EBBA2 pilot maps

Merops apiaster_Bělka za web

The EBBA2 project is entering the final year of the data collection process. However, we have already gathered some available data and have thus generated pilot maps. These maps were produced for 15 species, showing the occurrence, breeding evidence, abundance and changes in comparison to the first European Breeding Bird Atlas. 

In particular, we produced four different 50×50 km maps showing: occurrence, breeding evidence, abundance and changes in species distribution in comparison to EBBA1.

These maps are now available for the following species:  Great Cormorant (Phalacrocorax carbo), European Shag (Phalacrocorax aristotelis), Northern Harrier (Circus cyaneus), Baillon’s Crake (Porzana pusilla), Eurasian Oystercatcher (Haematopus ostralegus), Common Sandpiper (Actitis hypoleucos), Common Black-headed Gull (Larus ridibundus), Yellow-legged Gull (Larus michahellis), Rose-ringed Parakeet (Psittacula krameri), Eurasian Eagle-owl (Bubo bubo), European Bee-eater (Merops apiaster), Sardinian Warbler (Sylvia melanocephala), Wallcreeper (Tichodroma muraria), Eurasian Blackbird (Turdus merula), Northern Wheatear (Oenanthe oenanthe).

 

Example of the maps for Sardinian warbler, with an additional modelled map of probability of occurrence is presented below.

In addition, we managed to produce the first pilot EBBA2 high resolution map (10×10 km) for the Sardinian Warbler (Sylvia melanocephala) using the preliminary set of standardised data provided by national coordinators in the second data privision and ensemble prediction of seven species distribution models (ANN, BRT, FDA, MARS, RF, GAM and GLM). This first modelled pilot map shows a few inconsistencies with our current knowledge of the species distribution and will be improved with the final data.

All these cartographic data are available at the EBBA2MapViewer, a special tool produced to visualise these and the forthcoming maps of this exciting project.  These maps were produced through already the third data provision request sent to all national coordinators within the EBBA2 scope, and are an updated version for the five species requested in the first pilot data provision. Detailed information on the characteristics of the first pilot data provision is available in Bird Census News 2014: 27.
