Abstract |
Various vegetation Extent and Nativeness products, that include: the delineation by woody and non-woody; and maps of the uncertainty associated with assignment of extent and nativeness. The primary product is a NSW Native Vegetation Extent layer prepared for the National Land and Water Resources Audit 2008. This represents native vegetation extent at 2006. A number of other useful intermediate products are also available. Full report is available from http://maps.environment.nsw.gov.au ; ; VEGETATION EXTENT was derived from interim Foliage Projected Cover (FPC) data (FPC 00,02,04,06) prepared by the DECC's Woody Vegetation Change Detection Program in early 2008. FPC is generated from Statewide Landcover And Trees Study (SLATS) methodology, developed in Queensland by Qld Dept of Natural Resources and recently applied in NSW. The SLATS program applies a series of algorithms on Landsat TM data to produce FPC values ranging from 0-100 percent. A threshold (or thresholds) are applied to the FPC data to separate woody from non-woody vegetation. NATIVENESS was derived from interim NSW Land-use Mapping data (Emery et. al), and then used to ascertain whether vegetation may be native or non-native.; ; CAVEAT:Vegetation extent and nativeness layers generated for this project are interim in nature and are subject to ongoing refinement. While these products represent the best available estimate of vegetation extent and nativeness at this time they will be improved overtime and hence are not suitable for accurate reporting of vegetation change |

Update required due to errors detected in landuse data for Kosciuszko National Park, resulting in incorrect assignment of non-native to some areas. In addition, landuse data for ACT was acquired, enabling these data to be used to assign native or non-native values, instead of relying on Keith & Simpson (2006)data.; ; DECC (2008) NSW Interim Native Vegetation Extent (2008-Version 1) .

Lineage |
Extent was derived from an interim foliage projected cover (FPC) data based on 2000,02,04,06 Landsat TM epochs. FPC was prepared by DECC's Woody Vegetation Change Detection Program with assistance from Qld Dept of Natural Resources, using the SLATS methodology. Nativeness (native or non-native) was derived from draft Land-use mapping data provided by DECC's NSW Land-use Mapping Program (Emery et al.). It is intended that updated native vegetation extent products will be generated over the next 12mths. |

Explanation |
Woody and non-woody vegetation extent covers all of NSW. Native and exotic subclasses cover almost all of NSW, except for Sydney and other small areas where landuse data are currently unavailable.; ; Vegetation classifications are not finalised. Refinement of SLATS FPC and watermask data is continuing. The native/exotic subclasses may change as landuse information/interpretation is refined, and other potential data sources are examined. |

Explanation |
As the FPC values used in the derivation of woody/non-woody extent are essentially continuous data, the choice of an appropriate threshold is critical to maximise accuracy in a binary classification. This issue is complicated by the fact that an appropriate threshold for one part of the state (eg; eastern) is too conservative (regarding woody vegetation) in western areas. The threshold selected for this dataset version has erred on the conservative side for woody vegetation. An indication of the uncertainty regarding the woody/non-woody threshold is demonstrated in a parallel dataset which further categorises woody and non-woody classes into definite or probable sub-classes.; ; The accuracy of the native/exotic sub-classes is dependent on the accuracy of the landuse information and the interpretation of landuse classes. That is, each landuse class had to be assessed as to whether vegetation in that class would most likely be native or exotic. Some landuse classes were relatively easy to assess (eg; andquot;Native forest andquot;), whilst many were more difficult. As a general rule, landuse classes that could not be assessed as exotic were assigned a native sub-class. Therefore, the classification into native or exotic classes has erred in the favour of potential nativeness.; ; An accuracy assessment was carried out using 300 random points across NSW. The reference data for each point was derived from the visual interpretation of SPOT5 imagery. This assessment suggested an overall accuracy of 92.3 percent, with a Kappa co-efficient of 0.77869. |
