| Abstract | This study examined the distribution and diversity of street trees along sidewalks in the roads of Nakhon Ratchasima City Municipality (NCM), Thailand, in response to the rapid urbanization that has led to the loss of green spaces, declining air quality, and increased vulnerability to PM2.5 pollution. Data was collected using Google Street View and field surveys conducted from November 2021 to January 2022. Each sidewalk of NCM roads was plotted by sampling in every 1 km. to measure treepresence. The surveyed data modified from Office of Natural Resources and Environmental Policy and Planning (ONEP), was converted to excel program for tree diversity analysis-based Shannon-Wiener Index (S-W I). As a result, there were a total of 1,556 trees, 171 tree species (they were identified by genus and species-based Forest Herbarium of Department of National Parks, Wildlife and Plant Conservation), and S-W I of 28.029 (average 3.817). The highest sum and average of S-W I (2.551, 0.159) were found in Phonlan Rd. and the lowest sum and average of S-W I (0, 0) were found in 3 roads: Vatcharasarid Rd., Kudan Rd. and Det Udom Rd. The S-WI score for these three roads was 0, indicating the presence of only one species. Based on these results above, they could be assessed that at least 1 tree and tree species would occur every 1-2 km on sidewalk in NCM road. Moreover, Among the recorded species, one was listed as endangered (EN) on the IUCN Red List, and ten were identified as exotic species.Consequently, findings provide critical insights for enhancing urban greenery and guiding green city initiatives to support planning green space network (GSN) in NCM roads, for example, 3 dominant species: Tamarindus indica, Pithecellpbium dulce, and Murraya paniculata will be recommended on the Phonlan road etc. |
