Ginninderra

Site tour leads the conservation conversation

The conservation conversation was front and centre as members and experts from ACT environmental groups visited CSIRO’s Ginninderra Property on 6 June.

The question of: “How can we conserve and restore important environmental features within and beyond the boundaries of a proposed future urban development?” was top of mind as the group visited nine key sites across the property.

CSIRO researchers and expert consultants explained the findings of ecological surveys and their interpretation of key environmental features on the site, while also seeking initial advice and ideas from participants who included members from the Conservation Council ACT Region and its Biodiversity Working Group, Friends of Grasslands and the Ginninderra Catchment Group.

Throughout the tour, participants studied maps of the Ginninderra property showing CSIRO’s initial assessment of developable land (360.8 ha or 51% of the site), potential developable areas under review (129.4 ha, 18%), areas primarily protected by current legislation (130.9 ha, 19%) as well as additional areas CSIRO has set aside to protect conservation and heritage values (80.5 ha, 12%).

Some of the key features for mandatory protection are:

Other areas or features earmarked by CSIRO for protection include:

Some important questions raised on the site visit included the need to define the boundaries for conservation areas and clarify the buffer and transition zones between areas under development and those under conservation. Road access within and to the site will also be an important factor in realising conservation goals.

Establishing sound principles for conservation and development from the outset was seen to be an essential ingredient for success.

So, coming back to the question: “How can such conservation and even restoration be successful in close proximity to an urban development?’” Based on early advice from conservation experts – it won’t happen by accident – but rather through diligent assessments, and applying clear principles and careful planning and implementation.

CSIRO is keen to do exactly that and to develop principles and plans with experts and the broader community through a participatory planning process.

The next steps are to further develop these conservation principles with the same groups through a workshop in late June and to follow that up with some broader community engagement in July.

The environmental principles and plans will then form part of the briefs for the eventual joint venture development partners selected by CSIRO.

Project update – June

After some key announcements in early May, over the past month we have been working with community conservation groups and taking the first steps towards finding a joint venture development partner.

Following the decision regarding Amendment 86, we commenced an Expressions of Interest process where we asked for responses from suitably qualified development partners to work with us to deliver a new benchmark in sustainable urban development at Ginninderra.

Expressions of Interest to join CSIRO as a Joint Venture Partner closed on May 23 and we are currently undertaking an evaluation process before shortlisting ahead of a formal tender process.

As part of CSIRO’s commitment to the conservation and restoration of natural values on the Ginninderra property, we have been working actively with the Ginninderra Catchment Group’s grasslands restoration project.

Recently we joined the Ginninderra Catchment Group, Landcare groups, the Rural Fire Service, community experts and volunteers to conduct autumn burning of five experimental sites across the Ginninderra property.

The findings of this community-driven project will provide the scientific evidence base to inform best-practice future management of native grasslands at Ginninderra.

As part of our ongoing engagement activities, CSIRO hosted a site visit with member groups of the Conservation Council last week. This was attended by representatives from the Friends of Grasslands, Ginninderra Catchment Group, and Conservation Council’s Biodiversity Working Group.

CSIRO remains committed to working with all key stakeholders and an event is being organised to update the community and to continue our conversations in the second half of July. More details on this will be made available in the coming weeks.

Exploring Ginninderra’s past, present and future

After more than half a century of dedicated scientific research, CSIRO’s Ginninderra Field Station is entering a new phase. Planning and engagement has commenced to deliver a new benchmark in liveable, sustainable and resilient urban development.

The Ginninderra Field Station was established in 1958 as a site for plant and agricultural research. This was in anticipation of the closure of the Dickson Experiment Station to make way for urban development in that area, which eventually occurred in 1962.

As with the Dickson site, the Ginninderra Field Station has now been surrounded by urban development and is no longer optimal for CSIRO’s agricultural research. In 2011 CSIRO started considering options for Ginninderra’s future use.

Rather than simply sell the property, CSIRO saw Ginninderra as a great opportunity to bring its research together to make a difference, not only for local residents and the ACT, but for other Australian cities, people, industry and the environment.

