Flowering period

The months of the beginning and end of flowering across Europe are given. The data were compiled from Kaplan et al. 2019, French Flora database and Guarino et al. 2019. For each species, we provide a maximal flowering range across available sources.

Continentality

Continentality degree is derived from the position of species distribution range on the gradient from oceanic Western Europe to continental Middle Asia. The concept and data were taken from Berg et al. (2017), who revised and corrected a previous system of indicator values for continentality developed by Ellenberg et al. (1991). Higher values on the ordinal scale from 1 to 9 indicate species distributed in more continental areas. The species that extend over more than four regions assigned to different continentality classes as defined by Jäger (1968) are considered to be indifferent unless their lower continentality border is located in the regions assigned to continentality class 2 or higher.

Continentality amplitude

The concept and data were taken from Berg et al. (2017), who revised and corrected a previous system of indicator values for continentality developed by Ellenberg et al. (1991). Continentality degree is derived from the position of species distribution range on the gradient from oceanic Western Europe (class 1) to continental Middle Asia (class 10). Consequently, continentality amplitude corresponds to the number of phytogeographic continental classes where given species is distributed.
