The Forest Department in the year 1866 took over the forests of Buxa Tiger Reserve and prior to that these used to be an unoccupied wasteland. Those forests came under British rule in 1865 and the first reservations were made in 1879 according to the Indian Forest Act (Act VIII of 1878) and the process continued till 1940. Thus most of the forest areas of the Tiger Reserve enjoy the status of reserved forests under the provision of the Indian Forest Act (IFA), 1927 up to 1982. BTR was constituted in the Year 1983 in Jalpaiguri District vide Govt. of India’s notification No. J-11025/18/B/FRY (PT) dated, 16th February, 1983 and became the 15th Tiger Reserve of the Country.
