Plant resources in seven Jeonju City reservoirs: Osongjae, Gisijae, Sunggokjae, Gujujae, Seounjae, Hwanghakjae and Hacksojae

Abstract

The vascular plants of the seven reservoirs of Jeonju City were identified as consisting of 309 taxa; 87 families, 231 genera, 270 species, 35 varieties, and four forms. Eight taxa of endemic Korean plants were identified, including Taxus cuspidata var. caepitosa and Aster koraiensis. Ten taxa of rare and endangered species were identified, including T. cuspidata and Penthorum chinense. A total of 26 taxa of floristic special plants were recorded: class V species (5 taxa) included Magnolia kobus and Prunus yedoensis; class IV species (3 taxa) included Prunus davidiana and Campanula takesimana; class III species (5 taxa) included Acer palmatum and Alisma orientale. The hydrophytes of the seven reservoirs of Jeonju City were investigated and, of a total of 56 taxa, 46 taxa of emerged plants, two taxa of submerged plants, five taxa of floating-leaved plants, and three taxa of floating plants were identified. Thirty-two taxa of naturalized plants were identified. Among these, Sicyos angulatus, Lactuca scariola, Paspalum distichum var. indutum and P. distichum were identified, which are all wild plants that may disturb the ecosystem. The study suggests that these areas require management for the physical removal of these wild plants.
