Just 45 minutes south of Canberra, this unique reserve is home to some of Australia's most threatened temperate ecosystems.
As around 300 hectares of this 1,328 hectare property had been cleared for farming, Scottsdale is often a hub of volunteer activity, restoring these cleared areas so they can help support some of the threatened species occurring in the natural parts of the reserve.
Scottsdale protects endangered grassy box woodlands and temperate grasslands. It also harbours many rare birds, animals, fish and reptiles.
Wrapped around Scottsdale's northern and western flanks is the Murrumbidgee River, which cascades over natural rock weirs and through deep tree-fringed pools. The Upper Murrumbidgee Demonstration Reach is a partnership supporting the recovery of native fish in the river.
What Scottsdale protects
Scottsdale's home to a remnant of Australia's last ice age, the Silver-leafed Mountain Gum. Adapted to a time when this part of the world was much drier and colder, just 10 populations of this little mallee tree are thought to exist in Australia, and it's vulnerable to extinction. The reserve also protects:
- Animals: Rosenberg's Monitor (vulnerable in NSW), Speckled Warbler (vulnerable in NSW), Peregrine Falcon, Brown Treecreeper (vulnerable in NSW).
- Plants: Currawang (spearwood), Curved Rice Flower, Button Wrinklewort, Silky Swainson-pea.
- Vegetation communities: Yellow-box grassy woodland (nationally critically endangered), Scribbly Gum-black Cypress-pine Forest, Tablelands Frost Hollow Grassy Woodlands, Southern Tablelands Natural Temperate Grassland (nationally endangered).
What we’re doing
Restoring an entire ecosystem is a tricky business, but at Scottsdale we hope to do just that by helping natural regeneration along, by replanting key species of the precious yellow box woodland.
A project aiming to restore 300 hectares of woodland is being carried out by Greening Australia – and we've jointly funded it with the Australian Government.
How do we create an environment that favours native plants when the soil has a long history of fertiliser, grazing and cultivation? African Lovegrass is a major headache. One successful strategy we've used has been removing the top 10cm of nutrient-enriched topsoil. We then direct seed with a mix of native trees and shrubs.
Relocating the Striped Legless Lizard
With 1 in 15 Australian reptiles at risk of extinction, we've translocated and reintroduced the Striped Legless Lizard to Scottsdale. We rescued these nationally-threatened lizards from two development sites in northern Canberra.
Upper Murrumbidgee Demonstration Reach (UMDR)
The UMDR has been established to demonstrate ways of supporting the recovery of native fish. Amongst its projects are carp control research and willow reduction measures.
Carp are one of the world's most invasive species and research we're involved in has the potential to inform targeted carp removal on a much broader scale.
Not much is known about their movements and where they aggregate in the context of this upland riverine system. The project involves tagging fish and tracking their movements with acoustic telemetry. They'll also be lured, trapped and removed from a section of the river to learn more about their population structure.
Reducing the impact of willow trees
Willow infestation is a major issue for native fish habitats – it can block out native plants, alter stream flows, cause flooding and reduce water quality. The UMDR works to control young emerging willows with volunteers in kayaks cutting back and removing the plants before they can establish.
Scottsdale is within the traditional lands of the Ngunawal people and is very close to Lake George, where the Ngunawal creator being (Budjabulya) is thought to reside. It was also part of a trade route with the neighbouring Yuin people, and home to the Ngunawal clan totem, the Platypus (mulagun).
We've worked with the Ngunawal to carry out cultural heritage surveys, unearthing artefacts, including stone axes and tool-making materials, so we can ensure important sites are protected.
The purchase of Scottsdale was made possible with funds from the Commonwealth’s National Reserve System Program, as well as our generous supporters.
