Aquilaria malaccensis Lam., a Red-listed and highly exploited tree species in the Assamese home garden

摘要

Natural populations of Aquilaria malaccensis Lam. are widely distributed in South and South East Asia. Actual accounts of the countries where it occurs vary. Oldfield et al. 1 have listed Bangladesh, Bhutan, India, Indonesia, Iran, Malaysia, Myanmar, Philippines, Singapore and Thailand as range states for this species. India is home to the following three Aquilaria spp., viz. A. khasiana, A. macrophylla and A. malaccensis. While A. macrophylla is restricted to the Nicobar Islands 2 , A. khasiana is limited to the Khasi Hills of Meghalaya 3 . A. malaccensis occurs mostly in the foothills of the northeastern region (Assam, Arunachal Pradesh, Nagaland, Meghalaya, Mizoram, Manipur, Tripura and Sikkim) and West Bengal 4 .
