Increased habitat fragmentation
When native vegetation is cleared, habitats which were once continuous are divided into separate fragments. These small fragments of remnant vegetation (patches) are isolated from one another by a mosaic of different vegetation and land uses. Barriers such as roads, powerlines and open agricultural land can restrict interaction of flora and fauna species within different patches. Patches are often small and can only support small populations of flora and fauna. Smaller populations are more vulnerable and local extinctions are not uncommon.
