Executive Summary
Latrobe 2026: The Community Vision for the Latrobe Valley is that in 2026, Latrobe Valley enjoys a beautiful natural environment that is managed and protected with respect to ensure a lasting legacy for future generations. This municipal State of the Environment Report contributes to that vision. The Report is an objective of Latrobe City Council’s Natural Environment Sustainability Strategy 2008‐13 and a Key Strategic Action in the Council Plan 2010.
The purpose of the report is to provide objective data and transparent interpretations of the state of the local natural environment in 2010 and the trend over the past decade, to assist in rational planning for natural environment sustainability. It therefore makes no recommendations for action.
The indicators used variously relate to natural ecosystem services such as air and water), natural resource management ,and human capacity‐building for natural environment sustainability (see figure opposite).
The condition scores (using a 4‐point scale of very poor, poor, good and very good) of all the indicators in each of these three sectors have been summed to produce an overall ‘barometer’ of the state of the Latrobe City environment in 2010 (see figure opposite). The summary indicates good capacity‐building for sustainability, and natural resource management and ecosystem services sectors in reasonable condition but with room for improvement.
The trends in the indicators over the past decade have also been summed to show the overall direction. The figure opposite plots, for each area, the proportion of environmental indicators that have shown an overall improvement over the decade (in white) and the number that have shown an overall deterioration (in black). Capacity‐building has generally improved, the natural resource management sector has most indicators improving but some deteriorating, and the ecosystem services sector is about half and half.

Introduction
INTRODUCTION TO LATROBE CITY’S LOCAL STATE OF THE ENVIRONMENT REPORT
BackgroundThis report is an action under Latrobe City Council’s Natural Environment Sustainability Strategy 2008‐2013 and a Key Strategic Action in the Council Plan 2010‐11. Latrobe 2026: The Community Vision for the Latrobe Valley is that in 2026, Latrobe Valley enjoys a beautiful natural environment that is managed and protected with respect to ensure a lasting legacy for future generations. Latrobe City is grateful to the Commissioner for Environmental Sustainability and her staff for their advice and discussions in the development of this report.
The purpose of the Latrobe City local State of the Environment reportThe purpose of this State of the Environment report is to assist rational debate on natural environmental conservation, by providing an objective basis against which to judge the state of the local natural environment and the trend. Understanding the state of the environment is critical for decisions on whether action is needed or not, and whether current action is effective. It is not the intent of this report to ‘green‐wash’ existing activities to justify ‘business as usual’; nor to advance environmental agendas at the expense of existing interests. To this end, the data used is science‐based and its interpretation has been judged (wherever possible) in comparison with criteria adopted by government agencies, e.g. the State policies for air and water quality. Where such criteria are not available, other non‐partisan standards have been used.
ScopeThis State of the Environment report provide indicators primarily for the natural environment and ecosystem services, but it also includes indicators extraction and consumption, waste and incidentals which
The process – components, indicators, data, assessments and trendsThis State of the Environment report first needed to identify the key components of the environment whose state needed to be assessed: it uses the components identified during the development of Latrobe City Council’s Natural Environment Sustainability Strategy 2008‐2013 (e.g. water, air, community capacity for sustainability) because these were developed with extensive input from experts and agencies and broad community consultation. Next, appropriate indicators were identified and populated with data. Indicators have been developed using expert advice and based on the availability of data preferably over the previous decade. A variety of internal and external data sources have been used and these are acknowledged in the relevant sections. Finally, the data had to be interpreted: appropriate standards were identified and scales developed to provide qualitative assessments of the meaning of the quantitative data; and a standard statistical technique (regression) was used to determine the overall trend of the data over the decade.

Introduction
CASE STUDYA Latrobe City Council experiment on the reliability of environmental assessments
Interpretation of data and assessments of the state of the environment can be subjective. This is a particularly relevant consideration in areas such as forestry where there are both passionate advocates and opponents. When a representative sample of the Latrobe City community was asked in the 2003 community survey whether compliance with the Code of Forest practices should be audited by environmental experts or forestry experts, the overwhelming community view was that both were required for a balanced opinion. In the first part of the decade, Latrobe City engaged third‐party environmental specialists to assess compliance, and then from 2004 used forestry specialists. Are the assessments comparable and equally objective?
To satisfy community concerns, Latrobe City Council used two reputable teams of experts ‐one natural environmental science specialists and the other natural resource management (forestry) specialists ‐ to conduct parallel audits. The two teams were asked to assess both compliance of forestry operations with the State Government Code of Forest Practices for Timber Production 1996, and the environmental impact of those operations.
The results were encouraging. Both teams agreed very closely on the degree to which harvesting complied with the Code set by State Government, even though the natural environmental science consultants estimated environmental impact significantly higher than the natural resource management consultants. This indicates that experts with different expertise are able to agree on whether performance meets established criteria, even if their overall opinions about the environmental impacts differ.
Correlation of Code compliance assessments. If assessments are equivalent, they should fall along the dotted line. The ”line of best fit” of the actual assessments (the solid line) fits this almost exactly, indicating that the consultants were in agreement on compliance.
Correlation of environmental impact assessments. If assessments are the same, they should fall along the dotted line. The “line of best fit” of the actual assessments (the solid line) is shifted away from the dotted line, indicating a difference of opinion between consultants on environmental impact.

