Management
problems in small remnant patches are due to external influences eg weed invasion,
grazing by livestock, microclimatic, and hydrological changes.
It is difficult to control nutrient and water flows, for example, salination present in parts of the wheatbelt could be due to management further up the catchment. This means that there is a need for complex management to address landscape level problems
The management
of spatially structured populations should take into account overall landscape
pattern in determining populations dynamics rather than just the characteristics
of individual habitat patches (Forman,
1995). Models suggest that the persistence of metapopulations
depends on landscape pattern.
This means that research needs to look at the response of populations to entire landscapes. To only look at individual patches gives only half a story. This re-emphasises the need to take a holistic approach to land management that covers large areas and underpins the need for technologies such as Geographic Information Systems and Remote Sensing.
