Himalayan yew (Taxus baccata) is categorized as endangered species due to over usages and slow growth attributes. The conservation of yew remains a prime focus amongst botanists and environmentalists considering its wide applicability for humans. The plant was collected from the terrains of Tirthan valley, Himachal Pradesh, India and its acclimatization in non-native conditions was observed. It was observed that the survival of the plant was really difficult in its alien conditions but under controlled conditions it thrived well but the growth of the plant was very slow. Our main objective was to establish the plantlets of Taxus at the experimental site for attempting various conservation strategies which were achieved in the end. The plant growth culture chamber or tissue culture rooms, thus acted as a place where the plant thrived well which can be taken further to laboratory environment by following gradual acclimatization process.
Key words : Taxus, yew, conservation, acclimatization, non-acreage, modified niche
