Isaacs Ridge Nature Reserve

Isaacs Ridge Nature Reserve, part of Canberra Nature Park, is a 387 hectare reserve located in the south-eastern part of Woden Valley, and connecting with Mount Mugga Mugga and Wanniassa Hills nature reserves. The ridge offers great views of urban Canberra.

The reserve supports Yellow Box-Blakley’s Red Gum Grassy Woodland on the eastern slope and provides important breeding and foraging habitat for woodland birds. The threatened Pink-tailed Worm Lizard (Aprasia parapulchella) has been recorded in the reserve and much of the ridge provides suitable habitat.

Cultural Landscape – A continuing connection to country

Aboriginal people lived in and managed the landscape in this region for thousands of years and have maintained a connection to the land to the present day. Generations of Aboriginal people have cared for Country, and have been sustained, physically and spiritually through their relationship with the land, waterways and cosmology.

Traditional Custodians have actively managed the landscape through activities such as ‘fire stick farming’ and selectively cultivating certain plants, which created the landscapes first seen by explorers and pastoral settlers.

Continuation of knowledge

Traditionally, the local Ngunnawal people shared knowledge and responsibility for Caring for Country. Today, this cultural knowledge continues to be passed down to younger generations and has a role to play in the management of ACT reserves. Aboriginal community organisations and the Murumbung Rangers in the ACT Parks and Conservation Service run cultural activities to educate the wider community about the cultural landscape, heritage values and land conservation practices.

Heritage sites

The reserve protects several known Aboriginal heritage sites including stone artefacts, occurring individually and in small scatters on the surface, and it is likely that other as yet unrecorded sites also occur.

These sites are of cultural significance to Traditional Custodians, linking generations of Aboriginal people over time, and they are also of archaeological significance as an important source of information on the history of the reserve and the ACT region.

All Aboriginal places and objects in the ACT are protected under the Heritage Act 2004 and must not be disturbed. Anyone finding an (unregistered) Aboriginal object or place has an obligation to report it to the Heritage Council.

Historic Heritage

The area was part of the Duntroon land holdings of the Campbell Family and also part of the Mugga Mugga Station. During the nineteenth century the land was mostly used for stock grazing.



Vegetation communities and associations

The reserve supports endangered Yellow Box-Blakely’s Red Gum Grassy Woodland and forest on the western facing slope is dominated by Red Stringybark (E. macrorhyncha).

There are three significant stands of the Drooping She-oak (Allocasuarina verticillata) which are a potential food resource for the threatened Glossy Black Cockatoo (Calyptorhynchus lathami).

Plants – Land of diversity

Several plants considered rare in the ACT including Pale Flax Lily (Dianella longifolia) and a small population of the endangered Hoary Sunray (Leucochrysum albicans var. tricolor) have been recorded in the reserve.

Animals – Home to many

The vulnerable Pink-tailed Worm Lizard (Aprasia parapulchella) has been recorded on Isaacs Ridge, and much of the ridge provides suitable habitat. The reserve also provides habitat for threatened and declining woodland birds including Brown Treecreeper (Climacteris picumnus) and Speckled Warbler (Chthonicola sagittata).


Isaacs Ridge/Mount Mugga Mugga ParkCare conducts regular activities such as weeding, tree planting and maintenance, interpretive walks and mapping of rabbit warrens. For further information visit the ParkCare Initiative page.



Isaacs Ridge Nature Reserve is accessible from numerous points in Isaacs.
