History

Near the entrance there is the inscription 549. The inscription, of the same type found at the Grotta del Cunicolo and at the Androne dei Cocci, suggests that the cavity was at the time marked during the same exploratory survey of the area by the GGP. However, at present, the cave UM549 corresponds to UM549-Grotta di Pozzore III°, in a completely different regional locality. Although this cavity is at the minimum size limit to be catalogued, its inclusion is considered appropriate for the following reasons:

  • historical-archival memory of the cavities mapped and surveyed in previous decades;
  • presence of faunal species of community interest;
  • high karst potential of the wall in which it is located.

Notes on the name: At the entrance there is the number 549 in blue paint, not surveyed at the time together with the nearby UM550 & UM551.

Bio

Other hypogean fauna: A specimen of Callimorpha (Euplagia, Panaxia) quadripunctaria was recorded, a species of community interest listed in Annex II of Dir. 92/43/CEE.
