(Januari 2020: Submitted; Februari 10th 2020; Revised) ABSTRACT An assessment of the conservation status of all known plant species is a foundational step to guiding conservation action. It is highlighted as a global conservation priority in the GSPC (Global Strategy for Plant Conservation) Target 2. Ferns and lycophytes are undoubtedly under threat as humans have caused the destruction of natural habitats and unparalleled species extinction. Cibotium arachnoideum (C. Chr.) Holttum (Cibotiaceae), is a large terrestrial fern with an upright or prostrate caudex having densely shining reddist-brown of rigid hairs and having one or two pairs of sori with two indusia forming a small cup on each lamina-segment. This species is strictly distributed in the Malesian region. The aim of this study is to assess conservation status of C. arachnoideum by using 2001 IUCN Red List Categories and Criteria (version 3.1). Population size was estimated and observed both based the specimens deposited at Herbarium Bogoriense and field study in Sumatra. The area of occupancy (AOO) of this species is 44 km2. Cibotium arachnoideum is occured in severely fragmented locations in West Malesian region, in 2 locations, viz Sumatra and Borneo. Sumatra has only two sub population and Borneo has nine sub population. The number of mature individuals reported were only found 372 in one location of North Sumatra, and 19 individuals in one location of Bengkulu. Therefore, C. arachnoideum is proposed as an endangered species, En: B2ab (i,ii,iii) + C2a (i). Key words: Area of occupancy (AOO), Cibotium arachnoideum, conservation status, tree fern, extent of occurrence (EOO)
