Wetlands and Catchments of Conservation Value Decision Guidelines

1 Introduction

The Hindmarsh Shire contains numerous low-lying areas that hold wetland conservation values. These conservation values indicate areas that may be of ecological significance. The ecological condition of these wetlands has the potential to be degraded by the impact of land use and development. The Wimmera Catchment Management Authority has undertaken investigations that seek to identify the location of a range of conservation values of various wetlands.

Table 1, in Appendix one identifies each wetland with an individual wetland number and shows its size and descriptions of the wetland hydrology classification (described by using the Corrick Classification) and conservation values present.

Wetland hydrology (Corrick Classification) is classified based on the depth, duration of inundation and the nature of the water (fresh or saline). Wetlands are divided into 6 broad groups as outline below (Table 1). The vegetation community that a wetland supports provides the habitat structure that supports the fauna that utilize the wetland.

Wetland hydrology classification and data, are key to understanding if the wetland warrants management consideration and how to make management responses to use and development applications.

Each of these wetlands of conservation value has the potential to receive water from the primary catchment areas identified in ESO 6, as defined by the topography of the landscape. It is important that land use and development within these catchments does not impact on the ecological condition of the wetlands of conservation value.

These Decision Guidelines are intended to be used for deciding on planning permit applications for land covered by both Environmental Significance Overlay 5 (ESO 5) and Environmental Significance Overlay 6 (ESO 6). The process for making a decision will be slightly different for both ESO 5 and ESO 6, as the management objectives are different for both areas.

The Wetlands and Catchments of Conservation Value, Local Planning Policy seeks to identify land use issues which should be addressed when a Planning Permit for use is required for land identified in either ESO 5 or ESO 6.

ESO 5 only applies to wetlands that have conservation values, and as such it seeks to preserve the ecological condition of those areas by managing development in the wetland itself. ESO 6 only applies to the catchment area that surrounds the wetland of conservation value, and seeks to ensure that water leaving the catchment and entering the wetland of conservation value does not alter the ecological condition of the wetland of conservation value.

2 Conservation Values of Wetlands

The wetlands listed in table 1 Appendix 1 were determined to be of conservation value based on a range of attributes. As such, these areas warrant attention, as they may be of ecological value. Each of these attributes relates to an Environmental Objective to be achieved via the implementation of the Wetlands and Catchments of Conservation Value Local Planning Policy and Environmental Significance Overlays 5 and 6. The significance of these attributes is discussed below.

2.1 Depleted wetland type since 1994 mapping

Wetland surveys were started in Victoria in 1975 by Norman and Corrick their methodology has become known as the Corrick Classification System. The Norman and Corrick (1994)) classification system, (referred to as the Corrick (1994) system hereafter) is the State based wetland mapping system, which has mapped all wetlands 1 ha, or greater and classified them into one of eight categories based on hydrology and salinity. In 2004 Wimmera CMA updated the Corrick mapping using updated and more advanced data sets. Analysis of the Corrick (1994) and the Wimmera CMA (2004) wetlands mapping layer identifies Freshwater Meadows and Deep Freshwater Marshes as depleted wetland types (in area and number) across the Wimmera, these wetland types are also the most productive and biodiverse groups.

Depleted wetland types require protection to ensure that the diversity of wetland habitats is maintained and biodiversity protected.

2.2 High Level of Naturalness

Wimmera CMA (2004) wetlands mapping identifies modification within the wetlands, such as the presence of drains, dams and banks. Wetlands that have undergone lower levels of modification have the potential to have a more natural hydrology regime, therefore higher level of ecological functionality. This value also includes an element of

Page 6 8/08/2008

visual amenity, in that the level of naturalness is a consideration in the design of man made structures.

2.3 Wildlife Conservation Reserve

Land identified as a Wildlife Conservation Reserve by the Land Conservation Reserves, Melbourne (1981). These wetlands were reserved as they provided specialized habitat for large groups of birds, fish and crustaceans and some mammals. Some may contain habitat for endangered species and have ecological significance (LCC, 1981).

2.4 Threatened Wetland Flora

Threatened flora is identified by under the Flora and Fauna Guarantee Act (1988). This Act contains a number of conservation and management objectives as well as Action Statements for threatened flora. These objectives and Action Statements must be met by any proposal for use and development.

