Geoconservation is an essential part of bioconservation, as geodiversity provides the variety of environments and environmental pressures which directly influence biodiversity.
Ongoing landforming processes, for example in cave (karst) and river (fluvial) systems, can easily be degraded by inappropriate disturbances in their water catchment areas. Old vegetated sand dunes can be 'blown out' following disturbance of their thin stabilising soil cover by vegetation clearing, vehicle use or fires. Peat soils can be entirely destroyed by a single bushfire. These examples are just the tip of the iceberg. Indeed, geoconservation often deals with relict or 'fossil' features which are not still forming, so that any degradation is permanent and unsustainable. There is a very good reason for active geoconservation management of such features, arguably greater than bioconservation where things can potentially be 're-grown'.
Thus, conserving the values and sustainability of natural environments requires full integration of geoconservation into broader nature conservation programs. However, historically most geoconservation work in Australia has been focussed on a "geological heritage" approach, in which geodiversity (under various names such as 'geological monuments', 'geological heritage' or 'significant geological features') was seen as being important mainly for its value to scientific research and education. Because this approach does not address issues of intrinsic values and ecological sustainability, the 'geological heritage' approach to geoconservation has largely been ignored or treated as a minor issue in nature conservation programs because of its percieved lack of relevance to central issues in land management.
For this reason, the principles and approaches which have been adopted by geoconservation workers in Tasmania are presented in some detail on this website in order to:
