4.1 General site character

Habitat class % Cover
N22100.00

Total Habitat Cover

100

Other Site Characteristics

Il s'agit de deux anciennes carrières souterraines, creusées dans le tuffeau. Ces carrières ont servi de champignonnières. L'une des caves (la Seigneurerie) est partiellement utilisée pour du stockage de vin. La principale menace est liée au dérangement pendant la période d'hibernation. Malgré des aménagements anti-intrusion, les gaz d'échappement liés à l'activité du viticulteur (tracteur) ont un effet très négatif sur la cave de la Seigneurerie, avec un report d'effectifs importants sur 5 sites annexes situés à proximité immédiate, qu'il serait bon d'intégrer au réseau pour la cohérence du réseau de gîte.

4.2 Quality and importance

Il s'agit d'un site souterrain très étendu, avec un réseau complexe de galeries. Le site est, selon les hivers, le second ou le troisième plus important du département en hiver, au 3 ou 4ème rang régional et considéré d'importance nationale selon la méthode de hiérarchisation nationale (Roué, 2004). Plusieurs entrées existent, ainsi que des cheminées d'aération probablement utilisées par les chauves-souris. Le site est plutôt stable géologiquement, même si certaines zones laissent paraître des fragilités. Le développement souterrain exact est mal connu, et non projeté en surface. De même, l'usage par les chauves-souris (circulation...) est inconnu. Ce site est prioritaire au niveau national dans le cadre du Plan d'Action Chiroptères.
