The transitional NVR - category 2-vulnerable regulated land layer is a component of the transitional NVR map. The transitional NVR Map was prepared by Department of Planning and Environment (DPE) under Part 5A of the Local Land Services Act 2013 (LLS Act) and supporting Local Land Services Regulation 2014. Category 2-vulnerable regulated land for this layer is taken to include land designated as steep or highly erodible land, protected riparian land or special category land.
The 2021 annual review of the transitional NVR map was published on 26 March 2021. Please read below for details about changes occurring as a result of the 2021 annual review. The latest version of the map can be viewed online using the transitional NVR Map viewer.

The category 2-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)
Category 2-vulnerable regulated land is comprised of three layers. These being:
- Vulnerable 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.
Three datasets have been generated by creating buffers in the original dataset.
A 20-meter buffer was used for both sides of the bank to represent the no-clearing boundary within the banks of major streams, lakes and lagoons. The buffer polygon created includes the bed of the stream, lakes and lagoons.
A 22.5-meter buffer was applied on either side streams mapped by hydroline. It was assumed that the average stream width for a stream represented by a stream centre line is 5m.
For minor streams mapped by hydroline, a 10m buffer was applied either side of the stream.
Vulnerable - Steep Land, generated from 5m elevation data (courtesy Dept. Customer Service). This product has currently been generated for MGA Zones 54,55 only.
A slopes layer, generated from Shuttle Radar Topography Mission (SRTM) 30m >= 18-degree slope (https://datasets.seed.nsw.gov.au/dataset/srtm18). This product is included for MGA zone 56 only; and
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.
- Special Category Land. A selection of land susceptible to erosion or land that is otherwise environmentally sensitive, such as mass movement and salinity.
Changes to the mapping of category 2-vulnerable regulated land introduced in the publish of the revised transitional NVR Map on 26 March 2021 have resulted from the changes to the transitional NVR - land excluded from the LLS Act layer and also the refinement of the mapping of steep slopes land (>18 degrees slope). Availability of more detailed elevation data (5m ELVIS DEM) for New South Wales has resulted in changes for steep land mapping in central and western NSW.
The data is provided as multi value raster that identifies the category 2-vulnerable regulated land, category 2-sensitive regulated land and where category 2-sensitive and category 2-vulnerable regulated land overlaps.
Pixel values:
3 - category 2-vulnerable regulated land
4 - category 2-sensitive regulated land
6 - where category 2-sensitive and category 2-vulnerable regulated land overlap (display class)
Spatial datasets compiled in the category 2-vulnerable regulated land layer are sourced from Department Planning and Environment.
Data on the transitional NVR map viewer is updated on a monthly basis for minor data changes. https://www.lmbc.nsw.gov.au/Maps/index.html?viewer=NVRMap
