According to previous research on evaluating vegetative value of wetland and RAM evaluation targeting the man-made wetland in Gunsan, Gunsan Reservoir and Gongchang Reservoir had been found to have satisfactory results while Anjeong Reservoir and Changan Reservoir had been found to have unsatisfactory results. Aimed at those reservoirs, a vegetation survey was conducted to analyze differences in terms of flora and growth habit. As for the flora, Gunsan Reservoir ranked first with 433 kinds of plants, followed by Gongchang Reservoir with 306, Changan Reservoir with 176 and Anjeong Reservoir with 167. As for specific plant species by floristic region, it was identified that Gunsan Reservoir had 18 species, larger than other wetlands and also, it had more species of naturalized plants than others. This phenomenon is related to various wetland environments resulted from wider area of Gunsan Reservoir. In the case of dormancy form, hemicryptophytes were mainly distributed in Gunsan Reservoir and Gongchang Reservoir while annual plants were mainly distributed in Anjeong Reservoir and Changan Reservoir with heavy disturbance.

This study carried out a survey to utilize basic data for the conservation of northern lineage plants that are vulnerable to climate change, targeting algific talus slope of a specific forest biodiversity region in Yeotan-ri, Jeongseon-eup, Jeongseon-gun, Gangwon-do. The survey was conducted by dividing the wind hole into 625 m² inside and 6,925 m² outside based on the wind hole.

This was found to be about 7% of 4,724 species of vascular plants in Korea. Plants endemic to the Korean peninsula were identified as 19 taxa, including Syringa fauriei, and 11 taxa for rare plants designated by IUCN. Critically endangered grade (CR) was Paeonia obovata 1 taxa, Endangered grade (EN) was Forsythia saxatilis and Prunus choreiana 2 taxa. A total of 78 taxa were florisitc target species, and 19 taxa were classified for indicator plants in the limestone area. As for alien plants, 20 taxa such as Taraxacum officinale were identified, and the naturalization rate was 6.04% and the urbanization rate was 5.33%. Geographical plants of the study area are 2 taxa of Syringa fauriei and Syringa villosa subsp. wolfii.
