  ABSTRACT
  In the Gelsari and Lentini marshes (Sicily, Italy), which constitute a vast and historically well-known wetland on the central eastern coast of Sicily, the crossing of an overhead high-voltage power line surprisingly had been planned and approved. This choice was made despite the high landscape value that these marshes possess, the environmental protection constraints they enjoy, the interest they hold for the biodiversity conservation in Sicily, and their extraordinary ability to attract avifauna. At present, the work, which began in August 2021, has resulted in the placement of all supports. An estimate of the risk of mortality of avifauna that the presence of the power line will produce has been made, limiting the survey to species of high conservation interest, which are among those present in the marshes. It turned out that the risks of collision of avifauna and especially of species considered of high conservation interest, due largely to the characteristics of the power line and especially its route, are extremely high; the damage that is likely to occur does not, therefore, seem to have been properly assessed, neither at the design nor at the approval stages of the project. Given that the impact of the power line does not appear to be mitigable, neither with regard to the landscape nor with regard to avifauna, considering, in the latter case, especially the high mortality risks to which species of high conservation interest would be subjected, it is believed that the only solution to avoid such damage is to make a modification to the route of the power line in the section affecting the marshes.
