Taxus is a small to medium sized tree, with red ‘berries’ (seed covered by arils), valuable for taxol or paclitaxel extraction used in the preparation of anti-cancer drugs (breast cancer and ovarian cancer), kaposi’s sarcoma (an AIDS related cancer) and over 20 such other indications. It is an evergreen tree found in the temperate forests with an altitude ranging between 1500 m to 3000 m. The worldwide demand of the taxol is 800–1000 kg annually. Around 2 to 3 million kg of biomass is harvested annually where as the sustainable rate of harvesting is estimated to be 0.6 million kg per year. Although, the endophytes isolated from the Taxus when cultured in the medium are found to grow taxol, but the rate is very low. The maximum occurrence and high exploitation of Taxus has been reported from West Kameng district of Arunahal Pradesh, until the prohibition on its export through listing under Negative Lists of Exports by Government of India in 1996. Random linear transacts in the deep forests recorded a total of 145 Taxus plants. Out of which, 105 are dead trees and only 38 are live plants. Among the 38 live plants 20 are seedlings, 14 are saplings and 4 are full grown trees – one each near Sanglem and New Bomdila and another two between Ramda and Palizi. Therefore, conservation efforts like workshops, seminars, talks, distribution of pamphlets, pasting of posters and mass plantation has been organized by involving the villagers. The study attempts to explore the current status of Taxus in the aftermath of large scale trade occurred during 1990s and generate community awareness for conservation and regeneration of the important medicinal plant.
