These include the woylie, quenda, tammar wallaby, quokka, numbat and western ringtail possum. He was also the first European to see and describe the numbat. An adult numbat requires up to 20,000 termites each day. Some 20 species of native mammals, including the reintroduced numbat, have been recorded. Its closest living relative is either the Tasmanian devil or the numbat. The numbat first became known to Europeans in 1831. Since 2006, Project Numbat volunteers have helped to save the Numbat from extinction. The numbat is an emblem of Western Australia and protected by conservation programs.
