Average Recurrence Interval (ARI): the likelihood of occurrence, expressed in terms of the long-term average number of years, between flood events as large as or larger than the design flood event. For example, floods with a discharge as large as or larger than the 100-year ARI flood will occur on average once every 100 years.
Connectivity: the degree to which the landscape facilitates or impedes movement between resource patches; thus, a landscape with high connectivity is one that provides functional connectivity regardless of what it looks like in terms of structural connectivity.
Corridor: a landscape element that connects two or more patches in a relatively unbroken (contiguous) line; thus, a form of structural connectivity.
Disturbance: a temporary change in average environmental conditions that causes a pronounced change in an ecosystem.
Drivers: external forces or conditions that can cause a system to change.
Ecological communities: are unique and naturally occuring groups of plants and animals. Their presence can be determined by factors such as soil type, position in the landscape, climate and water availability.
Ecological Vegetation Classes (EVC’s): are a component of a vegetation classification system. They are groupings of vegetation communities based on floristic, structural, and ecological features.
Fragmented: refers to the absence or the underdevelopment of connections between the society and the groupings of some members of that society on the lines of a common culture, nationality, race, language, occupation, religion, income level, or other common interests.
Habitat: a place suitable for survival and/or reproduction of a particular plant or animal species; Note that structural connectivity could be used by a species for dispersal, but this is not considered to be habitat.
Identity: the essential nature of a system (an individual, an ecosystem, a society) based on the way it functions and on its defining structural characteristics.
Intact: untouched, especially by anything that harms, defiles, or the like; uninjured; whole; undefiled; left complete or entire; not damaged.
Long term objectives: long term (20-30 year) goals for the system components of the Catchment -people, land, water and biodiversity. These objectives are found in the sub-strategies of the Goulburn Broken CMA. Achieving these objectives will contribute to the Vision being realised. In some instances these objectives may be related to known (or assumed) thresholds and tipping points.
Management measures: specific activities at an asset or SES scale aligned to the strategic priorities. Management measures will be found in the relevant sub-strategies and investment plans as they are operational in nature.
RCS Strategic objectives: shorter term, high level goals that outline what needs to be achieved in a 6 year timeframe in response to the drivers of change that have been identified as being able to push landscape system variables over thresholds into alternative states. Achieving strategic objectives contributes to maintaining or achieving desired states.
RCS Strategic priorities: of the many areas of that could be focused on to achieve the strategic objectives, these are the areas of action currently considered most critical. Strategic priorities relating to the categories of biodiversity, land, people and water can also be found in the relevant sub-strategies. These priorities have a six year timeframe.
Relictual: a group of animals or plants that exist as a remnant of a formerly widely distributed group in an environment different from that in which it originated.
Resilience: the amount of change a system can undergo based on (its capacity to absorb disturbance) while retaining the same function, structure and feedbacks.
Social-ecological systems: linked systems of people and nature, taking into account cultural, political, social, economic, ecological and technological components.
State: commonly refers to either the present condition of a system or entity, or to a governed entity (such as a country) or sub-entity.
System: the set of state variables together with the interactions amongst them, and the processes and mechanisms that govern these interactions.
Thresholds: levels in underlying controlling variables of a system where feedbacks to the rest of the system change.
Tipping points: is the event of a previously rare phenomenon becoming rapidly and dramatically more common.
Vision: an aspirational statement outlining how the Catchment will look in 50 years’ time.