Introduction
STRUCTURE OF THE REPORT
The sections in this report reflect the Action Areas identified in the development of Latrobe City’s Natural Environment Sustainability Strategy 2008‐13, with some re‐organisation. The relevant action areas in the Strategy are referenced. Each section describes the indicator, the data, current condition and the overall trend over the past decade. Annual values for the last ten years are graphed where available and additional background data is provided in many cases.
IndicatorsIndicators have been selected based on the availability of relevant data over the decade, their relevance to the state of the natural environment and their relevance to Latrobe City’s adopted Natural Environment Sustainability Strategy 2008‐13. Wherever possible, ‘obvious’’ indicators have been used, for example, the air quality indicator of how many kilometres one can see before the dust haze obscures ones view. On the other hand, the indicator for bird biodiversity uses a mathematical equation based on species and numbers, because species and bird counts without this manipulation indicate how many birdwatchers there were and how many sites they visited, not biodiversity. The indicators have been graphed to reflect the overall performance.
DataThe “data” section outlines the data used, how the indicator was calculated and the source of the data. The full data sets used are stored on the Latrobe City Council computer system.
Trend and Condition‘Trend’ reflects whether the indicator has, overall, improved or deteriorated over the decade. Where the overall trend is unclear, a statistical ‘line of best fit’ (linear regression) has been calculated to determine the overall trend. Note that an indicator that has increased may have improved or it may have deteriorated, depending on the indicator, for example, an increase in the turbidity of water means that the quality has deteriorated, whereas an increase in bird biodiversity means that the indicator has improved. An overall condition score for the most recent year is also provided, rated on a 4‐point scale of “very poor”, “poor”, “good” or “very good”. This is a judgment based on the data and a set of criteria established and listed at the end of this document. Wherever possible, they are based on accepted standards . e.g. the national target for the protection of ecosystems is 15%, so the current protected area of less than 5% of Latrobe City has been classified as “very poor”, 5‐10% would be considered “poor”, 10‐15% “good”, and above 15% “very good”. As another example, ICLEI developed a scale for progress towards sustainability –Latrobe City scored 54% on that and so is rated “Good” because 54% is in the third quartile (50‐75%) of possible scores.
Additional dataThe ‘Additional Data’ page includes more detail on the indicator and related information, e.g. for water quality, a map of watercourses in Latrobe City and a list of the State Environment Protection Policy objectives for lowland rivers.

A Barometer of the Condition of Latrobe City's Natural Environment 2010
Summing the scores (1 ‐ very poor, 2 – poor, 3 – good, 4 – very good) indicates that Latrobe City’s capacity building to address environmental issues is good, and our natural resource management is fairly good, but ecosystem services could be improved in a number of areas.
Summing the indicator scores and plotting the scores as a percentage of the maximum provides an indication of the overall condition of natural environment sustainability in Latrobe City in 2010. The results suggest that Latrobe City’s capacity building to address environmental issues is good, but natural resource management and ecosystem services could perform better.
Summing the number of indicators that show environmental improvement over the decade, and the number that show deterioration, provides an indication of the overall direction of natural environment sustainability in Latrobe City. Capacity has shown an overall improvement, most natural resource management indicators have improved but several have deteriorated, but while many ecosystem service indicators are improving, as many are deteriorating.

Building capacity for sustainability
ICLEI “Progress Towards Sustainability” indicatorThe indicatorDuring 2009‐10, 6 regional cities and eight rural shires in Victoria participated in the International Council for Local Environmental Initiatives (ICLEI ) Sustainability Integration Self‐assessment Tool program. Guided by ICLEI facilitators, this provides a self‐assessment of the degree to which sustainability has been integrated into Council processes.
The dataLatrobe City Council’s internal Sustainability Steering Group rated Council operations using the SISAT questionnaire of 84 questions, each with four specified levels of performance. The scores were further informed by short‐version assessments completed by management. The results from other participating municipalities were provided by ICLEI.
The trendLatrobe City actions contributing to the SISAT scores commenced in 2000 and have progressed over the decade, but only one assessment has been undertaken. Latrobe City achieved the second highest score overall (54%) of the fourteen participating municipalities. Regional cities generally scored higher than rural shires. The two areas (there were eleven in total) where Latrobe City achieved its lowest scores were on “establishing the business case” and on “policy adoption”. Latrobe City achieved the highest scores among participants for “political commitment”, “strategic and corporate planning” and “performance measurement”.

