The purpose of this study was: (1) to create maps of the distribution of vegetation communities in the Macquarie Marshes at decadal intervals, (2) to define trends in the condition of key vegetation communities, (3) to establish a series of vegetation plots within key vegetation communities for more detailed floristic survey and as a benchmark for trend analysis, and (4) to interpret the changing extent and condition of vegetation communities.
Note that there are 3 maps:
MacquarieMarshes_1991_E_4890
MacquarieMarshes_2008_E_4891
MacquarieMarshes_2013_E_4892
The 1991 map (VIS_ID 4890) and 2008 map (VIS_ID 4891) replace earlier versions (VIS_IDs 794 & 3920). These have been updated with the addition of fields (PCTID and PCTName) to align with the Vegetation map data standard Version 1.0 (https://www.environment.nsw.gov.au/research-and-publications/publications-search/bionet-vegetation-map-data-standard-version-1). PCTID was populated from the equivalent map fields. PCTName was populated from the Bionet Vegetation Classification Web Service (https://data.bionet.nsw.gov.au/). These fields were also added to the 2013 map, and populated the same way.
Note that no quantitative accuracy assessment was undertaken in preparing the maps. Map creation relied on expert knowledge of vegetation communities in the region. Refer to the mapping report* for further information on methods and limitations.
