Data set 1.

Column label	Column description
occurrenceID	An identifier for the Occurrence (as opposed to a particular digital record of the occurrence). In the absence of a persistent global unique identifier, construct one from a combination of identifiers in the record that will most closely make the occurrenceID globally unique. In this dataset, specimens use the ID number from its holding facilty; observations have their own unique observation ID.
eventDate	The date-time or interval during which an Event occurred. We present eventDate in ISO 8601 format. In some cases, day, month, or year data is missing.
year	The four-digit year in which the Event occurred, according to the Common Era Calendar.
locality	The specific description of the place. Less specific geographic information can be provided in other geographic terms (stateProvince, county). This term may contain information modified from the original to correct perceived errors or standardize the description.
stateProvince	The name of the next smaller administrative region than country (state, province, canton, department, region, etc.) in which the locality occurs.
county	The full, unabbreviated name of the next smaller administrative region than stateProvince (county) in which the locality occurs.
decimalLatitude	The geographic latitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Note the coordinates are very pricise, as they describe the very center of a polygon that encompasses all uncertainty associated with the locality (see coordinateUncertaintyInMeters).
decimalLongitude	The geographic longitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Note the coordinates are very pricise, as they describe the very center of a polygon that encompasses all uncertainty associated with the locality (see coordinateUncertaintyInMeters).
coordinateUncertaintyInMeters	The horizontal distance (in meters) from the given decimalLatitude and decimalLongitude describing the smallest circle containing the whole of the Location.
geodeticDatum	The ellipsoid, geodetic datum, or spatial reference system (SRS) upon which the geographic coordinates given in decimalLatitude and decimalLongitude as based. Data presented here in WGS84.
coordinatePrecision	A decimal representation of the precision of the coordinates given in the decimalLatitude and decimalLongitude.
georeferencedBy	A list (concatenated and separated) of names of people, groups, or organizations who determined the georeference (spatial representation) for the Location. In this case, K.R. Burgio, georeferenced all sightings but 4.
georeferencedDate	The date on which the Location was georeferenced in ISO 8601 format.
georeferenceSources	A list (concatenated and separated) of maps, gazetteers, or other resources used to georeference the Location, described specifically enough to allow anyone in the future to use the same resources.
georeferenceProtocol	A description or reference to the methods used to determine the spatial footprint, coordinates, and uncertainties. We used the GBIF best practices guidelines established by Chapman & Wieczorek (2006).
georeferenceRemarks	Notes or comments about the spatial description determination, explaining assumptions made in addition or opposition to the those formalized in the method referred to in georeferenceProtocol.
institutionCode	The name (or acronym) in use by the institution having custody of the object(s) or information referred to in the record. We include a list of abbreviation codes with the full name of the instutition in a separate .txt file with the dataset.
basisOfRecord	The specific nature of the data record.
recordedBy	A list (concatenated and separated) of names of people, groups, or organizations responsible for recording the original Occurrence. The primary collector or observer, especially one who applies a personal identifier (recordNumber), should be listed first.
associatedReferences	A list (concatenated and separated) of identifiers (publication, bibliographic reference, global unique identifier, URI) of literature associated with the Occurrence.
infraspecificEpithet	The name of the lowest or terminal infraspecific epithet. Here, we we relate subspecies identification as recorded on the specimen tag, if known.
eventRemarks	Comments or notes about the Event.
dynamicProperties	Assessment of quality of the sighting, based on expert opinion (see associated referenced for discussion of each sighting). The categories are: 1) "validity=Specimen" which indicates that a specimen exists, or did exist at one time. 2) "validity=Confirmed observation” which indicates that the observation is largely considered valid by either McKinley and/or Snyder. 3) “validity=Unconfirmed” is an observation that for one reason or another is considered controversial. 4) “vality=Likely invalid” is an observation or specimen that may be a result of fraud or mislabeling, pending independent verification.
collectionCode	The name, acronym, coden, or initialism identifying the collection or data set from which the record was derived.
catalogNumber	An identifier (preferably unique) for the record within the data set or collection.
license	A legal document giving official permission to do something with the resource.
rightsHolder	A person or organization owning or managing rights over the resource.
accessRights	Information about who can access the resource or an indication of its security status. Access Rights may include information regarding access or restrictions based on privacy, security, or other policies.
bibliographicCitation	A bibliographic reference for the resource as a statement indicating how this record should be cited (attributed) when used. Recommended practice is to include sufficient bibliographic detail to identify the resource as unambiguously as possible.
references	A related resource that is referenced, cited, or otherwise pointed to by the described resource.
