Large tracts of the upper Tambo River's riparian zone is infested with Blue Periwinkle weeds. | For maps showing the current and potential distribution of some major invasive plants in Victoria - refer to Invasive Plants on the Statewide VRO website. Weeds have a serious impact on agricultural enterprises and various species are causing serious degradation of native vegetation and threatening the region's biodiversity values. Despite large commitments of time and money by private landholders and public land managers, weeds remain a major land management problem throughout the region. The Department of Sustainability and Environment (DSE) monitors infestations of priority weeds and records details, including the area and severity of infestation, in its Integrated Pest Management System (IPMS) database. Mapping and monitoring is undertaken on a continuous basis but is not complete for the region. |