Local regulatory framework
Planning Zone size changesThe indicatorThe purpose of planning is to provide for appropriate, predictable and orderly development, use and conservation of land, both now and in the future. Under the Planning and Environment Act 1987, there is a statewide system of zoning of land to regulate the particular land use and development permitted there. Such zones include residential, business, industrial, farming, public purposes, roads and special use. Each zone (e.g. the Residential Zone) may be subdivided (e.g. into Residential 1 and Residential 2) to provide more particular regulation, listed in the Schedule for that zone. Local Government is responsible for administering the Planning Scheme in its own municipality. Changes to zones require extensive public consultation and the approval of the State Minister. Changes in the area of Planning Zones reflect changes in how land is expected to be used and developed. A slow rate of change in land zoning is generally indicative that the zones have been well‐planned to accommodate both present and future needs.
The dataData on the current size of each planning zone in Latrobe City is stored in the Latrobe City GIS. Details of changes are listed on the Department of Planning and Community Development website at http://www.dse.vic.gov.au/planningschemes/latrobe/home.htmland the areas of parcels whose zoning has changed in each Planning Scheme amendment have been calculated from the polygons stored on the Latrobe City GIS. The indicator used here ignores differences in the zone schedules and groups zones by their standard Zone name.
The trendDriving into Melbourne, It is easy to get the impression that urban sprawl is rapidly engulfing agricultural land. However, in Latrobe City, zoning changes have generally been very small (0.16% of the land area over 5 years). The main change between 2005 and 2010 has been a shift of some 100 ha of the Farming Zone to the Industrial Zone (the Farming Zone in Latrobe City still covers over 95,000 ha). Changes affect only a fraction of a percent of Latrobe City.

Industry Sustainability
Industry action for sustainabilityThe indicatorThe number of organisations producing statutory Environment and Resource Efficiency Plans is an indication of progress towards sustainability of the the larger resource users. The Accredited Licensee program indicates progress beyond compliance.
The Victorian Environment Protection Authority (EPA) requires businesses using more than 100 TJ of energy and/or 120 ML of water each year (each the equivalent of 2000 average Victorian households) to have an Environment and Resource Efficiency Plan (EREP) designed to achieve environmental benefits and cost‐savings in a short time‐frame. Other businesses can participate on a voluntary basis.
The Victorian EPA states that “The Accredited licensee system is designed to provide companies having sound technical and environmental management systems, together with the commitment to good environmental performance, to be freed from the standard prescriptive approach to works approval and licensing. To be an accredited licensee, the overriding requirement is to demonstrate a high level of environmental performance and an ongoing capacity to maintain and improve this performance.”
The dataThe Victorian EPA publishes a list of organisations enrolled in the EREP scheme and organisations receiving Accredited Licences.
The trendEREPs were only introduced in 2008, hence there is insufficient data to develo a trend at this point in time. However, implementation of this system indicates improvement in environmental reporting.

Industry Sustainability
Industry action for sustainabilityThe indicatorThe indicator is based on voluntary steps including policy adoption, target setting, reporting and progress on achieving targets by the major health, education and government organisations in Latrobe City. These steps indicate capacity‐building in terms of recognition of the issue, setting targets, implementation of actions to achieve those targets, spreading the message by public reporting and actually achieving the targets for energy efficiency.
The dataAnnual data for past years has not been sourced. The table represents the situation in 2010.
The trendThere is progress on all five steps but still a way to go to achieve 100% in terms of ticking all the boxes – current performance overall averages 60%.

Community environmental action
Community Environmental Sustainability GroupsThe indicatorThere are a variety of local community groups active in the area of environmental sustainability in Latrobe City. They include independent, voluntary groups, advisory and review committees and Committees of Management established by government or industry.
The number of active community environmental groups is an indicator that tells us the pro‐active nature of the community in environmental sustainability, and also of the level of community interest for environmental sustainability. In the USA, one study found 1 environmental group per 11,500 and 1 per 19,500 (Kempton et al, 2001.Local Environmental Groups: A Systematic Enumeration in Two Geographical Areas. Rural Sociology 66:557‐578) which would suggest 4‐6 groups might be found in Latrobe City. In this study, environmental groups included school groups, which are not included here. Cardinia Shire and Port Macquarie‐Hastings Shire, both with a population about the same size as Latrobe City, report 9 and 18 voluntary local environmental groups respectively.
The dataLatrobe City Council maintains a database of environment‐related community organisations based in Latrobe City. Latrobe City Council is also represented on most of the appointed organisations. Organisations included in this data set are shown in the table opposite. The indicator does not include groups with a wider geographical remit such as the Gippsland Climate Change Network, nor Steering Committees for projects such as Environment Victoria’s Sustainable Living Program, nor the various advisory committees to the West Gippsland Catchment Management Authority.
The trendThere are now 18 independent voluntary environmental groups and 36 local environmental organisations in total operating in Latrobe City (approximately one for every 2000 residents). Between 2000 and 2010 there has been a 29% increase in the number of local organisations addressing environmental sustainability, indicating increasing interest and action.

