Tasmania wetland recovers as invasive grass removal doubles fish species in 3 years
Tasmania's Duck Bay wetland is undergoing a significant ecological recovery following sustained efforts to eliminate invasive rice grass. Conservation group Circular Head Landcare reduced the weed's coverage from approximately 50 hectares to just five hectares. The removal of the invasive species allowed native saltmarsh vegetation to return to the area. Researchers from the University of Tasmania documented a rise in fish species from five to eleven, including the return of yellow-eye mullet. The findings highlight the effectiveness of targeted weed control in restoring coastal wetland biodiversity.
