Temporal changing of Tonnarella lagoon (Mazara del Vallo, Trapani) and its current ornithological value. Aims of this work were to highlight the importance of a small and artificial recently formed wetland area, that presents different interesting ornithological peculiarities. The Tonnarella lagoon is a breeding site of Little Tern Sternula albifrons and Kentish Plover Charadrius alexandrinus, both classified as “endangered” species in 2011 by the Red List of breeding birds in Italy; the site is considered of “national importance“ for Kentish Plover and “recorded site“ for the Sandwich Tern Sterna sandvicensis, due to the consistency of its wintering populations. Besides, the ornithologicalimportance of this zone increases by the presence of migrating species included in the “Birds” 79/409/CEE Directive and in the Bern, Bonn and Washington international conventions; their status is considered at risk in the near future, according to the most recent estimates in Europe. The value of this area has been also highlighted by the method of evaluation H.A.T., both for breeding and wintering species. Nevertheless, Tonnarella lagoon is at risk of disappearing, because of the competent Authority choices to use it as storage for the dredging of sludge extracted from the harbour of Mazara del Vallo.
