Analysis of forest areas in forest parks of Ekaterinburg was carried out based on GIS database of AWP Lesfond program. A database of distribution of undergrowth species in forest parks was formed and then analyzed with Microsoft Excel. Regularities in the distribution of local and introductory undergrowth species in pine forests of Ekaterinburg were determined. The area of pine forests having undergrowth of twelve aboriginal, two invasive species and ten species in artificial plantings in six forest parks of Ekaterinburg - Kalinovsky, Moskovsky, Yuzhny, Nizhneisetsky, Shuvakishsky and im. Lesovodov Rossii - was determined. Analysis of the data showed that the area covered with prickly wild rose ( Rosa acicularis ) constituted 811.4 hectares of all the undergrowth territory (9848.45 hectares), but its distribution in forest park was extremely heterogeneous. Rosa acicularis occurs in the Nizhneisetskiy forest park more often than in other forest parks (273.1 ha). This species is common in nine types of forest, its ecological and phytocenotic distribution optimum is berry pine forest with 0.6-0.9 stand of trees. Presence of prickly wild rose in undergrowth and condition of its cenopopulations indicate a typical composition of plants in the forest park zone of Ekaterinburg. In the forest parks studied, Rosa acicularis is one of the co-edificators in indigenous forest types, along with Sorbus aucuparia , Rubus idaeus , Prunus padus , Salix caprea , Chamaecytisus ruthenicus , Rosa acicularis . The data given on the calculation of forest areas with prickly wild rose are the basis for inventory of valuable medicinal raw materials and ready-made decorative forms for the introduction of urban landscaping.

The Impact

The parameters of the undergrowth in the forbs and berry groups of pine forest types in 9 parks in Yekaterinburg and areas of natural forest have been investigated. Data on the species composition, density, and distribution by groups of heights of plants that make up the undergrowth collected. It has been established that the transformation of the undergrowth by an urbanized environment neutralizes the influence of the growing conditions of the considered forest types on it. In the forest-park zone, an increase in the density of the undergrowth is observed in comparison with the natural forest. The specificity of the forest park undergrowth is the floristic contamination with adventive species, the number of which is close to 50% of the total number of undergrowth species. The coefficient of floristic similarity of the undergrowth, according to the Sorensen coefficient between forest parks and a site of natural forest, was 0.26-0.46. In quantitative terms, the self-seeding of adventive species in the undergrowth is less than that of native plants. The invasive activity of ash-leaved maple in city parks and its dynamics over a 10-year period are considered, using the example of one of the parks.

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 forest site capacity using was quantitatively assessed for the stands of the main forest-forming species of Ukraine, Scots pine and common oak, taking into account natural zones and forest types. The tables of productivity of modal and highly productive pine and oak stands have been developed. It has been found that the stands use an average of 50–75 % of the forest site capacity of lands. The average weighted value of the capacity used by pine forests was 68–76 % in the Polissya zone, 70–78 % and 68–73 % in the Right-bank and Left-bank Forest-Steppe zones respectively, and 54–78 % in the Steppe zone. For oak stands, the value was 71–75 % and 63–71 % for the Right-bank and Left-bank Forest-Steppe zones respectively and 65–75 % for the Steppe zone. The basis for increasing the productivity of forests was confirmed to be the differentiation of forest management systems and individual forestry activities on a zonal and typological basis.

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.

Shrimp Shell Waste

Feed is still one of the problems in aquaculture because it takes about 70% of operational costs. High prices is caused by imported raw materials for feed production. One possible effort to overcome this problem is to find alternative local raw materials to replace imported fish meal. The purpose of this study was to examine the proximate content of shrimp shell wastes from processing shrimp crackers (Paneus sp.) to be used as shrimp flour. Samples were colledted three times in a month, at the beginning, middle and end of the month. The waste of the heads, shells and tails of the shrimp were turned into flour for laboratory testing through proximate analysis. The data were tabulated using the Microsoft Excel softwareand then analyzed descriptively by comparing the nutrient content of shrimp waste flour with the feed requirements of mariculture. The results showed that shrimp shell flour contained protein, fat, carbohydrates and ash content of around 27.4%, 2.07%, 14.84% and 47.27%. while the resulting randemen ranged from 81.75%. Therefore, shrimp shell flour can be used as an alternative raw material for preparing marine fish feed.

Facial Images

Urban forests can attract visitors by the function of well-being improvement, which can be evaluated by analyzing the big-data from the social networking services (SNS). In this study, 935 facial images of visitors to nine urban forest parks were screened and downloaded from check-in records in the SNS platform of Sina Micro-Blog at cities of Changchun, Harbin, and Shenyang in Northeast China. Images were recognized for facial expressions by FaceReaderTM to read out eight emotional expressions: neutral, happy, sad, angry, surprised, scared, disgusted, and contempt. The number of images by women was larger than that by men. Compared to images from Changchun, those from Shenyang harbored higher neutral degree, which showed a positive relationship with the distance of forest park from downtown. In Changchun, the angry, surprised, and disgusted degrees decreased with the increase of distance of forest park from downtown, while the happy and disgusted degrees showed the same trend in Shenyang. In forest parks at city center and remote-rural areas, the neutral degree was positively correlated with the angry, surprised and contempt degrees but negatively correlated with the happy and disgusted degrees. In the sub-urban area the correlation of neutral with both surprised and disgusted degrees disappeared. Our study can be referred to by urban planning to evaluate the perceived well-being in urban forests through analyzing facial expressions of images from SNS.

The aim of the work is to establish how greatly the light conditions change under the leaf canopy of two invasive plant species in the Middle Urals - Acer negundo and Sorbaria sorbifolia . In June - August 2020, using a portable light meter, 8370 measurements of illumination were performed in forest parks (at a height of 1.5 and 0.5 m, i.e. above and below the canopy of the leaves of the invasive shrub S. sorbifolia and the native shrub Rubus idaeus ; in random points under the canopies of Pinus sylvestris ; on glades, paths and forest edges) and in urban habitats (at a height of 1.5 m and 0.5 m in dense thickets of the invasive tree A. negundo and other tree species). The average illumination intensity was as following: under S. sorbifolia - 4 ± 1 lux × 10; under R. idaeus - 7 ± 1 lux × 10; in A. negundo thickets - 13 ± 2 lux × 10; in thickets of other tree species - 25 ± 4 lux × 10; under the canopies of urban pine forests - 80 ± 10 lux × 10; in the forest edges - 96 ± 14 lux × 10. In dense thickets, A. negundo intercepts about 94% of the light falling on its canopies, S. sorbifolia - about 93%. This is significantly higher than the light interception level in habitats used as control: other tree species canopies of greatly urbanized habitats intercept about 89%, the thickets of R. idaeus - about 82%. Thus, invasive plants reduce the amount of light available to other plant species in communities significantly more than native plants.
