Aquifer - An inclined sub-surface porous rock layer between two non-porous layers, containing a substantial amount of water.

Biodiversity – Is the variety of all life forms, the different plants and animals and micro-organisms, the genes they contain and the ecosystems of which they form part.

Bioregions – Bioregions are elements of a new natural framework based on the patterns of ecological characteristics in the landscape or seascapes, allowing us to recognise and respond to biodiversity values. Eight bioregions have been identified for the Glenelg-Hopkins region. Eighty-one bioregions have been identified for Australia.

Capacity Building – Increasing the potential to gain maximum results/benefits for the community.

Catchment - The natural boundary of the area where all surface water drains to a common point. Ridges form the boundaries of catchments.

Community – The body of people living within the Catchment boundaries.

Community Engagement – To consult the community or get them aware and involved in a particular event, activity or project.

Corridor – Corridors are linear habitats that differ from a more extensive, surrounding matrix. Frequently they link one or more patches of habitat in the landscape and may be a pathway for animal and bird movement.

Crown Land - Land which, or is deemed to be, unalienated land of the Crown.

Direct Seeding – The process of planting the seed straight into the ground as opposed to planting tubestock.

Discharge – An emission or flow of a substance from an object (ie. river)

Ecological Vegetation Class (EVC) - The components of a vegetation classification system. They are groupings of vegetation communities based on floristic, structural and ecological features.

Ecosystem - All the organisms in a particular area, functioning together to form a dynamic system, which vary greatly in the complexity and the species present.

Fauna - A general term for animals (including reptiles, birds, marsupials, and fish).

Flora - A general term for plants of a particular area or time.

Framework – The supporting structure/basic system.

Geographic Information System (GIS) - A system which holds spatially referenced data which can be classified, overlaid, analysed and presented in map, tabular or graphic form.

Groundwater - All subsurface water occupying the pores and crevices of rock and soil.

Habitat - The natural home of a plant or animal.

Heath Vegetation - Community dominated mainly by shrubs, generally less than 2 metres in height. Common in coastal areas or on sites with low nutrient levels.

Heritage River Area - Land that is a heritage river area under section 5 of the Heritage Rivers Act 1992. Each area of land described in part of Schedule 1 of the Act is a heritage river under the name specified in that part.

Integrated Catchment Management – Management covering the entirety of flora, fauna and water as a whole.

Implementation Committee – The group that puts a decision, plan, or contract into effect.

Land Capability - A term used to describe the capability of a Land System to support a particular use or activity without being degraded.

Land Use - Current or intended statutory use or tenure of land. It is the primary level of public land classification in Victoria.

Macroinvertebrate – Animals without backbones that are visible to the naked eye; they include insects, worms, snails, shrimps, water fleas etc.

Macrophyte – Literally “big plant”, used to describe water plants other than microscopic algae, sometimes apparently used to exclude filamentous algae or even all algae except for members of the Characeae.

Native Forest - Any local indigenous community, the dominant species of which are trees and containing throughout its growth the complement of native species and habitats normally associated with that forest type or having the potential to develop these characteristics. It excludes plantations of native species and previously logged native forest.

Noxious Weed - A weed declared by legislation to be harmful (especially for agriculture) and which must therefore be eradicated from all land and must not be propagated or planted.

Nutrients (Waterways) - Includes nitrogen and phosphorus contained in waterways.

Plan – A method or procedure for doing something; a design or scheme.

Recharge – To charge again or be recharged.

Remnant Vegetation – Remnant vegetation describes native vegetation occurring within fragmented landscapes. Remnants are generally small to medium sized patches of vegetation surrounded by highly modified land, such as cropping or grazing lands. Remnants often exist as patches of trees and shrubs, however, the term also describes fragmented native ecosystems or a product of existing land-uses and management practices. Remnant vegetation is therefore a stand of native vegetation that reflects current and past management practices rather than a relic from pre-European settlement.

Riparian – Riparian land is any land which adjoins or directly influences a body of water and includes land immediately alongside small creeks and rivers, gullies and dips that sometimes run with surface water, areas surrounding lakes and wetlands on river floodplains which interact with the river in times of flood.

Salinity – An increase in the salt content of soil (caused by bad land management, poor irrigation methods etc.), resulting in progressive infertility.

Shelterbelt – A plantation of trees or shrubs designed to give shelter to livestock or vegetation.

Stakeholder – A person or group that has an interest in, or concern for, a certain activity.

Strategy – A long-term plan or policy.

Sustainable – Something that can endure or is able to be maintained for long periods of time.

Tubestock – Pre-grown trees or native shrubs.

Turbidity - A measure of how 'dirty' the water is in a stream or lake. The higher the turbidity the 'dirtier' the water.

Understorey - The layer of vegetation that grows below the canopy formed by the tallest trees in the forest.

Water Basin - A geographical unit, defined by the physical boundaries of its watershed, it provides a natural division for assessing the environmental impact of human activities.

Watertable – The level of water below which the ground is saturated with water.

Watershed - A natural boundary separating the headwaters of different watercourses or river systems.

Weed - Plants that invade native vegetation, usually affecting the regeneration and survival of the indigenous flora and fauna.

Wetlands – Wetlands include natural lakes, swamps, estuaries, rivers, streams, shallow marine areas (including beaches and rocky shores) and artificial wetlands such as reservoirs, sewerage farms, irrigated agricultural land and farm dams.

Wildlife Corridor - A strip of vegetation or forest of varying width reserved from harvesting, to facilitate fauna movement including gene movement between patches of forest of varying ages and stages of development.ACRONYMS:
