3.5 Managing and Protecting Native
Vegetation and Fauna.
The condition of native vegetation remaining within the
Brockman River catchment varies greatly, ranging from
severely degraded to excellent with a diverse range of
species. Native understorey species are particularly
scarce due to grazing pressure. Several areas of excellent
vegetation lie within Public Open Space areas and
CALM reserves. Some remnants on private property are
also in good condition and a number of them are
permanently protected under covenant agreements.
The small size and isolation of remnant vegetation
blocks is of concern as this limits breeding success and
animal movement between remnants increasing the
likelihood of local species extinction. Endangered
species such as the Chuditch, Western Swamp Tortoise
and the Black Flanked Rock Wallaby have been
reintroduced into reserves within the Brockman River
catchment. The success of these translocations depends
on maintaining the native vegetation remaining and
creating linkages between patches.
Weeds and pest animals are also of concern not only for
nature conservation areas but also on private property
where they can reduce productivity for agricultural and
horticultural enterprises. The control and, if possible,
eradication of Patterson’s Curse, rabbits, feral cats and
foxes is seen by the community as most important in
protecting rural enterprise and nature conservation areas.
To protect and enhance natural biodiversity to
sustain ecological processes and conserve native
plants and animals.
In the Brockman River catchment;
• 51% of the original vegetation remains; a total of
• 26% of remaining vegetation is reserved, but this
• The native vegetation is located within a very large
number of remnants (1,521);
• 85% of the remnants are less than 10ha in size,
representing 5% of the native vegetation;
• 91% of the remnants are unreserved, representing
18% of the vegetation;
• 1 vegetation complex has less than 20% of its original
area remaining, while 12 complexes have less than
10% of their original area reserved.
Natural Resource Management Plan for the Brockman River Catchment
• No further loss of native vegetation.
10% increase in native vegetation through
remnants within 10 years.
• All public open space to have management plans
within 10 years.
• A fire management strategy that includes deliberate
use of fire for ecological regeneration as well as
hazard reduction and protection of property without
undue risk to native vegetation.
• Decrease in distribution and abundance of introduced
pests and diseases.
• Educate 80% of people to recognise weeds and
techniques for their control.
Strategies and actions
3.5.1 Assess and monitor the status of flora and fauna
in the catchment
• monitor the status and extent of remnant vegetation
throughout the Brockman River catchment
• identify flora and fauna in the Brockman River
catchment and develop community information
• review weed maps for the foreshore of the Brockman
River and roadside reserves to identify priority areas
for eradication and rehabilitation.
• protect and enhance roadside vegetation to reduce
loss of biodiversity
• protect existing and increase the number of “flora”
• educate the community about the value of riparian
• encourage the restoration of degraded remnants by
replanting to provide linkages and corridors between
remnants on private land, Nature Reserves and the
• provide advice and guidance on best plant species to
use in revegetation projects
• protect and enhance native vegetation areas and
encourage landholders to prepare vegetation
management plans in consultation with Land for
Wildlife officers for all remnants larger than 1 hectare
• promote covenanting schemes to protect remnant
native vegetation on private land
• ensure public access to areas where appropriate
recreational and tourist activities can be enjoyed by
the public is managed to minimise any disturbance on
the waterways and bushland areas
• encourage the development of woodlots as a
fuel/firewood source to reduce the pressure of
collection from areas of remnant vegetation.
• include fire management strategies in FESA and local
government fire management plans to minimize the
threat to natural vegetation that may result in potential
soil and nutrient loss, and encourage weed growth
• educate the community about bush fire risk and
encourage them to take responsibility for protecting
their own assets by managing fuel loads, installing
and maintain firebreaks, ensuring emergency water
supplies for fire fighting and ensuring emergency
• ensure that Local Government Authority plans
recognise that the deliberate use of fire for ecological
regeneration may require a different fire regime from
the current standard used by the bushfire brigades and
allowances need to be made for it in conservation
areas (including private land).
