OBSERVATION_ID,individualID,"Brad: Neither is correct; this is just an internal ID for table plotObservations. 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."

census_date,plotEventStartDate,"This is for the subplot, not the organism, as all organisms in a subplot have the same value for it. The following query returns no rows:

-----

SELECT ""PLOT_ID"", subplot, count(DISTINCT census_date) AS census_date_count

GROUP BY ""PLOT_ID"", subplot

HAVING count(DISTINCT census_date) > 1

tag2,previousTag/_alt/1,"Brad: See commend for tag1. Your mapping for tag2 looks correct. Probably both values would go here, only nested, with one superceding the other."

stem_tag2,previousTag/_alt/2,Brad: see above

individual_code,recordNumber,"Brad: Code, if any, used by the data provider to indicate an individual tree. Scope is unknown, although typically this value is unique only within plot, or sometimes only within subplot."
