CorMan and Cormorant counts in the western Palearctic

CorMan is a new initiative taken by the European Commission. One of the main goals of this new initiative is to collaborate with the Cormorant Research Group in order to assess the number and distribution of great cormorants in Europe during breeding and winter. The aim of the joint cormorant count project Cormorant Counts in the western Palearctic is to organise a pan-European census of breeding colonies in 2012 and a census of winter roosts in January 2013 (see materials and links below). The new initiative CorMan also has the aim of developing a website (platform) under DG Environment. The website is available through this link. The main aim of the Platform is to disseminate information about cormorants, cormorant numbers, management and conflicts related to cormorants, fish, fisheries and aquaculture. The Platform will be extended and more material will be added during 2012 and 2013. Contacts between CorMan and relevant stakeholder groups has been established through a Stakeholders’ Liaison Group.

News

By June 2013 national overviews of the colony census will be published in a technical
Wetlands International / Aarhus University report

In July 2013 a summary of the results of the breeding count (2012) and roost count (2013) will be published on the EU Cormorant Platform

There are 2-3 Area Coordinators (ACs) for each major area of Europe and countries further east. People willing to join the counts are welcome to contact the ACs or directly inform their National Coordinator by compiling the form available here
