本 연구는 濟州道內 放救用 野草地(마을共同收場)에서 野草類의 植生 및 收量性을 조사하여 草地改良 및 野草地의 利用度 增進을 위한 基鍵資料로 活用코자 放牧期間인 7 月부터 9 月까지 수행되었으며 quadrat method를 利用하여 조사한 結果는 다음과 같다. 1. 野草의 總草種은 64種으로 未本科 13草種, 두과 8草種, 엉거시科 12草種, 그리고 기타 31草 종으로 대부분 多年生 草類였다. 2.. 식생적性率은 띠 (Imperata cylindrica) 32.7%, 고사리 (Pteridium aquilinum) 18.9%, 억새 (Miscanthus sinensis) 8.4% 順이었고, 科別로는 未本科草種이 47.5%를 차지하였다. 3. 野草地의 l0a當 乾物收量은 7月이 160kg, 8月이 200-400kg, 9月 이 400-1,000kg으로 평균收量은 383 kg였으며, 生草收量은 평균 1,030kg으로 生育이 進行되면서 점차 증가하였다.

A vegetation survey of the native pasture was conducted in Cheju from July to September, 1980. The purpose of this investigation were, to determine the botanical composition of the native pasture and to estimate how they can be improved to the feed resources of livestock industry. The results obtained are summarized as follows: 1. Grass species existed in native pasture were 64 species with Pwceae 13, Fabaceae 8, Carduacea 12 and other 31. Most of them were identified as perennial grasses. 2. Botanical composition of major grass species were Imperata cylindrim 32.7 %, Pteridium aquilinum 18.9 70, Miscanthus sinensis 8.4 %, and Arternisia japonicn 2.8 % respectively. 3. The average dry matter yield of forage taken on the native pasture was 383 kg per 10a and these yields were increased as the growing stages progressed. 4. Seasonal distribution of edible plants were increased as the growing stages progressed.