3.5.4 Control weeds and introduced pest animals
• identify priority environmental and agricultural
weeds and develop management plans for their
eradication or containment
• encourage landholders to eradicate and control pest
plants on their property, particularly the declared pest
• Increase awareness and education of landholders in
• eliminate feral animals from bushland along the river,
other bushland in the catchment and reserves, and to
control re-invasion with ongoing control programs
• consult with CALM to reduce excessive numbers of
kangaroos on private property
• provide information on baiting programs and
techniques to control feral animals
• encourage community participation in activities such
as Weedbuster Week to increase awareness of the
weeds present in the Brockman River catchment
• coordinate the weed control activities of Local
Government Authorities, State and Commonwealth
agencies, landholders and community groups
increase awareness of dog and cat
• Carry out biological surveys (see Actions 3.5.1).
• Fox control (see actions 3.5.4).

and where (see Actions 3.5.2).
• Weed control (see Actions 3.5.4).
• Enforcement of environmental remedial works
(see Actions 3.5.2).
4.1 The priority process
It is impossible to address all issues at the same time,
although different groups can carry out several actions
simultaneously. To determine the priorities amongst
many issues and actions in this management plan, the
following guidelines are proposed as a basis for making
High priority should go to high impact actions that;
• have many positive outcomes rather than few
(examples - fencing the waterways, revegetation of
high water recharge areas);
• ensure protection for the least degraded features in
the catchment (examples - streams that still
contribute fresh water to the river, least disturbed
and largest parcels of remnant vegetation), and;
• can involve and educate many members of the
community rather than few (example field days,
fostering community and “friends of” groups).
The difficulty in accomplishing the actions also needs to
be taken into account.
The actions listed in tables 8-11 have been prioritised
using the following method.
Figure 12: Method used to set priorities for actions.
4.2 Time frames
A time frame for each action in tables 8 to 11 has been
designated using the following criteria as a guide.
Short term. Actions that can be accomplished
Medium term. Actions that can be accomplished
Long term. Actions that may take 15 years or
Some actions will be on-going and these have been
designated as ML or SML.
4.3 Roles and responsibilities
Effective participation in managing natural resources
relies on developing an integrating process that involves
partnerships with the wider community and all levels of
government. This ensures that a balance between
economic, social and environmental values is achieved
within the Brockman River catchment. It is therefore
important to establish the roles and responsibilities of
the various stakeholders in this plan. It is also important
to ensure that this management plan links with the
players involved in regional and other local planning
strategies such as those listed in section 1.5.
Increased awareness of the catchment issues needs to be
developed within the community to ensure that
individuals are well informed. This will bring about a
change in attitude on how natural resources are used and
managed at all levels and encourage informed decision
Leaders can be identified who will encourage support
culture and achieving the objectives of the management
Landholders have an invaluable knowledge and
understanding of the issues involved in natural resource
management. Since management planning and actions
take place at the farm and paddock level, sustainable
natural resource management will only be achieved
through participation of landholders in the management
process and effective community ownership.
A number of community groups within the Brockman
River catchment are directly involved in natural resource

participation in natural resource management occurs.
Funding to carry out on-ground work is usually received
and managed through these groups.
• Lobby/write to local government and local
member re improving resources for catchment
management in the Brockman River catchment.
Highlight inefficient water use on inappropriate
land types to WRC (eg allocation of 10ML/ha to
grow lucerne on sandy soils. Could have been
achieved with lower allocation on heavier soil
type), Take issue to next level (ministerial) if
• Approach state government re interest subsidy to
farmers to enable management of landcare issues.
• Develop an incentive/ penalty scheme on shire
based environmental tax.
• Motivate and interest landholders.
4.3.4 Local government
Local Government Authorities can make decisions on
developments through their Town Planning Schemes and
adoption of policies that protect and enhance natural
Development proposals that do not undergo formal
environmental assessment by state agencies are dealt
with at the local government level. Public comment
through this planning process can contribute to
development that ensures sustainability.
