TASVEG is a Tasmania-wide vegetation map produced by the Tasmanian Vegetation Monitoring and Mapping Program (TVMMP). TASVEG comprises 157 mapping units captured at a nominal scale of 1:25,000. TASVEG is continually revised and updated via photographic and satellite image interpretation and is verified in the field where possible. This version (4.0) represents the fourth major release of the TASVEG layer since 2004. TASVEG mapping is indicative only. Whilst extensive checks are applied to release versions of TASVEG, confirming the presence or otherwise of TASVEG communities requires field validation by a qualified practitioner.

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 species’ 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.

Data forms part of a project undertaken for the Resource and Conservation Assessment Council as part of the regional assessments of western New South Wales - Joint Vegetation Mapping Project (JVMP), Brigalow Belt South Bioregion (BBS). Murrurrundi 1:100K mapsheet was part of the "targeted API" program, whereby information on the structural characteristics and overstorey composition was obtained via aerial photo interpretation (API) of 1:50000 or 1:25000 aerial photography.; ; Joint Vegetation Mapping Project.
