The Nanum Wungthim Rangers deliver the Napranum Land and Sea Management Program on behalf of the Napranum Aboriginal Shire Council. 

The rangers care for the Napranum Deed of Grant in Trust (DOGIT), undertaking regular patrols throughout the area, recording and monitoring information of the country.

The rangers spend the majority of their time at the Pennefather River and Beach, due to the the high conservation value of the area. They also regularly patrol east to Billy’s Lagoon and south to an area known as 20 Mile.

The program is funded under the federal government's Working on Country Program, that is committed to land and natural resource management.

The Nanum Wungthim Ranger program have key responsibilities that include: recording and protecting cultural heritage; weed and feral animal control; visitor management; fire management; monitoring and  removal of ghost nets and  marine debris; protection and monitoring of nesting marine turtles; operation of marine turtle triage and rehabilitation facilities; and, community education.

As an added bonus, the ranger program hosts an annual marine studies group at Pennefather, where students from the Western Cape College focus on learning about marine debris, nesting turtles and ghost nets.  

The Nanum Wungthim Rangers are one of the founding member groups of the Western Cape Turtle Threat Abatement Alliance, playing a key role in reducing threats to vulnerable and endangered marine turtles nesting on the west coast of Cape York Peninsula.
