Vulnerable Regulated Land layer is a component of the Native Vegetation Regulatory Map (NVR Map). NVR Map was prepared by Office of Environment and Heritage under Part 5A of the Local Land Services Act 2013 (LLS Act) and supporting Local Land Services Regulation 2014.
Vulnerable Regulated Land layer indicates where clearing of native vegetation may not be permitted under the Land Management (Native Vegetation) Code 2017, and a limited suite of allowable activities apply)
Vulnerable regulated land comprised of three layers. These being:
-
Riparian - generated from the NSW Hydroline and HydroArea dataset, natural named watercourses were used to capture streams with a buffer applied to both watercourses and water-bodies.
Two datasets have been generated by creating buffers in the original dataset. One 20-meter buffer was used for both sides of the bank to represent the no-clearing boundary within the banks of streams, lakes and lagoons. The buffer polygon created includes the bed of the stream, lakes and lagoons. The other 22.5-meter buffer was on either side of the single stream. It was assumed that the average stream width for a stream represented by a stream centre line is 5m.
-
Steep or highly erodible is a combination of data layers including vulnerable steep or highly erodible, which is generated from Topographic 3-dimensional 25 meters grid data derived from contour and drainage data sourced from the New South Wales Topographic Map Archive (pre1995), predominantly 10 meters and 20 meters contours used as source data and a Slopes layer (generated from Shuttle Radar Topography Mission (SRTM) 30m >= 18-degree slope).
-
Special category - a selection of land susceptible to erosion or land that is otherwise environmentally sensitive, such as mass movement and salinity.
