Garngi Land and Sea Management

The Garngi ranger group undertake work across approximately 110 000ha's of land and sea country at Croker Island and nearby mainland areas of cultural connection. Garngi rangers often work closely with the Mardbalk and Adjumarllarl ranger groups to restore the integrity of biodiversity in the northern sector of the internationally-significant Murganella flood-plain. Like most ranger groups they have an extensive weed management program in place to eradicate invasive and destructive species on the island including Mimosa pigra, Leucaena leucocephala (coffee bush) and Cenchrus sp. (mission grass.). The rangers have seen a successful reduction in Mimosa through ongoing seedling removal occurring around Minjilang floodplain. Animal management is also a core activity on the island, with many invasive and problem species causing havoc to environment and community dealt with through the ranger program; from continual training the rangers now relocate problem crocodiles, providing a sustainable solution to crocodile management. The rangers also monitor barge and barge ramps for cane toads; there have been no cane toads reported on Croker Island.
