Overview

Nestled between the Porongurup and Stirling Ranges, Twin Creeks is a privately owned conservation reserve – purchased and managed by the Friends of the Porongurup Range.

This is a passionate group of people making a real difference to the conservation of their region, and beyond. Twin Creeks is a crucial part of Ranges Link – a combined community effort to reconnect remaining habitats between the Stirling and Porongurup Ranges National Parks, which in turn is part of the even larger scale Gondwana Link effort.

The Friends of the Porongurup Range group is a wonderful example of a local community-based organisation taking bold steps to protect and manage their local environment.

For the casual visitor, Twin Creeks tells its story around an evolutionary art sculpture in the top corner near Knights Rd.

For the enthusiasts, Twin Creeks has a spectacular diversity of plants and animal life which can be explored via several short walk trails. Bird watchers will find a great range of bird species to there, from small wrens up to the occasional flock of cockatoo.

The Friends of the Porongurup Range take great pride in owning and looking after such a significant conservation reserve. They welcome you warmly to their special place and hope you will enjoy your visit.

There are picnic facilities, BBQs and toilets onsite. Please respect the property and follow the guidelines for entering. Any support you can provide the Friends group is appreciated.

Noongar Boodja 

Twin Creeks sits on Noongar land, and is part of the network of waterways and small valleys between two very culturally significant areas Borong -g urup (Porongurup) and Koi Kyeunu-ruff (Stirling Range).

We understand it would have been an important living and food gathering area, with fresh water coming down the creeks and many different vegetation types yielding different types of food.

All ancestral lands are important to Noongar people and the Friends respect that, and ask visitors to be kind to Boodja (country).

Why Twin Creeks?

Twin Creeks is named for the two creeks which meet on the property and flow to the Kalgan River, which flows into the Oyster Harbour and then out to the sea at Emu Point near Albany.

Twin Creeks is on the plain between the Porongurup and Stirling Ranges, at the heart of one of the most biodiverse areas of the world. It is one of the few remaining protected bush properties in the broad Kalgan valley, which is dominated by agriculture. When farmed it was only ever partially cleared, and is now a mixture of remnant bush, revegetation, and regrowth.

A variety of soil types across the reserve has created a landscape rich in biodiversity – the laterite uplands of Jarrah/Marri to the flooded ironstone lowlands to the granite outcrops and sheoak groves.

When this special property with its significant conservation values came onto the market, the Friends of the Porongurup Range realised that with a new owner it was at risk of being all cleared or subdivided.

This spurred the volunteer, not-for-profit organisation into action. By 2003 they had managed to raise the funds and they purchased the 511ha property.

In doing so, the Friends of the Porongurup Range made history by creating a unique community-privately owned reserve which continues to be restored and managed by the group and is open to visitors.

Twin Creeks is now part of the National Reserve System and there is a conservation covenant on the land, meaning that no matter the future ownership, it cannot be cleared. And now it is also being well managed, regenerated, studied and enjoyed for its intrinsic values.

A place of transitions

From Twin Creeks you can see both Borong-ur (Porongurup Range) and Koi Kyeunu-ruff (Stirling Range).

You’ll notice how different they look, which tells a story of their different geological history.

Twin Creeks lies in the valley between these two places, and so is a transition zone where there is a mixture of all kinds of landforms and soil types: upland laterite, flooded ironstones, deep grey sands and granite outcrops.

Each of these landforms and soil types have their own plant species, some rare and endangered.

The reserve has such a rich diversity of soil types that the habitat can change dramatically over short distances. Heathlands and mallee give way to jarrah and marri trees atop ancient rust-coloured laterite ridges while stands of Porongurup karri and wandoo woodlands dot the reserve.

There are also vast differences in rainfall across the region, dramatically reducing as you travel from south from the Porongurup Range, north to the Stirling Range. Differing amounts of rainfall is also reflected in the diversity of vegetation types, and some of this diversity is there within the Twin Creeks Reserve – from karri to mallee.

Spectacular wildflowers

The diversity of soil types which results in the immense diversity of flora at Twin Creeks means that there will probably be something flowering all year round.

Like everywhere else in south-western Australia the most spectacular flowering display will be in Djilba and Kambarang (August to December).

Results from regular biodiversity surveys of the Porongurup area by the Friends of the Porongurups are available at iNaturalist:

Diversity in soil types creates diversity in vegetation, and the more different kinds of plants and habitat types, the more kinds of animals a place can support.

Nectar loving birds, insects and honey possums are all attracted to Twin Creeks Reserve because of the number of different flowers and habitats.

Twin Creeks is a great place to spot birds, thanks to the open woodlands and low heaths with tracks throughout the reserve. Because there is usually something flowering here, birds are attracted to feed all year around. The freshwater dam attracts waterbirds too, some to drink, and some duck species to nest.

See & Do

Walks

There are five different signposted walk trails around Twin Creeks reserve. All walks are easy to moderate – there are no significant hills, but some sections are rough and uneven. The creek crossing is particularly rocky and uneven, with water flowing in winter and spring and some rock-hopping may be required. The rest of the walks are accessible by prams and wheelchairs, except after heavy rain.

Blue Walk (Lambertia Thickets – Wetlands – Banksia Heath) = 3km loop

Green Walk (Flooded Ironstone Heath – Wandoo Woodlands) = 1.4km one-way, 2.8km return

Yellow Walk (Sheoak-Jarrah/Marri – Mallee – Paperbark = 2.3km one-way, 4.6km return

Orange Walk (Banksia Heath – Melaleuca Heath – Jarrah/Marri) = 5.9km loop

Purple Walk (Mallee regrowth – Jarrah/Marri) = 4.9km loop

Citizen Science

The Friends of Porongurup Range appreciate visitors logging or uploading any interesting animal or plant sightings on iNaturalist while you are visiting the reserve. Upload your sightings at a dedicated page for Twin Creeks.

This helps to build up a database to understand the flora and fauna on the property. Importantly, you don’t need to be an expert or scientist to do this – other people on the iNaturalist site will help you to identify what it is you’re looking at.

All you need is a good photo – check out the website to see what other people have uploaded.

On-ground action

 

Conservation Projects at Twin Creeks includes on-ground activities to rehabilitate the soil and restore native plant species, dieback management, and surveys to monitor changes in conditions, habitat and populations of local fauna.

Bird data is collected to monitor numbers, behaviour and preferred habitat. The surveys are conducted with assistance from Birdlife Australia, CCWA and volunteers.
