Aquilaria malaccensis Lam. popularly known as Sanchi or Agaru in Assamese is a tropical forest tree with great economic value. Because of the indiscriminate harvesting from natural forests, the species is included in Appendix II of CITES to bring the international trade under sustainable level. The species is Vulnerable worldwide, Critically Endangered in India and almost Extinct in Wild in Assam. There are two distinct morphs of A. malaccensis viz. Jati Sanchi and Bhola Sanchi cultivated in Assamese homegardens. An attempt has been made to study the population status of both the variants in 37 randomly selected homegardens of Golaghat and Jorhat districts of Assam. It was studied by quadrat method and were grouped into seedling (≤20cm height), sapling (>20cm height and ≤30cm GBH) and tree (>30cm GBH) for analyses of population status. Since the individuals of seedling and sapling encountered in the homegardes for both the variant could not be identified, it has been grouped together for both the variant. Population density (individuals ha -1 ) of trees of Jati Sanchi and Bhula Sanchi was 430 and 8 respectively, it was 6,916 for saplings and 25,568 for seedlings. Tree density (individuals ha -1 ) of both Jati Sanchi and Bhula Sanchi varied among different homegardens and ranged from 33 to 1263 (mean 445?56) for Jati Sanchi and 0 to 150 (mean 8?4) for Bhula Sanchi. Overall study showed good regeneration status (seedling>sapling>tree) of A. malaccensis in homegardens of upper Assam. As a result of small scale cultivation in homegardens, population has been increased by many folds thereby helps in conservation of a species from the verge of extinction
