Phenology data set of plants and birds and other taxonomic groups, as well as agrarian activities and abiotic phenomena from Latvia, 1970-2018

A data set of phenological observations of plants, birds, as well as agrarian activities and abiotic phenomena from Latvia, 1970-2018 is presented. The data include limited number of observations of insects, amphibians, mammals, mushrooms, mollusks and fishes as well. The data was collected by voluntary observers (citizen scientists) and published as paper based yearly bulletins.

Station: name of the observation station

Year: year of observation

Season: season of observation as indicated in the primary publication

Species: English name of the species observed or description of phenomena observed in case of abiotic occurrences

Species Latin: Latine name of the species observed

Taxonomic_group: taxonomic group of the species observed or grouping of non-biological phases (“Abiotic” for meteorological phenomena and “Agrarian” for agrarian activities)

Phenophase: description of phenological phase observed

BBCH: attributed BBCH code for phenological phase observed, where applicable

Date: date of the first observation of the phase

DoY: day of the year of the first observation of the phase

Implausible: flag indicating of the reported date of phenological phase is highly implausible (TRUE) or realistic (FALSE)

Wrong_order: flag indicating if the order of the reported phases at a given station and year is not realistic (TRUE) or realistic (FALSE)