2.5 Threatened Wetland Fauna

Threatened flora is identified by under the Flora and Fauna Guarantee Act (1988). This Act contains a number of conservation and management objectives as well as Action Statements for threatened fauna. These objectives and Action Statements must be met by any proposal for use and development.

2.6 Ramsar listed wetland

Wetlands are identified as being Ramsar wetlands if they are important habitat for migratory birds. Australia is a signatory to the Ramsar treaty, and as such there is an obligation to protect wetlands that have been identified under this treaty.

2.7 Listed on the Directory of Important Wetlands (DIW)

The Directory of Significant Wetlands identifies wetlands that display the following attributes.

y It is a good example of a wetland type occurring within a biogeographic region in Australia. y It is a wetland which plays an important ecological or hydrological role in the natural functioning of a major wetland system/complex. y It is a wetland which is important as the habitat for animal taxa at a vulnerable stage in their life cycles, or provides a refuge when adverse conditions such as drought prevail.

Page 7 8/08/2008

y The wetland supports 1% or more of the national populations of any native plant or animal taxa. y The wetland supports native plant or animal taxa or communities which are considered endangered or vulnerable at the national level. y The wetland is of outstanding historical or cultural significance.

3 Land Use and Development to be managed

Various forms of land use and development have the ability to impact on the conservation values above. These decision guidelines are intended to manage the impacts of use and development. The ability of these uses and development to impact on conservation values is discussed below.

3.1 Generation of waste water

Waste waters have the ability to impact on wetlands of conservation value by altering the quality and quantity of water entering the wetland. Waste waters include run off from activities that may produce pollutants and/or nutrients (e.g. intensive animal husbandry), tail waters, disposal of irrigation water, aquaculture, Industrial discharge

3.2 Leisure and Recreation

Leisure and Recreation activities may lead to pollutants and nutrients entering surface waters. The main threatening process is from leisure and recreation infrastructure a on the wetland itself. Leisure and recreation activities within ESO 6 do not require additional scheme controls.

3.3 Mineral, Stone or Soil extraction

Mineral, stone or soil extraction has the ability to impact on ecological condition of wetlands by altering the groundwater/surface water interaction, as well as resulting in the loss of habitat, and the alteration of surface water drainage patterns.

3.4 Construction of a building

The construction of a building has the ability to impact on wetlands of conservation value by the direct activities involved in construction (excavation, sedimentation of runoff, etc) and follow on effects associated with increased hard surfaces increasing the rate of runoff during rain events, and the potential for the use of the building to generate waste water and pollutants that may enter surface or ground waters.

Page 8 8/08/2008

3.5 Removal, destruction, or lopping of vegetation.

The removal destruction or lopping of vegetation has the potential to impact on wetlands of conservation value both directly and indirectly. A direct effect of this activity could be the loss threatened flora and decrease in habitat. An indirect effect of this activity could be increased siltation of surface waters and increased rates of runoff during rain events.

3.6 Construction or carrying out of earthworks

The vegetation community that a wetland can support is dependent on the hydrological cycle (regime of wetting and drying) of the wetland. In addition to structuring the vegetation community present in the wetland the hydrological regime will also affect the types of fauna that utilize the wetland. Biological processes such as nutrient cycling and organic matter decomposition will be affected by the cycle of wetting and drying as can groundwater levels and salinity.

Of all the management actions that can impact on wetlands the effect of altered hydrology is the greatest. Earthworks include, but are not limited to, drainage, excavation, and mounding has the biggest impact on hydrology of all land use and development trigger by the overlay. Earthworks have the ability to effect wetlands through altering the local drainage pattern, resulting in either the increase or decrease of surface water flows entering the wetland and therefore changing the hydrology regime. Earthworks also have the ability to alter the groundwater/surface water interaction, which in turn can lead to an altering of the Corrik classification of the wetland and subsequent follow on effects on flora and fauna.

3.7 The construction of a fence

The construction of a fence has the ability to effect the ecological condition of wetlands of conservation value as the construction of fencing may involve mounding of soil that may alter local drainage patterns, the digging of holes that may alter the groundwater/surface water interaction. The construction materials may also have the ability to alter local drainage patterns.

