Global urbanization is proceeding at an alarming rate and is threatening the long-term survival of many important biological resources. Planners in the City of Durban (South Africa), cognizant of this impending environmental crisis, have designed an urban open-space network aimed at preserving a representative and functional example of the previous indigenous landscapes now under threat as a result of development.
Biogeographical principles have been used to produce for Durban a system characterized by maximized reserve size, continuity, and overall minimized system linearity with the lowest edge-to-area ratio possible. Emphasis has also been placed on economic viability and on the importance of community acceptance and participation within the system.
