The Indian Himalayan Region (IHR) is considered as storehouse of diverse group of medicinal plant species. Unsustainable in-situ harvesting practices coupled with climate change have posed a serious threat on a number of native and endemic medicinal plants including Angelica glauca and Heracleum candicans (Family-Apiaceae). Ex-situ cultivation of these Endangered species in suitable agro-climatic zones is recommended as conservation strategy. This book comprises of five chapters provides the first hand information on mass multiplication and production technology of these species. The results of experimental trials on seed biology, production of Quality planting materials through seeds and vegetative propagation, cultural practices, phenology, biomass, productivity and post cultivation evaluation of germplasm have been presented in detail. Applications of the results for developing an appropriate strategy for mass scale production and conservation of these species are suggested.
