Key Coastal Geomorphic Management Issues
Figure 3 Many coastlines in the NRM North and Cradle Coast region are moderate to steeply sloping hard-rock shores, such as that shown here north of Trial Harbour, western Tasmania. These shores tend to be highly robust and present few geomorphic management issues. However when these shores and their backshore areas are more or less undisturbed, they may have high conservation value for a variety of reasons including the importance of undisturbed geomorphic process systems, scenic values and in providing natural habitat for flora and fauna.
Figure 4 Shores of mixed sensitivity, such as the semi-lithified rocks and gravels intermixed with sandy substrates shown here at Doctors rocks south of Wynyard in northern Tasmania, are prone to progressive erosion, and may present a range of geomorphic management issues, particularly with sea level rise, even though they are less mobile than sandy beach shores.
