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:
- high value Box Gum Grassy Woodlands and Derived Native Grasslands on the north of the site
- areas of Derived Native Grasslands where studies have recorded the presence of Golden Sun Moth and Striped Legless Lizard
- a Box Gum Grassy Woodland and Scribbly Gum Woodland area surrounding a nesting site of the Little Eagle
- an area of Box Gum Grassy Woodland adjacent to Owen Dixon Drive
- regulated trees and cultural heritage features
Other areas or features earmarked by CSIRO for protection include:
- the corridor (riparian zone) along Halls Creek and drainage lines
- areas of Scribbly Gum Woodland and Box Gum Grassy Woodlands that contribute important environmental values but are not technically protected under legislation
- important buffer zones and areas that add habitat and wildlife connectivity to protected areas, both on the site and in adjacent areas
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.

Topography of Ginninderra and surrounds

The National Capital Plan (NCP) sets out the broad planning principles and policies for Canberra and the Territory, and ensures that they are planned and developed in accordance with their national significance.
One of the NCP’s objectives is to protect the undeveloped hill tops and open spaces which divide and give form to Canberra’s urban areas. People within the community have commented that changes at Ginninderra may put the protection of the hill tops at risk.
Looking at the Ginninderra site in the context of its surroundings, however, we don’t view future urban use as contrary to the National Capital Plan’s objective to protect the undeveloped hill tops. This is because of a number of topographical features.
The site’s topography is an important factor in determining water corridors (flood zones) and visual aspects that can be enhanced with vegetation and link visually to surrounding areas.
When set among the surrounding high points of Mount Rogers Reserve and Harcourt Hill, the site has a relatively low level of elevation with no significant ridgelines. You can see this in the map above.
There are however some higher parts on the site which provide views of different parts of Canberra. At an elevation of 70m across the site, the highest point is located at the northern end of the site (Block 1609). This high point provides views northwest towards rural lots of NSW.
The second highest point is located just to the south of Kuringa Drive (Block 1545). From this point you can see extensive views to the southeast of Canberra, including Black Mountain, Mt Majura and Mt Ainslie. Halls Creek and Ginninderra Creek provide the low points within the site.
These inherent environmental features will shape future development at Ginninderra. Based on studies so far, we have already identified approximately 150 hectares of the land to be kept aside for ecological values and open space.
