A Vegetation analysis of terestrial fern in kemuning tea garden in ngargoyoso village, Indonesia

Kemuning Tea Garden in Ngargoyoso Village is a beautiful area with many tourist destinations. Therefore, in addition to the activities of local people as tea farmers, many outsiders come as tourists. This area has abiotic factors that are suitable for the growth of various types of plants, one of which is ferns, especially terrestrial ferns. This study aims to determine the composition of terrestrial fern vegetation in the kemuning tea garden area. The method used was purposive sampling method, with 6 plots in 3 Stations with different heights: Station 1 (800 - 900 m asl), Station 2 (900 - 1000 m asl), and Station 3 (>1000 m asl). This study obtained 9 species of terrestrial ferns: Pityrogramma calomelanos, Adiantum raddianum, Pteris ensiformis, Pteris biaurita, Christella dentata, Nephrolepis exaltata, Dicranopteris linearis, Lycopodiella cernua, and Dryopteris dilatata; that belong to 3 families: Polypodiaceae, Gleincheniaceae, and Lycopodiaceae. The study results show that the type of Nephrolepis exaltata gets the highest INP value, which is 92,88 %. While the lowest INP index is obtained by Pityrogramma calomelanos, which is 9,52 %. The diversity index obtained by the Shannon-wiener formula is 1,85; which means that the diversity in Kemuning Tea Garden is moderate. These findings highlight the importance of adaptive vegetation management in tea plantation landscapes to maintain fern diversity while supporting sustainable agroecosystem functions.
