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
Barayamal National Park Vegetation 2008 VIS ID 4708
공공데이터포털
Barayamal National Park vegetation mapping was undertaken by Dr John T. Hunter in 2008 by contract for the NPWS Northern Tableland Region. Barayamal National Park incorporates approximately 178 ha and lies within the eastern outskirts of Inverell on the North Western Slopes Botanical District and the New England Bioregion. The vegetation of Barayamal National Park is described and mapped (scale 1:25 000). Five communities are defined based on classification (Kulczynski association). These six communities were mapped based on ground truthing, air photo interpretation and landform. Much of the reserve is characterised by Lespedeza juncea was the most ubiquitous species within the reserve. Overall the character of the vegetation within the reserve can be described as being dominated by herbs and grasses and in particular Lespedeza juncea, Themeda triandra, Dichanthium sericeum, Swainsona galegifolia, Sorghum leiocladum and Bothriochloa macra. All communities described are of conservation significance. VIS_ID 4708

"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
Kwiambal National Park Vegetation 2008 VIS ID 4742
공공데이터포털
Kwiambal National Park vegetation mapping was undertaken by Dr John T. Hunter in 2008 by contract for the NPWS Northern Tableland Region. This was a revision of the 1998 mapping. The Kwiambal National Park (6,517 ha in area) is approximately 130 km north-west of Glen Innes and 30 km from Ashford. Kwiambal is placed within one of the largest areas of remnant woodlands on the north west slopes of NSW. The region is in the Northern Complex Province of the Nandewar Biogeographical Region and within the North Western Slopes Botanical District, both of which are poorly represented in the current reserve network. The vegetation of Kwiambal National Park is described and mapped (scale 1:25 000). Eleven communities are defined based on classification (Kulczynski association). These Eleven communities were mapped based on ground truthing, air photo interpretation and landform. Much of the reserve is characterised by Callitris glaucophylla, Eucalyptus dealbata and Eucalyptus melanophloia in the overstorey with a shrub layer of Melichrus urceolatus, Leptospermum brevipes, and Acacia leiocalyx and a herbaceous layer of Aristida ramosa, Cheilanthes sieberi, Cheilanthes distans, Commelina cyanea, Tripogon loliiformis and Cyperus gracilis.
