Dear Tim,
Sound's like your looking for indicator species ?
Maybe the indicspecies packages suites your needs.
Dufrêne, M and P. Legendre. 1997. Species assemblages and indicator
species: the need for a flexible assymetrical approach. Ecological
Monographs 67: 345 - 366.
De Cáceres, M., P. Legendre, and M. Moretti, 2010. Improving indicator
species analysis by combining groups of sites. Oikos 119: 1674 -1684.
Cheers,
Eduard

Or can I easily identify which species are 'most important' (most abundant?) for defining each of the three groups?
