This page provides some background and justification for the headings selected to describe each indicator.
...
Indicators can be limited to a certain ecological area depending on the type of data that is required or they can be used across all ecosystem. Many indicators are still being development and their use across all ecosystems is currently in review based on data available and the types of ecosystems that the indicator was initially developed for. This section is intended to highlight any ecosystems that an indicator is not suited to, has not been tested for, or if it is suitable to be used in all ecosystems.
Identified capability
Appropriate definitions required
demonstrable = this indicator definitely shows this by these studies, data sets, etc.
...
In general, a poor rating based on this subjective system did mean an indicator was dropped from further consideration by simulation testing. However, if an indicator has been strongly advocated in the past, is already widely used, or if field work had indicated that it may actually have potential, then it was included (if possible given the form of the model) regardless of rating.

Examples of an indicator in use
These next three section are management oriented and are here to provide examples of how an indicator is used in a system.
Current status and trends
...
Information that could be described in this section includes:
- What was it like in an undisturbed/unexploited system?
...
- How would it be expected to change?
...
- Which direction is the indicator showing a
...
- system is going in
...
- - steady, decreasing or increasing?
...
The trend associated with meeting an operational objective can be a limited or target reference point, trajectory or direction. Target stock use in management plans has a tradition of setting reference points (Jennings 2005). In other fields a reference point can not be made therefore a trajectory or reference direction is used instead. See figure below from Jennings 2005 for an example of points, trajectories and directions. The unexploited, target, precautionary and limit are reference points where as the green arrows are the trajectories or reference directions. These are all measurement of progress of the management performance.
...
- reference points that show an undisturbed or unexploited system.
- limit reference points that show the values of indicators associated with serious or irreversible harm.
- target reference points that show the preferred values of the indicators.
- Precautionary reference points may be used to guarantee a high (preferably specified) probability of avoiding a limit because most indicator values include error.
Management strategies and/or objectives
define a standard set of management objectives?? ie from Indiseas
...
Information that could be described in this section includes:
- Has it been used in a management strategy? if so how?
- What is the relationship to management strategies/ objectives?
- Which of the four specific management objective (adapted from Indiseas) has been used for this indicator?
- Conservations biodiversity -
- Ecosystem stability and resistance to perturbations -
ecosystem - Ecosystem structure and functioning -
resource - Ecosystem structure and functioning -
- Resource potential
has it been used in a management strategy? if so how?
...
- -
Need to add definitions to the above objectives
Stakeholder/public acceptability
Acceptability with stakeholders
- by all stakeholder
- by the public
- understandable to the stakeholders
Associated links
Information that could be described in this section includes:
- Is the indicator understandable to the public? stakeholders?
- Does the public and/or stakeholders need further education about an indicator and how it is used for management objectives?
- What is the acceptability with stakeholders? Answers include:
- It is widely accepted
- There is good public awareness
- There is weak public awareness
- There is no public awareness
- It is unknown
Is more background info is needed for this section?
Associated links
Useful weblink and initiatives for an indicator.
