Biological survey and reserve design by Landsat mapped ecoclines — a catastrophe theory approach

The hypothetical correlation between temporal and spatial patterning in Landsat data and temporal and spatial heterogeneity required by persistent small populations of animals vulnerable to extinction has been tested by a biological survey and then applied to the design of a biological reserve. Vulnerable animals were associated with gradual gradients (ecoclines) in multi-temporal texture transforms of Landsat imagery. Potential pest species and sites without fauna were associated with textureless areas and with abrupt boundaries. An area 150 000 km2 of the Tanami Desert in central Australia was mapped. The data were utilized to order biological reserve priorities.
