Paper Title
Diversity and Conservation Strategy of Orchid Species on Karst Land in Mudal River Park Ecotourism, KulonProgo, Yogyakarta

Abstract
Orchids is a group of family Orchidaceae which has a high diversity. Orchid has 25,000 to 35,000 species that have been described, but orchids can only grow under special conditions (microclimate), those are light intensity, nutrition, climate, weather, and mycorrhizae, so they grow as epiphytes, lithophytes, terrestrial or semi-terrestrial. Mudal River Park Ecotourism is located in the Menoreh mountains region and has a form of karst land that contains high calcium, which affects the recovery of vegetation. The Menoreh mountains region has a high diversity of species of orchids. As a tourist area, the right conservation strategy is needed to preserve the orchids in the area. This study aims for knowing the conservation and diversity of native orchids species in Mudal River Park Ecotourism, KulonProgo, Yogyakarta. This study used roaming methods with 10 imaginary plots, identification of samples using the book Orchid of Java by Comber (1990), and analysis of data to determine the abundance of species. Based on research, 15 species of orchids were found. Vanilla planifoliawas known to have the highest density of 110, while the highest frequency were Acriopsisliliifolia, Dendrobiumcrumenatum, and Vanilla planifolia, which is 0.7. Vanilla planifolia was also known to have the highest important value of 46.24. In the region also found a new track species, namely Crepidiumridleyi. Orchids were one of the key species in an ecosystem that can affect the presence of flora and fauna in them. Orchid species were able to create specific microclimates that can accommodate the diversity of flora and other organisms. Keywords - Conservation, Ecotourism, Karst, Orchid.
