The research conducted was to assess the characteristics of intraspecific and interspecific interaction of the dominant tree species in the forest-park plantations of Vinnytsia green zone, as well as to determine the priority taxation indicators of formation of forest stands with high competitive ability.As a result of the research it was found that the main indicators that directly affect the competitive properties of forest elements are the sanitary condition of forest plantations; the composition of the stand and its storey structure; the undergrowth and underwood availability; biological and ecological features of individual tree species; stand completeness; age of planting; type of forest vegetation conditions; specific features of microclimate and microrelief. The analysis of the sanitary condition of the trial areas shows that the degree of competitive ability of forest plantations with a high number of dead or damaged trees is much lower than that in plantations with better sanitary conditions. The dependence of the competitive ability and the stand growth intensity on its completeness and the type of forest-park landscape was also studied. Thus, closed types of stands are characterized by a high degree of competitiveness. In semi-open types of forest-park landscapes the rate of growth intensity is the highest. The competitive ability of trees in this type of landscape is quite low. After analyzing the temperature regime of different forest parks, it was found that in hot weather the ambient temperature in the forest park is much lower than the air temperature in the open area. Thus, in hot uncomfortable weather, the optimal type of forest for recreation is a closed type of landscape of vertical closure. The air temperature here can be significantly lower (up to 15˚C) compared to the open space, what creates suitable conditions for a comfortable rest. Analysis of the humidity of forest parks showed that under the cover of forest stands humidity is higher than in the open area, thus recommendations for choosing the type of forest landscape for recreation purposes depend on the initial humidity. Key words: recreation, forest parks, intraspecific interaction, forest park landscape, winter hardiness, temperature regime, light intensity, air humidity.

Reclamation of land on community land funds and the hydrographic network contributes to the most effective means of protecting the soil from water erosion. However, the condition, growth, and productivity of the protective forest stands themselves depend on the species composition. Many years of studies have clearly shown that not all tree species and shrubs can successfully grow on washed soils. Extensive scientific material provides a description of the growth and current status of the studied species, a detailed taxation description of the forest plantations. Of particular value are those species that can grow on eroded lands and protect the soil from erosion.

Forest Parks

Forest parks can take a role in mitigating negative impact of Urban Heat Island. Therefore, this study was conducted to clarify ecological function of three forest parks i.e Ganesha, Maluku, and Tegalega forest park in mitigating Urban Heat Island. Land classification and surface temperature were determined by analyzing Landsat 8 image with QGIS. Air temperature was measured by mobile station through north-south and east-west of Bandung City area. There are four types of land classification in Bandung as follows: settlements, water body, bare soil, and vegetation. In Bandung City, vegetation cover is around 20.72%; surface temperatures in the afternoon varies from 23 to 39.6°C, while during the night air temperatures varies from 20.5 to 24.9°C. Northern part of Bandung tends to have cooler air temperature due to high coverage of vegetation. Tegalega forest park can reduce temperature up to 2.6°C, while in Maluku forest park is 1.98°C and Ganesha forest park is 0.75°C. Therefore, the existence of forest parks is important in urban area because they can take a part to reduce negative impact of Urban Heat Island.

Forest stands of the arboretum contribute to the preservation of ecological balance on the territory of Barnaul. It contains a large number of tree species, one of which is poplar birch (Betulapopulifolia). The article shows that over the years of research, the water regime in the Chernozem profile under birch stands remains tense for most of the growing season, so there is a need to use irrigation with different irrigation standards, depending on the emerging hydrological state.

