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_ID,parentLocationID,

census_no,censusNumber,"Brad: Assigned by SALVIAS. 1 for first plot, then 2, 3, etc. I can't recall if we even have repeat censuses in SALVIAS. Probably not."

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:

-----"

subplot,plotName,

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."

ind_id,,Brad: OMIT

tag1,tag/_alt/1,"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."

x_position,relativePlotX,"Brad: These are important, fundamental values of many tree plots"

y_position,relativePlotY,Brad: See comment above for x_position

coll_number,catalogNumber/_alt/1,Brad: Map instead as for voucher_string

collector_code,,Brad: OMIT

coll_lastname,recordedBy.surName,"Brad: This is the collector of a separate specimen which vouchers this tree or species. I worry that vouchers are not properly accommodated in VegX. Again, we need to check with Nick."

coll_firstname,recordedBy.givenName,Brad: See comment above

fam_status,,Brad: OMIT. This will be determined later by using TNRS.

family,family,

cf_aff,verbatimIdentificationQualifier,"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."

comments,,Brad: OMIT

habit,habit,"Brad: This is growth form (tree, shrub, herb, etc.). It is an observation of a trait."

cover_percent,coverPercent,

intercept_cm,volumeCanopy,"Brad: This is an aggregate observation. Used in line-intercept methodology only, describes the point along centerline at which an individual intercepts the center line of the plot. Used to determin relative abundance."

stem_tag1,tag/_alt/2,"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."

stem_height_m,height/_alt/1,"Brad: Same as for height, but applies to individuals stems, not trees. Rare."

stem_height_first_branch_m,heightFirstBranch,"Brad: Same as for ht_first_branch_m, but applies to individuals stems, not trees. Rare."
