Abstract

The purpose of this study was to identify the natural habitat of Bulbophyllum inconspicuum Maxim. in Hongdo, Jeonnam Province, South Korea. A field investi gation was conducted between May 2019 and May 2021. The growth of B. inconspicuum species was confirmed in three known regions based on National Survey on the Distribution of Endangered Species. Additionally, in the area investigated, 37 new regions harboring B. inconspicuum were detected. The newly observed B. inconspicuum grew naturally on Quercus mongolica, Rhaphiolepis indica var. umbellata, Carpinus turczaninowii, and rocks. Most of them were found on southeast and southwest slopes with altitude above 250 m. As few as 10 up to hundreds of B. inconspicuum were found in clusters. Close to their habitat, Calanthe sieboldii Decne. ex Regel, C. aristulifera Rchb. f. and C. × kibanakirishima Maek. were also found. As Hongdo is an island, multiple endangered species were found together. Thus, once the habitat of a certain plant is discovered, it is very likely that illegal collection of several other species will also occur. Proactive internal and external measures are needed to preserve these species.
