This spatial dataset identifies land where development implications exist due to the presence of wetlands, as designated by the relevant NSW environmental planning instrument. The NSW Wetlands Policy promotes the sustainable conservation, management and use of the state’s wetlands Contact data.broker@environment.nsw.gov.au for a data package (shapefile)

The purpose of the Wetlands GIS of the Murray-Darling Basin project was to map the maximum extent of wetlands within a ten year period (1983-1993) based on the presence of water. Wetlands greater than 5ha were identified using a combination of an unsupervised classification of spectral classes of Landsat MSS imagery and ancillary wetland information to create information classes of broad wetland groups (Floodplain wetlands, freshwater lakes, saline lakes, and reservoirs). This data layer is the result of an external review of the Murray-Darling Basin Wetlands Verification Series 1.0. by relevant state agencies in NSW, Vic, Qld, SA and ACT.

The objective of this investigation was to respond to a request for regional assistance for a comprehensive delineation of wetland habitats subject to jurisdiction under Section 404 of the Clean Water Act and all wetlands subject to National Park Service (NPS) procedures for implementing Director’s Order #77–1: Wetland Protection within the floodplain of Blow-Me-Down-Creek upstream and within the immediate area surrounding Blow-Me-Down-Dam on Saint Gaudens National Historic Site (SAGA) lands. This work utilized the U.S Army Corps of Engineers (USACE) Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Northeast and Northcentral Region (January 2012) as the primary methodology for making wetland determinations in the field. A total of 3 palustrine wetlands encompassing 7.23 acres of land were identified and delineated from 22 -25 September 2014 within the study area (Fig. 1). Observed wetland habitats were primarily a combination of palustrine, emergent, persistent, habitats (PEM1) and scrub-shrub (PSS) habitats that exhibited extensive soil saturation at the time of the investigation. All of the identified and mapped palustrine wetland systems meet both the U.S. Army Corps of Engineers criteria and the Cowardin et al. (1979) definitions of wetland habitat. No new riverine wetland systems were identified and mapped over the course of this investigation.

An environmental classification developed in conjunction with the NSW Marine Parks Authority Research Committee. The purpose of the mapping was for use in assessments to identify potential locations for marine protected areas in NSW. For more information see: Breen D.A. and R.P. Avery. (2002). Broad-scale biodiversity assessment of the Manning Shelf marine bioregion. Draft final report for the NSW Marine Parks Authority. Copies of the report may be borrowed from the library: Environment Australia, GPO Box 787, Canberra ACT 2601 Australia This coverage is intended for used in regional level marine conservation assessment. It was prepared using very low cost techniques (ie. unrectified API) and should not be relied upon for navigation purposes. THIS DATA IS NOT SUITABLE FOR NAVIGATION PURPOSES. This represents an historic dataset providing transparency on the 2002 marine park systematic planning process. This product is one of three related datasets used in the assessment process: "NSW Ocean Ecosystems 2002", "NSW Estuarine Ecosystems 2002" & "NSW Marine Habitats 2002"
