Hyla suweonensis is an endemic species and is designated as the only endangered species I among amphibians in 2012 by the Ministry of Environment, however studies about its habitat are lacking. This study was carried out to analyze habitat of H. suweonensis based on the spatial information using Maxent (Maximum entropy model as a species distribution model. We detected 45 present points until 2013 and 10 environmental variables by literature review for the model. The results showed that $429km^2$ (0.95%) of the study area, which was about 7.75% of the total agricultural area, was high possible habitats of H. suweonensis. The habitat of H. suweonensis was analyzed by over $1km^2$ rice paddy fields that were lower elevations, flat slopes, and not fragmented. The distance from forests and rivers was identified as a factor that affects its habitat possibilities. In order to conserve H. suweonensis, a large area of rice paddy fields should be preserved, and especially the area around forests and rivers would be required more intensive management. In addition, to compensate for degraded habitats of H. suweonensis in urban areas like as Suwon city, considering integrated watershed management strategy could be effective in the perspective of ecological habitat network of H. suweonensis.

On August 21, 2023, the National Institute of Ecology reported the sighting of an invasive slug resembling Limax maximus Linnaeus, 1758. near Bambat Tree Frog Park, Suwon-si, Korea. This slug is known for its aggressiveness. Specimens were collected around the park and from nearby farms. Through barcoding analysis and sequence comparison, it was identified as L. maximus, confirming its presence in Republic of Korea, alongside two previously identified Limax species, Limax flavus Linnaeus, 1758 and Lehmannia marginatus O. F. Müller, 1774. This study represents the first documented report of L. maximus in the country.
