The Habitat Loss and Modification theme addresses the decline in condition and fragmentation of remnant vegetation and important habitats at varying levels. The program considers potential factors such as clearing, over-grazing, timber and flora harvesting, landscape fragmentation, fire regimes and salinity. It also recognises the need and importance for the development of baseline data and the involvement of stakeholders.
Riparian and wetland vegetation communities are particularly vulnerable to habitat loss and modification. In some circumstances, land management practices have resulted in the clearing of riparian and wetland vegetation and the degradation of these habitats by uncontrolled stock access. This has a direct impact on water, estuaries, coastal and marine assets.
Ongoing habitat loss and modification is partly due to a lack of adequate planning to address fragmentation of habitat, particularly on private land. Lack of knowledge or lack of capability to undertake appropriate property management planning may contribute. Where there is little recognition in landscape and property planning that vegetation provides crucial ecosystem services, land management conflicts can occur.
