the best silviculture technique for sustainable forest regeneration in mixed forests. The study examined tree species composition, diversity and dynamics of natural regeneration in gaps under three contrasting forest stands at Křtiny in the Czech Republic. In spring 2013, experimental gap design begins, when semi-permanent 1 m2 circular sub-sampling plots along North-South-East-West transects were delineated under 6 selected natural canopy openings ≤ 20 m2. In winter 2013/14, these naturally originated openings were artificially enlarged to the current gap sizes ranging between 255 and 1149 m2 through group felling. Natural regeneration in gaps was measured four times: from the growing season before disturbance (BD) in 2013 to the next three consecutive growing seasons after disturbance in 2014 – 2016, respectively. Seven (7) new species with light demanding growth strategy that were previously not present at mother stands were occurring there during the first growing season after disturbance (FGS), yielding the highest taxa (14 species) and diversity (Shannon diversity index, H = 1.7) while BD attained the lowest (8 species; H = 0.9), respectively. Study site being part of Fagus sylvatica vegetation community and providing favorable natural conditions for the optimal growth of Picea abies significantly explains the regeneration dominance of these species in gap regeneration from BD until the third growing season after disturbance (TGS), respectively. Small scale gap-disturbance contributed to the higher regeneration densities of all studied species during FGS. However, drought, competition from other life forms, and browsing activities substantially caused a progressive decline in natural regeneration during three consecutive years after disturbance.

“…Cultivating plantations is an effective way to preserve and protect natural forest resources. Artificially reconstructed forests play a critical role in improving the environment, promoting industrial restructuring, and alleviating timber supply pressure (Aronson & Alexander 2013, Wang et al 2017. The rise of the 20 th century brought rapid development in the industrial world; thus, the race of vast accumulation of wealth negatively impacted the world's forests, and forest areas sharply decreased in many countries/regions (Trumbore et al 2015).…”

Biogeosciences and Forestry Biogeosciences and Forestry Perspectives of plantation forests in the sustainable forest development of ChinaTaimoor Hassan Farooq (1-2) , Awais Shakoor (3) , Xiaohong Wu (1-2) , Yong Li (1-2) , Muhammad Haroon U Rashid (4) , Xiang Zhang (1-2) , Matoor Mohsin Gilani (4) , Uttam Kumar (5) , Xiaoyong Chen (2-6) , Wende Yan (1-2) Modern forestry is gradually moving towards man-made forests on a large scale. Plantations with advanced forestry system have been introduced with the goal of sustainable forestry development and to enhance social, ecological, and economic benefits. Forest plantations with native and exotic species have been established in China and worldwide with shorter rotation cycles than natural forests. In this paper, we discuss the role and perspectives of plantation forests in the Chinese sustainable forest development, the evolution of various plantation programs, the ecological effects of plantations, and the measures to improve plantation forestry. The Chinese government has given substantial importance to nurturing plantation forest resources through various large scale afforestation programs. In 2019, the total area covered by plantations in China reached 79.54 million ha, with a stock volume of 3.39 billion m³ (59.30 m³ per ha); coniferous forests (26.11 million ha, 32.83%) and broad-leaved forests (26.45 million ha, 33.25%) are the dominant types. Plantations have been primarily distributed in the central and southern parts of the country. Plantations with fast-growing and high-yielding tree species facilitated Chinese afforestation activities and improved the administration of forest production, which effectively boosted the forest industry. Plantation forest resources offer many potential productive, economic, and social advantages, though they are also associated with a loss of biodiversity and climate change makes them likely susceptible to disease and insect attack. Appropriate forest management practices during planning, execution, and maintenance of plantations can contribute to the conservation, promotion, and restoration of biodiversity, with the final aim of attaining a balance between having forest plantations and natural forests.

“…Some previous works theorized that microbial communities are correlated with their function, and microbial community structure and function strongly influence soil carbon dynamics [14][15][16]. Soil microorganisms depolymerized soil organic matter by producing extracellular enzymes, which are involved in soil nutrient cycling [17].…”

Microbial communities and their associated enzyme activities play key roles in carbon cycling in ecosystems. Forest thinning is likely to change the soil properties and feedbacks on the structure and function of microbial communities, consequently affecting microbial regulation on the soil carbon process. However, few studies have focused on the mechanism of how thinning affects the quantity and stability of soil carbon. To reveal the influence of thinning on soil carbon and to explore the regulated key factors, this study was conducted in a pure Larix principis-rupprechtii Mayr plantation with different thinning intensity (light, medium, and high) in Shanxi province, China. Soil properties (soil pH, soil water content, soil organic carbon, and soil microbial biomass carbon) were measured. Meanwhile, soil microbial communities were examined with the method of phospholipid fatty acid (PLFA), and soil enzyme activities were measured as indicators of soil microbial functions. The results showed that medium and high thinning has positive effects on soil organic carbon, microbial biomass carbon, soil microbial abundance, and soil enzyme activities. Actinomycetes and gram-negative bacteria were the major factors to affect soil microbial community function relating to carbon decomposition. Soil pH contributed to actinomycetes and gram-negative bacteria through direct influences on arbuscular mycorrhizal fungi. Moreover, there were strong correlations between soil pH and microbial community to control soil carbon turnover. The increasing of soil microbial abundance and the microbial regulation on soil carbon in forest thinning need to be considered for sustainable forest management practices in northern China.