The sustainable urban development of Ginninderra presents an opportunity for positive social, environmental and economic impact for the ACT and Australia, while generating revenue for the reinvestment into CSIRO innovation and research infrastructure.

In December 2012, CSIRO sought advice from the National Capital Authority about the correct process for seeking an amendment to the National Capital Plan. Through this, a long-term vision to deliver a new benchmark in sustainable urban development has arisen.

It’s a vision that has emerged through engagement with CSIRO’s science capability, undertaking environmental and heritage investigations, and initial conversations with the community, and one that will continue to evolve and bring lasting benefits.

CSIRO staff first met with ACT Government officials in July 2014 and have met regularly since then to discuss the possibilities for the potential development of the Ginninderra Field Station for urban use.

These meetings confirmed that the site presented an opportunity for greenfield development, which has been supported by the NCA’s response to the key issues considered as part of Amendment 86: ‘The CSIRO Ginninderra site presents an opportunity for greenfield development that can make use of existing infrastructure and services, and provides a more suitable alternative to cater for the growth of the city than other greenfield sites.’

CSIRO’s engagement with community groups, nearby residents and industry associations began in August 2015, coinciding with the land’s inclusion as part of Amendment 86.

This first round of engagement with the local community in September 2015 included three drop-in sessions at Gold Creek, Evatt and Charnwood and involved more than 220 people.  This is only the beginning, as CSIRO aims to involve more of these people and groups in the conversation about how we can design and work together for a liveable, sustainable and resilient urban area.

On 5 May 2016, classification of the Ginninderra Field Station to ‘Urban’ as part of the National Capital Plan was approved. This decision paved the way for CSIRO to seek Expressions of Interest (EOI) for a suitable development partner.

Following the closing of the EOI on May 23, CSIRO is evaluating and shortlisting suitably qualified developers, ahead of a Request for Proposal process later in the year.

CSIRO is excited about the opportunity to continue to work with the community, government, research partners, and other stakeholders, to create something unique at Ginninderra.

CSIRO is also committed to continuing the discussions with ACT Government agencies to harmonise with future planning goals and aspirations.

Future steps for the Ginninderra project include a site visit with conservation groups and workshop in June, community forum in July, additional community meetings in early 2017, as well as planning, approvals and detailed design in 2018. The earliest that any development could commence on the site is in 2019.

Bold green vision for Ginninderra future

Over the past few years a vision has been emerging for what a sustainable urban development backed by science and innovation could be like.

Our vision is to restore and improve our natural environment while setting a new benchmark for sustainable urban development.

The terms ‘benchmark and sustainable’ apply to the extent to which we can maximise and maintain the stream of future environmental, social and economic benefits, that flow from the development and its surrounding natural values.

The aspirations for Ginninderra are closely aligned with many of Australia’s key policy settings and targets namely in areas of national innovation, infrastructure, cities and built environment, energy and climate, water and the economy.

CSIRO is well placed to significantly address these important issues because of our coverage of relevant research areas and our capacity to draw on all of these and engage the right collaborators and partners.

We are looking to provide multiple benefits through combining a diversity of housing, community and recreational facilities together with some retail and commercial opportunities, all integrated with the restoration, conservation and management of the landscape and its important natural and heritage values such as the endangered Box Gum Grassy Woodlands.

We are absolutely committed to the management and restoration at Ginninderra of areas of threatened vegetation types and species that are protected by ACT or Commonwealth legislation.

Protection of trees regulated and administered by the Tree Protection Act 2005 is an essential component and CSIRO is developing guidelines that extend beyond its regulatory obligations to ensure their preservation.

This commitment has extended to comprehensive environmental studies that sees approximately 130ha of the site largely protected by legislation and a further 80ha that CSIRO has identified should be managed to protect ecological and heritage values.

Ginninderra residents and other water and energy users will draw benefits from the efficient and sensitive management and use of water and the leading-edge energy efficiency and renewable energy opportunities that we are exploring for the site.

We want to contribute to the evolution of urban areas from being ‘consumer and polluter’ to being ‘energy and water efficient’ and ‘environment protectors’.

We want to help solve the issue of affordable housing, particularly for those in the lower 40 per cent of incomes.

