Loma formation

from Wikipedia, the free encyclopedia

As Loma lineup is a plant community called that in coastal deserts on the western slopes of the Andes exists. These deserts extend for a length of about 3500 km from the Peruvian- Ecuadorian border at about 5 ° 00 'south latitude to northern Chile at about 29 ° 55' south latitude. This hyperarid belt is only interrupted by the occasional river valleys. In Peru there are foothills, on the western slope, with increasing fog humidity at 450 to 600 m, this vegetation can develop.

Within this desert belt, with the Loma formations, very limited vegetation areas are formed , which are dependent on the fog that rises from the nearby Pacific Ocean . In addition, the vegetation is influenced by periodic but infrequent rainfall caused by the El Niño phenomenon . Many of the approximately 1200 plants found there species are highly endemic specialized and on these sites. A total of about 80 such formations are known.
