The aim of this study was to provide basic guidelines for conservation and management of endangered plants in the national parks of Korea. Pedicularis hallaisanensis Hurus (Scrophulariaceae) is considered a second-class endangered species by Korean government and it is listed as a EN (Endangered) species in Red Data Book of Korea. We analyzed ecological conditions of P.hallaisanensis habitats based on vegetation properties and soil characteristics. This species which is known to inhabit in sub-alpine grassland of Korea and its population was located at an elevation of 1,374m to 1,916m. In the study sites, soil organic matter, total nitrogen, soil moisture, available phosphate, exchangeable potassium, exchangeable calcium, exchangeable magnesium, exchangeable sodium, cation exchange capacity and soil pH were 2.55-22.48%, 0.10-0.71%, 17.20-57.57%, 1.98-7.77ppm, 0.05– 0.22cmol+/kg, 0.78-18.21cmol+/kg, 0.25-0.76cmol+/kg, 0.08-0.13cmol+/kg, 5.35-26.48cmol+/kg and 5.69-7.55 respectively. Additionally, the genetic variation and structure of three populations were assessed using microsatellite markers.The genetic diversity of P.hallaisanensis among populations was the highest in Mt. Gayasan. Analysis of molecular variance (AMOVA) apportioned among population and within population variations, showing more genetic variance (52%) occurred in within population, and 48% variation among populations. Lastly, we developed predicted distribution model based on climate and topographic factors by applying SDMs (Species Distribution Models). Consequently, current status of P. hallaisanensis habitats were very fragile and vulnerable with the pressure of the vegetation and the climate change constantly threatening the species’ survival. Therefore, it is essential to establish in situ conservation strategies for protecting natural habitats and to require exploring potential and alternative habitats for reintroduction.
