Welcome to “Narma Kullarck” Boardwalk & Bird Hide

Narma Kullarck Boardwalk at twilight

The first thing everyone experiences as they enter the floating boardwalk after the winter rain is that sensation of walking on water – feeling the gentle swell and sway of the wetlands lapping around the boardwalk. And they carry this feeling in their spirit as they connect with nature and feed their souls on its beauty.

The floating pontoons afford a surreal view – tucked away in a thicket and emerging with the bird hide on Bibra Lake. Together, the boardwalk and bird hide, are shaped like the long neck and oblong shell (respectively) of our endearing oblong turtle. And the aerial view shows off the turtle’s form spectacularly. As a symbol, this is apt. Oblong turtles are native inhabitants here.

The boardwalk and bird hide have been named – “Narma Kullarck” – an Aboriginal Nyoongar phrase that means “family place”. And it is truly that. A place for people from all walks of life and all corners of community to intermingle and connect.

A place of meditation and exploration, where you can delve into the thriving environment and ecosystem, as well as find your roots, develop and strengthen your bond with nature. A celebration of our culture of inclusivity and openness. And an ode to the rich and vibrant Aboriginal heritage, the people on whose land the structure stands.

Staying True to Aboriginal Values

The North Lake “Coolbellup” and Bibra Lake “Walliabup” sites within the Beeliar Regional Park have longstanding cultural and historical ties to the Aboriginal people.

Evidence collected from these sites has included more than 2000 artefacts made of clay, glass, quartz and fossilised sedimentary rock called “chert”. Of these fossiliferous chert dates back to the last ice age, more than 6000 years ago, when it could have been found on land that has since become the seabed. This evidence suggests that the sites are at least 5000 years old! To put this in context, the sites are older than the great pyramids.

The Narma Kullarck Boardwalk and Bird Hide have been constructed on Aboriginal heritage land. In order to maintain the sanctity of the ancient connection, in the initial planning phases, support was sought from the Aboriginal Community and the Department of Indigenous Affairs (DIA).

The City of Cockburn initiated a consultation process that included inviting native title applicants and other senior members of the Aboriginal Community to share their views on the design, location and construction of the boardwalk and bird hide. Anthropological and archaeological reports were also commissioned in order to establish constraints.

 

Developing the Initial Plans

In 2008, the City of Cockburn engaged consultants to develop a plan for the development and management of recreational and conservation facilities at Bibra Lake. The council adopted the plan in early 2010. The plan was also subjected to full community consultation including consultation with the Wetlands Centre Cockburn, prior to adoption.

Very early on in the process, plans were altered to avoid sinking piles into the lakebed as this was considered unacceptable to Aboriginal beliefs and values. However, DIA gave permission to construct a floating boardwalk and a design for floating pontoon structures using prefabricated systems was approved.

It was critical that the pontoons did not restrict fauna movement in any way. To meet this special requirement, a central access channel was designed to run underneath the entire length of the boardwalk. Numerous access points have also been incorporated for wildlife to move under the boards seamlessly.

The native paperbark wetland environment posed further challenges to the design, with poor site accessibility due to thick vegetation and its propensity for seasonal inundation. This meant that the contractors working on the project would need to be specialised with intimate knowledge of the wetland environment and an ability to work under varying conditions.

 

Project Specifics, Facts and Figures

Jarrah timber has been used for the decking. The timber decking is better (compared to GRP open grating) because it is more in keeping with the aesthetic surroundings of Bibra Lake. And the bird hide has been created out of recycled timber.

The 70-metre-long floating boardwalk has been built as close to the ground as possible and is designed to lift with the water when the area floods. There aren’t any visually intrusive handrails, and at the same time, the boardwalk is wide and stable. At 2 metres wide it allows for easy access for wheelchairs and prams.

The bird hide includes viewing slots at both heights for children and adults on each of the three walls and there is ample bench seating everywhere – inside as well as outside.

There are wooden steps at a few places along the way that make working in the surrounding wetland possible for volunteers and staff during planting season. And there are metal steps at the bird hide that lead to the water’s edge for school children who come to visit the Centre during the school holidays and need to collect samples for their study.

The whole project cost a little under $650,000 to complete.

 

Opening Ceremony

The Narma Kullarck boardwalk and bird hide were officially opened on the 13th of October 2012, at a short mid-morning ceremony. The beautiful structure is a labour of love and hard work, staying true to every expectation.