Shire of Chittering should be encouraged to develop an
Environmental Management Plan and an Environmental
Advisory Committee similar to Shire of Mundaring and
CALM is responsible for biodiversity conservation
throughout the whole state, i.e. on all land tenures. They
issue licences for the taking of native flora and fauna and
provide detailed regulations for threatened flora and
fauna and ecological communities. They also provide
bushland management ands revegetation advice on
private property through the Land for Wildlife scheme.
A Conservation Covenant scheme is also operated
through CALM. Plant identification can be carried out
through the Community Herbarium program in the State
CALM is also a major manager in the catchment, as it
undertakes the day-to-day management of lands under
the care, control and management of the Conservation
Water and River Commission is responsible for the
management of all Western Australia’s surface and
groundwater resources. In the Brockman River
catchment this involves:
• Managing state water resources;
• Planning to ensure a balance between the water
requirements of the community and those of the
• Ensuring the protection of vital water resources, and;
• Conserving and restoring wetland ecosystems and
enhancing waterway environments.
The DEP is responsible for the protection of the
environment on behalf of the Minister for the
Environment. Management of the Brockman River
catchment can be influenced by:
• The Environmental Impact Assessment process
• Pollution licencing (Pollution Prevention); and
• Formulation of specific Environmental Protection
Policies (Policy Coordination)
The Department of Planning and Infrastructure provides
technical advice to the Western Australian Planning
Commission and the Minister of Planning and
Infrastructure. In catchment management, the
Department of Planning and Infrastructure has important
regulatory and supervisory roles in ensuring Town
Planning Schemes reflect the principles, actions and
policies of this Catchment Management Plan. It is,
therefore, most important that the Department of
Planning and Infrastructure is fully informed of the
issues affecting the Brockman River catchment and the
Department of Agriculture
The Department of Agriculture has an important role to
play in the management of the Brockman River
catchment through its agricultural production and the
The Department of Agriculture promotes the sustainable
development of farm business, agricultural business and
rural communities that are capable of meeting the
economic, ecological and social challenges in a rapidly
The landcare program supports the Land Conservation
District Committees within the catchment and focuses
on actions that achieve sustainable development and soil
The Swan Catchment Council is responsible for the
delivery of natural resource management within the
Swan region. The Brockman River catchment is part of
this region and future Commonwealth Government
funding will be directed through the council.
A Memorandum of Understanding has been signed
between the Avon and Swan Catchment Councils to
include the Brockman River catchment in the National
Action Plan for Salinity and Water Quality.
The Department of Defence has a management plan for
the Bindoon Training Area. As part of this area falls
within the Brockman River catchment it is important
that it is integrated with the catchment management plan
and addresses the issues raised.
Based upon community and land use boundaries the
Brockman River catchment can be divided into 5 distinct
zones for the purpose of natural resource management.
These zones are:
Zone 1: North - Wannamal. Mostly broad acre farms
growing cereals and canola, wool, sheep and cattle.
Zone 2: Central North - Mooliabeenie. Smaller farms
growing some cereal crops and grapes but mostly sheep
and cattle grazing, citrus and other fruit.
Zone 3: Central - Bindoon. This is the administrative
centre, main commercial and urban area of the
catchment surrounded by rural residential and citrus
orchards with some sheep and cattle grazing.
Zone 4: Central South - Chittering Valley. Mostly sheep
and cattle grazing and citrus orchards with vineyards
increasing rapidly. Areas of rural residential are adjacent
to the scenic valley.
Zone 5: South - Lower Chittering Valley. Enterprises are
mostly citrus orchards and vineyards, some sheep and
cattle grazing. A big demand for rural residential has
seen considerable subdivision in this area.
Working within these zones will make for easier and
more manageable groups to undertake community
Implementation of on-ground work has already begun
with many landholders undertaking work following
workshops to further discuss natural resource
management issues. Some of these projects have been
