Declared Weeds (points, lines and polygons) draws observation records from the Natural Values Atlas (NVA) of Tasmania of weeds that are listed as declared pests under the Biosecurity Act (2019). Understanding the distribution of weeds is integral to prioritising weed management activities and measuring outcomes of that work. The Natural Values Atlas (NVA) of Tasmania supports the administration of the Biosecurity Act (2019) through maintaining a centralised database that provides for secure and effective storage, retrieval and backup of weed data. Declared Weeds (Points), for any given species, is indicative only; it is a collection of observation records and not a definitive map of a speciesâ distribution or abundance. Potential data errors may include: inaccurate records (wrong ID/location), 'missing' records (not detected/reported), and 'historical' records (no longer present). Comprehensive, high quality data provides for better decision-making and relies on communal efforts to collect and share weed observations by submitting records to the NVA.