As a family place, it reflects the hopes and dreams of Aboriginal Elder and Chairperson of the City of Cockburn’s Aboriginal Reference Group, Revd. Sealin Garlett. Traditionally, the site has served as a place for Aboriginal families to meet, gather and exchange knowledge. And it was his hope that the new boardwalk and bird hide would continue to serve the community in similar ways.

Together with Revd. Sealin Garlett, the City of Cockburn Mayor, Mr. Logan Howlett cut the ribbon. In our case (and appropriately so), it was a braid of red, yellow and black threads woven with gum leaves in place of the ribbon.

The boardwalk and bird hide are incredibly popular with the public who come here to appreciate nature, contemplate and rejuvenate.  The vegetation is thriving. And it isn’t hard to spot some wildlife – turtles, frogs, birds and bandicoots, casually enjoying Narma Kullarck too.

Wetlands & Water. Rehabilitation & Conservation.

A bird's eye view of a wetland and its evirons

Watching our wetlands transform is an awe-inspiring experience. We may see change with seasons. Or, through circulation of life-giving water and rainfall. The transformation is evident in the way their vegetation thrives, blooms and blossoms. Within the catchments where delicate ecosystems flourish as diverse organisms interact with each other and with the environment. And, in the cacophony of bird and animal sounds that fills the air with every favourable shift.

Water brings out the unique character of our wetlands.

Not all wetlands are waterlogged all the time, some depend on groundwater and others on surface water flows and still others are coastal wetlands that are revived by the seas. They may be seasonally, intermittently or permanently drenched. They may be saline or freshwater. They may be still or flowing. No matter what the nature of the wetland, water plays a central role.

 

Wetlands – A Living System

Wetlands support complex and diverse bionetworks. They shelter and sustain wildlife. Here landforms and soils are created, nutrients are naturally recycled and waterways are filtered and cleaned.

The specialized wetlands vegetation helps in stabilizing the soil, cleaning the water and providing resources and habitat. From upland vegetation – shrubs and trees, to fringing vegetation – sedges, rushes and paperbark trees, and floating and submerged aquatic plant-life – adequate vegetation is fundamental to wetland health.

Leaves or branches that fall from overhanging trees and shrubs are broken down by microbes, bacteria and fungi. These, in turn, become food for larger animals within the food web. And wetlands ecosystems are sustained by the functions of these tiny organisms.

 

Wetlands and Water

Wetlands that see water once every few years, or those that are permanently waterlogged, every wetland ecology is unique. Species of plants and animals have evolved to suit these very specific conditions of dampness, salinity and nutritional availability.

Urban and rural encroachment have posed some serious threats to the wetland ecology.

Paved roads and concrete structures mean that a greater volume of water now finds its way into the wetlands. Road run-off often contains oil, heavy metals and various other substances that leach into the wetlands. Fertilizers, pesticides and chemicals from nearby home gardens or agricultural fields too seep into the groundwater, from where they travel to the wetlands.

Environmental degradation has caused drastic changes in the water cycle. Wetlands now face prolonged inundation or drying and a constant change in the physical, chemical and biological composition of water entering the wetlands. This imbalance adversely impacts native species that are unable to survive or cope. Further, loss of native vegetation has the potential to disrupt and collapse the delicate wetlands food web.

 

Wetlands Rehabilitation

Our wetlands are an important and essential resource. They provide us with a natural filtration system, cleaning our waterways of harmful pollutants, absorbing and trapping carbon in the marshy soil, and replenishing our groundwater and underground aquifers. Wetland plants and animals function to strengthen this delicate link between water and wetlands.

They help regulate the climate. They supply food, fibre, fuel and medicinal plants.

Above and beyond the functions they fulfil, wetlands are a source of great beauty. They are gateways to adventure and for “experiencing nature” away from the hustle and bustle of our cities and suburbs. The abundant life they support – from native species to migratory long-distance travellers. The deep interlinkages and connections, and the balance they restore.

Wetlands rehabilitation is, therefore, the single most crucial calling of our time – revegetation, habitat restoration, conservation and protection. An involved community and teamwork. And spreading awareness about their importance.

Water Conservation

Inland freshwater wetlands provide water to over three billion people around the world.

Without our wetlands, the water in our households, industries and farms would have been unusable.

Water conservation is a vital aspect of wetlands rehabilitation work. It involves using and uncovering innovative wetlands management techniques that help control the quality of water within catchments.

Water Sensitive Urban Design Principles, in the context of urban wetlands, protect the wetlands from urban run-off and degradation. Applying these principles ensures that the infrastructure we create does not impact them unfavourably.

Water conservation is also largely dependent on the native plant and animal species, their distribution and propagation. And on our sustained rehabilitation efforts.
