  • This study surveyed the vascular flora present in abandoned paddy field type of 237 forest wetlands in Korea to provide baseline data for conservation, management, and monitoring and to support preparation for damage and climate change. The study period was from April 2015 to November 2021. The vascular flora of 237 forest wetlands by abandoned paddy field type were identified to consist of 128 families, 510 genera, 1,022 species, 27 subspecies, 87 varieties, 10 forma, and 1,146 taxa. 4 taxa were identified as grade II endangered wild plants, 185 taxa were identified as northern lineage plants of the Korean Peninsula, 43 taxa were endemic to the Korean Peninsula, and 58 taxa were rare plants as designated by the Korea Forest Service. Further, 296 taxa were floristic target plants and there were 86 taxa of invasive alien plants. According to wetland preference, 79 taxa (6.9%) were obligate wetland plants, 103 taxa (9.0%) were facultative wetland plants, and 61 (5.3%) taxa were facultative plants. Additionally, 66 taxa (5.8%) were facultative upland plants, and 837 taxa (73.0%) were obligate upland plants.

The specific plants by floristic region were 16 taxa including Asplenium sarelii, Pyrrosia petiolosa, Vitex negundo var. incisa and so forth. The target plants adaptable to climate change were 2 taxa including Lespedeza maritima and Carpesium macrocephalum, and the plants with approval for delivering oversea were 4 taxa including Exochorda serratifolia, Glycine soja, Lespedeza maritima and Weigela subsessilis. The naturalized plants were 51 taxa including Phytolacca americana, Viola papilionacea, Lamium purpureum and so forth. The invasive alien plants were 3 taxa including Ambrosia artemisiifolia, Aster pilosus and Lactuca scariola. NI(Naturalized Index) was 12.4% of all 411 taxa of surveyed flora in this study and UI(Urbanized Index) was 15.9% of all 321 taxa of naturalized plants in Korea. Potentilla discolor in rare plant, Philadelphus schrenkii in endemic plant and Dictamnus dasycarpus in specific plant were established the conservation plan. Whereas, invasive alien plants such as Ambrosia artemisiifolia, Aster pilosus and Lactuca scariola should be removed as soon as possible. The damaged sites in Seoak District were divided between wildfire area and farmland. To restore a forest fire site, we will have to apply a natural renewal and community planting. In case of farmland, we will have to do ecological planting using native species and constrcut a forest wetland.

  • Sonjook island is located Samsan-myeon, Yeosu-si, Jeollanam-do. All of field information was collected from January 2001 to November 2002. The vascular plants recorded as total 584 taxa, 5 forms, 60 varieties, 519 species, 365 geneta, 113 families. Sonjook islands shows the typical vegetations including the lower area of temperate region of Korean peninsula and evergreen broad-leaved forests, Pinus thunbergii forest. The Korean endemic plants were recorded as 13 taxa (5 variety, 8 species, 10 genera, 10 families), 4 taxa as rare and endangered plants (Psilotum nudum (L.) Griseb., Milletia japoniea A. Gray, Arisaema negishii Makino, Sarcanthus scolopendrifolius Makino). The naturalized plants were 23 taxa (20 genera, 9 families, 8.2% among the total naturalized plants in Korea. This area is ecologically important place that Korea endemic plant, rare and endangered plants ranges much than area. On the one hand, threat from degraded by environmental pollution that share of naturalized plant rises gradually augment. Strong conservation policy and development control should be considered.