Community environmental action (b)
Participation in the Native Vegetation Retention Incentive SchemeThe indicatorLatrobe City Council’s Native Vegetation Retention Scheme commenced in 2000 and offers a limited number of small grants (averaging around $400 each) as a contribution towards native vegetation retention and enhancement. The incentives are available for private properties over 4 hectares with remnant native vegetation. There are 1990 private properties over 4ha in Latrobe City. This Scheme also supports properties covenanted with Trust for Nature, which are also used as an indicator in this report (see later under Biodiversity Conservation)
The dataA record of successful applications is maintained by Latrobe City Council. It includes both projects and annual payments for land protected under a covenant with the Trust for Nature. The indicator is the total number of properties that have participated. Some properties have successfully applied for support for projects in more than one year, and covenanted properties are supported with annual payments. The indicator records each property only once, in the first year that it participated.
The trendThe number of participating properties has continued to increase and now totals 6.7% of private properties over 4ha. Around 10% of the remainder (216 of the 1990) are owned by multi‐nationals or government, and these would not normally apply, and many properties are cleared and not normally eligible. There is no accepted standard for community participation. Where Landcare groups are established, 41% of local landholders participate (Allan Curtis and Penny Cooke 2006 Landcare Groups in Victoria: after twenty Years A report to the Australian Government Department of Agriculture, Fisheries and Forestry, National Landcare Program, Monitoring and Evaluation Project), but the Landcare program potentially attract a wider audience because it also subsidises agricultural production by addressing externalities such as weeds and erosion. A survey by the Australian Bureau of Statistics in 2007 (4441.0 ‐ Voluntary Work, Australia, 2006) found an Australian participation rate in voluntary work to protect the environment of 2.3%. 2% is used as the mid‐point of the report card scale.

Air quality (a)
Airborne chemical pollutant concentrationsThe indicatorThe Indicator is the number of days per calendar year compliant with State Environment Protection Policy (SEPP) Objectives for concentrations of Sulphur Dioxide, Nitrogen Dioxide, Airborne Particles (PM10) and Ozone.•Sulphur dioxide (SO2) is produced by volcanoes, industrial processes and transport, particularly the combustion of fossil fuels. It can cause respiratory problems in humans and is a precursor chemical for acid rain and the formation of airborne soot particles. •Nitrogen oxides (NOX) are produced by the combustion of fuels. Approximately half comes from vehicles, a quarter from coal‐fired power stations and the remainder from industrial, commercial and residential activities. Nitrogen dioxide may cause various health impacts on humans. It is a greenhouse gas. It can damage vegetation and reduce crop yield, and contributes to the formation of smog, acid rain and ground‐level ozone. •Ozone (O3) is produced by the chemical reactions from fuel combustion in vehicles and power stations, but also from bushfires. Ozone can produce ground‐level photochemical smog, affect the heart and respiratory system, and damage vegetation growth, buildings and other materials.
The dataAir quality monitoring of these and other air quality parameters occurs at a number of sites in the Latrobe Valley, under the auspices of the Latrobe Valley Air Monitoring Network. Detailed air quality data can be accessed at http://www.powerworks.com.au/airquality.asp
The trendOverall, the level of chemical pollutants in the air has been stable or declined. The peak of Nitrogen Dioxide in 2009 is a direct consequence of the Black Saturday bushfire.

Air quality (b)
Airborne particle concentrations and minimum visual distanceThe indicatorThe Indicator is the number of days per calendar year compliant with State Environment Protection Policy (SEPP) Objectives for concentrations of Airborne Particles (PM10) and the minimum local visual distance on any day in the year.•Airborne particles are generated by burning fossil fuels and are produced by vehicles and industrial processes, and also from domestic solid fuel heaters and bushfires. Particles smaller than 10 micrometres (smaller than most plant pollen – there are 1000 micrometres in a millimeter) can penetrate deep into the lungs and cause respiratory problems. •Local Visual Distance reflects the density of airborne particles of all sizes in the air.
The dataAir quality monitoring of these and other air quality parameters occurs at a number of sites in the Latrobe Valley, under the auspices of the Latrobe Valley Air Monitoring Network. Two measures for PM10 particles are given because this indicator is measured using two different methods. Detailed air quality data can be accessed at http://www.powerworks.com.au/airquality.asp

Water quality in rivers and streams (a)(NESS Action Area 6)
Water flow – amount of water coming down the river
The indicatorThe main river in Latrobe City is the Latrobe River. The Latrobe River flows from Baw Baw Shire through Latrobe City to the Gippsland Lakes, a wetland of international importance. There are a number of waterways and rivers that flow from the Great Dividing Range to the north and from the Strzelecki ranges to the south. An adequate water flow is critical for the health of the waterway and the Lakes, for agriculture, for households and for the Latrobe Valley industries. Very high flows can involve flooding, and low flows reflect drought and water shortages.
The dataThe Indicator uses data monitored at Scarnes Bridge, on the Latrobe River north of Traralgon. This is located relatively near the downstream end of the river in Latrobe City and flows here reflect water leaving Latrobe City.
The trendWater flow has declined over the decade but overall demand for residential and industrial use is increasing.

