Component Issue Proposed Action Priority of Key Players
Action
Beaches and
dunes
Weeds
Pest animals
ORV activity remains
high, with threats to
vegetation, dune stability
shorebird nesting and
heritage sites. Activity is
incompatible with the
objects of Canunda NP.
Alteration to dune and
regional water tables due
to climate change.
High conservation value
habitat for the
endangered Orangebellied
Parrot focal
species.
Aggressive weeds
recorded at isolated
locations in the dunes
along the length of the
cell.
Rabbit populations are
recorded as high for the
northern half of this cell,
threatening coastal
biodiversity.
Review access policy
and trails; consider
seasonal beach driving
ban/ zoning to
protect shorebirds.
Monitor habitat
conditions in perched
and back barrier lakes.
Protection of existing
habitat and efforts to
reduce disturbances.
Eradication should be
considered for those
with limited
distribution at present.
Regular monitoring
for alert weeds, listed
in Section 4.9.
Undertake rabbit
control.
