A Lidar-based Method for 3D Urban Forest Evaluation and Microclimate Assessment, a Case Study in Portland, Oregon, USA
Urban forests play a crucial role in mitigating thermal stress and building climate change resilience. However, effectively quantifying these benefits is challenging due to the complex nature of urban landscape [1]. Existing tree planting programs often fall short in improving vulnerable communities in need. To address these limitations, this study proposes a novel method for quantifying the microclimate regulation benefits of urban forests. The proposed method combines high-resolution, 3D Lidar remote sensing products with ground truth urban tree survey data. The process starts with using Lidar to delineate the crown boundary of individual trees. Then, zonal statistics are performed on the point clouds for each tree, and a machine learning model is built using the ground truth tree survey data to classify trees based on taxonomic features (Family) and sizes [2]. This result fits in the ENVI-met microclimate simulation model to simulate the combined microclimate effects of different species and sizes of trees [3,4]. The integration of Lidar-based urban forest evaluation with ENVI-met microclimate simulation model is a major advancement. It assesses not only the quantity but also the quality of the urban forest. This approach reliably captures subtle differences and identifies potential risks. Benefits of the method are: Reliability: The method generates accurate and reliable results capturing the subtle microscale differences. Flexibility: This approach is object-based, allowing for more alternative scenarios to be simulated, giving urban planners and managers greater flexibility in decision-making. Scalability: The entire process is automated and can be easily replicated in other parts of the city or different regions, making it scalable and adaptable to various urban environments. This research includes a case study comparing two socio-demographically different communities in Portland, Oregon, USA. Instead of simply suggesting planting more trees, the study provides practical recommendations, including suitable locations, preferred tree species, and projections for the future. As Lidar becomes more accessible and the demand for studying microclimate at the community level grows, this method shows promise for practical applications in urban tree management and climate resilience planning. https://agu.confex.com/data/abstract/agu/fm23/7/8/Paper_1392487_abstract_1225368_0.jpg

A sense of concern for the environment, one of which is by planting tree seeds. On this community service activities this time, we planted tree seedlings in the Citarum Watershed (DAS), in Jelegong village, West Bandung. The location selection was based on the condition of the area which was damaged by human activities, including the conversion of land into a trash can. This tree planting activity has a negative impact on the surrounding environment. This activity was carried out before the pandemic, on November 24-25, 2019 involving the Budi Luhur University Academic Community as a form of concern for the environment. This activity also involves Jelegong Village Community and Officials as well as the TNI who served as the Sector 8 task force. The tree seedlings planted were fruit tree species such as mango, rambutan, jackfruit and others.The number of trees that planted spread across the watershed totaling 150 trees. The one, who is responsibility for the maintenance of this plant ...

Tree planting is one of the very crucial areas in forest sustainability and environmental management that requires a substantial interest in the present millennium. Tree planting is the process of transplanting tree seedlings, generally for forestry, land reclamation, or landscaping purposes (Wikipedia, 2015). It deals with selection of species of tree plants, identification of planting purpose, sourcing of the tree plants, raising the seedlings and planting of the trees among others. A tree plant that is used for environmental remediation is not the same with, the one used for forest sustainability. Hence, the need for identification of the planting purpose and the plant species. Generally, trees help us get oxygen (air) and help in keeping our soil healthy so we can grow food. Trees provide a wide range of forest and forest related products such as timbers, fruits, medicines, beverages, fodders and oils; and life-supporting services like carbon sequestration, erosion control, soil fertility, shade and beautification. However, tree planting in most developing countries is yet to find utility in environmental management and forest sustainability as a result of lack of emphasis on the importance of tree planting and lack of effective policy that would incorporate tree planting into human lifestyle. Against the above background, it becomes pertinent to carry out an investigation on the role and importance of tree planting to forest sustainability and effective environmental management. This work is a descriptive survey and the investigation revealed that lack of emphasis on the importance of tree planting, effective policy, maintenance measures among others are some of the factors inhibiting the utility of tree planting in forest sustainability and environmental management.

Thanks to this educational project we would like your students to engage in a series of activities to help inform and educate Spanish youth on biological, cultural and tourist values of the singular trees and groves. And even make that the city council of your town protects some of those picked by them. At the same time, this project will help them develop some basic and fundamental skills in their learning process, as it is framed in its immediate reality and has a specific purpose: protecting the natural environment. This educational project has been developed for Fundación Félix Rodríguez de la Fuente with the contribution of the project LIFE + from the European Union.

The purpose of this paper was to investigate and compare students' knowledge and attitude towards community's tree ordination before and after attending a tree-ordination promotional training. The sample were 30 undergraduate students majoring in Environmental Education at a university in the northeast of Thailand. The research tools were a tree-ordination knowledge manual, a tree-ordination knowledge test, and the attitude questionnaire. The statistics used for data analysis were frequency, percentage, means, standard deviation, and paired t-test. The results showed that before the promotional training, the students had the tree-ordination knowledge at the fair level. However, after the promotional training, their tree-ordination knowledge increased to the good level. When comparing the mean scores between before and after the intervention, it was found that the students' knowledge on tree ordination after the training was significantly higher than before the training at the significance level of .05. In terms of their attitude towards tree ordination, before the promotional training, the students' attitude was at the fairly agree level, but it changed to strongly agree level after the training. When comparing the mean score between before and after the training, it was found that the students had much more positive attitude after the training than before the training with the significance level of .05. It can be concluded that the designed tree-ordination promotional manual is effective and can be used as a tool for promoting tree ordination in a community. Keywords: Tree ordination; local wisdom; forest preservation; eco-culture.

Demand for timber in Leyte Province continues to increase whilst supplies from domestic sources have contracted following suspension of logging in remaining natural forests. One approach to meet the deficit in timber supplies has been to encourage timber planting by smallholders. A survey was undertaken in four rural communities to help assess present tree planting and management activities of households and their tree planting and management intentions. It was found out that not more than 100 trees are managed by each of about 61 % of the households who have planted trees. There were 88 different species planted or managed by households, but 83 % of the total trees planted belong to only 10 species, including mahogany, ipil-ipil, gmelina and molave. The primary purpose of tree planting is to meet household needs for timber for dwelling construction and fruit production. About 72 % of the total trees being managed by households were planted, as distinct from natural regeneration, wi...
