Arnebia euchroma (Royle ex Benth.) Johnston, commonly known as ‘Ratanjot’ is an important medicinal plant species and is found distributed in the western Himalaya at elevations ranging between 3200 - 4500 m above sea level. Considering its potent medicinal properties, cultural significance, declining population density and critically endangered status of this taxon, the present investigation was carried out for the assessment of its availability in the natural alpine landscapes of the Spiti cold desert of western Himalaya in Himachal Pradesh (India). We focused our study on its ecological features, population dynamics and performance in natural habitats, so as to formulate conservation plans. In order to achieve the objectives of the present study, a total of 620 areas were set by using a random sampling technique at six different locations where A. euchroma was found distributed naturally. The highest population density was recorded in undulating meadows (5.30 individuals/m2) with a maximum circumference (4.18±1.80cm) at an elevation of 4240 m above sea level, with maximum frequency of occurrence (100%). Ecological surveys revealed that distribution was restricted in specific habitats rich in soil nutrients with high pH (8.025 - 8.37). The significance of the role of various ecological variables is explained in detail in the present paper. Habitat specificity, low population, and anthropogenic pressure justify the rarity status of this taxon in the Spiti valley. The authors discussed different implications to develop appropriate strategies for a long-term monitoring and sustainability of A. euchroma in the Spiti cold desert of western Himalaya
