Yugul Mangi Rangers work throughout the 670,000 hectares of land and sea country in the Roper-Gulf region. The rangers conduct river, beach, and sea patrols and undertake monitoring of sawfish and dugongs and of water quality and seagrasses along the coastline.
The Yugul Mangi Rangers are also busy on land conducting extensive dry season burning and controlling problem weeds such as mimosa, parkinsonia and rubber bush. They have worked with the Aboriginal Areas Protection Authority to record and manage significant cultural sites.
Other ranger activities include invasive species control, ghost net clearance, cultural support, environmental monitoring and compliance.