Encouraged by the ideas and feedback generated at our recent gathering of experts – The Affordable Housing Think Tank – we are firmly committed to providing real and lasting affordable housing options, among the property mix at Ginninderra. This will extend well beyond the asking price for moving into the neighbourhood, to various other aspects that affect the cost of living including energy, water and transport.

These topics and others including urban food growing, waste minimisation, recycling and reuse have regularly been raised in our community conversations and we will continue to explore these in future planning together with our joint venture partner.

We are aspiring to urban planning and design that can promote such features, encourage social interactions and connections and maintain an accessible open space network.

CSIRO is committed to keep building this vision with the community and to plan the development with and for the community. There are many steps and stages in front of us before any development occurs and we want to work with the community throughout.

We see community innovation and opportunities for ‘citizen science’ as fundamental components in the creation and future success of this venture.

Citizen science and community activity is already underway and helping to deliver our environmental commitments at five sites across our Ginninderra property, led by the Ginninderra Catchment Group, Landcare member groups and some of its 500 volunteers. This group is extending its work with autumn burning to recover and restore native grasslands in the Ginninderra catchment.

This and other community-driven work will provide valuable insights on how best to restore and conserve areas of the endangered White Box-Yellow Box-Blakely’s Red Gum Grassy Woodland and Derived Native Grassland located on the site.

CSIRO is committed to remaining involved and achieving the exemplar in sustainable urban development.

The reason we are seeking a joint venture development partner is because we want to be closely involved with Ginninderra – firstly, to ensure that we can achieve these conservation, sustainability, liveability and affordability goals. Beyond that we want to realise knowledge and innovation from this development that can be applied more broadly for benefit in the ACT, Australia and beyond.

Beating the heat at Ginninderra

We’ve all experienced the cool relief of seeking respite from a hot day under a shady tree. Recent studies have shown that tree cover plays a large part in combating the urban heat island effect.

Canberra is hot and getting hotter. Temperatures in the ACT have been increasing since about 1950.

Canberra sweltered though 10 consecutive days of 30-degree plus temperatures in early March, providing our hottest start to autumn on record.

This warming trend is set to continue, with recent projections of Canberra’s future climate indicating that temperatures are likely to rise further, resulting in more hot days and fewer cold nights.

This is exacerbated by the Urban Heat Island effect, where cities tend to trap and store heat during the day, staying hotter for longer than the surrounding countryside during the night.

To understand patterns of urban heat across Canberra, researchers in CSIRO Land & Water have used satellite thermal imagery to estimate land surface temperatures and map their distribution.

We recently tested this at Ginninderra Field Station, which yielded some very interesting results.

Dr Matt Beaty, a Senior Experimental Scientist in CSIRO Land & Water said, “As with other cities around Australia, there is a strong relationship between vegetation and land surface temperatures.”

“Newer suburbs, and industrial areas in Canberra with little vegetation cover, are typically much hotter during summer than older suburbs with established tree cover providing dense shade.”

The availability of water is also important. Not just to support healthy vegetation, but to drive the processes of evaporation and transpiration that provide cooling benefits in addition to tree shade.

CSIRO’s urban heat mapping for Canberra has been featured by the ACT Government in their draft ACT Climate Change Adaptation Strategy which is open for public consultation until 3 April 2016.

“There is a lot to be learnt from this urban heat mapping work that is relevant to the proposed urban development of the Ginninderra site and how we adapt our cities to climate change,” said Dr Beaty.

CSIRO heat mapping for the northern part of Canberra (shown below) identifies that during a hot summer day established suburbs are cooler than the Ginninderra site and surrounding countryside.

“This is due to the influence of suburban gardens and associated irrigation, which tends to result in cooler land surfaces than bare cultivated soils and dry sheep paddocks.”

20162203

The coolest parts of the Ginninderra site are the waterways and areas with existing tree cover.

“What this means is that large trees, irrigated grass and water will need to be a key feature of the design of any potential future urban development to combat the Urban Heat Island effect through the provision of shade and to drive the cooling benefits of evapotranspiration,” Beaty said.

