Gargano 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. Most of the upland area, about, is part of the Gargano National Park, founded in 1991. The Gargano peninsula is partly covered by the remains of an ancient forest, Foresta Umbra, the only remaining part in Italy of the ancient oak and beech forest that once covered much of Central Europe as well as the Apennine deciduous montane forestsecoregion. The Latin poet Horace spoke of the oaks of Garganus in Ode II, ix.
Tourism
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 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 endemicvertebratefaunaevolved 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 rodentgenus 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 Mesozoiclimestone. 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. 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 a second karstic cycle occurred, producing the neokarst which removed part of the paleokarst fill.
Fauna
The Gargano Island endemic mammals included:
Deinogalerix - 5 species of gymnures, among them the giant D. koenigswaldi with a skull of c.20 cm length.
Hoplitomeryx - some 5 species of "prongdeer" with five horns and sabre-like upper canine teeth. They ranged from tiny to the size of a red deer, and large and small ones apparently occurred at the same time rather than one evolving from the other.
Mikrotia - 3 or more species of murine rodent. The largest species, M. magna, had a skull 10 cm long.
Columba omnisanctorum - one of the oldest pigeon fossils known. It probably was more widespread and if so, the older name C. pisana would likely apply to it.
Garganoaetus freudenthali and Garganoaetus murivorus - two species of falconid, the former larger than a golden eagle, the latter well-sized; endemic. The smaller species, which likely is the stratigraphically oldest, is closely related to Aquila delphinensis from La Grive-Saint-Alban, France, according to Peter Ballmann in 1973. Its closest living relatives are the small eagles.
"Strix" perpasta - a true owl, perhaps the same as the widespread Bubo zeylonensis lamarmorae, a paleosubspecies of the brown fish-owl but this taxon was usually known from later times.
Tyto - 2 or 3 species of barn-owls. The largest, T. gigantea, was up to twice as massive as the living eagle-owlBubo bubo. T. robusta was also large; this species and the former were endemic but actually seem to have been chronosubspecies. The supposed remains of the smaller T. sanctialbani found at Gargano are now placed in the widespread Tyto balearica.