Chemical pollutants – Nitrogen and Phosphorus concentrationsThe indicatorNitrogen and Phosphorus are both essential for plant growth and extensively used as fertilisers, High concentrations in the river result from urban and agricultural runoff and can lead to eutrophication (nutrient enrichment) and algal blooms.
The dataData from monitoring at Scarnes Bridge, on the Latrobe River north of Traralgon, is used because it is located relatively near the downstream end of the river in Latrobe City and has received some of the most comprehensive monitoring over the decade. No single datasets span the whole decade and the data presented here is a composite from two different labs. The original data can be accessed at the Victorian Water Data Warehouse. Where data tables on total Nitrogen has not been available, this has been calculated from measurements of Kjeldahl Nitrogen (which excludes organic nitrogen, ammonia and ammonium) and measurements of Nitrate and Nitrite. Differences in measurements can arise both from different sampling times and from differences in sampling technique and laboratory procedures. The data points are averages per year based on monthly samples. Averages can be influenced by occasional very high readings, but are generally indicative of the level of these chemical pollutants.
The trendConcentrations have generally decreased over the decade but there are still significant quantities in the water compared to upstream reaches less affected by human activities.

Sediment load – suspended solids and turbidityThe indicatorThe amount of particulate matter in the water reflects the amount of soil and other material being transported by the river. Heavy sediment loads indicate soil erosion and can reduce light penetration and reduce photosynthesis by aquatic plants, reducing oxygen concentrations, biodiversity and general river health.
The dataData monitoring at Scarnes Bridge, on the Latrobe River north of Traralgon, is used because it is located relatively near the downstream end of the river in Latrobe City and has received some of the most comprehensive monitoring over the decade. No single datasets span the whole decade, and so data on both turbidity and suspended solids are presented. Turbidity is a measure of light penetration through the water, which is affected by the amount of suspended solids but also their shape and size, while suspended solids is a direct measure of suspended matter >0.45mm in size. Both measures show a good correlation at the sampling site.
The trendSuspended solids and turbidity have generally increased over the decade.

Protect our water supply (a)
Residential water consumption (litres per person per day)The indicatorProtecting our water supply requires ensuring demand does not exceed supply. Annual rainfall has decreased over the decade and further long‐term reductions are predicted, including an increased demand due to higher temperatures and increasing population. Supply is therefore subject to factors outside our direct control, but demand is within our control. Decreasing our water use and any water wastage is important for ensuring this resource. The main use of potable water is for residential purposes. Residential water use is therefore a good indicator of the degree to which we are protecting our water supply.
The dataData is provided by Gippsland Water and is based on metered use at residential proerties plus estimates of use for unmetered residential properties.
The trendIn the 1990s the average daily residential consumption in the Gippsland Water supply area was 244 litres per person per day. Gippsland Water has a target of an average of 183 litres per day by 2015. In 2009‐10, average consumption in Latrobe City was 193 litres per person per day.

Soil conservation
The indicatorSoil conservation includes both the quality of the soil in situ and soil erosion and transport. Soil quality is affected by agriculture and forestry practices, and soil erosion by those and also activities such as roading, mining and removal of vegetation cover.
No indicator of soil quality has been developed for this report, but two indicators used elsewhere in this report are relevant to soil erosion: compliance with the Code of Forest Practices is an indicator of the extent to which harvesting practices minimise soil entering watercourses; and suspended solids in water are an indicator of the amount of eroded soil being transported down‐stream.
For further information on these indicators, see the sections on Water Quality and the Code of Forest Practices.

