Definition and/or background
The following is from Fulton et al 2004a -
...
The index is the sum of the percentage of sessile biota weighted by the estimated ages of the biota and is calculated using the following relationship:
Need to add equation (5.8)
where ai is age class i (in years) and mi is theproportion of defined area covered by individuals of age i. For example, an area 100% covered by 1000-yr old organisms would score 1000, whereas a 100% cover of 1-yr old organisms would score 1. Results can be simply graphed to provide a conceptual view of the status of an ecosystem.

Robustness
The following is from Fulton et al 2004a -
Low, may increase with testing: Limitations are that without ecological data on when different successional states are symptomatic of anthropogenic degradation or natural disturbance it would be hard to interpret. Thus, the uncertainty lies with determining which states are natural and which are human induced. However, since there have been a few major detailed studies into effects of trawling on benthic habitats (e.g. Northern Prawn Trawl Fishery of Northern Australia, Poiner et al. 1998; Grand Banks of Newfoundland, Prena et al. 1999; Gulf of Alaska, Freese et al.1999; Gulf of Maine, Auster et al. 2001; Scotland, Tuck et al.1998), data from these studies could be tested with this index to measure it’s robustness.
