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. 

Objective 4

To protect and enhance natural biodiversity to

sustain ecological processes and conserve native

plants and animals.

Baseline knowledge

In the Brockman River catchment;

•  51% of the original vegetation remains; a total of

770 km


2

;

•  26% of remaining vegetation is reserved, but this



reservation is not comprehensive in terms of

vegetation types;

•   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

Targets

•   No further loss of native vegetation.

• 

 

10% increase in native vegetation through



revegetation, protection and enhancement of

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

sheets


•  establish a regional herbarium within the catchment

•  review weed maps for the foreshore of the Brockman

River and roadside reserves to identify priority areas

for eradication and rehabilitation.



3.5.2 Protect and restore native vegetation and

reduce loss of biodiversity

•  protect and enhance roadside vegetation to reduce

loss of biodiversity

•  protect existing and increase the number of “flora”

roads

•  educate the community about the value of riparian



and other bushland vegetation

•  encourage the restoration of degraded remnants by

replanting to provide linkages and corridors between

remnants on private land, Nature Reserves and the

riparian vegetation

•  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.



3.5.3 Develop appropriate fire management

strategies

•  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

vehicle access

•  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

plants

•  Increase awareness and education of landholders in



the best methods to carry out weed control

•  eliminate feral animals from bushland along the river,

other bushland in the catchment and reserves, and to

control re-invasion with ongoing control programs



3.10

Water and Rivers Commission

Natural Resource Management Plan for the Brockman River Catchment

•  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



control/management and enforce the appropriate

council bylaws.

(see Actions 3.5.2).



4.1

Water and Rivers Commission

Natural Resource Management Plan for the Brockman River Catchment

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

decisions.

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.

difficult to

accomplish

Priority 1

Priority 2

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.

S

Short term. Actions that can be accomplished



within 5 years.

M

Medium term. Actions that can be accomplished



within 10 years.

L

Long term. Actions that may take 15 years or



more to accomplish.

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. 

4.3.1 Individuals

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

making.

Leaders can be identified who will encourage support



and participation in developing a new community

culture and achieving the objectives of the management

plan.

4.3.2 Landholders

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.



4.3.3 Community groups

A number of community groups within the Brockman

River catchment are directly involved in natural resource

4. Making it happen



4.2

Water and Rivers Commission

Natural Resource Management Plan for the Brockman River Catchment

management and landcare. These groups include Land

Conservation District Committees and Catchment

groups.


It is through these groups that leadership, support and

participation in natural resource management occurs.

Funding to carry out on-ground work is usually received

and managed through these groups.



How the proposed actions respond to the

following suggestions from the Brockman

Catchment community forum:

• 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

required.

•  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

resources.

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

Toodyay.


4.3.5 State government agencies

CALM

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

Herbarium, Perth.

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

Commission.



Water and Rivers Commission (DEWCP)

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

natural environment;

•  Ensuring the protection of vital water resources, and;

•  Conserving and restoring wetland ecosystems and

enhancing waterway environments.



Department of Environmental Protection (DEWCP)

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

(Evaluation);

•  Pollution licencing (Pollution Prevention); and

•  Formulation of specific Environmental Protection

Policies (Policy Coordination)



Department of Planning and Infrastructure

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


4.3

Water and Rivers Commission

Natural Resource Management Plan for the Brockman River Catchment

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

management plan.

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

Landcare Program.

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

changing world.

The landcare program supports the Land Conservation

District Committees within the catchment and focuses

on actions that achieve sustainable development and soil

conservation.



4.3.6 Regional NRM groups

Swan Catchment Council

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. 



4.3.7 Commonwealth Government

Department of Defence

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.

4.4 Implementation 

4.4.1 Zones

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

actions.

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

reported in;

Torre, A. (2002) Demonstration sites of waterways

restoration in WA.  Water Note 27. Water and Rivers

Commission, Perth.
