impacts on other components of the system.
It is therefore essential to approach the management of Brisbane Water on a ecosystem
basis, looking at management action not just in terms of its direct effects, but also the
indirect effects that are possible through ecosystem linkages. The important subsets of,
or influences on, Brisbane Water ecosystem are:
- Water quality interactions. Interactions occur between water coming from the
catchment, creeks, tributaries and various stormwater outlets and water from the
sea, both with different chemical and physical attributes, meeting and mixing to
form the waters of Brisbane Water.
- Water biota interactions. Are the interactions between water quality and the living
populations of plants and animals in Brisbane Water. They form a complex chain
from lower to higher organisms that can easily be disturbed by changes in water
quality.
- Shoreline ecosystems. Interactions occur within ecosystems at or near the
shorelines; a richly productive environment because of the shallow warm water and
diversity of habitat. These ecosystems are under pressure because of heavy
human use of the shorelines for recreation, tourism and commercial development.
- Wetland ecosystems. Coastal wetlands are extensive throughout Brisbane Water
with its fringing vegetation communities. There is considerable overlap between
wetland and shoreline systems. Many shoreline interactions are also important in
coastal wetlands; recreation salinity, habitat and water quality management. In
addition, there are the important considerations of water supply to the fringing
coastal wetlands, catchment salinity and problems of waste disposal to coastal
wetlands.
- Development. The changes imposed on the estuarine environment to make it
more suitable for a wide range of human requirements, displace vegetation and
habitat, introduce effluent into water systems, change run-off patterns and affect
landscape values.
A detailed list of the objectives, management guidelines and actions is outlined below with
details on timing for implementation, responsibility for action and source of funding.
