Camp Creek Station recently had a massive gamba grass fire which showed up on the BOM radar. Owner Jeff Blake told us what happened and how he normally manages gamba grass:
Introduced to the Top End from Africa for pasture, Gamba Grass invades a range of ecosystems but is particularly damaging in the savannah woodlands. Gamba Grass grows to 4 metres in height and forms dense stands that burn at incredibly high intensity – up to 10 times higher than native grasses -destroying the woodlands and riparian vegetation, turning the once diverse landscapes into grassland monocultures. Wildfires are the NT’s biggest contribution to carbon emissions and Gamba fires are increasing this output every year.
