Knowledge about urban forests in Poland is still limited, as it is primarily based on aggregate, formal data relating to the general area, ignoring the spatial dimension and informal green areas. This article describes and analyses spatio-temporal changes in the actual urban forest resources in Wrocław in 1944–2017, which covers the first period of the city’s rebuilding after its destruction during World War II and its development during the nationalised, centrally-planned socialist economy, as well as the second period of intensive and only partly controlled growth under conditions of market economy. The study is based on current and historical orthophotomaps, which were confronted with cartographic data, as well as planning documents. We found that between 1944 and 2017, the percentage contribution of informal woodlands increased tenfold (from 0.5 to 4.9% of the present total area of the city). The area occupied by such forests has grown particularly during the most recent years of the city’s intensive development. However, the forests have been increasingly fragmented. During the first period, new forest areas were also created in the immediate vicinity of the city centre, while during the second one, only in its peripheral sections. The post-war plans regarding the urban green spaces (UGS), including the current plan, are very conservative in nature. On the one hand, this means no interference with the oldest, biggest, and most valuable forest complexes, but on the other hand, insufficient consideration of the intensive built-up area expansion on former agriculture areas. Only to a limited extent did the above-mentioned plans take into account the informal woodlands, which provide an opportunity for strengthening the functional connectivity of landscape.

Taman Hutan Kota PLN Medan is one of important part from the city, if the park managed properly it would give a good impact to increase the quality of public space which is lead to make a positive and better contribution to people's lives who lived in the busy city like Medan. However, in reality, Taman Hutan Kota PLN cannot make a good performance as its function as public space and urban forest. To increase the level of people's happiness and develop urban quality at Medan, it is necessary to redesign Taman Hutan Kota PLN. The redesign’s purpose is to fulfill the people’s needs and hopes to this park and make better, satisfying, and responsive facilities to the user.  Redesigning Taman Hutan Kota PLN will be based on people's preferences, perceptions, and perspectives. The preference, people's opinions, and documentation on the field will help us to discover what is the real reality and important resource for redesigning process so that the final result of the new Taman Hutan Kota PLN design can be a better park not only as public space and open green space but also as an alternative recreation facility for people in Medan.

Poaching is one of the greatest immediate threats and a serious conservation challenge facing wildlife in Borneo. Medium- to large-sized mammals, while charismatic, are hunted for consumption and sale. This study focuses on wildlife hunting and utilization of selected communities in a remote area in Sarawak, conducted using interview surveys within communities who hunt wildlife in Ulu Baleh. The calculated hunting pressure index in Ulu Baleh (2.24) is considered low compared to other parts of Sarawak. Local communities are dependent on wildlife protein and medicine. Even though the common hunting offtake included the bearded pig and deer species, for the hunter’s own consumption, hunters were opportunistic in taking non-target species and selling surplus meat. Lack of awareness of the implications of unsustainable hunting and difficulty in monitoring by the relevant authorities appear to be the main challenges to wildlife conservation in the area. This paper highlights the lack of research documenting wildlife utilization in the Ulu Baleh region and the implication of these results are particularly important for future adaptive wildlife management, especially for species of conservation importance in Sarawak.

There are 11 plant species of the Orchidaceae family in the city area of Tyumen; eight of them are protected in the Tyumen region, one species is included in the Red Book of Russia. Representatives of the family are found in the urban forest complex, roadside forest belts, on lawns and in public gardens of the central part of the city. Most species are represented locally by single specimens or small groups; three species – Epipactis helleborine, Platanthera bifolia and Neottianthe cucullata can form large complete coenopopulations. The main anthropogenous factors negatively affecting the condition of orchids in the city are: reconstruction of roads and plantations, regular mowing of grass in the habitats of plants. The protection of species requires coordinated efforts of municipal services for the improvement of urban areas and environmental organizations.

