Loma-Formation

A Loma formation is a plant society that exists in desert deserts on the western slopes of the Andes. These deserts extend over 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 hyperaride belt is interrupted only by occasional river valleys. In Peru there are foothills, on the west slope, with increasing fog at 450 to 600 m this vegetation can develop.

Within this desert belt, the loma formations form highly limited vegetation areas that are dependent on the fog rising from the nearby Pacific Ocean. In addition, the vegetation is affected by periodic but rare rainfall caused by the El Niño phenomenon. Many of the approximately 1,200 species occurring there are strongly endemic and specialized in these sites. A total of about 80 such formations are known. Edit source text Weblinks Edit sourcetext
