I chirotteri del Salento: relazione 2000
In this short synthesis readers are offered some results obtained during the bat survey campaign carried out in the province of Lecce (Puglia, southern Italy) in 2008.
The data collected in the eastern side of the peninsula, as it is shown in the annexed map, were analyzed with different methods, considering the sighting of the animals as the only certain proof of their presence. This campaign was launched with the aim to survey not only the already reported species, but also the Tarida teniotis reported in Puglia by reliable authors, and the Myotis daubentoni, which has been also electronically surveyed in the locality of Spiaggia Bella in the municipality of Lecce, at the border of a wide swampy area called Rauccio. As far as the localities of Roca, Acaya, Otranto, Pisignano, Castro are concerned, there are more historic testimonies and some reproduction sites, that will give greater monitoring opportunities in the future.
As far as the anthropophilic species are concerned - according to our small but intense experience - they are equally distributed over the territory, and the lack of sightings depends on the lacking identification of the hunting sites rather than on the absence of the animals.
It was even more difficult to look for the bats in the territories with a high rate of natural features, because it required particular post techniques and specific methods to highlight the presence of flying specimens through the collection of the sound track in the ultrasound, after which a slow work of visual identification followed.
