However, it has the important property of uniquely identifying an ""observation"", which is an individual tree, in the case of an individual observation, or a records of a species with an associated count of individuals or measurement of percent cover, in the case of aggregate observations. Not sure where to store this. Main point is that it is not part of the original data, but an auto_increment added later."