Action Area 7: Biodiversity Conservation
Municipal native vegetation coverThe indicatorThe extent of native vegetation is a direct indicator of the area of land devoted to providing essential ecosystem services such as soil stability and condition, clean air, clean water and biodiversity. Some native vegetation may also provide significant economic value, e.g. from grazing and timber harvesting. Below around 30% of native vegetation cover across the landscape, there is a significant and accelerating increase in biodiversity decline (West Gippsland Regional Vegetation Plan, 2004).
However, despite its high importance as an indicator of a sustainable environment, the extent of native vegetation over an area such as Latrobe City requires a major investment of resources and expertise to map and therefore data is not regularly updated.
The dataThe extent of native vegetation in Latrobe City was mapped by the Department of Natural Resources and Environment at a scale of 1:25000 using aerial photographs and ground‐truthing between 1995 and 2000. The Department also developed a computer simulation of the types and extent of native vegetation prior to European settlement. Date extent and type in 2000 were provided by the Department in 2000 (PLMMT100 dataset in DNRE CGDL, 2 February 2000). Native vegetation extent has not been re‐mapped since.
The trendThe extent of native vegetation has declined significantly since European settlement, and is estimated to have reduced to about 23% of Latrobe City in 2000. If the contribution of native plantation is included, this rises to 30%; however, over time, native plantation management may reduce its contribution to native vegetation values. The extent of native vegetation in 2010 and trends are unknown. Revegetation projects have been undertaken but losses have also occurred, e.g. from illegal clearances and bushfires, and a survey of roadside native vegetation in Latrobe City in 2003 showed a 28% reduction in High Conservation roadside native vegetation over the previous 8 years. Therefore the trend is listed as “Deteriorated”, but this needs verification.
Overall condition in 2010: POOR. Trend: DETERIORATED (?)

Bird diversity ‐ Annual Bird Count of best birding sitesThe indicatorBirds are a good indicator of environmental condition because there are a diverse range of species, they are relatively mobile, and relatively easily identified. Bird were critical indicators, for example, of the harmful effects of persistent organo‐chlorine pesticides in the 1960s. The indicator used here is the species richness and diversity of birds recorded in the annual Latrobe Valley Bird Count. The counts are done in the ‘best’ birding sites, which represent the core areas for bird biodiversity. These should be the most resilient areas. If environmental sustainability declined, bird populations would be expected to decline first in the less optimal habitat outside such core areas, with numbers of individuals falling first and then next, species becoming locally extinct. Any decline in the bird biodiversity of core areas would therefore be of significant concern.
The dataThe data has been collected by the Latrobe Valley Field Naturalists Club during its annual bird count in December each year. The number of observers varies each year and the sites visited sometimes vary due to accessibility issues (e.g. some sites such as the Morwell River Wetlands are on private property), which can effect sightings. The upward trend in species and bird numbers during the early years likely represents an increase in participants and sites visited, and counters “learning” how to maximise their sightings. The Indicator is the Shannon Diversity index which combines species richness (the number of species) and species equitability (the evenness of the number of individuals per species). This index is relatively independent of the number of observers or sites visited and tends to give values between 0 and 4.6. Highest diversity is when each species is represented by the same number of individuals. For example, a site with just two species, each with 50 individuals, would have an index of 0.69, whereas another site also with two species, but with 99 of one and one of the other, would have an index of 0.06.
The trendBird biodiversity is stable or increasing slightly. The Shannon Diversity Index for 2010 was the second highest of the decade.

Bushland parks and reserves (a)
Extent of bushland reserves with formal protectionThe indicatorNative vegetation is generally protected by law but may be subject to removal under permit, cleared illegally or degraded by grazing or other use. The most secure native vegetation is that which is declared and formally managed for its natural values by government, or bushland subject to a binding legal agreement in perpetuity.
National guidelines indicate that the reservation of 15% of the pre‐European distribution of forest eco‐systems is desirable, although in some cases 10% may prove adequate (Nationally Agreed Criteria for the Establishment of a Comprehensive, Adequate and Representative Reserve System for Forests in Australia. A Report by the Joint ANZECC / MCFFA National Forest Policy Statement Implementation Sub‐committee. Commonwealth of Australia 1997).
The dataThe indicator includes public land managed by Parks Victoria, Council bushland reserves and private land covenanted with Trust for Nature. The indicator is an underestimate of protected bushland insofar as it does not include non‐binding agreements such as Land for Wildlife properties, land managed for biodiversity by industry such as the Morwell River Wetlands, or native vegetation potentially protected by Section 173 agreements under the Planning and Environment Act, because these are more difficult to monitor and may represent a lower level of protection of biodiversity values.
The trendThe proportion of land formally protected for its natural values in Latrobe City in 2010 is 2.6%. This is well below the nationally accepted levels of 10‐15% for ecosystem reservation. There has been a gradual increase in the extent of private land set aside under Trust for Nature covenants.

Number of private properties adopting a Trust for Nature CovenantThe indicatorTrust for Nature is a statutory body, established under the Victorian Conservation Trust Act 1972 to protect native vegetation on private properties. A Trust for Nature Covenant is a voluntary agreement between the landholder and the Trust to protect native vegetation in perpetuity, and has to be endorsed by the Minister. The number of properties adopting covenants reflects both the extent of formal native vegetation protection on private land and landholder commitment to preserving natural values for the public good.
The dataDetails of Trust for Nature Covenants are confidential between the Trust and the landholder. However, covenants are recorded on title and are a consideration in calculating the rateable value of the property, and the Trust therefore provides information on covenants to local government.
The trendThe number of Trust for Nature covenanted properties has gradually increased over the decade. In 2010 there were 12 covenanted properties out of 1986 possible properties in Latrobe City (0.6%).

