The environmental district of the High Murgia Park, "the last example of a large Mediterranean steppe present in Italy and one of the most important in the Mediterranean," includes the area of the north-west Murge located farthest inland and, in particular, the wide strip of territory parallel to the Adriatic Sea. It is on average 20 km away from the sea, is also 20 km wide and is located between the sub-coastal strip to the NE, the Bradanic strip to the SW, the Ofanto Valley and the Foggian Tableland to the NW and the sag of Gioia del Colle to the SE. Overall, the area occupies portions of territory belonging to 13 cities, including Spinazzola, Minervino, Corato and Andria.
An extraordinary naturalistic habitat, it is one of the least anthropic places in Italy, as far as crops are concerned as well, and has the largest extension of spontaneous vegetation: shrubs of berries, thistles, asphodels, mosses, lichens, aromatic plants, and wild orchids. From a geological point of view, this extensive plateau is marked by the presence of frequently visible calcareous soil, and, consequently, by imposing karstic phenomena. The most striking consequence of the karstic phenomena in the High Murgia is in the contradiction between a rich subterranean hydrography and an almost non-existent superficial hydrography. The main stratum (which reaches down as far as 400 m below sea level) and the superficial strata are, together, an enormous source of richness. The entire area is, in fact, protected as a "zone of possible draining-off (for drinkable and non-drinkable water) and of hydro-geological safeguarding."
