Abstract

Vegetation mapping of the northern part of Hawkesbury LGA. For more information see DECC (2008). This report describes the outcomes of a joint project between the Hawkesbury-Nepean Catchment Management Authority (HNCMA) and the NSW Department of Environment and Climate Change (DECC) to deliver a consistent and seamless vegetation map for the northern Hawkesbury Local Government Area (LGA). The project has been designed to provide the HNCMA and DECC with baseline data on vegetation communities to facilitate the implementation and reporting of biodiversity targets and objectives set out in the Hawkesbury-Nepean Catchment Management Plan. The major driver for this project was recognition that the study area was without consistent classification and mapping data that covered private lands and crown land tenures between the mapping available for the Cumberland Plain and the Yengo, Wollemi and Parr reserve systems. The study area covers around 28,000 hectares of land around the Hornsby Plateau in north-western Sydney. It encompasses the interface between the extensive shale deposits of the Cumberland Plain and the dissected sandstone plateaux. It is a zone that is undergoing rapid transformation in land use with rural holdings being transformed to hobby farms and urban subdivision expanding into rural-urban zones. VIS_ID 4167

Lineage

Two stages were undertaken as part of the data analysis. Firstly, all species abundance raw data from sites available from the study area was analysed using the PATN program (Belbin 1994). The Bray-Curtis coefficient was generated to identify dissimilarity between survey sites. An association matrix displaying dissimilarity scores between all pairs of sites was produced. An unweighted pair group arithmetic averaging (UPGMA) clustering strategy was applied to the matrix to derive a hierarchical classification. The default beta value of -0.1 was used on all analyses. Homogeneity analysis (Bedward et al., 1992) was initially used to identify the number of groups that maximises returns to within-group floristic variation while minimising the total number of groups. A nearest neighbour analysis using a purpose built program "GDFcheck" was applied to identify possible misclassified sites within groups. A dendrogram was then produced to display the hierarchical relationships between individual sites and groups of sites. Recent analysis carried out for the vegetation communities Yengo and Parr reserves (DECC, 2008) and the Cumberland Plain (NPWS, 2000) provided an initial guide to allocation of sites shared by these studies to vegetation communities present in the northern Hawkesbury LGA. Each of the defined groups were then analysed to uncover finer scale floristic assemblages where these related to changes in substrate or canopy species dominance. New groups were created where distinct changes in substrate, vegetation structure or canopy species dominance matched consistent patterns observed in the field. A second analysis, using the same methods, was performed on a larger dataset that comprised site data held by DECC within the greater Sydney Basin Region. The purpose of this analysis was to examine relationships between the vegetation communities present in the study area and other sandstone environments in the Sydney Basin Region (NPWS, 2000; Bell, 1998; NPWS 2003a; NPWS 2003b, DEC, 2006 draft). Provisional allocation of sites to vegetation communities from the first analysis was used to track site allocation in the second analysis. The second analysis was supplemented by labels identifying site allocation to vegetation communities described in studies listed above for Wollemi NP, Warragamba Special Area; Blue Mountains NP and the Woronora Plateau as well as broader regional community classification available in Tozer et al (2006). Mapping of vegetation communities was achieved by examining the level of congruence between the vegetation community described by the location of sample sites and mapped vegetation patterns (API codes) defined during aerial photographic interpretation. Utility of available mapping of substrate (soil or geology classes) was confounded by different attribution, classification and mapping detail across the St Albans 1:100 000 sheet (McInnes, 1997) and Penrith 1:100 000 sheet
