This dataset was superseded by the State Vegetation Type Map (https://datasets.seed.nsw.gov.au/dataset/nsw-state-vegetation-type-map) on 24.06.2022. Please note, Upper Hunter v1.0. VIS_ID 4894 web service and zipped dataset will be archived and will no longer be available on line after 31st March 2025. The NSW Office of Environment and Heritage (OEH) is producing a new map of the State’s native vegetation. This seamless map of NSW’s native vegetation types will enable government, industry and the community to better understand the composition and the relative significance of the native vegetation in their local area. The State Vegetation Type Map (SVTM) (http://www.environment.nsw.gov.au/vegetation/state-vegetation-type-map.htm) is constructed from the best available imagery, site survey records, and environmental information. The primary thematic layer in this dataset is a regional scale map of Plant Community Type (PCT) - "quickview" map. Where spatially coincident, this map of Upper Hunter (v1.0) supersedes the Greater Hunter Native Vegetation Mapping v4.0. VIS ID 3855 and was generated sourcing the following improvements: A comprehensive revision of vegetation plot allocation to Plant Community Types (PCT), superseding GHM v4 Map Units. Addition of 463 vegetation plots. Comprehensive revision of aerial photo interpretation of Vegetation Photo Patterns (VPP) at 1:10,000. A relevant selection of PCT’s were nested and modelled within each VPP. Utilisation of Boosted Regression Tree modelling in place of Generalised Dissimilarity Modelling All manual aerial photo interpretation of VPP’s modelled PCT’s performed using high resolution 50cm ADS-40 aerial imagery in place of SPOT-5 2.5m imagery. Semi-automated line work generated using high resolution 50cm ADS-40 aerial imagery in place of SPOT-5 2.5m imagery. Climatic and topographic rule based envelopes were generated to constrain the maximum spatial envelope for each PCT. Each envelope was further manually edited. Dry Sclerophyll communities further constrained by exposure and landform envelopes. Selective integration of the following pre-existing maps to PCT: VIS1849, VIS3863, VIS3913, VIS4184, VIS4778 312 vegetation communities mapped as PCT’s compared to 185 GHMv4 map units over this region. QuickView map fields: PCTID – Plant Community Type identifier. PCTName – Plant Community Type common names vegClass – The PCT’s Keith Class vegFormation – The PCT’s Keith Formation mapSource - The source of the polygon’s PCT attribution. MapName – The 100k sheet map name Note that this is a dissolved surface and does not highlight the fine internal line-work within each map unit. Please refer to the 100k full data sheets for the complete editable internal linework, which are available by request to Data.Broker@environment.nsw.gov.au. The data are provided in an ArcGIS 10.4 compatible file geodatabase. Fields in the undissolved 100k sheet fine scale linework: polygonID – Unique map polygon identifier PCTID – Plant Community Type identifier PCTName – Plant Community Type common name vegetationClass – The PCT’s Keith Class vegetationFormation – The PCT’s Keith Formation mapSource - The source of the polygon’s PCT attribution. Possible values are: Manual editing Site Survey Spatial Modelling Pre-existing mapping: VIS1849 Pre-existing mapping: VIS3863 Pre-existing mapping: VIS3913 Pre-existing mapping: VIS4184 Pre-existing mapping: VIS4778 Expert Rules (see note on grassland attribution below) PCTIDMod1 - The most likely Plant Community Type identifier as derived from the spatial model. PCTIDMod2 - The second most likely Plant Community Type identifier as derived from the spatial model. PCTIDMod3 - The third most likely Plant Community Type identifier as derived from the spatial model. vegStruct - Vegetation Photo Pattern (VPP) as derived from manual aerial photo interpretation of 50cm ADS40 imagery. Possible values for vegStruct include direct attribution of some PCT’s where possible in

"The NPWS were contracted by the Lower Hunter and Central Coast Regional Environment Management Strategy (LHCCREMS) to carry out vegetation survey and mapping across the region. The initial vegetation survey and mapping study formed the first major part of the data collection and analysis effort for this project.; ; The primary aims of the study were to ; produce a detailed cross tenure map of the distribution of the vascular plant communities in the Lower Hunter and Central Coast region; ; provide estimates of the distribution of the plant communities prior to the arrival of Europeans (pre-1750); ; utilise project methodologies which are consistent with the Comprehensive Regional Assessment (CRA) work conducted on public land in the region so that the two surveys can be amalgamated into a single database to greatly improve the resolution and usefulness of each; and provide a context for future studies so that data collection is compatible with, and contributes to the on-going development of a comprehensive regional database.; ; This work was then updated by Ecological in May 2003. This involved the integration of additional remnant mapping, review of mapping errors and correction, additional canopy cover mapping and other general refinements of the map layer, including information on canopy condition. Extant vegetation data mapped from aerial photos, combined with a pre1750 model of vegetation communities to produce an extant vegetation community map. Photos flown between 2000 & 2001 to produce extant vegetation map. This map then combined with the existing pre1750 vegetation community mapping undertaken by NSW NPWS to produce an extant vegetation community map."; ; VIS_ID 2225

Maitland City Council(MCC)Vegetation Mapping by Lisa Hill in 2003. Vegetation distribution map for lands within the extent of the local government area, excluding those contained within National Park or State Forest Reserves. Systematic vegetation survey was carried out in Maitland LGA to provide Maitland Council with detailed information on natural vegetation for strategic planning purposes. Flora was sampled at 55 field sites (plots) and extensive field reconnaissance was carried out across the LGA. Agglomerative cluster analysis of plot data delineated eleven vegetation communities and an additional two communities were described by previous work in the LGA work (NPWS 2000). A total of 8,305 ha of extant vegetation was mapped in Maitland LGA using aerial photograph interpretation (API) at 1:25,000 scale. This included thirteen vegetation communities and areas of scattered trees and regeneration that did not constitute intact communities. Much of the vegetation in the LGA has affiliation with vegetation in the central, lower and mid Hunter valley, with areas in the south-east of the LGA more related to coastal vegetation in the lower Hunter-Central Coast Region.
