We investigated to analyze the ecological changes of plants in the Wolyoung wetland conservation area from August 2014 to September 2015. The vascular plants investigated in the 2011 literature are 153 taxa(50 families, 110 genera, 136 species, 16 varieties, 1 form). Field survey in 2015 was 208 taxa(66 families, 145 genera, 182 species, 1 subspecies, 23 varieties, 2forms). In the 2015 survey, most vascular plants were composed of dicotyledons. Also, naturalized plants of vascular plants were investigated as 8 taxa(3.85%). Gramineae was the most abundant in 21 taxa, Rosaceae and Compositae were found in 15 taxa. In 2015, the number of vascular plant increased in 55 taxa, and the naturalization plant was increased in 5 taxa than 2011. The reason why number of vascular and naturalization plant increased is disturbance for increase of visitors, wetland succession, landization, etc. The Wolyoung wetland consists of four small wetlands. The vascular plants of Wolyoung wetland were investigated as follows: 1 wetland 152 taxa, 2 wetland 102 taxa, 3 wetland 89 taxa, and 4 wetland 99 taxa. Among the life forms of vascular plants, the Dormancy form showed a high distribution of G(Geophyte) in 2011 and a high distribution of H(Hemicryptophytes) in 2015. Among the Propagation form, Radicoid form showed the type of R5(taxa without lateral spreading) > R3(taxa with the smallest lateral spread rhizome) > R2,3 in both 2011 and 2015. Among the Propagation forms of vascular plants, the Disseminule form was investigated in order of D4(plants disseminated by gravity) > D1(plants disseminated by wind and water) > D2(plants disseminated by animals and human) in both 2011 and 2015. Growth form of vascular plants was surveyed in order of e(erect form) > t(crowding form) > ps(rosette-erect form) in both 2011 and 2015. Especially, the increase of crowding form(t) and branching form(b) reflects the characteristics of Gramineae and Cyperaceae that are major dominant Family of wetland vegetation, and gradually shows the typicality of wetland vegetation.

The Shinbulsan wetland, located in Yangsan-si, Gyeongsangnam-do, South Korea, was designated as a conservation area in 2004. The area was monitored from 2015 to 2019 to investigate the community characteristics and changes of benthic macroinvertebrates. Between 2015 and 2016, several insects of the orders Ephemeroptera, Odonata, and Hemiptera were identified, but their numbers decreased significantly in 2017 and 2018 following the loss and recovery of the moor owing to drought. During this period, there were relatively more insects of the order Diptera. Within this order, three functional feeding groups, gathering-collectors, plant-piercers, and predators were investigated. Predator species were the most abundant (83.3%), whereas gathering-collectors accounted for the largest proportion of individual insects (50.5%). Between 2015 and 2016, when the moors were stable, groups I and III had the highest community stability. After 2017, when the moors had dried up, group III effectively disappeared because of its lower relative resistance and resilience, and only taxa belonging to group I remained. The results of this study indicate that benthic macroinvertebrates that adapt early during moor formation inhabit the Shinbulsan wetland.
