Abstract

Anggrek epifit (Orchidaceae) hidup pada pohon inang, namun tidak bersifat parasit. Kelimpahan anggrek epifit ditentukan oleh zona distribusi dan karakteristik pohon inang. Penelitian yang dilakukan di Hutan Sumber Pawon, Desa Tempurejo, Kediri ini bertujuan untuk mengetahui tingkat keanekaragaman, karakteristik pohon dan zona distribusi anggrek epifit pada pohon inang. Metode pengambilan data dengan systematic sampling dengan kombinasi metode jelajah pada sepanjang jalur pengamatan berdasarkan keberadaan jenis anggrek epifit pada pohon inang dengan mengambil 9 titik yang representatif. Penelitian ini dibuat 27 plot pengamatan berukuran 10 x 10 m. Data karakteristik pohon inang dan zonasi distribusi anggrek epifit diambil secara observatif. Analisis data anggrek epifit digunakan indeks nilai penting dan indeks keanekaragaman Shannon-Wiener secara deskriptif kuantitatif, serta metode ordinasi dengan CANOCO 4.5 for Windows. Berdasarkan hasil penelitian di Hutan Sumber Pawon didapatkan 3 jenis anggrek epifit dan 5 jenis pohon inang. Anggrek epifit yang didapat antara lain Cymbidium bicolor, Dendrobium crumenatum, dan Vanda retusa. Pohon inang yang didapatkan antara lain Alstonia scholaris, Artocarpus elasticus, Bischofia javanica, Ficus elastica, dan Samanea saman. Adapun, didapatkan tingkat keanekaragaman anggrek epifit adalah rendah (H’=0,274). Indeks nilai penting anggrek epifit dengan kategori tinggi (175,21%) pada D. crumenatum dan kategori rendah pada C. bicolor (18,45%) dan V. retusa (6,34%) yang menunjukkan adanya dominansi pada D. crumenatum. Anggrek epifit lebih berlimpah pada zona 4. Anggrek epifit memiliki preferensi dengan karakter pohon yang tinggi (28,65 m-33,65 m), DBH batang besar (165,61 cm-175,80 cm), dan tutupan tajuk yang tertutup (51%-75%).

Epiphytic orchids (Orchidaceae) are types of orchids that live on their host trees. The abundance of epiphytic orchids is determined by the distribution zone and characteristics in the host tree. The research, which was conducted in Sumber Pawon Forest, Tempurejo Village, Kediri, aims to determine the level diversity, tree characteristics and distribution zone of host trees as well as environmental factors that influence them. The data collection method used systematic sampling with a combination of exploration methods along the observation path based on the presence of epiphytic orchid species on the host trees by taking 9 representative points. This study used 27 observation plots measuring 10 x 10 m. Data on host tree characteristics and distribution zone of epiphytic orchids were taken by observing. Analysis of epiphytic orchids data used the important value index and Shannon-Wiener diversity index in a quantitative descriptive manner, and ordination method using CANOCO 4.5 for Windows. Based on results of research in Sumber Pawon Forest, there were 3 types of epiphytic orchids and 5 types of host trees. Epiphytic orchids include Cymbidium bicolor, Dendrobium crumenatum, and Vanda retusa. The host trees include Alstonia scholaris, Artocarpus elasticus, Bischofia javanica, Ficus elastica, and Samanea saman. Meanwhile, the level of diversity epiphytic orchids was low (H’=0,274). The important value index of epiphytic orchids is high category on D. crumenatum and low on C. bicolor and V. retusa which indicated the dominance of D. crumenatum. Epiphytic orchids were mostly found in zone 4 and few were found in zone 5. The preference for host tree selection by epiphytic orchids with characteristics as high tree (28,65 m-33,65 m), large DBH (165,61 cm-175,80 cm), and closed canopy cover (51%-75%)
