CRO maps available again

Corrected Regional Occurrence (CRO) maps have been updated with the data from 2015 and the 50 new species and are already available in the EBP viewer.

Modelling the spatial and temporal dynamics of bird distributions is one of the main but challenging objectives of the EBP project. This work is underway and, therefore, it has to be stressed that CRO maps are still very preliminary.


CRO maps make use of a complex set of spatial and temporal aggregation and smoothing procedures to account for differences in observational effort and reporting activity of the observers.
