Gargano

Gargano (Italian pronunciation: [ɡar'ɡaːno]) is a historical and geographical sub-region in the province of Foggia, Apulia, southeast Italy, consisting of a wide isolated mountain massif made of highland and several peaks and forming the backbone of the Gargano Promontory projecting into the Adriatic Sea, the "spur" on the Italian "boot". The high point is Monte Calvo at 1,065 m (3,494 ft). Most of the upland area, about 1,200 km2 (460 sq mi), is part of the Gargano National Park, founded in 1991. In this region since 1978 a feud has been fought between the clans of the Società foggiana.[1]

The Gargano peninsula is partly covered by the remains of an ancient forest, Foresta Umbra, the only remaining part in Italy[citation needed] of the ancient oak and beech forest that once covered much of Central Europe as well as the Apennine deciduous montane forests ecoregion. The Latin poet Horace spoke of the oaks of Garganus in Ode II, ix.

The coast of Gargano houses numerous beaches and tourist facilities, including resorts such as Vieste, Peschici and Mattinata. The two major salt lakes of Lesina and Varano are located in the northern part of the peninsula. Gargano is the site of the oldest shrine in Western Europe dedicated to the archangel Michael, Monte Sant'Angelo sul Gargano.

Other tourist attractions include San Giovanni Rotondo, the Abbey of Santa Maria of Ripalta (Lesina) and the volcanic rocks, dating back to the Triassic Period, known as "Black Stones" in Lesina, as well as the Sanctuary of San Nazario.

Some 12 to 4 million years ago, during the Late Miocene to Early Pliocene, a highly endemic vertebrate fauna evolved on what was then Gargano Island due to higher sea levels than today. Several of these animals were subject to island gigantism.

The fossils are found in partially infilled paleokarst fissures across Monte Gargano. The Gargano Island fauna is known as Mikrotia fauna after an endemic rodent genus of the area. Initially named Microtia, this had to be corrected, because the genus name Microtia was already used for butterflies.

The surface features of the ancient karst developed in Mesozoic limestone. In these, sediment accumulated together with the remains of the local fauna, forming thick layers of reddish, massive or crudely stratified silty-sandy clays, known as terrae rossae ("red soils"). Through the mid-Pliocene, some of these deposits were flooded, probably due to tectonic movement of the Apulian Plate. Others were overlaid by other sediments of terrestrial or freshwater origin. In this way a buried, partially reworked paleokarst originated.

Later, as the ice ages cycle got underway, sea levels sank and the former island was continentalized. In the cool and semiarid conditions of the Early Pleistocene (some 1.8–0.8 mya) a second karstic cycle occurred, producing the neokarst which removed part of the paleokarst fill.

Bird species occurring at Gargano included (studied by Ballmann, 1973, 1976):
