Our projects
The Bannister Creek Catchment Group are involved in many many projects,
both on ground and 'off ground'. Some of our current projects are
listed below. Click on the links or scroll down, to learn about
each project, see photographs and learn about how together we can
improve the health of catchments in the South East Region.
Living Stream
Site I
Living Stream Site II
Tom Bateman Wetland
Canvale Lake Restoration
Bannister Creek Reserve Restoration
All our projects are undertaken in partnerships with
other organisations such as the Cities of Canning, Melville and
Gosnells, the Department of Environment, Swan River Trust, Swan
Catchment Centre, SERCUL, Water Corporation, Australian Government
Envirofund, Swan Canning Cleanup Program and the Swan Alcoa Landcare
Program.
The catchment group is a community driven organisation
and we would love you to become involved in protecting and enhancing
your community. Please contact us to become involved in any way
you wish.

Living
Stream Part I
A "Living Stream" is a simple drain that has been converted
to a functioning ecosystem. The top section of Bannister Creek was
a straight, high walled channel that offered little to no environmental
or social values, but quickly and efficiently transported polluted
water straight into the Canning River. In 2000, the Bannister Creek
Catchment Group and the City of Canning undertook a major project
to give the creek a more natural shape with meanders, riffles, fringing
sedges, gentle sloping banks and thick vegetation on the banks.
The results a few years later: a more natural setting,
with habitat for a wide range of birds, the return of turtles to
the area, more controlled water flow and a system able to remove
nutrients and other pollutants from the water before it enters downstream
wetlands and the Canning River.
Living
Stream Part II
With the Living Stream Part I project well established, the Bannister
Creek Catchment Group and the City of Canning began earthworks on
a new project. This site was planned to create a slightly different
system, a 'transitional sedge habitat'. Rather than just having
gently sloping banks, the once steep edges were also terraced to
create a number of floodplains on the edge of the creek. The summer
water level will not be effected, however, different rainfall events
will flood a variety of sedge filled floodplains. This will not
only create great habitat but the views over these low lying plants
will improve the aesthetic values of the area.
The earthworks were completed in March 2004 and in
September the first sedges were planted. Already turtles were sighted
basking on the banks and a white faced heron seen feeding. The photographs
below show the changes in the first few months of the project.

Tom
Bateman Wetland
Tom Bateman Wetland is a constructed
wetland located by Nicholson Road next to Roe Highway. It collects
water from a large area, a majority of which is hard surface. As
a result problems including high water flows, erosion, sedimentation,
nutrient enrichment and pollution are very real. The wetland aims
to address these problems, while creating habitat and a place for
people to enjoy. Water entering the wetland flows through a series
of zones, before entering Bannister Creek and eventually flowing
into the Canning River.
The wetland has been built to direct the water to
flow through a series of deep and shallow water channels. This gives
the wetlands sedges time to remove some of the excess nutrients
from the system. This cleansing is done by the action of microbes
associated with the plants root system, the uptake of nutrients
for plant growth and through trapping nutrients in the sediment.
The wetland also plays an important role in regulating flash flows
in Bannister Creek. In a natural situation rainwater would slowly
flow as surface and ground water towards creeks or wetlands. The
land acts like a sponge, minimizing high flow rates. However, because
such a large amount of the catchment now has hard surfaces, rain
water moves far more quickly and in larger quantities. This causes
erosion downstream, as well as damaging infrastructure, such as
fences and bridges. The design of Tom Bateman Wetlands allows it
to take the role of a sponge, or a buffer, that manages flow downstream.
As a result Bannister Creek will see a reduction in flash flows
and the serious erosion/sedimentation process that unnaturally high
flows cause.
Tom Bateman Reserve and Wetland is also a great place
for people to visit. A dual use pathway offers an opportunity to
exercise in a relaxing natural setting. Or you can simply sit and
enjoy watching any number of the over 35 species of birds which
have been recorded using the area.
The construction of the Tom Bateman Wetlands has
been a partnership between many organisations including the City
of Gosnells, the Water Corporation, Urban Ecosystems, the Bannister
Creek Catchment Group Inc., Leighton’s contractors and Main
Roads Western Australia. Funding has also been provided by the Swan
Alcoa Landcare Program, Price Waterhouse Coopers and the Swan River
Trust - Nutrient Intervention Program.
Canvale
Lake Restoration Project
Canvale Lake, or the Wittenberg Compensating basin as it is also
known, is an artificial lake that collects water from some of the
Canning Vale industrial estate. The lake is part of a larger grassed
parkland owned by the City of Canning. The area that surrounds the
lake was often too damp for recreational use and so in 2002 the
City of Canning and the Bannister Creek Catchment Group decided
to return this damp land to its natural state. The area was segregated
using a low fence and in July 2003 over 4000 plants were planted
by members of the community and staff from the Challenge Bank (this
event was a Corporate Care Day organised in partnership with the
Swan River Trust). A variety of trees, shrubs and sedges were planted
and the use of pre-grown jute (a carpet like fabric with sedges
grown directly into it is laid on the soil and secured with pins)
was trialled. Though still in its infancy this project will increase
the habitat values of the lake and make it a haven for water birds.
Bannister
Creek Reserve Restoration
The Bannister Creek Reserve includes the areas of wetland and bushland
that are associated with Bannister Creek. They range from narrow
strips of sedges to complex wetlands and floodplains. Along this
area the City of Canning and the local community, including the
Bannister Creek Catchment Group, have been working hard to restore
this fantastic natural resource in the heart of an urban environment.
