From a technical point of view, a major problem had to be resolved. Before the work was carried out, the bats accessed the factory cellar through a hole in the roof. As part of the roof restoration, a new access for the colony to its habitat had to be considered. The window in the lower part of the eastern façade of the building, which opens directly onto the cellar, was therefore unblocked to provide a new external access.
From a proactive point of view, the municipal team has taken into account the advice of Christian Lioto of the Finistère section of the Groupement mammologique de Bretagne (CMB) to install a nursery (or breeding site) under the roof of the 4e The work involved treating the existing openings to prevent predators from entering the building. The work envisaged concerned the treatment of existing openings to prevent the penetration of predators. The window of the 4e The east side of the factory was fitted with a suitable opening.
In the interest of preventionThe municipal team, in consultation with the companies working on the site, also ensured that the materials used to restore the roof and framework of the factory's attic did not contain no harmful treatment products. The installation of nesting boxes for swallows, as well as wooden cottages and plaster bricks to facilitate the establishment of other species of chiropterans, was envisaged in consultation with the Loctudy ornithology association.
