Boonoo Boonoo National Park Vegetation 1999 2006 VIS ID 4716
공공데이터포털
Boonoo Boonoo National Park vegetation mapping was undertaken by Dr John T. Hunter in 1999 by contract for the NPWS Northern Tableland Region along with Bald Rock National Park. The mapping was revised in 2006. Boonoo Boonoo National Park is located approximately 30 km north east of Tenterfield. The vegetation of Boonoo Boonoo National Parks is described and mapped (scale 1:25 000). This forms part one of the survey of lands within these two reserves with part two of the survey incorporating newly acquired lands. Ten communities are defined based on PATN analysis and one specialised community is as circumscribed by previous surveys. These eleven communities are mapped based on ground truthing, air photo interpretation and altitude. Most communities are of a Tall Open Forest structure, however Woodlands exist along with Heaths, Sedgelands, Shrublands and Closed Forest. The distribution of communities is related to drainage, aspect, slope and soil depth. VIS_ID 4716

"Extant Native Vegetation of Boorowa Shire and surrounds.; Vegetation map based on classified vegetation survey data, and modelling layers, derived from a 25 metre Digital Elevation Model, and a composite geology map derived from Department of Minerals geology data. Data derived from the following sources: Digital elevation model in integer format, 25 m grid cells, produced 1997, Land Information Centre; Catchment variables derived from DEM, using Arcview 3.2; Geology data from 1:250 K Geology Map, Department of Mineral Resources of NSW; Derived Elevation, Slope Steepness, Drainage from DEM; Combined Geology and sub-catchments within Boorowa Shire; Derivation of individual grid layers for each map unit; Compilation of individual map units, using merge request function in Arcview 3.2; Derivation of vegetation mask, using Landsat ETM band 5 to create a native forest/woodland cover map; Intersection of pre-european vegetation map with M305 native woody vegetation map to produce extant layer.; ; Method used was based on expert modelling of vegetation types, based on consultant EcoGIS's (Nic Gellie) knowledge of distribution of similar vegetation types in relation to lithology and broad landscape variables. To reduce possible error in expert models, modelling zones based on a combination of lithology classes and sub-catchments were produced from expert examination of the spread and patterns of each vegetation group. The modelling zones helped to reduce the number of vegetation groups to be modelled down to 2-3 groups; Careful inspection of sites within each vegetation group helped to determine the broad environmental niche of each vegetation group. A table of possible relationships between vegetation groups and environmental variables was drawn up to help with the modelling process. It was clear that the patterns of vegetation in the study area were more influenced by geochemistry of the lithology classes and topographic position in the landscape, rather than the conventional aspect and moisture relationships found in coastal higher rainfall environments. This conclusion helped to determine the development of terrain variables that could separate vegetation groups that occurred predominantly on ridges and hillslopes from those vegetation groups that occurred in valley bottoms. A neighbourhood variable, using stream pattern derived from the watershed models within Arcview, helped to distinguish hillslopes from valley bottoms.; ; The modelling process enabled a complete audit of all vegetation types mapped in the study area and allowed a transparent and flexible process of mapping to be documented. In the event that detailed inspection of the results of the model or field validation resulted in possible changes to the map, individual modelling zones could be remodelled with the new knowledge, or new site data. This approach also prevented grid layers from spreading to areas where the vegetation groups would logically not occur in. When all modelling zones had been modelled, the resultant grid layers were then compiled into a single Arcview view. The data layers were then sorted into an agreed order of precedence that enabled each grid layer to be displayed on the final vegetation map. Reclassification and merge request functions within Arcview Spatial Analyst then produced a pre-European vegetation map. The final pre-European vegetation map was then masked with an extant vegetation cover to produce an extant vegetation map."; ; VIS_ID 1624; ; ANZLIC: ANZNS0208000217
Killarney State Conservation Area Vegetation Mapping. VIS ID 3992
공공데이터포털
Vegetation survey and mapping of Killarney State Conservation Area in 2008, commissioned by NPWS Narrabri Region. Six communities were determined based on floristic analysis of 20 x 20 m survey sites, and described using dominant species and structural characteristics. Vegetation communities were mapped using ground truthing, position in landscape and stereo interpretation of aerial photos captured at 1:50,000. Lineage and attribution accuracy are unknown.

Maryland National Park Vegetation 2006. VIS ID 4745
공공데이터포털
Maryland National Park vegetation mapping was undertaken by Dr John T. Hunter in 2006 by contract for the NPWS Northern Tableland Region. Maryland NP lies within NSW approximately 20km north east of Stanthorpe, Qld and comprises some 2,284 ha of lands. Parts of these reserved lands were once under the control and management of State Forests, while other more recent additions were free hold land used for grazing enterprises. The reserve lies along the NSW-Qld border and is half within the Northern Tablelands and half in the North Coast Botanical Divisions. The lands are incorporated entirely within the New England Tablelands Bioregion within the local government areas of the Parish of Marsh, County of Buller and Shire of Tenterfield. The vegetation of Maryland National Park is described and mapped (scale 1:25 000). Six communities are defined based on classification (Kulczynski association). These six communities were mapped based on ground truthing, air photo interpretation and landform. Almost all of the reserve is dominated by the Eucalyptus biturbinata, Eucalyptus campanulata and Lophostemon confertus. Much of the reserve has been disturbed in the past, particularly by Logging, clearing and grazing. The original mapping was recorded as VIS ID_457 and this version has the addition of PCT and fire veg classification fields. VIS_ID 4745
