Since European settlement, the impact of vegetation clearance,
introduced plants and animals and unnatural fire regimes, have resulted
in the fragmentation and degradation of ecosystems across South
Australia. This led to a decline in populations of many species
of wildlife (plants and animals) in the State. Some have become
extinct with many others now considered to be in danger of becoming
extinct. Introduced diseases like the root rot fungus Phytophthora,
illegal collecting and hunting and fishing also adversely affect
some species.
In South Australia, threatened species are listed and protected under
the National
Parks and Wildlife Act 1972.
The threatened species schedules are continually under review.
The most recent revision of the threatened species schedules was gazetted
in February 2008:
There are five essential threatened species conservation elements:
Research and Planning
Conservation programs must have an active and strategic link between the
habitat or species being managed and the actions being carried
out. Whether its the monitoring of Yellow-footed
Rock-wallaby populations or genetic studies of Black-eared
Miner colonies, research allows the outcomes of these programs
to be assessed. These procedures are incorporated into programs
in a process known as Adaptive Management. Conservation
programs are designed to contribute to the learning process,
resulting in proactive rather than reactive management. Successful
Adaptive Management relies on good planning (ie defining the
problem), establishing clear objectives for recovery plans,
determining time-frames and identifying criteria for measuring
the success of these projects.

Effective recovery and protection requires the removal of threats such
as vegetation clearance, feral animals and degradation of water
systems. The Glossy Black-Cockatoo
may benefit from restoration and reestablishment of its feeding
habitat (drooping sheoaks), but its individual nesting trees
must be identified with the prevention of predators from preying on fledglings.
Operation
Bounceback, an example of an ecological restoration
program being carried out in the Flinders
Ranges National Park, has capitalised on the release of
the rabbit calicivirus disease, which has significantly reduced
rabbit populations in the Flinders Ranges. This control method
has been augmented by destruction of rabbit warrens in the park,
and grazing pressure being further reduced by goat control,
resulting in increased regeneration and vegetation survival.
Active revegetation or implementations of pest control programs
allow habitats to recover naturally. In the case of the Flinders
Ranges, reclamation techniques may be used to prevent erosion in
susceptible soils, increase filtration of water into the soil and
provide a sheltered bed for the germination of seeds. In many cases,
natural recovery is possible, although it can be a lengthy process.
Landowners, community groups and local and state Government agencies
can all work towards the recovery of habitats. One such example
is the Silky Tea-tree and Cutting
Grass Wetlands project (350Kb PDF),
run in the South-East to protect these rare wetlands.
By removing threats and restoring habitats, population sizes will
often increase. Results of habitat monitoring may also indicate
that reintroducing species into areas they previously occupied is
possible. A number of successful reintroduction programs have been
carried out in South Australia, including Brush-tailed
Bettongs at Venus Bay on the Eyre Peninsula and Stick-nest
Rats on Reevesby and St Peter Islands. Reintroduction programs
are currently being implemented for Bilbies
(Thistle Island in the Spencer Gulf, Arid Recovery [Roxby Downs],
and Venus Bay) and Stick-nest Rats
(Arid Recovery).
Investment in biodiversity conservation (money, materials or time),
should have a long term commitment. Projects must address long term
recovery to ensure that populations of threatened species can eventually be viable
with little or no external intervention. Community support and participation
are essential for every element of threatened species conservation,
for achieving recovery and retaining these gains well into the future.

Threatened Flora of South Australia
There are over 300 plant species in South Australia that are listed
as threatened (endangered or vulnerable) under Commonwealth and
or State legislation. These species are at risk of becoming extinct
in the wild if no actions are taken to secure their survival. Recovery
programs for many of these species are being implemented by Department for Environment and Heritage
in partnership with other organisations, community groups and land
holders.
Recovery Plans
Recovery plans have been prepared for many of South Australia's
threatened species. These plans contain information about the distribution,
abundance, biology, ecology and habitat of threatened species. Importantly
these recovery plans also outline the threats to each species, and
prescribe recovery objectives and actions to improve their conservation
status.

Fact Sheets
As part of the recovery programs, fact sheets are being produced
with the aim of raising awareness of the need to conserve these
species in the wild. The fact sheets provide information that will
help people to identify the species and understand the processes
threatening their survival.

Whales
Whales have captivated generations of us - their unusual behaviour,
appearance and immense size is of interest to people from all
around the world. Each winter the South Australian coast is
visited by Southern Right Whales and it is our aim to enhance
your experience with whales while ensuring that both the whales
and our coast are protected.
Take a look at our Whales website.