Timber production – environmental compliance
Code of Forest practice Audit resultsThe indicatorForestry in Victoria is governed by the Code of Forest Practice, an incorporated document in the local Planning Scheme. Latrobe City Council is the responsible authority for compliance with the Code on private land. The declared purpose of the Code (2nd edition, 1996) is to “lay down Statewide goals and guidelines… to ensure…• Adequate regeneration and management following timber harvesting, • Efficient reforestation with environmental care, • Protection of environmental values, and • Provision of opportunities for recreation, scientific study and education.”The Indicator measures compliance with the Code, which sets statewide criteria. It does not take into account particular local conditions and it does not directly measure environmental sustainability.
The dataSince 2000, Latrobe City Council has conducted random audits of timber harvesting coupes in Latrobe City using an audit tool developed by Gippsland local governments and third‐party auditors. Each coupe is rated compliant or non‐compliant against a range of criteria, and the results grouped under six issues: Timber Harvesting Plan, Coupe siting and design; Water Quality Protection – Buffer and Filter Strips; Conservation of flora and fauna and Management of Rainforest; Log Landings and dumps; Extraction tracks; and roading. The indicator does not distinguish between major and minor breaches of the Code, and a coupe may be deemed non‐compliant on a criterion even if it is 99% compliant on that criterion overall, e.g. one non‐compliant road drain even where all the other road drains are complaint.
The trendPerformance improved substantially in the early part of the decade and high compliance has been maintained through the latter part of the decade. The overall compliance in the 2010 was 97%

The net area harvested each year has shown a slight increase over the decade (Data from Latrobe City Timber Harvesting
register).
A sustainable timber industry makes a major contribution to the economy and environment of Latrobe City. Latrobe City Council is the Responsible Authority for the Victorian Code of Forest Practices. Under the Planning Scheme, Timber Harvesting Plans are the fundamental document for the control of timber production on private land and a register is maintained by Latrobe City Council. Over the decade, measures of timber production in Latrobe City indicate a generally stable pattern of production. Based on data from the Latrobe City Timber Harvesting register, on average less than 5% of the plantation area has been harvested each year, there has been a slight increase in the area harvested each year, and timber volumes per hectare have remained constant.

Materials consumption
Corporate copy paper useThe indicatorA key problem for sustainability is excessive consumption. The amount we consume personally is limited by price, but the amount consumed in the workplace does not have the same price signal for individuals. The use of copy paper is an indication of how much sustainable behaviour is embedded in individual behaviour in the absence of a price signal. Copy paper use is likely a good indicator of overall consumption habits. While the amount of paper used in publications can vary significantly and reflects outside pressures, copy paper use tends to more directly reflect staff behaviour. Data on copy paper use is also available for State Government Departments in the Victorian State of the EnvironmentReport 2008.
The dataThe amount of copy paper and letterhead purchased each year is recorded in Latrobe City Council’s Accounts Receivable records. Generally a single supplier is used at any one time and is able to provide a summary of paper supplied including sizes and weights.

Weed infestations
Length of roadside infested with BlackberryThe indicatorThere are a number of listed noxious weeds that have been reported in Latrobe City but Blackberry (Rubus fruticosus agg.) is the most abundant. Blackberry is also classed as a Weed of National Significance. Blackberry on roadsides is a potential source of infestations in adjacent native vegetation and agricultural land, and is a threat to roadside native vegetation. The extent of blackberry on roadsides may or may not reflect the scale of blackberry infestations on public and private land throughout Latrobe City, but it potentially affects adjacent land and roadsides are accessible for monitoring. Roadside weeds are the responsibility of the adjacent landholder but State Government has been supporting Local Government to take action on roadside weeds on behalf of its local community
The dataThe majority of rural roadsides in Latrobe City were surveyed for blackberry in 2009‐10 with funding from the Department of Primary Industries through the Future Farming Building Capacity of Local Government (BCLG) program. No previous assessments of the scale of infestations have been made. With assistance from the BCLG program and Bushfire recovery Program, Latrobe City Council undertook blackberry control works during 2009‐10 and 2010‐11 and many of the rural roadsides in Latrobe City, with the aim of significantly reducing the extent of roadside blackberry infestations.
The trendThe trend is unknown. There have been previous schemes to assist rural landholders to address weeds on adjacent roadsides, but there have also been events such as the Black Saturday bushfires and the wet summer of 2010‐11 which have increased the potential for infestations. The trend is listed as “Improved” due to the large amount of roadside weed control undertaken between 2009 and 2011 with support from the Department of Primary Industries Building Capacity of Local Government funding program, but the trend needs to be verified.

