Details are as follows:

1. Gourits River

The boundary begins at the coast, incorporating the mouth of the Gourits River, and continues northwards towards the Langeberg following the course of the Gourits River and its associated Gouritz Valley Thicket vegetation (STEP). The boundary is wider than expected in places, owing to the size and shape of properties along the river course. The MS then traverses the Langeberg along the Gourits River through the valley west of the Cloetes Pass and proceeds north to capture the confluence of the Groot and Gourits Rivers. It then tracks the Gourits River valley, through Calitzdorp, and northwards towards the valley between the Klein and Groot Swartberg and Die Poort. It then branches out to incorporate the courses of the Dwyka and Gamka Rivers, ending at the northern boundary of the planning domain.

2. Western Little Karoo

The boundary is defined by the planning domain in the north and west, and by the Gourits River MS in the east. Its southern boundary is defined by the Western Coastal MS (see below). It thus incorporates the Klein Swartberg in the north and the Little Karoo, but not the Langeberg in the south.

 
3. Eastern Little Karoo

The boundary is defined by the planning domain in the north and east, and by the Gourits River MS in the west. Its southern boundary is defined by the Eastern Coastal MS (see below). It thus incorporates the Groot Swartberg in the north and the Little Karoo, but not the Outeniquas in the south.

4. Western Coastal

The northwestern boundary begins at the western edge of the planning domain and incorporates the Koo Langeberg Mountain Fynbos Complex (CAPE) to the west of Montagu (Die Koo Mountains). The boundary then follows the Southern Langeberg Mountain Fynbos Complex (CAPE), passing to the south of Barrydale, and extending eastwards towards the Gourits River MS, all along the northern foothills of the Langeberg Mountains. This MS thus incorporates the Langeberg in the north and the entire coastal plain to the coastline.

5. Eastern Coastal

The northern boundary begins at the eastern edge of the Gourits River MS, and continues eastwards following the northern border of the Outeniqua Mountain Fynbos Complex (STEP). It then follows the Kouga Mountain Fynbos Complex (STEP) just south of Uniondale, and continues along the Baviaanskloof Mountain Fynbos Complex towards the eastern boundary of the planning domain and the Baviaanskloof Wilderness Area. This MS thus incorporates the mountain ridges (the Outeniqua Mountains, and some of the Kougaberge and Langkloofberge) that define the southern end of the planning domain in this region (it does not incorporate the Garden Route coastal plain to the south).
