Drains and creeks may
increase sediment load to
coastal swamps, (this
depends on land
management practices).
The potential fall in
groundwater pressure a
significant threat to
vegetation survival in
freshwater swamps
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).
Maintain watching brief
on sedimentation of high
value swamps areas.
Adaptive management of
plant assets.
Monitor beaches, see
above.
Monitor salinity
of coastal
swamps.

Component Issue Proposed Action Priority of Key Players
Action
Beaches &
Dunes
Inappropriate ORV use
in the dunes and beaches
particularly at Jones Bay.
Vehicle use threatens
shorebird activity.
Restrict access to
nodal tracks.
Discourage access
along the coast. Fence
sensitive areas and
enforce compliance.
Reduce pressure on
habitat at shorebird
nesting times by a
seasonal vehicle ban.
Fence nests/
Community
monitoring.
Raising community
awareness through
signage at major beach
access points.
