The East Asian-Australian
Flyway Zone |
The main rice production areas in Australia are located on the Riverine
Plain of south–western NSW
and northern Victoria. The
plain's climate is characterised by hot dry summers and mild wet winters.
Biodiversity
Rice farms are homes for many types of plants and animals. The rice farmers
protect the biodiversity
of the region and maintain the ecosystems for the benefit of nature and
also to their farms.
Geography of the area - the earth
The plain is a landscape made up of riverine and aeolian sediment.
It is a gently sloping alluvial fan, tilting westwards from the major
river valleys in the eastern highlands. This plain is good for growing rice
because water must be able to flow evenly across the land so that it
reaches all of the rice plants.
The major soil types are clays, red brown earths and sand hill
soils. The soils are characteristically low in organic matter. The soil
is also relatively low in nitrogen, phosphorus and zinc, and therefore
suitable for agriculture.
Geography of the area - the plants
The natural
vegetation of the Riverine Plain ranges from sclerophyll forest,
dominated by eucalypts, in the eastern foothill section of the plain,
through to woodlands and scrub
steppe in the west. The change in vegetation parallels the decrease
in rainfall from the east to the west across the landscape. Visit the NSW
National Parks and Wildlife web site for more details.
Geography of the area - the
animals
The fauna of
the Riverine Plain reflects the diversity of habitats available.
Significant fauna known to occur in the
riverine forests of the Riverina Bioregion include the superb parrot
(Polytelis swainsoni), sugar glider (Petaurus breviceps), feathertail
glider (Acrobates pygmaeus), squirrel glider (Petaurus norfolcensis),
brush-tailed phascogale (Phascogale tapoatafa), koala (Phascolarctos
cinereus), carpet python (Morelia spilota), freckled duck (Stictonetta
naevosa) and peregrine falcon (Falco peregrinus)

Birds
The area comprises of about 100 species of birds, such as honey eaters,
flycatchers, thornbills, pigeons and parrots. In fact, the Riverina
rice region has become part of the East Asian-Australian Flyway Zone,
an international corridor for migratory journeys
of many bird species, including water birds that would not otherwise
be seen in this part of the world.
Mammals
Mammals include larger species such as kangaroos, bats and possums.
Reptiles
Reptiles include goannas, geckoes, dragons, skinks and snakes.
The rice bays and irrigation
channels are an ideal home for insects and animals including tortoises
and frogs. Research has shown that around 40 billion frogs are found
on rice farms throughout the Riverine
Plain and the endangered Southern
Bell Frog relies on the rice industry for its survival.
The Biodiversity
Strategy and Plan was developed by CSIRO
Sustainable Ecosystems
and the Rice Growers'
Association of Australia to provide practical guidelines for rice
farmers so that they can maintain and improve biodiversity. This ensures
that plants and animals can live productively with the rice growing environment. |
