The Crocodile River Reserve's project team set about identifyng a target area.
The ideal area for a Nature Reserve was informed by the Threatened Ecosystem listed in 2012 (earlier draft listings were used); on the National Protected Area Expansion Strategy (which placed large area adjoiing the Cradle of HUmankind as a "focus"), and the Conservation Plan of Gauteng (the C-Plan).
The Project has avoided crossing provincial boundaries in this first phase; already City of Johannesburg, Mogale City, the Cradle Management Authority and the City of Tshwane have a direct interest. Complicated enough!
The area in the West i.e. inside the Cradle of Humankind is following a different process, considering the role of an existing Management Authority and an International Agreement.
To the east, any property still intact, or significantly adjoining intact portions is viable.
The map below show the TARGET area within a green line. (Roads are show in orange and blue, with the provincial boundary in green)
