Abstract

The objectives of this study were to determine the dominant frequency of plant species and provide useful information
towards the conservation management of animal feed in grazing areas, Hiroshima, Japan. The numbers of plant species
were 32 and 21 in spring and summer, respectively. The appearance frequency of plant species more than 50% in the spring,
consist of Veronica arvensis (75.57%), Trifolium repens (73.86%), Paspalum dilatatum (69.32%), Lamium purpureum (68.75%),
Trifolium dubium (65.34%), Cerastium glomeratum (63.64%), whereas in summer, it consists of Paspalum notatum (98.30%),
Trifolium repens (81.25%), Paspalum dilatatum (78.98%), and Kyllinga brevifolia (74.43%). It was observed that the frequencies
of plant species were 16.64 and 21.55 cm; vegetation cover rates were 77.18 and 81.36%; chlorophyll content were 41.72 and
36.28 mg/g Fw and species numbers were 17.91 and 10.18, in spring and summer, respectively. Findings of this research
propose that Trifolium repens (clover), Rumex japonicus (weed), and Paspalum dilatatum (grass) are dominant species in the
studied areas that can be utilized as animal feeds.
