Impacts and implications Protect and manage Address landscape
(for this cell) habitat threats issues: fire,
connectivity,
refuges, hydrology
Persistent swell wave climate
maintains sediment
movement towards the east
along the coast.
(Changes in upwelling timing
and frequency has been
discussed, but not
projected).
Monitor beaches (see

Table 6.4. Recommended Actions and Priority for Cell SE2 – Port MacDonnell
Component Issue Proposed Action Priority of Key Players
Action
Beaches,
dunes and
cobble ridges.
Coastal erosion causing
shoreline recession in
MacDonnell Bay.
Acceleration of sea level
rise due to climate
change threatens more
rapid future recession.
Off road vehicle use and
unleashed dogs threaten
shorebird activity.
Continue existing
beach profile record.
Establish new profiles
at Racecourse Bay and
Riddoch Bay
Aerial photography
analysis to determine
shoreline change.
Management as
required.
Reduce pressure on
habitat at shorebird
nesting times by a
seasonal vehicle ban
or seasonal detours.
Fence nests/
Community
monitoring.
Raising community
awareness through
signage at major beach
access points.