Abstract Background: The recent urban challenges due to climate change and urban environment deterioration requires proper planning and inventories of urban forests. In this paper, trees and shrub information were used to estimate leaf area/biomass, carbon storage, carbon sequestration, pollution removal, and volatile organic compound (VOC) emissions, hydrological and functional values of Adama city urban forest. This study was conducted to assess and quantify the ecosystem services of urban forests of Adama city, Central Ethiopia.Results: The result of i-tree Eco model has indicated that the tree species such as Azadirachta indica, Eucalyptus globulus, Carica papaya and Delonix regia sequester high percentage of carbon which is approximately 14.7%, 7.4%, 7.3% and 6.2% of all annually sequestered carbon respectively. Besides, urban forests of the city was estimated to store 116,000 tons of carbon; the most carbons were stored by the species such as Eucalyptus globulus, Azadirachta indica, Carica papaya and Delonix regia that stores approximately 22.1%, 12.3%, 9.5% and 4.2% of all stored carbon respectively. Trees in Adama urban forests were estimated to produce 19.93 thousand tons of oxygen per year. It was estimated that trees and shrubs remove 188.3 thousand tons of air pollution due to O3, CO, NO2, PM2.5 and SO2 per year. In the city, 35 percent of the urban forest's VOC emissions were from Eucalyptus cinerea and Eucalyptus globulus. Besides, the monetary value of Adama urban forest in terms of carbon storage, carbon sequestration, and pollution removal was estimated to 16,588,470 ETB/yr, 118,283 ETB /yr and 12,162,701,080. 9 ETB /yr respectively.Conclusion: Urban forest of Adama city has significant contribution in terms of enhancing woody species diversity and the regulation of urban environment of the study area. From the management and conservation perspectives, urban forests of the study area needs consolidated interventions in terms of tree planting in bare areas and management works. Hence, reliable commitment should be demanded form the key stakeholders such as government, urban foresters and city dwellers.

Purpose The purpose of this paper is to measure the influence factors of their preferences for urban forest, marginal values of various properties and relative values of different scheme portfolios, thus arriving indirectly at the city residents’ demand for urban forest improvement. Design/methodology/approach This paper, based on the data from the 2015–2017 field survey questionnaire of city residents over the radius of Beijing’s 5th Ring Road, uses the choice experiment method (CEM) to conduct a study of its residents’ demand for urban forest. Findings Beijing’s city residents are generally inclined to accept a relatively low payment of urban forest while hoping to access a relatively high urban afforestation coverage with the construction of relatively many city parks, especially focusing on the specialized park management; the marginal values of biodiversity and greenery coverage are far higher than those of greenbelts in quantity and the maximum marginal value of biodiversity remains as high as RMB29.42, indicating that the city residents do not favor much the number of greenbelts over other aspects but they generally hope to achieve a higher greenery coverage and a richer biodiversity. Research limitations/implications Generally speaking, what Beijing City needs most is not continuing the increase in the number of greenbelts, but engaging in the rational retrofit of its existing greenbelts and optimizing its urban forest structure. Originality/value This paper may provide reference for determining the city residents’ payment criteria for urban forest and will be of equally great significance to developing cities and their urban forest.

Urban and peri-urban forestry has emerged as a complementary measure to contribute towards eliminating urban hunger and improved nutritional security. However, there is scanty knowledge about the composition, diversity, and socioeconomic contributions of urban food trees in African cities. This paper examines the diversity and composition of the urban forest and food trees of Accra and sheds light on perceptions of urbanites regarding food tree cultivation and availability in the city. Using a mixed methods approach, 105 respondents in six neighborhoods of Accra were interviewed while over 200 plots (100-m2 each) were surveyed across five land use types. Twenty-two out of the 70 woody species in Accra have edible parts (leaves, fruits, flowers, etc.). The food-tree abundance in the city is about half of the total number of trees enumerated. The species richness and abundance of the food trees and all trees in the city were significantly different among land use types (p < 0.0001) and neighborhood types (p < 0.0001). The diversity of food-bearing tree species was much higher in the poorer neighborhoods than in the wealthier neighborhoods. Respondents in wealthier neighborhoods indicated that tree and food-tree cover of the city was generally low and showed greater interest in cultivating food (fruit) trees and expanding urban forest cover than poorer neighborhoods. These findings demonstrate the need for urban food policy reforms that integrate urban-grown tree foods in the urban food system/culture.

Abstract Urban wildlife organizations—which include groups focused on wildlife rehabilitation, rescue, removal, advocacy, education, and conflict resolution—have typically been viewed as out of step with the goals of wildlife conservation because of their focus on encounters with individual nonhuman animals, common species, and degraded habitats. The recent shift by large conservation NGOs toward a “humans and nature together” framework, because of its focus on urban natures, has brought the field into discursive relation with urban wildlife organizations. Drawing on a case study of four wildlife organizations in an urban center, this research explores their discourse about human-wildlife relationships in the city, and the challenges and opportunities presented by their emergent intersections.
