City Nature Challenge 2025 Wien

Last updated: 2025-05-07

Species in bold are ones for which the given observer has one or more research-grade observations.

If only one person has RG observations of a species, but other people have observations which need ID, the number of needs-ID observers are indicated in parentheses. For example:

Centranthus ruber (Red Valerian)
means the observer is the only one to have observed that species, but none of their observations are research grade.
Cercopis arcuata
means the observer is the only one to have observed that species, and one or more of those observations are research grade.
Polydesmus complanatus (Flat-backed Millipede) (1)
means that the observer and one other person have observed that species, but only the listed observer has research-grade observations of it.
