In May, 2011, birders Ramki Sreenivasan, Bikram Grewal and Bano Haralu noticed Illegal tree-felling in primary lowland rainforest at Miao RF near Namdapha Tiger Reserve. There is serious loss of lowland evergreen forest in Miao RF and other neighboring RFs as well as inside Namdapha tiger reserve due to encroachments. A private elephant was dragging giant logs down the steep hillside and and deposited logs at a make-shift timber mill.