Urban parks positively affect the life quality and health of urban residents as well as the environment where they live. When it comes to the design of a future urban forest park, it is necessary to consider the protection of ecological environment, landscape sustainability and practicability. This study explored residents’ spatial preference for urban forest parks based on preference survey data. According to the rating scores obtained for four urban forest park routes during physical activities, this study used cognitive maps and multinomial logit models to figure out the potential influencing factors affecting residents’ spatial preference while they engage in physical activities. The results suggest that forest routes are still the primary choice for urban residents. Although familiarity with the spatial image preference for urban forest parks varied from person to person, residents’ choice of route shows certain commonalities, which was reflected in the sequential cognitive maps obtained from them. In addition, residents’ route preference is influenced by their exercise habits, environmental preference and residential location. There is also a certain correlation between residents’ preference and their characteristics. This study provides additional information for planners, developers, engineers, architects and foresters in building a more suitable environment that is aesthetically appealing and ecologically sound for physical exercising.

A growing number of studies suggest that the perceived sensory dimensions (PSDs) of green space are associated with stress restoration offered by restorative environment. However, there is little known about PSDs and stress restoration as well as their relationship to forest park. To fill this gap, an on-site questionnaire survey was conducted in three forest parks in Beijing, as a result of which a total number of 432 completed responses were collected and analyzed. The mean values of PSDs were used to represent PSDs of forest park. Using independent sample t-test and ANOVA, this study analyzed the individual characteristics that affected PSDs and stress restoration. Linear mixed model was used to identify the relationship between PSDs and stress restoration of forest park, which took into account the interactions of stress level and PSDs. The results showed that: (1) the perceived degree of PSDs in forest park from strong to weak was Serene, Space, Nature, Rich in species, Prospect, Refuge, Social and Culture, which varied with visitors’ gender, age, level of stress, visit frequency, activity intensity, visit duration and commuting time; (2) in PSDs, Refuge, Serene, Social and Prospect had significantly positive effects on the stress restoration of forest parks (3) there was no significant difference in the effect of the eight PSDs on the stress restoration between different stress groups; (4) stress restoration was influenced by visitors’ gender, age, visit frequency and visit duration. These findings can offer references for managers to improve the health benefits of forest park for visitors, and can enrich the knowledge about PSDs and stress restoration.

The potential of Urban Forest Park and publics' views are clearly pertinent in urban greening and sustainability, yet they are often ignored by certain countries. In line with this, the Town and Country Planning Department and National Landscape Department had taken steps by developing more urban parks and urban forest parks to enhance the quality and sustainability in urban environment. The study was conducted at FRIM(Forest Research Institution of Malaysia) with 375 respondents participated in this study. It is found that the respondents' evaluation on environmental, social and physical contribution at study area is associated with great and intense values for city sustainability. Public opinion and reason to come to the study area should be taken into account by professionals since they are the users and responsible to ensure thesustainability of urban forest for future generation. Even though the overall percentage of survey showed that public gave good expectation, however, the small percentage could be an eye opener as they assumed the existing setting will face big challenge to sustain in the future.

As a result of nature resources intensive use, most of ecosystems have beenconverted. Anthropogenic impact includes changes of forest stands structure andtheir spatial specificity in the forest area. Accordingly the sanitary state of Norwayspruce young forest stands can be affected by different risk impact factors ofmanagement. The aim of the research was to analyze the spruce Picea abies (L. )Karst. young forest stands sanitary condition depending on forest plots spatialspecificity and location in the forest areas. The data were collected in 4 regions ofLatvia in spruce young forest stands (1 - 40 years old). The research was conductedin young natural and artificial stands (pure – 44, mixed – 42). In total 502 sampleplots with a total area of 28250 mwere installed. The particular plot size (25, 50,100 and 200 m) were selected depending on the stand average tree height, whiletheir number depended on the forest stand area. A total area of investigated foreststands were 127. 5 hectares. Results showed that the expression of spatial specificsdepended on risk factors and their intensity, as well as the environmentalcharacteristics. Damages caused by abiotic risk factors at different forest standswere not the same regarding intensity, nature and volume, but more or less closelywere related to all site conditions. Spatial specificity of forest stands area (regularand irregular), as well as their location in the forest massif significantly affects thespruce young forests sanitary status (respectively p=0. 027 and p=0. 002). Differentrisk factors damage to forests, bordering with spruce or pine young growths,cutovers and various types of infrastructure, were identified as much moreimportant.
