Abstract

Exploration of epiphytic orchids is very important at this time because the natural habitats of the orchids have begun to be damaged due to the forest conversion into plantations. Epiphytic orchids is a plant that grows upon another trees are scattered in limited, permanent and converted production forests. However, the expansion of coconut, clove and cocoa plantations has resulted in a narrowing of the forest area, resulting in reduced natural habitat for epiphytic orchids. The study aimed to establish the species of epiphytic orchids in Sula Islands, North Maluku. The study used a survey method with a descriptive approach and plots were determined by purposive sampling. The results found 6 species of epiphytic orchids in 8 plots i.e. Cymbidium finlaysonianum, Grammatophyllum scriptum, Trichoglottis latisepala, Brachypeza sp., Pomatocalpa spicata, and Aerides sp. Epiphytic orchids, C. finlaysonianum dominate the forest area reaching 77,29% respectively. There were 9 host trees that had been found, i.e Shorea sp., Cythea sp., Mangifera indica, Heritiera sp., Thesphesia macrophylla, Artocarpus sp., Calophyllum inophyllum, Ficus sp., and Cocos nucifera.

INTISARI Kegiatan eksplorasi anggrek epifit saat ini sangat penting dilakukan karena rusaknya habitat alami disebabkan alih fungsi hutan menjadi lahan perkebunan. Anggrek epifit yang sifatnya menempel pada pohon tersebar di hutan produksi terbatas, hutan produksi tetap, dan hutan produksi dapat dikonversi. Perluasan areal perkebunan kelapa, cengkeh dan kakao berdampak menyempitnya areal hutan sehingga berakibat berkurangnya habitat alami anggrek epifit. Penelitian bertujuan mempelajari jenisjenis anggrek epifit di Kepulauan Sula, Provinsi Maluku Utara. Hasil survey telah ditemukan 6 spesies anggrek epifit pada 8 plot antara lain Cymbidium finlaysonianum, Grammatophyllum scriptum, Trichoglottis latisepala, Brachypeza sp., Pomatocalpa spicata, dan Aerides sp. Anggrek epifit C. finlaysonianum mendominasi kawasan hutan mencapai 77,29%. Terdapat 9 pohon inang sebagai habitat alami anggrek yang ditemukan meliputi Shorea sp., Cythea sp., Mangifera indica, Heritiera sp., Thesphesia macrophylla, Artocarpus sp., Calophyllum inophyllum, Ficus sp. Terdapat 9 pohon inang sebagai habitat alami anggrek yang ditemukan meliputi Shorea sp., Cythea sp., Mangifera indica, Heritiera sp., Thesphesia macrophylla, Artocarpus sp., Calophyllum inophyllum, Ficus sp. dan Cocos nucifera