Waste management
Garbage per person to landfill from the kerbside collectionThe indicatorThere are numerous waste streams going to landfill or recycling, but residential waste is a major component. At the beginning of the decade residential waste constituted approximately half of all the waste going to landfill. In 2004‐5 a three‐bin system was introduced to Latrobe City and recylables and organic greenwaste were diverted from landfill to recycling facilities. This has diverted a significant volume of waste from landfill. As other materials and markets are identified to reuse, recover and recycle’waste’ products, there should be a continued decline in the volume of waste produced. Sustainability Victoria and EPA Victoria estimate that Victoria produces an average of half a tonne of garbage per household per year.
The dataData on kerbside collections is derived from weighbridge records at the landfill. The variety of waste streams, and the inclusion of different waste elements in the calculations, along with small uncertainties about the exact number of people in Latrobe City, provide some margin for error in the figures, but the overall trends are indicative.
The trendThe amount of residential garbage going to landfill has reduced over the decade but the figures suggest a slight upward trend over the last few years. There is still a large volume of waste produced per person and per household with opportunity to reduce.

Residential energy use and greenhouse emissionsThe indicatorThe residential sector is a significant user of energy and a significant emitter of greenhouse gases. In 1998, residential emissions in Latrobe City were estimated to comprise 12% of emissions from the municipality (excluding power station emissions). In 2008‐9, the Department of Sustainability and Environment estimated that residential emissions comprised about 17.5% of Victoria’s total emissions (http://www.climatechange.vic.gov.au/greenhouse‐gas‐emissions/residential‐energy‐use).
In terms of energy, we use more natural gas energy than electrical energy in the home, but gas produces far less in terms of emissions. 85% of residences in Latrobe City have gas connected. A kilowatt hour of electricity produces 1.048 kg of carbon dioxide equivalent, whereas a kilowatt hour equivalent of natural gas produces only 0.019 kg of carbon dioxide equivalent (1 Gigajoule of natural gas is the energy equivalent of 277.8 kWh of electricity).
The dataThe data used for the indicator was compiled by the Department of Sustainability and Environment using data from 2004 to 2007 from Victorian electricity and gas providers. The data is available athttp://www.climatechange.vic.gov.au/__data/assets/pdf_file/0008/73367/37‐Latrobe_C_.pdf

Latrobe City Council corporate energy use and greenhouse emissionsThe indicatorCorporate electricity, natural gas, vehicle diesel, petrol and LPG, streetlights, and a small estimated amount for corporate waste, comprise Latrobe City Council’s energy consumption from which its corporate greenhouse gas emissions can be calculated (municipal waste collected by Council is listed under community emissions).
The dataLatrobe City Council undertook a detailed audit of corporate energy use and greenhouse emissions in 1998 as part of the ICLEI Cities for Climate Protection (CCP) program. All gas, electricity and vehicle fuel invoices and receipts for 1998 were input into the ICLEI CCP database. Since 2005‐6, Latrobe City Council’s energy usage has been collated and analysed by Planet Footprint on behalf of Latrobe City Council, using electronic invoices direct from the energy suppliers.
The trendEnergy use and consequent emissions have been increasing over the decade. There is an overall relationship between corporate energy use and emissions, and the increase of Council services as represented by equivalent full‐time staff numbers and facilities.
Overall condition in 2010: POOR. Trend: DETERIORATED

The increase in latrobe City Council’s corporate emissions generally maps the increase in Council staff which reflects increased Council services
Data is not available for the first half of the decade, but emissions per staff member in 1998 were relatively high, then appear to have declined when the new HQ building became operational. However, emissions per staff member have subsequently crept up again.

Changing rainfall and temperatureThe indicatorClimate change predicts a reduction in rainfall and also increasing temperatures which will increase water requirements for agriculture. There is likely to be an increase in human demand for water, and increasing temperatures pose health risks to vulnerable members of our society. Risk of bushfire will increase. The amount of rainfall and the increase in very hot days are therefore important indicators of climate change and the need to adapt.
The dataRainfall and temperature data is currently collected at Latrobe Valley Airport and available through the Bureau of Meteorology (BoM). Where the data may be incomplete, there are often other data sets from nearby locations that can provide a good indication of total rainfall. Datasets from nearby locations can be found on the BoM website. Composites from local stations have been used to provide a more complete picture.
The trendOver the last decade, Latrobe Valley has generally become drier and hotter.

Natural disasters ‐ bushfiresThe indicatorBushfire risk is expected to increase with climate change and global warming.
The dataThe Department of Sustainability and Environment maintains bushfire information on its interactive map at http://nremap‐sc.nre.vic.gov.au/MapShare.v2/imf.jsp?site=fireplan . And these bushfire areas are mapped onto the Latrobe City GIS database where they impact on private property.
The trendThere were fires in the Alpine area to the north and Wilsons Promontory to the south in the early part of the decade, but these missed Latrobe City. The 2005‐6 the Moondarra fire impacted on Latrobe City, as did the Great Divide fire of 2006‐7. In 2008‐09 the Black Saturday bushfires impacted a much larger area of Latrobe City.
