Follow-up measures

Monitoring of nesting colonies

Objectives and methodology

The objective of the measure is to improve knowledge of the nesting colonies in the Bay of Saint-Brieuc. This monitoring is not intended to replace actions already carried out in the territory, but to complement them in order to refine knowledge of local nesting colonies.

The scientific protocol establishing the technical modalities of field actions was established jointly between Ailes Marines and local stakeholders (Bretagne Vivante, GEOCA, ​​Syndicat Mixte Grand Site Cap d'Erquy Cap Fréhel, and VivArmor). The coordinator of the implementation of monitoring is GEOCA. The 7 Islands site was ruled out after discussions with the LPO because the latter is already particularly well followed and known.

All species of nesting birds are monitored, and more particularly Great Cormorants, Gulls, Storm Petrels, Shearwaters, Alcidae, Black-legged Kittiwakes and Terns.

3 types of monitoring have been identified

Classic follow-ups

From the Scientific Interest Group for Marine Birds (GISOM) for species whose parameters are not or little known.

u

Broad prospecting

To identify possible nesting areas not yet known.

Drone monitoring

Which will make it possible to approach certain species that cannot be approached by traditional means.

This video was taken during monitoring of nesting colonies carried out by Ailes Marines , in May 2020, and produced by VivArmor Nature on the Ilot du Verdelet (drone service provider: Littomatique ). The objective is to carry out a census of the species present on the islet of Verdelet, in order to estimate the number of nesting birds present, as well as the number of nests and chicks of the year. These indicators make it possible to monitor these nesting species and improve knowledge of these populations.

Once analyzed, the data will be stored in a public database (ORA).

Location of actions

Monitoring will be carried out in five colonies: Fréhel, Verdelet, Bréhat, Plouha and Cézembre.
