Wagiman rangers undertake land management activities throughout the Wagiman Aboriginal Land Trust, which covers 130,000 hectares. Rangers have focused on treating extensive infestations of Gamba Grass (Andropogon gayanus), Mission Grass (Cenchrus sp.), Bellyache bush (Jatropha gossypiifolia), and Mimosa pigra. Work has been undertaken with collaboration with partners, such as the NT Weeds Branch, Territory NRM and the NLC Wardaman Rangers.
They have also undertaken a major fencing project of sacred sites to protect them against damage from feral pigs, buffalo, horses and cattle. The Wagiman Rangers are very active in engaging in cultural and Traditional Owner activities, including the new installation of the Tjuwaliyn arts project (Douglas Hot Springs).
