The Tasmanian emu (Dromaius novaehollandiae diemenensis) is an extinct subspecies of the emu. It was found on Tasmania where it had become isolated during the Late Pleistocene. The Tasmanian emu was, as the mainland birds, hunted as a pest. In addition, the practice of setting fire to grassland and shrubland to aid in claiming land for agriculture deprived the birds of habitat. It is known that in 1838, two skin specimens were received by the British Museum. The subspecies became extinct around 1850, but this date is not very precise.
