Hi,

I had a look at the questionnaire. It asks for a ranking of listed 
values/ecological services "from the monetary point of view". So, the decision 
to rank by money or profit has already been made (I wonder by whom?). The 
questionnaire rather shows that there is no generally accepted objective 
approach for putting a price on ecosystem services. The price will depend on 
the demand for a certain service and the demand will differ from place to place 
and from time to time. I don't think I can contribute as an ecologist to this 
economic ranking. Rather, I will use the extra space in the questionnaire to 
point out that the ranking should also be done according to other scales than 
economic value.
