Porters Creek Wetlands
Location and spatial dimensions
Porters Creek Wetland ( PCW) is located in the NSW Central Coast. The wetland covers an area of 5 sq km and is the Central coast's largest freshwater wetland. For a small wetland it has a high biodiversity, including several endangered species. Within its 50 sq. km catchment, PCW plays a vital role in filtering runoff that drains through the wetland, into the Wyong River and then into Tuggerah Lake. Increasing pressure from human activities, particularly rapid urbanisation, in the Porters Creek Wetland catchment is threatening the integrity and functioning of the wetland. Management strategies are needed to increase the resilience and sustainability of the ecosystem while protecting its natural heritage (biodiversity) and utility value (environmental services). Ecologically sustainable development in the catchment is a key to the successful management of PCW.
Porters Creek Catchment
Porters Creek Catchment is the area of land that supplies water to Porters Creek Wetland. It stretches from Buttonderry in the northwest to Woongarah and Kanwal in the east and Wyong River in the south. It has three main floodplains that bring water to the wetland from:
· the east - Warnervale catchment (18 km2)
· the north - Buttonderry Creek - Mountain Road catchment (15 km2)
· the north-west - Jilliby, Hue Hue Creek, Warnervale Business Park catchment (10km2)
Darkinjung Land
Porters Creek Wetland is Darkinjung Country.
'The traditional boundaries of Darkinjung land extend from the Hawkesbury River in the south, Lake Macquarie in the north, the McDonald River and Wollombi up to Mt Yengo in the west and the Pacific Ocean in the East'.
