Geodiversity values involve aspects of the abiotic environment
that are sometimes the dominant element that imparts scenic
and wilderness value, are scientifically important in their own right,
and almost invariably form the essential habitat for the biodiversity
that is often the main target of modern conservation policies.
Given this dominance of the physical landscape over other aspects
of wilderness character, the potential for restoration of degraded
wilderness depends foremost on the significance and resilience of
the landforms and the capacity for them to recover over an acceptable
time frame. The contradiction between the expectations that
wilderness is in pristine natural condition, should be available for
recreational use, yet is devoid of artificial intervention in natural
processes must also be addressed. This challenge looms increasingly
large in a world in which virtually all wilderness areas now face
anthropogenic climate change that is increasingly distorting natural
processes. This paper illustrates a geomorphological approach to
assessing wilderness restoration prospects by presenting a case
study of potential restoration of the original Lake Pedder, a scenic
glacial lake that was widely regarded as both the heart and crown
jewel of the Tasmanian wilderness prior to its inundation beneath
a large hydro-electric reservoir in the early 1970s. The applicability
of this approach to assessing potential wilderness restoration
endeavours elsewhere is discussed.
