KEANEKARAGAMAN JENIS TUMBUHAN PAKU EPIFIT (PTERIDOPHYTA) DI KECAMATAN SUKADANA KABUPATEN KAYONG UTARA PROVINSI KALIMANTAN BARAT

Abstract

Epiphytic ferns are plants from the Pteridophyta Division which live attached to various other plants and are one of the characteristics of tropical rain forests. This study aims to determine the diversity of epiphytic fern species found in the forest area of Sukadana District, North Kayong Regency, West Kalimantan Province. The research was conducted from September to November 2022. The research locations were Simpang Tiga Village, Sejahtera Village, and Pampang Harapan Village. Method research using Purposive Sampling. Epiphytic fern data were collected using the multiple plot method with a size of 10x10 meters in 5 plots, and the distance between plots was 10 meters at each location. The maximum height for sampling epiphytic ferns on trees is 5 meters. The results of the study there were 10 types of epiphytic ferns namely Asplenium nidus, Asplenium sp, Davallia denticulata, Drynaria sparsisora, Drynaria quercifolia, Vittaria angustifolia, Pyrrosia lanceolata, Pyrrosia piloselloides, Nephrolepis falcata and Phymatosorus scolopendria. The diversity of epiphytic fern species at the study site was classified as moderate with species diversity index values ranging from 1.447 to 1.759. The results of the statistical analysis of Hutcheson's t-test found that between locations there were differences and similarities in the diversity of epiphytic ferns in the three locations.
