Thanks for your detailed response.
I am using cover/abundance so my data is 0,1,2,3,4,5,6,7 (with no scores being above 5).

OK. Got you. So to better frame my question – what my collegues must be doing is using Braye & Curtis for row (site) association/ classification and Kulzynski for Column (species) association/ classification. Im assuming that this is appropriate.
Thanks again I will mull over this and try. I’ll let you know how I go.
