“…Plant cover of the pioneer cemetery helps reduce surface run-off by an estimated 452 cubic meters a year. This indicates that the Rectorship garden has a significantly higher capacity of potential runoff retention rate than the cemetery because the storm water runoff rate is estimated to be nearly 7,018.9 cubic meters in the garden (Coskun Hepcan & Hepcan, 2018).…”

Objective:The objective of this study was to quantify four regulating ecosystem services; carbon sequestration and storage, avoided run-off, air pollution removal by trees and oxygen production in the Eugene Pioneer Cemetery, OR (USA). Material and Methods:For data preparation the field data of trees was collected on paper data sheets. Collected data in the field were land-use type, tree species, diameters of breast height-DBH (cm), total tree height (m), live crown height (m), crown base height (m), and crown percent missing. In data analysis I-Tree Eco model version 6 developed by the U.S. Forest Service, Northern Research Station was used. Results:The gross sequestration of the cemetery trees is about 7,136 metric tons of carbon per year. Trees in the cemetery were estimated to store 1,610 metric tons of carbon. The trees and shrubs of the cemetery help to avoid runoff by an estimated 452 cubic meters a year. It was estimated that trees remove 143,9 kilograms of air pollutions. Trees in the cemetery were estimated to produce 19,03 metric tons of oxygen per year. Conclusion:This study recommends large green areas (large permeable surfaces) and trees with large crowns in the planting design as a better solution for regulating ecosystem services. ÖZAmaç: Bu çalışmanın amacı, Eugene Pioneer Mezarlığı, Oregon (ABD) 'de, dört düzenleyici ekosistem servisini ölçmektir; bunlar karbon tutulması ve depolanması, yüzey akışının önlenmesi, hava kirleticilerinin tutulması ve oksijen üretimidir. Materyal ve Yöntem:Veri hazırlama aşamasında ağaçlara ilişkin ölçülen veriler kâğıt üzerine kaydedilmiştir. Arazi kullanım türü, ağaç türleri, ağacın göğüs yüksekliğindeki çapı-DBH (cm), ağaç yüksekliği (m), canlı taç yüksekliği (m), tacın yerden yüksekliği (m), kayıp taç yüzdesi. Veri analizinde I-Tree Eco model versiyon 6 kullanılmıştır.Araştırma Bulguları: Mezarlıktaki ağaçlar brüt olarak yılda yaklaşık 7.136 ton karbonu tutmakta ve 1.610 ton karbonu depolamaktadır. Alandaki bitkiler yılda yaklaşık 452 m 3 bir yüzey akışı engellemekte ve 143,9 kg hava kirleticisini ortadan kaldırmaktadır. Son olarak mezarlıktaki ağaçların yıllık 19,03 ton oksijen ürettiği hesaplanmıştır.Sonuç: Bu çalışma, daha iyi düzenleyici ekosistem servislerini üretebilmek için geniş taçlı ağaçların kullanıldığı, büyük bölümü geçirgen olan geniş yeşil alanların tasarımını önermektedir.

University campuses provide a variety of ecosystem services (ES) that play an important role in both physical and mental benefits for students. However, the importance and actual service performance of ES in universities were not clearly perceived in Vietnam. This study was conducted to fill these gaps with the objectives of (1) assessing students' perceptions of the importance of ecosystem services on their university campus and (2) assessing students' satisfaction with these ecosystem services. Using the interview method, the study collected research data from 210 students at Can Tho University (CTU), a large university in Vietnam. The results of the study have confirmed the importance of ecosystem services such as trees, lawns, water bodies, and buildings on CTU's campus. With modern design, buildings play an important role in creating space to organize formal classes, self-study, and group work for students. Green spaces not only improve air temperature and bring high aesthetic value, but they are also habitats for many species of animals and plants. Most students were very satisfied with the ES provided by the CTU's campus. However, the functions of the grass and water bodies ecosystem need to be improved, as the student satisfaction with these ES was significantly lower than the value they expected. The results of analyzing the importance and satisfaction of ES will be a useful basis for making decisions on planning and developing ecosystems. This is a new research direction in Vietnam that needs continued research and application. Doi: 10.28991/CEJ-2024-010-01-015 Full Text: PDF

“…Additionally, various empirical methods were also used for ecosystem service valuation. For example, carbon sequestration and runoff retention were measured as representative regulating services (Coskun Hepcan and Hepcan, 2018). Number of plant and animal species found on study sites were evaluated and used as indicators for supporting services (Baral, Guariguata, and Keenan, 2016).…”

Ecosystem service assessment of green roofs in Bangkok

Green roofs are constructed ecosystems that can provide four main types of ecosystem services (regulating, provisioning, cultural, and supporting services). However, most green roof studies have focused on the regulating services and each ecosystem service type was usually evaluated separately. Moreover, there is a lack of assessment tool that can provide comparable outputs of total and different ecosystem services on green roofs, resulting in the difficulty to improve ecosystem service provision by green roofs. Therefore, this research aimed to (i) assess four main categories of ecosystem services provided by seven green roofs in Bangkok using direct measurement techniques and a novel rapid assessment checklist, (ii) investigate perception of people on green roofs and their ecosystem services using questionnaires and interviews with three groups of respondents; 259 university students, 90 workers, and five experts, and (iii) create a Green roof ecosystem service game for sharing the green roof knowledge with the public and concerned stakeholders. The results from the direct measurement showed that the selected green roofs in Bangkok could provide a combination of four main types of ecosystem services. The results from the rapid assessment checklist showed that the ecosystem service scores of seven sites ranged from 48 to 74 points from a maximum of 100. The green roof on Anantara Siam Bangkok hotel received the highest score of total ecosystem services of 74 points. Tradeoff and synergy among different green roof ecosystem services were observed. Different ecosystem services were influenced by green roof structure and design and management. Through the questionnaires and interviews, gas regulated was ranked as the first priority of ecosystem services ranked by the university students while the workers and experts cited climate regulation as the ecosystem service of the highest priority. Only 44% of the respondents knew the definition of the green roof. All of these results were used to create a series of green roof games which were used during gaming sessions with university students and experts. The results from pretest- posttest analysis from 18 gaming sessions, 449 participants, showed a significant improvement of green roof knowledge through playing the games. In summary, this research has contributed valuable knowledge of ecosystem services on green roofs by providing a convenient framework to assess ecosystem services and an innovative gaming and simulation for sharing the knowledge and raising awareness of the green roof ecosystem services.
