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."

plot_code,locationName,,

census_date,eventDate,,"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

FROM ""SALVIAS-CSV"".organisms

WHERE subplot IS NOT NULL AND census_date IS NOT NULL

GROUP BY ""PLOT_ID"", subplot

HAVING count(DISTINCT census_date) > 1

tag1,tag,/_alt/2/_alt/2,"The second tag supercedes the first. The stem tag supercedes the tree tag. Brad: Another type of code, typically a number, used by the original data provider to indicate an individual tree. These are numbers on physical tags attached to the tree. Tag2 Is the same thing, only used if the first tag was lost. Obviously not a good system as it's possible a tree tag could be lost and changed more than once."

cf_aff,identificationQualifier,,"Brad: Not sure where this goes. Indicator of identification uncertainty. 'cf.'=similar to the species listed, 'aff.'=related to the species list, but not the same. You'll need to check with Bob and with Nick where these go in VegX and VegBank."

no_of_individuals,individualCount,,"Brad: This is a count of number of indiiduals for an *aggregate* observation. For VegBank, I'm not sure. Not exactly the same as stemCount. An individual tree could have 3 stems but would still only count as 1. We need to check with Bob on this."

stem_tag1,tag,/_alt/1/_alt/2,"The second tag supercedes the first. The stem tag supercedes the tree tag. Brad: Same as tag1 & tag2, but applied to individual stems. I'm still not clear how to distinguish between methods which tag only individuals trees, and those which tag individual stems."
