The entire National Park belongs to the Mediterranean Region and has a typical Mediterranean climate, with pronounced summer drought that can last up to 9-12 months, depending on the year, particularly in the southeast low desertic
and thermic zones (West Almeria District).
The rodents' role in the intensification of desertic
conditions may be comprehended from the fact that a single species, viz., Indian desert jird, is able to excavate about 61,400 kg of stabilized soil per/km2 per day during summer and deposit it outside its burrow openings in a loose formation (Prakash, 1962).
This wind channel passes across the coastal-deltaic region and the Thar Desertic
areas of southeastern Sindh province.
The landscapes are divided into five--namely, the montane (kurinci), the pastoral (mullai), the desertic
(paalai), the riverine (marutam), and the littoral (neytal).
The natural environment presented itself in most of the cases as desertic
, arid, often quite compartmented, with large seasonal and daily temperature swings, frequently at extremely high levels.
In this area, three sites were chosen, firstly for their olive oil vocation, and secondly according to an aridity gradient ranging from mesomediterranean climate to desertic
climate (UNESCO, 1963; Fig.
