The vascular flora of grassland in Sagok-ri, Wasoo-ri, and Yukdan-ri, Kimwha were composed of 39,28, and 32 species respectively.
The most important of which were Arundinella hirta hirta in Wasoo-ri and Yukdan-ri and Miscanthus sinensis in Sagok-ri.
Theses two species contributed greatly to the standing crop of live material which was in excess of 146.4/m^2 throughout the growing season.
The daily throught the growing season ranged from 1.04g/m^2(Yukdan-ri) to 4.12g/m^2(Sagok-ri).
Among grasslands in Kimwha, phosphorous and water content of Sagok-ri were also high.
