NSW Weed Risk Management system
The New South Wales Weed Risk Management (WRM) system is a tool developed to assist weed managers in NSW to determine priorities for weed management at state, regional and local levels. The WRM system is used to evaluate noxious weed declarations in NSW.
The system uses a series of questions to arrive at a score for weed risk (invasiveness, impacts, potential distribution) and feasibility of coordinated control (control costs, persistence, current distribution). Once scores are determined, a table comparing the scores directs the assessor to what management priorities may be needed for the weed.
The NSW Weed Risk Management (WRM) system is based on the Australian and New Zealand Standard that is the National Post-Border Weed Risk Management Protocol. It was developed by NSW DPI in consultation with stakeholders to meet the needs of NSW weed managers.
