Wallis Lake Estuary Management Plan
11 Glossary
Aesthetic:
Acid Sulfate Soil:
Aquaculture:
Biodiversity:
A theory as to what is beautiful or appealing. In this plan the aesthetic amenity of the
estuary is a combination of scenic attributes and water quality.
‘Soils containing materials that are rich in sulfides, primarily pyrite, which when oxidised
produce acidity in excess of the sediments capacity to neutralise the acidity resulting in
soils of pH 4 or less’ (LNCCMB, 2002).
‘Farming of aquatic organisms including fish, molluscs, crustaceans and aquatic plants’
(LNCCMB, 2002).
‘The variety of life forms, the different plants, animals and microorganisms, the genes they
contain and the ecosystems they form’ (LNCCMB, 2002).
Catchment: ‘The area of land drained by a river and its tributaries’ (LNCCMB, 2002).
Commercial:
Cultural:
Denitrification:
Ecosystem:
Pertaining to business related activity resulting in profit.
In reference to values pertaining to the Aboriginal community including language, songs,
art, customs, beliefs and environmental knowledge; and physical attributes such as
artefacts, scar trees, carvings and burial and ceremonial places.
The microbial reduction of nitrate to di-nitrogen gas.
‘Communities of organisms and their physical environment interacting as a unit’ (LNCCMB,
2002).
Effluent: ‘Human and animal waste in a liquid form’ (LNCCMB, 2002).
Environmental:
Estuary:
Eutrophication:
Faecal coliforms:
Relating to the natural world including the physical, chemical and biological components
and the way in which they interact.
‘The tidal portions of river mouths, bays and coastal lagoons, irrespective of whether they
are dominated by hypersaline, marine or fresh water conditions’ (Hutchings & Collett
1977). Included in this definition are inter-tidal wetlands, where water levels can vary in
response to the tidal levels of the adjacent waterway, together with perched freshwater
swamps, as well as coastal lagoons that are intermittently connected to the ocean.
The collapse of a marine, estuarine or aquatic ecosystem due to excessive algal blooms,
accumulation of nutrients in sediments, and low levels of dissolved oxygen.
‘Bacteria which inhabits the intestines of humans and other animals, and are present in
faeces. Their presence in water quality testing indicates faecal contamination of water and
that other more serious pathogens may also be present’ (LNCCMB, 2002).
