1. The area has to be a square, but does not have to be the precise outline of an existing Ordnance Survey grid square (i.e. you can shift a bit to avoid motorways!)
2. All species must be within the square, or deemed to be probably in the square (but birds flying miles away don't count).
3. The species must be detected between 1st Jan 2013 and 31st Dec 2013, although identifications can continue afterwards if necessary.
4. For the purposes of the species total, only species-level identifications count. Aggregates of any defined grouping at greater than species level, where no species within that grouping have been identified, should be recorded though and count in the case of a tie!
5. The participant does not have to fully identify each species themselves; help is allowed, so long as the participant is engaged in the identification process and understands why the species is what it is (i.e. no sending buckets of flies to the local museum...)
6. Evidence-only records (mole hills, galls, leaf-miners, bat detections etc) do not count unless the organism itself is seen or heard. Such records should of course still be written down.
7. Dead things count so long as they clearly died within the square (e.g. pitfall traps).
8. Garden plants are allowable if they have spread under their own steam more than 2 metres from the nearest garden boundary.
9. Trees that have clearly been planted deliberately, for whatever reason, are not countable; however, it has to be accepted that it may be impossible to tell for older native trees and in such cases the species can be included.
10. All records should be submitted to the relevant local or national recording society or local record centre, as appropriate.
What have I missed? Also, quite happy to have some of these debated...
