[Dr E. Buxbaum]

In Germany, Belgium and the Netherlands there is a school project 
running, were pupils list the plants growing on a place near their school 
and put the information into a data base on the Internet. This data base 
then calculates pointer values acording to ELLENBERG. There was a paper 
on this in the June issue of c't magazine. I can check the bibliographic 
details and the net sites if you are interested.
