Increase in beach recession,
storm foredune damage and
dune instability.
Acceleration of calcarenite
cliff erosion.
Foredune damage could lead
to widespread dune destabilisation
and transport of
sand across dunes to
swamps lakes.
2030: Occasional storm tide
flooding above highest
known tides.
2070: Flooding will affect
both swamps and adjacent
low lying areas. At the 2m
inundation many
connections between
floodwaters occurs (Lidar
survey).
Frequent storm damage to
foredunes.
(Impacts uncertain. Existing
terrestrial vegetation is
found in warmer conditions
elsewhere)
Dune vegetation adapts to
drier conditions, but
recovers more slowly from
fire and storm damage
allowing weed colonisation,
notably exotic grasses: dune
mobilization becomes more
likely.
Reduced runoff and
increased evaporation
threatens seasonal lakes and
lakeshore habitats.
Drains and creeks may
increase sediment load to
coastal swamps and lakes
(this depends on land
management practices).