3.8 Subdivision

Subdivision has the ability to impact on wetlands of conservation value by fragmenting ownership of land leading to increased difficulties in achieving management outcomes. Subdivision within ESO 6 is not an issue that requires addition control.

4 How to use the Decision Guidelines

The guidelines include a table that identifies each individual wetland and the particular conservation values it holds. Each of these values relate to environmental objectives contained in the Local Planning Policy and the Overlay Schedule.

When assessing an application for use and development, the first step is to see if the application is within ESO 5 or ESO 6. The Performance Criteria to be met will differ from ESO 5 to ESO 6 due the differentiation between the effects on a wetland being more immediate than the effect stemming from an up stream activity within the catchment of a wetland of conservation.

The Decision Guidelines identify the types of land uses and development that have the ability to impact on the ecological condition of wetlands, the environmental objective to be achieved when considering the different types of land use and development, and the criteria to be met in each circumstance.

There are 5 steps to follow which will identify the performance criteria to be met by planning permit applications. The steps are as follows

4.1 Step 1 Identify the land use and development components of the application

This is identified from the application itself and by discussions with the applicant.

4.2 Step 2 Identify which wetland of conservation value will be affected by the application

For applications in ESO 5, Shire of Hindmarsh, Wetlands of Conservation Value (WCMA 2007) map, Figure 1 Appendix 1 will have an identifying number for that particular wetland. This number corresponds to the numbers in column 2 in Table 1 (below).

For applications in ESO 6, you must first identify which wetland of conservation is connected to the catchment (ESO 6). Shire of Hindmarsh, Wetland Catchments of Conservation Value (WCMA 2007) Figure 2 Appendix 1 will have an identification number for that particular catchment. This number corresponds to the numbers in column 2 in Table 1, contained in Appendix 1.

4.3 Step 3 What attributes and values (conservation) are present in that particular wetland (Refer to Table 1)?

Step 1 identified which wetland is involved in the consideration of the application, and by looking up this wetland in Table 1, the attributes and conservation values relevant to that particular wetland can be identified.

Shire of Hindmarsh, Wetlands and Catchments of Conservation Value (WCMA 2007) . Decision Guidelines ESO 5 & ESO6 INCORPORATED DOCUMENT (AMENDMENT C6) AUTHORISATION NO. A724

Page 10 8/08/2008

4.4 Step 4 Is the land the subject of the application in ESO 5 or ESO 6 ?

This is determined by referring to the relevant ESO Planning Scheme map. You decide this by looking at the scheme map.

If the land subject to the application is in ESO 5 go to Matrix 1 in Appendix 2, or if the land subject to the application is in ESO 6 go to Matrix 2 in Appendix 2.

4.5 Step 5 Identify the Criteria to be addressed by the application.

Using the information from steps 1 and 3, cross reference the type of land use and development against the conservation values present in the wetland to identify the criteria number. Appendix 3 contains a list of the criteria that corresponds to the number in the matrix. The criteria are intended to provide guidance in forming conditions that may be placed on a permit.

For example, if an application has 2 types of use and development (e.g. earthworks and generation of waste water) and the particular wetland has 5 values (e.g threatened flora, threatened fauna, Ramsar wetland, rare geomorphic type, and wild life reserve), there will be 10 criteria identified.

It is possible that the criteria may double up, as the same criteria may address multiple situations. In this case ignore the repetition of the criteria. There is a separate list of criteria for ESO 5 and ESO 6.

5. Application Requirements The responsible authority must give notice and seek comment for all permit applications in accordance with Section 52 (1) (c) of the Act to the relevant wetland management authority specified in Clause 66.06 or a schedule to that clause. Comments from the relevant wetland management authority will involve providing a wetland condition assessment in order to determine the wetlands ecological condition, the results of which will be part of informing permit conditions.

Applications will need to demonstrate how the criteria are to be met. Information to assist applicants is available from the Wimmera Catchment Management Authority via consultation with the shire planning officer. Applicants are recommended to refer to the following Reference documents for further information when preparing applications.
