ATTRIBUTES

Field	Name	Definition	Unit	Code
1	Year	Year
2	Experiment	Cedar Creek Experiment number
3	Observation_ID	The unique identifier of each phenophase status record
4	Site_ID	The unique identifier of the site at which the status record was made
5	Site_Name	The user-defined name of the site at which the status record was made
6	Latitude	The latitude of the site at which the status record was made	degree
7	Longitude	The longitude of the site at which the status record was made	degree
8	Elevation_in_Meters	The elevation in meters of the site at which the status record was made	meter
9	State	The U.S. state or territory, Mexican state or Canadian province in which the site is located
10	Species_ID	The unique identifier of the species for which the status record was made
11	Genus	The taxonomic genus of the organism for which the status record was made. Taxonomy follows that in the Integrated Taxonomic Information System.
12	Species	The taxonomic species of the organism for which the status record was made. Taxonomy follows that in the Integrated Taxonomic Information System
13	Common_Name	The common name of the species for which the status record was made. Common names for plants follow those in the USDA PLANTS Database
14	Kingdom	The taxonomic kingdom of the organism for which the status record was made.
15	Individual_ID	The unique identifier of the individual plant or the animal species at a site for which the status record was made
16	Phenophase_ID	The unique identifier of the phenophase for which the status record was made. Note that there can be several names and definitions for a given phenophase as they vary between datasets and can change over time within datasets. All definitions lumped under the same Phenophase_ID are considered equivalent for the purposes of general phenological analysis.
17	Phenophase_Description	The descriptive title of the phenophase for which the status record was made. This is the overarching title of the phenophase defined by Phenophase_ID, and may include several different names and definitions , as these vary between datasets and can change over time within datasets.
18	Observation_Date	The date the status observation was made in the field
19	Day_of_Year	The day of year, ranging from 1 to 366, that the status observation was made in the field.	day
20	Phenophase_Status	The status (i.e. presence or absence) of the phenophase at the time the observation was made in the field.		1=yes the phenophase is occurring, 0=no the phenophase is not occurring, -1=not certain whether the phenophase is occurring
21	Intensity_Category_ID	The unique identifier of the intensity category assigned to the phenophase for this species at the time the status observation was made in the field. Intensity measures allow reporting of the degree to which a phenophase is expressed.
22	Intensity_Value	The value reported in response to the intensity category question assigned to the phenophase for this species at the time the status observation was made in the field.
