“…Therefore, plant species diversity is one of the most important variables in evaluating the management of forest areas (Baran et al 2018;Miller et al 2019). The amount of plant species diversity in the forest is influenced by the location of the forest areas in terms of elevation, aspect, slope, rainfall, average temperature and fertility (Mahmodi et al 2019;Muys et al 2022;Tynsong et al 2022), the type of vegetation (Lelli et al 2019), the evolutionary stages of natural stands (Mohammadnezhad-Kiasari et al 2018), the type of management (Kazemi et al 2015;Wulandari et al 2018), the history of forest exploitation (Nasiri et al 2022) and the influence of canopy gaps size (Hamrang et al 2014). Numerous studies have shown that the protection of forest areas increases the biodiversity of plant species compared to abandoned forests (Miller et al 2019;Muys et al 2022;Opuni-Frimpong et al 2021;Rezaipoor et al 2022).…”

“…Hyrcanian forests in Iran are approximately 800 km long and 110 km wide with a total area of 1.85 million ha, or equivalent to 15% of the total Iranian forests and 1.1% of the country area (Sagheb-Talebi 2017). These forests in northern Iran have important tree and shrub elements of Euro-Siberian; among them, oriental beech (Fagus orientalis Lipsky) is one of the most important industrial species and widely covers from the Western to the Eastern Hyrcanian region (Espahbodi et al 2021;Nasiri et al 2022). Oriental beech is native to Eurasia, from Eastern Europe to Western Asia, and the implementation of appropriate management in beech forests is highly important due to economic and ecological values (Sagheb-Talebi et al 2014;Francesco et al 2023).…”

“…The results of numerous researches on the effect of shelterwood cutting system on stand structure and regeneration abundance have confirmed that instead of shelterwood cutting system, other silvicultural practices such as the single-tree selection cutting should be applied for the mountainous beech stands of Hyrcanian forests. The selection silvicultural system is a system of tree harvesting in which one (tree-selection) or a few (group-selection) numbers of trees are being cut at each intervention (Pourmajidian et al 2010;Sagheb-Talebi et al 2014;Habashi and Waez-Mousavi 2018;Nasiri et al 2022). In the context of this study, forest management is referred to the single-tree selection cutting.…”

Abstract. Kiasari MSh, Sagheb-Talebi Kh, Rahmani R, Ghelichnia H. 2023. Comparison of plant diversity between managed and unmanaged forests in Haftkhal, Mazandaran Province, North of Iran. Asian J For 7: 106-113. The relationship of plant diversity with silvicultural practices has not been fully understood for the oriental beech forests (Fagus orientalis Lipsky), which is a widespread forest tree in the Hyrcanian Region, Iran. The implementation of appropriate forestry practices in the oriental beech forests is therefore crucial in terms of sustainable forest management. Hence, assessing the impacts of silvicultural practices on plant diversity is essential with the regard to sustainable forest management. This study aimed to compare plant species diversity between two managed and unmanaged forest stands in Mazandaran Province, Iran. Forest inventory in an area of 131 ha was performed using in a systematic random sampling with a 150 × 200 m grid size. In addition, the area of sampling was 100 m2 (10 × 10 m). Twenty and thirty sampling plots were established in managed (compartment No. 8) and unmanaged (compartment No. 36) forests, respectively. Shannon-Wiener and Simpson Indices were used to calculate plant species diversity, while Margalef and Sheldon indices were used to determine species richness and evenness, respectively. The results revealed that 50 and 56 plant species were found in managed and unmanaged forests, respectively. Rosaceae, Asteraceae, and Fabaceae were the main families in these studied areas. This study showed that the diversity and richness of plants in the managed forest slightly increased compared to the unmanaged forest. On the other hand, the evenness of plants in the managed forest slightly decreased compared to the unmanaged forest. Changes in plant diversity indices between managed and unmanaged forests were not statistically significant. This research showed that forest management of oriental beech forests using the single-tree selection cutting has not reduced or weakened the diversity of plant species in the managed forest compared to the unmanaged forest.

Firewood extraction by mule forwarding is still common in oak coppices in Central and Southern Italy. This is due to the scarce presence of aerial extraction systems such as cable yarders. Considering the importance of forest soil for all ecosystem services, the evaluation of the disturbance that a given extraction system has on the forest soil is a fundamental aspect in the framework of sustainable forest management. Therefore, this study was developed to assess the disturbance caused to the physicochemical and biological features of soil and to coppice after mule logging according to the standards of silvicultural treatment, as well as the recovery time needed after the logging intervention. Four cutting blocks located in Central Italy represented the study area, one cutting block represented the unharvested control, while the others were logged 3 years (CB-2019), 8 years (CB-2014) and 10 years (CB-2012) prior to the field surveys. In each harvested cutting block the soil was subdivided into disturbed soil (DIST—mule trails) and low disturbance soil (LD—area within the harvested cutting block not affected by mule passage). This experimental design assessed the disturbance caused by logging operations by mules (DIST soil) and the silvicultural treatment (LD soil) to soil physicochemical (bulk density, penetration resistance, shear resistance, and soil organic matter) and biological properties (soil microarthropod community evaluated with the QBS-ar index). The results revealed a significant disturbance in the mule trails for all the investigated variables. The disturbance was particularly strong for the QBS-ar index, with values which were lower than half of those of the control area. Furthermore, no recovery process was evident even after 10 years from the logging interventions. Instead, values of the various parameters became worse with time after harvesting. On the other hand, no marked disturbance was revealed in LD soil, except for a significant decrease in soil organic matter. Although this is a preliminary evaluation that needs to be confirmed with further study, this trial suggested that mule logging cannot be considered a fully low-impact approach to forest operations and that studies with a longer time span after harvesting are needed to assess the recovery process in the mule trails.
