The Tasmanian Reserve Estate dataset is a digital map of the Reserve System for Tasmania. It represents land reserved to be managed for biodiversity conservation under Tasmania's Regional Forest Agreement (RFA) and other instruments. The layer combines data from several sources: - LIST Public Land Classification [ANZTA0005000047] - Wellington Park - LIST Private Reserves [ANZTA0005000004] - Protection Zones from Sustainable Timber Tasmania's 1:25 000 Management Decision Classification (MDC) series - Land purchased by Private Land Conservation Program (PLCP) for conservation of CAR values not yet proclaimed - Indigenous Protected Areas - Informal Reserves on public land identified during the Regional Forestry Agreement (RFA) - Other private reserves that have been set aside under independently certified forest management systems - Future Potential Production Forest - Stewardship Agreements - Roadside Conservation Sites More information available in Business Rules at https://nre.tas.gov.au/conservation/development-planning-conservation-assessment/planning-tools/tasmanian-reserve-estate-spatial-layer

The Tasmanian Reserve Estate dataset is made up of data from the various data sources through the application of business rules, which are available in a more detailed document. Only reserves that were effective as at the nominated date (30th June, 2019) are included. Because the constituent data layers are of different spatial accuracy, they were combined in such a way that layers sourced from the LIST were given priority. That is, where overlaps occurred, the attributes from the LIST layers were used. The resulting reserves layer was overlaid with the mean high water mark, to determine which reserves are terrestrial, and which are marine. Some reserves were split to show the portion that is marine, and the portion that is terrestrial. The terrestrial portion of reserves includes offshore islands and inland waters but excludes estuaries.

Position Accuracy: The positional accuracy of the Tasmanian Reserve Estate varies depending on the source of the data. Refer to the positional accuracy for those layers where metadata is available already: LIST Public Land Classification, LIST Private Reserves. The positional accuracy of the Protection Zones from Sustainable Timber Tasmania's 1:25 000 Management Decision Classification (MDC) series is known to differ from the underlying LIST Cadastral Parcels layer for the same features. The differences in accuracy and location of boundaries have resulted in a large number of small gaps and slivers in the layer. The layer currently has many slivers resulting from the slight mismatch between Future Potential Production Forest and other input layers. These will be resolved over time as boundaries and land classifications change. The positional accuracy of the boundaries of the final Tasmanian Reserve Estate dataset should not be inferred as being better than +/- 50 metres. The dataset is broadly suitable for depiction at a mapping scale of 1:50,000. Thus the layer should be used for its main purpose of reporting, not for defining the tenure of a specific location on the ground. Attribute Accuracy: Attributes have been assigned through the use of the business rules and from what has been provided with the source data and extracted from other text databases. A lookup table was developed to populate many of the attributes. Where the value of an attribute is unknown, it is left blank, or has a value of Unknown. At times the specific reserve to which a value was to be attributed was difficult to identify, particularly for those reserves with unproclaimed names, such as covenants. Logical Consistency: Data has been quality assured by the Environment Business Unit of NRE Tas, Land Tasmania, and Sustainable Timber Tasmania. The data has been checked against component datasets and has no overlaps. Completeness: The data covers all known Formal, Informal and Private Tasmanian Reserve Estate in Tasmania. Values managed by prescription are not spatially recorded and have not been included. The date of currency of each input layer is identified in the As-At Date field. The data is suited for use as a statewide overview, for reporting purposes and for determining reservation status. Tasks requiring a more current layer, or precise boundaries should use the live datasets that are available on the LIST.
