Preventing and managing weeds in the NT

PREVENTING AND MANAGING WEEDS

Weeds are an increasing threat to the NT’s natural, economic and cultural assets. They compete with and often displace native species. They contribute to land degradation, loss of biodiversity and adversely impact agricultural activity. TNRM supports strategic and long-term approaches to weed management across the NT.

WORKING TOWARDS ERADICATION OF PRICKLY ACACIA FROM THE BARKLY

Weeds are a significant threat to the Barkly Tablelands region, where pastoralism is the dominant land use. A partnership has been developed to try and eradicate Prickly Acacia from the region in the near future.

FINNISS REYNOLDS CATCHMENT

The Finniss Reynolds Catchment Group (FRCG) project is a five-year project funded under the Australian Government’s Biodiversity Fund Round One initiative. The project is focused on controlling feral pigs and the invasive prickly floodplain weed, Mimosa pigra, across the high biodiversity value sites of the Finniss River and Anson Bay catchments, south-west of Darwin.

MANAGING NEEM TREES AT WICKHAM RIVER

This project contributed to the long-term eradication of Neem (Azadirachta indica) from the Heytesbery Cattle Company leased section of the Wickham River. This section of the river contained one of the largest known infestations of Neem along the Wickham. The project aimed to strategically manage this weed across 4,000 Ha of riparian habitat and associated flats that occur away from the river. Neem poses a significant threat to both primary productivity and biodiversity.
