At low tide, if you are very still, you can see crabs grazing on algae and debris. About 10 species of crab are found on Ash Island, the most striking being the purple-clawed semaphore crab and the red-fingered marsh crab. Look for footprints in the mud—what has been looking for food here? Fish and prawns Schools of tiny juvenile fish live in the shelter of mangroves; they swim into the mangrove and saltmarsh areas with the incoming tide. Look out for them in the tidal creeks and shallow pools. Species caught in the Hunter include: sea mullet, luderick, school prawns, flathead, tailor, bream and goby. Saltmarshes Saltmarshes grow landward of mangroves in areas where tidal flushing is less frequent. Common saltmarsh plants are samphire, salt couch, arrowgrass and salt rush. Debris trapped in saltmarsh areas is broken down by bacteria, worms and crabs forming a rich compost that washes back into the mangroves where it becomes fish food. Written in concrete Scattered throughout this landscape are structures that hint of the island’s more recent, European past. Milham’s farmhouse, grain silos and concrete slabs of dairies indicate past farming pursuits. The schoolmaster’s house (now Kooragang Wetlands Information Centre) indicates that a sizeable community once lived here. Mangroves Mangroves grow where tidal flushing occurs twice a day. The tidal movement helps oxygenate the water-logged soils. Grey mangroves grow throughout the Hunter estuary’s intertidal zone aided by ‘snorkels’ or breathing roots called pneumatophores. A second, less common, river mangrove grows in the higher areas of the intertidal zone and has no pneumatophores. Look out for these occasional multi-stemmed, round- leafed trees. Rainforest remnants Over 200 species of plants existed here in mid-1800. More than half of these formed coastal rainforest. Timber cutting and land clearing have left only isolated patches of original forest. Species found in these remnants include tuckeroo, thorned cockspur, whalebone, plum pine, ash tree and the endangered vine, white cynanchum. As you walk through these remnants watch out for colourful butterflies, snakes and thorny vines, and listen for small birds. WELCOME TO KOORAGANG WETLANDS Freshwater wetlands and frogs Although most of the wetland areas here are saltwater, freshwater wetlands form where ground is higher or tidal flows have been blocked by roads. These are home to a unique set of plants and animals including ribbon weed and typha, and 15 species of frog including the endangered green and golden bellfrog.

CHANGE: THE ONE CONSTANT IN AN ESTUARY Change is a feature of all living systems, and in an estuarine situation, such as Kooragang Wetlands, changes are even more pronounced. Change can be fast or gradual, a result of natural processes or human activity. Tidal changes are the most frequent. Twice a day the water level rises bringing with it nutrients, small fish and other creatures seeking food and shelter amongst the mangroves and saltmarshes. Twice a day the water level falls exposing mudflats on which crabs and wader birds feed. Slow natural changes such as a combination of erosion, land subsidence and sea level change has allowed mangrove seedlings to establish themselves in areas previously dominated by saltmarsh. Over time, as an area becomes more, or less, salty, a different community of plants (and animals dependent on those plants) is favoured. Man-made changes: Most of the recent change on Ash Island has been the result of human activity. Blocking of tidal creeks has led to mangrove and saltmarsh losses and the flourishing of sheoaks and freshwater vegetation. As tidal flows are restored, freshwater vegetation will die in the brackish conditions, and mangrove and saltmarsh will once more dominate. On higher ground, land clearing and the introduction of pasture grasses and other weeds have resulted in the loss of native vegetation and the wildlife that depended on it. Various walks enable you to explore the mysteries of the tidal world, glimpse the majesty of once luxuriant rainforest and discover historic ruins that hint of bygone days. Kooragang Wetlands is being restored in a number of ways; return regularly to witness its transformation. Guided walks are conducted at times posted at the Kooragang Wetlands Information Centre or by arrangement (phone 02-4964 9308).

About half these are waterbirds of which 34 species are migratory waders. Thousands of these waders spend from October to April in the estuary. They can sometimes be seen at low tide searching on mudflats and saltmarshes for tiny crustaceans and other mud dwellers. Around April they return to Siberia and northern Asia to breed. Other birds can be seen all year round. White-faced heron NSW FISHERIES TOM KENDALL DAVID BLAGDEN Kooragang Wetlands Information Centre

Kooragang Wetlands:YesterdayPre-European era:For thousands of years Aboriginal peoplehave hunted and gathered food on and around the 20 or so

islands and mudflatsof the Hunter Riverestuary.The variousclans of the Worimiand Awabakalpeoples thrived onabundant fish,shellfish,water birdsand other animals.Coastal rainforestflourished in non-tidal areas of theislands.

