It seems to me that if ESRP were to propose a working definition of community it should be something like "An inclusive set of people benefiting from final ecosystem goods and services produced within a defined geographic boundary"
This takes advantage of the recent attempts to create an operational classification system for indicators of final ecosystem goods and services.
This focusses our assessments on valuing the production of services within some manageable boundary (eg. watersheds) while allowing us to derive value from benificiaries outside that boundary. It's a systems minded definition.
