Figure: Distribution of permanent and semi-permanent waters on the White Cliffs 1:250 000 topographic map sheet before settlement (left) and at the present time (right). The solid and dashed circles in the top figure represent 10 km radii from permanent waters (including mound springs) and semi-permanent water holes, respectively. Only areas within the solid circles would have been permanently habitable for kangaroos. In the right figure red and green circles represent sheep grazing radii (5 km) from earth tanks (407) and bores and wells (155), respectively. Virtually all of the landscape is permanently accessible to both sheep and kangaroos.(After Hacker and McLeod 2003).
