I would agree with Hannu, but there will be many other like communities that will have different types of survey requirements as well.

What I believe would be worth while would be for a central standard for observations and basic/minimal survey information, with the ability to have small specific extensions for specialised surveys (forestry, marine, fresh water aquatic fish, etc.) that will each have specific requirements.  

As I would see it, the Observation Standard would be the common-denominator fields that could be appended by extra community-specific fields as appropriate.
