Stock Exclusion Low Slope Land LSL_2021proposed_NZ

The StockEx LSL 2021 proposed layer identifies proposed areas of "low slope land" where the Resource Management (Stock Exclusion) Regulations 2020 would apply if the low slope land map was updated as proposed in the "Stock exclusion regulations: Proposed changes to the low slope map" (MfE, 2021) discussion document. The layer shows the area of land defined as low slope land. These areas have a local mean slope is less than or equal to 5 degrees and are below 500m in altitude. Areas of lakes and ponds, estuarine open water, built-up areas, transport infrastructure, depleted grass, tall tussock grassland and urban parkland, as defined in Land Cover Database 5, are also excluded.

Statement

The general steps in the geo-processing methodology to create this dataset were as follows:

1. Starting with LCDB5, an exclusion layer of the built-up areas, open parkland, transport infrastructure, lakes and ponds, estuarine open water, depleted grassland and tall tussock grassland was created (LCDB5 exclusion layer).

2. An altitude exclusion layer was created by thresholding the Manaaki Whenua - Landcare Research 15m DEM to 500m (Altitude exclusion layer)

3. A slope layer was created from the MWLR DEM.

4. A focal filter was applied to the slope layer with a radius of 120m. This was thresholded to 5 degrees (Low Slope layer)

5. The LCDB5 exclusion layer and the Altitude exclusion layer were then erased from the Low Slope layer.

6. Finally small areas (less than 2 ha in size) and areas that don't intersect a REC river reach are removed to simplify the layer.
