“…The results are consistent with previous reports, such as Endris et al (2017); Kacholi (2014) that increasing tree size classes results in a drastically decreased number of species and Shannon diversity index. Basal area and AGC were increased from smaller to bigger size classes in the BP and MP forests (Goode et al 2020). The SP forest also had the lowest AGC compared to the other 2 sites, especially in the biggest dbh class (Figure 2D-E).…”

Abstract. Wannasingha W, Gomontean B, Uttaruk Y. 2023. Forest structures and carbon stocks of community forests with different forest management in Maha Sarakham Province, Thailand. Biodiversitas 24: 799-809. Forest management comprises strategies and practices to regulate human activities and the utilization of forest products. Management and regulations have various effects on forest structure, tree diversity and carbon accumulation. This study was conducted in three community forests with different levels of rule regulations and managed duration in the northeast of Thailand. Thirty of 20×20 m plots were placed for recording all trees with diameter at breast height (dbh) ?4.5 cm and >1.3 m height. One hundred and fifty plots of soil samples at 0-25 cm and 25-50 cm depths were also collected for organic carbon analysis. Forest carbon stocks were calculated from the sum of carbon in aboveground biomass (AGB) and soil organic carbon (SOC). The results showed that tree density, basal area, Shannon diversity index and evenness index of the best practices (BP) plots were higher than the plots in which moderate (MP) and slight practices (SP) were applied. Tree heights of the BP and MP forests were higher than the SP forest. The L-shape of dbh class distribution in all community forests means they were secondary forests; tree density was highest in the small dbh class and declined in the bigger size class. The bigger dbh class tree showed higher aboveground carbon (AGC) despite the lower tree density in all community forests. Most of the BP forest plots had the highest carbon stock (93.89, 80.52 and 54.96 Mg C ha-1) and CO2 absorption (344.25, 295.23 and 201.53 Mg CO2equiv.) compared with the others. Our results demonstrate the importance of forest management in affecting forest structures, carbon sequestration and carbon dioxide absorption from the atmosphere to reduce and mitigate climate change.

“…vegetation density, height and vertical variation in cover), standardised metrics allow for straightforward comparison of the structure of plant communities between habitats and over time (McElhinny et al, 2005). In the context of forestry management, such comparisons can elucidate the effects of different forestry practices on stand structure (Castro‐Izaguirre et al, 2016; Chamberlain et al, 2021; Deere et al, 2020; Goode et al, 2020; Juchheim et al, 2020; Munro et al, 2009; Parrotta et al, 1997; Põldveer et al, 2021) and above‐ground primary production (Dănescu et al, 2016; Hardiman et al, 2011; Ishii et al, 2004; LaRue et al, 2018; Mensah et al, 2020). Variation in vegetation structure—whether driven by human activity or arising naturally across biotic and abiotic gradients—has also been linked to variation in a number of important ecological functions, including cascading effects on faunal diversity (Iezzi et al, 2018; Ishii et al, 2004; Morante‐Filho et al, 2018; Sukma et al, 2019), microclimate regulation (Ehbrecht et al, 2017; Guimarães‐Steinicke et al, 2021; Rissanen et al, 2019) and species interactions (Kostenko et al, 2015; Langellotto & Denno, 2004; McDonnell & Stiles, 1983; Warfe & Barmuta, 2004).…”

Vegetation structural complexity (VSC)—the three‐dimensional distribution of plants within an ecosystem—is an important ecological trait. To date, research has focused primarily on the effects of VSC on ecological patterns and processes, but comparatively little is known about what drives variation in VSC. Recent advances in active remote sensing technology, particularly light detection and ranging and radio detection and ranging, have allowed the measurement of VSC at unprecedented spatial scales and resolutions. Out of this and earlier work has emerged evidence that VSC is typically associated with greater ecosystem functioning (especially microclimate regulation, productivity, faunal diversity and habitat provisioning), making restoration of vegetation complexity a potentially powerful restoration tool. Recent studies of VSC across natural and experimental gradients of plant diversity have also revealed that more diverse plant communities tend to be more structurally complex. However, the shape and generality of this relationship—and the mechanism(s) by which phytodiversity might contribute to structural complexity—remain poorly understood. Here, we review how active remote sensing has facilitated recent VSC research and shaped our understanding of the relationship between vegetation complexity and ecosystem function. We then present a theoretical framework for the relationship between phytodiversity and VSC based on classic biodiversity‐ecosystem functioning principles. Finally, we evaluate the evidence for the notion that diverse plant assemblages tend to be more structurally complex and explore the shape of the relationship between phytodiversity and VSC using data from 13 recent remote sensing studies. Synthesis. The relationship between phytodiversity and VSC appears to be almost universally positive. Preliminary evidence further suggests that the most common relationships between phytodiversity and VSC are linear or saturating, indicating that the extent of functional redundancy between species varies across plant communities and ecosystems. In contrast, we find little evidence for exponential or negative relationships between plant diversity and VSC, suggesting that even modest increases in plant diversity could markedly increase structural complexity. Additional investigations of phytodiversity‐VSC relationships are necessary to establish whether the observed positive relationships are causal (and, if so, in which direction) and to clarify the potential impact of plant community restoration on structural complexity and broader ecosystem function.