Based on site investigations so far, approximately 150 hectares of the land on the Ginninderra site is unable to be developed due to its topography, heritage and ecological values, and is envisaged to form an open space network of connected recreational and conservation areas. This idea of ‘fingers of green’ through the site was reflected in the draft concept presented to the community last year.

But it’s not all about trees, other strategies for adapting our cities to increasing urban heat include the use of light-coloured construction materials in our buildings and paved surfaces. Light coloured surfaces reflect incoming solar radiation, reducing the amount of heat that is trapped in our cities.

Jacqui Meyers, another Senior Experimental Scientist in CSIRO Land & Water has undertaken research on the impact of climate change on the heating and cooling energy costs of a typical Canberra home.  This research is also cited in the ACT Government’s draft ACT Climate Change Adaptation Strategy.

“The energy required to heat a typical Canberra home in 2070 may be one-third lower, but energy for cooling could more than double,” Myers said.

“An integrated response to urban heat is required, which includes a focus on climate-wise buildings, planning provisions that provide space for trees to shade buildings and pedestrians, and open space networks that support healthy vegetation and waterways to deliver further cooling benefits.”

Overall, there are many opportunities for science to inform the planning and design of the proposed urban development of the Ginninderra site. More tree cover is good for addressing the urban heat island effect, but would also provide many other social and economic benefits.

Protecting and restoring our woodlands

Box-Gum Grassy Woodland wildflowers.

If you walk across the northern end of the Ginninderra Field Station in spring and spot an array of yellow and purple wildflowers with gum trees towering overhead, you have come across an area of Box-Gum Grassy Woodlands.

These woodlands once covered large swathes of mid to lower slopes and landscapes across the ACT, Victoria, NSW and southern QLD. Across this region, only 10 per cent of the woodlands remain, with only about five per cent of those remaining in good condition. The picture is slightly better in the ACT, with an estimated 25 per cent of the original woodland remaining and in good condition.

Distribution of Box-Gum Grassy Woodlands.

Distribution of Box-Gum Grassy Woodlands.

The Box-Gum Grassy Woodlands have been in decline since the 1800s due to grazing from sheep and cattle. They were cleared to make way for agriculture, rural and urban developments.

Existing woodlands and grasslands are now protected under both national and state legislation, to guard against further degradation of these unique ecological systems.

The woodlands are typically made up of three layers: the overstory, which in the ACT consists of Yellow Box, Apple Box and Blakely’s Red gum trees; a patchy shrub layer; and a ground layer of native grasses and wildflowers. However, where the trees have been removed and just the ground layer remains, they are then described as ‘derived native grasslands.’

It’s this ground layer that’s critical to the ecology, according to CSIRO ecologist Jacqui Stol.

“When you look at the landscape most people only notice the trees, but the diversity is mostly in the ground layer. Typically, there can be up to 60 species of native wildflowers, orchids, lilies and a diverse range of amazing local plants at a very high quality site,” she said.

At Ginninderra, studies so far indicate there are approximately 114 hectares of Box-Gum Grassy Woodlands on the site of varying quality, including areas where trees have been cleared (derived native grassland). This includes 34 hectares of treed areas in high condition, mostly in the less-developed, northern end of the site, as well as 44 hectares of low quality grassland.

The woodlands at Ginninderra don’t exist in isolation, and are part of a broader ecological system. They link to other nearby woodland areas such as at Mulligan’s Flat, Goorooyarroo, Hall and north-west of Casey and Moncrieff.

“The way we think about how we conserve these sites is within a big landscape matrix,” said Jacqui.

“Ginninderra is part of that bigger picture, and a really important part of the landscape, and how the whole ecology functions.”

How to manage, protect and rehabilitate the patches of Box-Gum Grassy Woodlands is an important consideration in Ginninderra’s potential as a site for future sustainable urban development.

A team of CSIRO ecologists from across Australia met in November 2015 to investigate the site and discuss plans for the protection and improvement of the native ecology. They will continue to be involved in the discussions regarding Ginninderra and are well placed to apply best practice in ecological management.

The team hopes local conservation groups and future residents will be able to contribute to maintaining and improving these woodlands.

