The forest litter in mountain forest stands plays an important role in terms of its ability to mitigate the impact of tourist activities, and erosion processes along with its contribution to the soil mineralization. Water interception, infiltration, and retention ability of forest litter have an impact on hydrological processes of forest ecosystems. At the same time, the accumulation and spatial distribution of litter can be affected not only by environmental conditions, but also by tourism. In this study, 13 Norway spruce (Picea abies L.) stands distinguished by average distance to the trail were chosen to investigate whether there are any differences in litter structure, water retention, and infiltration abilities as well as litter accumulation in areas along popular hiking trails in the Ukrainian Carpathians. Results showed that the litter thickness has increased with altitude and slope steepness. Moreover, results of one-way ANOVA demonstrate a significant difference (P < 0.05) in litter stock between two groups of sample plots: established directly to adjoin hiking trails and at a distance. Therefore, the forest litter stock nearby hiking trails may indicate that trampling caused by tourists has a negative impact on litter accumulation. However, no statistical difference was found (P > 0.05) in the accumulation of litter along three trails and altitudes across all surveyed forest stands. Results of the immersion test showed that the litter infiltration rate has a significant negative correlation with the maximum mass of absorbed water (r = -0.62, P < 0.05), litter stock (r = -0.69, P < 0.01), and retained precipitation (r = -0.62, P < 0.05). Despite our assumption, the infiltration rate was lower for sites distanced from the hiking trail in comparison with adjoining ones. According to our measurements, the water holding capacity of the litter varies from 42.3 t.ha-1 to 187.3 t.ha-1 regardless of the stand composition. Further, the precipitation amount retained by litter varies between 4.2 mm and 18.7 mm. Insignificant differences in litter fractional structure and accumulation were observed in pure spruce stands and mixed spruce-beech with an admixture of beech up to 20%. Further observational and modelling studies are necessary to clarify the role of the beech share in stand composition in relation to fractional structure and water interception and retention ability.

Accessible and effective eco-friendly insecticides are required for the pest control. Thus, susceptibility of 2nd and 4th instar larvae of BTM to commercial formulation of Bacillus thuringiensis (Bt), two plant extract formulations, Bio1® and Matrine®, and three insect growth regulator (IGR) insecticides, chlorfluazuron, chromafenozide and diflubenzuron were investigated in laboratory bioassay. Except for diflubenzuron, significant mortality of both instar larvae was observed. At the endpoint of the experiments (96 h), 75.2-90% of second and 80-85% of fourth instar larvae had already died, as a result of feeding on leaves treated with the highest concentration of the insecticides. Furthermore, based on Probit analysis, Matrine® exhibited the highest efficiency (lethal concentration LC50 = 2.87 μL.L-1) on 2nd instar larvae and followed by Bio1® (8.07 μL.L-1), chlorfluazuron (173.3 μL.L-1) and Bt (326.3 mg.L-1). The LC50 of Matrine® and Bt for 4th instar larvae were 1.75 μL.L-1 and 335.8 mg.L-1, respectively. Our study revealed that Matrine® and chromafenozide could be alternatively used against BTM in situations where there is a permission and need to use insecticides.

Babol Roud forestry plan is located in Lafoor forest area in the Babol County, the Mazandaran Province, Northeast Iran. This research was divided into three steps: first of all, by making use of Cochran's formula, we identified the number of participants. Later on, the Delphi method was employed in order to determine criteria and subcriteria through the questionnaires. From then on, Fuzzy Analytic Hierarchy Process (FAHP) was used to quantify the criteria that were weighted by experts' viewpoints through the planned questionnaires. By adopting the Fuzzy Forests method, we found out that the economic, environmental, social and managerial criteria are most prominent. Forestry project staff's income was in the highest relative weight (0.23) based on participant's viewpoint. Most of the participants in the study did not give their consent to the forestry plan suspension due to the inevitably forthcoming economic and environmental problems ahead. Instead, they strongly underlined the need to go into immediate action such as revising the former plans as well as constant stream of close attention to the plan execution details of the ongoing process. Eventually, developing a new policy and using alternative forest management strategies that would meet the needs of all various stakeholders have been recommended.

The stool value was assessed by evaluating the morphological features. Stools were selected in forest stands with an age of 80 years and older. We analysed the potential influence of twenty-five variables (for example, the exposure, forest vegetation zone, potential natural vegetation, actual or historical owner, edaphic category, etc.) on the stool value. We found that the historical ownership, climatic region, and category of potential natural vegetation significantly affect the coppice stool value. We observed the occurrence of stools with a higher stool value in moderate climatic region type 3 (MT3), in scree and ravine woodlands and in the territory of the historical owners of the Mitrovsky and Salm-Reifferscheid families. According to our results, the probability of the occurrence of coppice stools decreases with an increasing stool value.
