Management level
|
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.