Timber-getting era:Within twenty years of European arrival in1797,most valuable timber,such as red cedar and ash,hadbeen removed from the Hunter estuary islands.

‘A remarkably fine place’:Ash Island was granted to A.W.Scott,entrepreneur and keen naturalist in 1827.He grew orangesand established market gardens at Scotts Point.His daughters,Helena and Harriet,recorded and painted the diverse flora andfauna of the island.Visiting naturalists,the Goulds and LudwigLeichhardt,enthused about ‘the beauty of nature’and the‘great number of plants’found there.

Farming era:Ash Island was subdivided in the1860s and landwas cleared and drained for further agriculture.There were 17dairies with 55 families from the early to mid 1900s,and aschool was established.But floods,culminating in a two-metredeluge in 1955,made farming increasingly difficult.

Industrial era:Port and industrial activities started in thesouth-east of the estuary in the late 1800s.By the1960s mostof the estuary islands had been joined to form onelandmass—named Kooragang Island in 1968—which wasintended as one large industrial complex.Farms on thewestern—Ash Island—end were resumed for this purpose,butdue to flooding and other concerns industrialisation has notoccurred in this area.

Environmental era:In the1980s the north-eastern third ofKooragang Island was set aside as part of Kooragang NatureReserve and in 1984 declared a Ramsar site (‘wetland ofinternational importance’).Kooragang Nature Reserve is nowpart of the Hunter Estuary Wetlands.

EXPLORING KOORAGANGWETLANDS

How to get there

By car, bike or on footKooragang Wetlands (Ash Island site) is accessed via Ash Island

bridge, 100 m east of McDonalds on the Pacific Highway at

Kooragang Wetlands:Vision for the futureThe return of sustainable natural abundance to the Hunterestuary

➢ well managed, productive and appreciated wetlands➢ a great place to visit for fishing, birdwatching, history,

walking and cycling ➢ a thriving, productive, sustainable City Farm in harmony

with its wetland surrounds➢ increased areas of lush vegetation attracting birds and

other animals native to coastal rainforest

Kooragang Wetlands:TodayThe problem:There havebeen losses of over 1300haof fisheries and otherwildlife habitat in theHunter River estuary overthe past 200 years.

The response:TheKooragang WetlandRehabilitation Project(KWRP) was initiated in 1993to restore and createfisheries and other wildlifehabitat in the Hunter Riverestuary while creatingopportunities for research,education and recreation.

The place:Three sites wereidentified as suitable areas:Ash Island (780 ha),Tomago(800 ha) (no public access)and Stockton high tide roost(10 ha).Together these sitesmake up KooragangWetlands.

Ash Island is the mostaccessible and active site ofKooragang Wetlands.

In low-lying areas thefisheries habitat is being restored by removing obstructions towater flow.

Permanent and solar-powered electric fencing has beenerected to protect all river banks and waterways from cattle.

In non-tidal areas more than 120,000 trees and shrubs ofspecies that once grew on the island have been planted since1995.These are helping to protect riverbanks and expand areasof coastal rainforest,home of an endangered vine.Birds andbutterflies are increasingly attracted to these areas.

Researchis being used to guide the rehabilitation of KooragangWetlands and monitor its success.

Education:Guided tours on a variety of subjects are available byappointment for school and community groups and individuals.

Kooragang City FarmKooragang City Farm isinvestigating andpromoting agriculturaltechniques that areproductive,yet inharmony withsurrounding wetlands,on 150 ha of the AshIsland site.

City Farm incorporates:➢fencing to protect all waterways and river frontage

➢the restoration of vegetation along waterways

➢mixed eucalypt forestry

➢cattle grazing (using holistic management) to achievemore beef from less land under hoof

➢bush food,vegetable,and herb gardens

➢citrus,stone and tropical fruit tree trials

At the north-west corner of City Farm is Riverside Park,featuring a jetty and recreational area for picnicking andfishing.Further east lies the ruins of Milham’s farmhouseand dairy,built in the 1860s (see separate brochure).

Volunteers

Volunteers play a large partin helping to restore thevegetation of Ash Island.Since 1995 more than120,000 trees and shrubshave been planted.If youhave time,come along toone of our volunteers days.All are welcome.

Tree planting:3rd Sunday ofevery month except December,9.30 am start,barbecuelunch provided.(N.B.November,January and February,8.30am start,morning tea provided).Bush regeneration:every Wednesday,8 am to 2 pm.City Farm Community Garden:every Tuesday and Friday,8am to 2 pm.