CSIRO’s significant expertise in Box-Gum Grassy Woodlands is on display in a comprehensive guide (linked below) for land managers that was recently published by Jacqui Stol and Suzanne Prober.

Measures such as reintroducing tree and shrub species where they’ve been removed could be implemented to help restore the Ginninderra woodlands.

The reintroduction of ground layer species to areas currently of low quality could return those bright purple and yellow wildflowers to more parts of the Ginninderra landscape.

Aspiring for best practice at Ginninderra

As we welcome in 2016, some of the Ginninderra project team have been enjoying a holiday break while others are working hard to scope the vision and potential for a liveable, sustainable and resilient urban development at Ginninderra.

A team of CSIRO researchers, and experts in their fields, gathered in Canberra late in 2015 to discuss the areas of research, technology and innovation that could be included in the Ginninderra venture.

“The workshop produced a lot of ideas and energy about specific science and innovation that we could integrate if the project gets the go ahead,” said science leader Mr Guy Barnett.

“We have some exciting research knowledge and technologies that can contribute to a best practice urban development and we are now working those ideas into a consolidated vision.”

We look forward to revealing these ideas and seeking your input as the project progresses. Stay tuned.

As the vision continues to emerge, the process of seeking reclassification of the Ginninderra Field Station to ‘Urban Area’ also continues.

As mentioned in our last newsletter, we are still following through the processes that govern land reclassification in the ACT.

In the meantime, we’re continuing environmental, heritage and other studies to ensure we have a thorough understanding of the site and needs of a future residential community.

 

Canberra’s hidden reserve

The Ginninderra Field Station was established in 1958 as a site for agricultural research in anticipation of the closure of the Dickson Experiment Station to make way for urban development in that area, which eventually occurred in 1962.

The Ginninderra site is located in the northern area of ACT, surrounded by the suburbs of Gungahlin, Hall and Nicholls to the north, Giralang to the east, and Evatt, Spence and Fraser to the south.

While nearby residents know more, it’s an area many people have driven past every day and never realised what lay within.

Behind the unassuming ridges and rows of vegetation lies 701 hectares of grassy open space with 80 hectares of irrigated, arable land. The quality soil and water availability on the site has provided excellent opportunities to support CSIRO’s agricultural research effort.

There are three houses, a machinery shed, a workshop, a barn, shearing sheds and some scientific equipment and approximately 5,000 sheep on the property.

Australia is famous for its beautiful natural environment which is reflected throughout the site. A mixture of native grasses, Scribbly Gum woodland, Box-Gum woodland, Eucalypts and pines create the greenscape of the site.

A natural drainage system, Halls Creek, separates the upper and lower areas of the site. Surrounded by ridges and hills there are amazing views across to Belconnen Town Centre, Telstra Tower and the Brindabella’s from the highest points of the site.

Canberra is known for its ability to incorporate green spaces into the city. The future of the site will embody this, retaining green spaces, open reserves, and natural vegetation. Sitting within the north-eastern end of site lie two very special trees, Canberra’s oldest oaks. This unique part of the landscape will be preserved throughout the development.

The site is also home to native, endangered species including the Golden Sun Moth and Box-Gum woodland. Protecting the plants and creatures that call the Ginninderra lands home is integral to this project. Opportunities to improve the quality of woodlands and create natural reserves will arise throughout the course of the project.

A number of Aboriginal heritage locations have been identified on the site. When European settlement took place in the area homesteads were set up near the Ginninderra property. Nearby heritage listed sites include the Charnwood Homestead, the Palmerville (Ginninderra) Homestead and the Ginninderra Police Station. These sites are all important in better understanding Canberra’s early history and will be respected throughout the project.

CSIRO in Canberra: from agriculture to space

Dickson farm

Aerial view of Dickson while it was CSIRO farmland.

 

CSIRO’s presence in Canberra is almost as old as Canberra itself, with just 14 years separating the establishment of Canberra and the creation of our national science body.

Since these early beginnings, Canberra has been a critical part of CSIRO’s research in agriculture and the natural sciences.

