Robustness
The following is from Fulton et al 2004a -
Potentially high: has potential as a first-order rapid assessment indicator, which could trigger further investigation. Advantages are that it is “user friendly” for managers and the broader lay and scientific communities. It is also conceptually simple, transportable, easy to teach and relatively inexpensive once the underlying data has been collected. Its disadvantages are that it is very simplistic, requires data from unfished reference areas (which are hard to locate), or from suitable historic data (which may not be available). Second, IBIs must be produced on a case-by-case basis-data and are not broadly applicable. Third, the index could be ambiguous, and for this reason should be interpreted in conjunction with other indicators of community level, such as ABC dominance curves, trophic indicators etc. Lastly, unless the constituent indices are chosen carefully, as an ecological indicator it can be no more “integrated” than single species assessments.
