SUMMARY
Lake Tyers UBF study area retains some significant stands of rainforest
including:
-
Limestone
Littoral Rainforest;
-
Bung Yarnda
Littoral Rainforest; and
-
Two Flora and Fauna Guarantee Act (1988)-listed floristic communities of
Warm Temperate Rainforest (once present, but now extinct in the UDF
study area):
-
Alluvial Terraces
Warm Temperate Rainforest; and
-
East Gippsland Coastal
Warm Temperate Rainforest.
-
Rare or threatened species including one Flora and Fauna Guarantee Act
listed species (Table 3):
-
Four rare or threatened plant species with many more likely to have
been present before clearing
-
Several nationally threatened and Environmental Protection and
Biodiversity Conservation Act (1999)-listed species (Table 4);
-
Swift Parrot and Grey-headed Flying Fox
All of the rainforests of the Lake Tyers UDF study area are threatened,
many provide habitat for both Environmental Protection and Biodiversity
Conservation Act (1999)-listed plants and Flora and Fauna Guarantee Act
(2988)-listed plants and animals.
Much of this rainforest estate has been cleared and all of the rainforest
vegetation is either listed as threatened under State’s Flora and Fauna
Guarantee Act (1988) (the Warm Temperate Rainforest floristic communities)
or is in the final stages of the nomination process (the Littoral
Rainforest floristic communities) under the Federal Environmental
Protection and Biodiversity and Conservation Act (1999).
The Council (and by extension the community that it represents) has
obligations under these acts of Parliament to conserve these threatened
rainforest communities as well as their threatened plants and animals.
Conservation and maintenance of these values requires rainforest
conservation both through the preservation of existing stands and the
rehabilitation and restoration of a significant proportion of the degraded
or previously cleared rainforest habitat in the UDF study area. If as a
community we choose to conserve and restore these rainforest habitats then
we have taken the biggest step towards conserving the cargo of rare and
threatened species they contain.
Fortunately there are significant synergies available across the UDF
study area between sensible planning overlays that deal with land not
suitable for development, erosion risk and storm water management and
nutrient processing whilst maintaining or restoring rainforests in Lake
Tyers area.
These synergies fall into the following groupings:
-
Marginal bluffs
occur along the lakeshore and the Ninety Mile Beach. These areas are
subject to landslip and tunnel erosion. This provides habitat to
Littoral Rainforest and should be left vegetated;
-
Storm water and nutrient processing along gully systems
through the conservation and restoration of listed Warm Temperate
Rainforest communities that have been locally proven to strip 70% of
floodwater phosphorous and 88% of ground water phosphorous (Peel in
prep. a).
Very
large and significant stands of native vegetation (mostly Littoral
Rainforests) have not been recorded from various plans in the UDF
document.
These omissions occur on the east facing marginal bluff of Lake Tyers
between Fishermans Landing Arm and Mill Point Arm.
The
significance of rainforests has been understated and important information
left out.
Conservation
status of rainforest in the Lake Tyers Urban Area
-
There are two ecological vegetation classes of rainforest present in the
study area (Warm Temperate Rainforest and Littoral Rainforest) with two
distinct floristic communities represented (Table 1.). The UDF does not
identify rainforest as a significant feature of the area study
The UDF fails to list the following: the floristic communities (Table 1),
their conservation status and the threats to them (Table 2) and their
threatened species [Table 3 (plants) and Table 4 (animals)] and rainforest
depletion by locality (Table 5).
Rainforest
values to the environment and the community at large
In
Victoria rainforests conserve 4% of the states plant diversity (30% of
which are rare and threatened species), despite occupying less than 0.14%
of the State’s land area.
-
Rainforests are excellent water processors and have been proven locally
to strip up to 70% of the phosphorous from surface storm water and 88%
from ground water. This works best in streams of up to third order
(which matches all of the stream orders of the gully systems in the UDF
study area);
-
Rainforests are fire retardant and so their presence in the urban
environment is a benefit in this regard;
-
Rainforests consist of species that are restricted in the landscape that
can only be conserved by protecting rainforests and their fringing
ecotones;
-
Rainforest on or adjacent to properties is a major selling point for
real estate; and
-
Rainforests enable urban kids to experience the bush with relative
safety near to home.
Constraints imposed by the conservation status of rainforest
All of the Warm Temperate Rainforest and Littoral Rainforest communities
of East Gippsland are protected by the NVP regulations. All of the Warm
Temperate Rainforest and Littoral Rainforest floristic communities within
the Lake Tyers urban area are threatened. None of the rainforests in the
UDF area will survive without concerted local government and community
actions that include zoning to protect existing rainforest remnants and
their ecotones and zoning to conserve currently cleared habitat to ensure
planning and subsequent development allow recovery of the rainforests in
their past habitat.
Benefits
of conserving existing stands of rainforest and the currently cleared
habitat of rainforest
The following benefits will accrue if the council adopts planning measures
to conserve these areas of the landscape:
-
High tunnel and gully erosion-risk areas will be protected and erosion
risks to infrastructure and housing will be reduced;
-
Obligations under the Federal Environmental Protection and Biodiversity
Conservation Act (1999) and State Flora and Fauna Guarantee Act (1999)
will be met;
-
Nationally and State-listed rainforest vegetation as well as their cargo
of rare and threatened plants and animals will be conserved;
-
Storm water treatment is facilitated by the restoration of rainforests
to gully systems in the Lake Tyers UDF study area;
-
Nutrient stripping (particularly phosphorous) will remove up to 70% of
phosphorous and if combined with the reinstatement of wetlands at the
mouths of rainforest gullies nitrogen sequestration is enhanced as well;
-
Urban and landscape amenity is improved and the environment is
conserved.
