ABSTRACT

Present study deals with threat assessment, cultivation, sustainable utilization and conservation of 5 threatened plants (Dioscorea deltoidea, Hedychium spicatum, Polygonatum verticillatum, Angelica glauca, Dactylorhiza hatagirea) of Nihri tehsil of district Mandi, Himachal Pradesh Nihri (latitude 31°4 3’12.5” N and longitudes 77°0 7’01.2” E) is a temperate region of Western Himalayas rich in high valued commercially useful plants. Some of plants growing here like Dioscorea deltoidea, Hedychium spicatum, Polygonatum verticillatum, Angelica glauca, Dactylorhiza hatagirea) are unique to this region and heavily demanded by pharmaceutical companies, so they are over-exploited by locals traders As a result natural population of these plants has been declined significantly. In present study threat categorization of these species has been done based on the habitat, distributional range, nativity, wild status of plants, their UV and DMR value. Data analysis shows that among these plants Dactylorhiza hatagirea is critically endangered (having Uv General=0.22 & DMR score =13) followed by Angelica glauca and Dioscorea deltoidea which are placed in endangered category (having Uv General = 0.40 & 0.45 and DMR score= 17 & 21) respectively, followed by Polygonatum verticilatum and Hedychium spicatum which are placed in vulnerable category (with UV General = 0.24 & 0.60 and DMR score =16 & 23) respectively. In order to maintain the harmony between demands and supply in-situ and ex-situ conservation of these plants is need of hour. So, the present study has been attempted to raise nursery, distribute planting material, aware locals for cultivation, sustainable harvesting and utilization of documented plants from March, 2022 to March, 2023.