CSIRO’S Black Mountain offices opened in 1927, with the Department of Entomology moving into its own building in 1934. The Australian National Herbarium was also established during the 1930s.

The first site for agricultural research in Canberra was a site at Duntroon Farm, which later became Canberra Airport. A story in The Canberra Times in May 1931 said the costs of operating the farm would be covered by a £6,000 per annum contribution from the Empire Marketing Board, and that:

“Special attention is to be paid to investigations of wheat resistance and diseases, while a special section will be set aside for testing new grasses and forage plants to be introduced from abroad.”

This research site shifted from Duntroon to the Dickson Experiment Station in 1940, and experiments into crop and pasture trials continued here. Scientists also looked at how land could be used productively for livestock and crop farming, and housed a large flock of merino and Border Leicester sheep.

CSIRO’s history in Canberra is about more than agriculture, even though this has been a key focus. In 1965 the Canberra Deep Space Communication Complex opened at Tidbinbilla, and has worked with NASA on space exploration missions ever since. For nearly 60 years, the Gungahlin Homestead property at Crace was used for CSIRO’s Sustainable Ecosystems research program.

As urban development began to encroach on the Dickson farm, it was time for the field state to be moved once again. CSIRO acquired the 701 acre land for the Ginninderra Experiment Station in 1958, moving all research there by 1962.

The Dickson area turned out to be much-needed land for urban development, as the ACT population almost doubled from 55,000 to over 90,000 in the five years between 1960 and 1965.

Photos from the time show the rapid pace of development in Dickson and the surrounding suburbs once this land close to the centre of Canberra was repurposed.

Meanwhile, the Ginninderra site over the years has provided space for multiple research projects, including testing varieties of crop seeds, animal farming and other agricultural experiments.

The site has contributed to Australian science including the development of BarleyMax and dual purpose wheats, crop and pasture improvement, sustainable farming, plant breeding and the effects of climate changes on crop production and soil carbon.

Once again, the city of Canberra has grown up around a CSIRO research site. Neighbouring suburbs include Hall and Nicholls to the north, the Belconnen suburb of Giralang to the east, and Evatt, Spence and Fraser to the south.

The story of CSIRO’s agriculture research in Canberra continues with the creation of the National Agricultural and Environmental Sciences Precinct, a $190 million investment bringing together research partners at CSIRO’s foundation site at Black Mountain. This initiative will bring together researchers from all over the world to tackle some of the world’s most pressing challenges in plant and environmental sciences.

Seizing new opportunities

For nearly 100 years, CSIRO has driven scientific innovation in Australia. Since it was established in 1926, CSIRO has built on its initial mandate to carry out scientific research in farming, mining and manufacturing.

CSIRO has been in Canberra since 1927, and currently holds seven sites and properties in the ACT. One of these is the Ginninderra Field Station, which has been used for agricultural research for over 50 years.

The city of Canberra has grown up around the site, with suburbs surrounding nearly all sides of the property, which has led the CSIRO explore the site’s future urban development opportunities.

Exploring the site’s future urban potential also offers the opportunity for CSIRO to reinvest in its infrastructure to make sure it can continue carrying out world-class science.

CSIRO holds an extensive property portfolio across Australia and internationally. Property holdings
are regularly reviewed through an ongoing strategic review processes to identify sites that are underutilised and opportunities to reinvest in CSIRO’s infrastructure to continue delivering world-class science.

Agricultural research sites in Canberra have already shifted multiple times to accommodate urban development.

CSIRO Agriculture Director, Dr John Manners, recalls;

“CSIRO has used the Ginninderra Field Station since 1958. Prior to that we had field facilities where the current airport is located and also where the Dickson shops are located now. Part of this site has actually already been rezoned and used for urban development in Crace.”

The facilities at Ginninderra, he says, are aging and need renewing. Given much of the land at Ginninderra is underutilised, moving agricultural research to another location means the new space can be used efficiently and incorporate new technology into CSIRO’s research.

“The Ginninderra field station occupies about 700 hectares of land. A lot of that land at the moment is underutilised in our research, so if we start a new site for experimental research we can optimise our use of the land,” says Manners.
