of urban development applications within Gosford City. This work may also be
applicable to other local government areas. The project is due for completion in
2006.
Mangrove Encroachment into Saltmarshes
This project is addressing the increasing problem of invasion of saltmarshes by
mangroves. This problem is highlighted even further now that this community has
been determined as an Endangered Ecological Community. This research will look
at the factors that facilitate invasion and look at affected areas throughout Gosford
City. This study will be completed in 2005.
Conservation of the Green and Golden Bell Frog Litorea aurea through captive
propagation at The Australian Reptile Park
The Central Coast has two significant sites for the endangered Green and Golden
Bell Frog – North Avoca and Davistown, both of these populations are at risk of
extinction. This project will investigate the Davistown population more thoroughly,
and develop a captive breeding program with the potential to release individuals into
existing populations.
Population and Ecological Research of Long-Nosed Potoroo (Potorous
tridactylus) in Remnant Habitat in Gosford City
The Long-nosed Potoroo is listed as vulnerable at both state and federal levels. This
study will assess the local habitat requirements for this species, gather population
data, gather information on the potential effects of fire locally upon this species, and
recommend strategies for the long term management of this species. The project is
due for completion in 2006.
Investigations of Water Quality and Relationships with Planktonic Distribution
and Abundance in Brisbane Water
This research will assess the variability of phytoplankton and zooplankton throughout
Brisbane Water, and relate these to water quality measures and other variables. The
information generated will be utilised in the Brisbane Water Estuary Process Study,
which is currently in preparation

Mangrove Creek Catchment Biodiversity Projects
Councils'Water & Sewerage Directorate manages the Mangrove Creek catchment area to
protect the Gosford & Wyong Communities water supply. The catchment includes approximately
11 620 hectares of native forests and former farmlands from Kulnera to Mangrove Mountain.
The Mangrove Creek catchment is bounded by Yengo and Dhurug National Parks to the west
with McPherson State Forest and rural industries in the east. The catchment is biologically
diverse, with a fourteen vegetation communities preserving eleven threatened flora and
provides a healthy potential habitat for twelve threatened and ten vulnerable fauna species
(Conacher Travers 2001).
Councils'Water and Sewerage Directorate adopt a holistic approach to catchment management
that includes preserving biodiversity by following legislation, developing community awareness
and implementing strategic projects.
