Flora y Fauna
The diversity of flora and fauna of the province of Salta is strongly linked to its orography; more precisely to the climate, which is a direct consequence of it. So we can, in great reason, divide the province into three large territories in terms of flora and fauna: the Cordillerana Region, the Valleys Region and the Chaqueña Region.
In the high areas of the Eastern mountain range and in the Puna there is a very poor steppe, which leaves large spaces of the ground uncovered. The soil, - arid - eroded by strong winds, only allows the development of cacti, xerophilous and hard pastures. The steppe is formed by low, crawling, thorny shrubs, with very small or leafless leaves; they are shrubs adapted to drought such as tola, jarilla, cardones, añagua, yareta, goat horn, very sought after as edible. Bushes of hard and yellowish grasses also grow. The cardons are notable, whose trunks store water and reach 2 m high.
Animal life is reduced to those groups that can survive in the harsh conditions of the environment. It has a poor fauna, represented by some species of great value for their fur: llama, vicuña, alpaca and guanaco, practically extinct.
The condor dominates the Andean heights; other birds in the area are very scarce, raptors such as the eagle and the hawk being the most common.
In Iruya and Santa Victoria, rodents such as the chozchorito, the dwarf cuisines and chinchilla, of very fine skin, the pericote of the sands.
Region of the Valleys
This area offers a wide panorama: its permeable lands, annual rainfall and the numerous rivers and streams that cross it allow a wide variety of plant and animal species. The subtropical forest develops in the area, acquiring its greatest exuberance on the eastern slopes. High-rise trees grow in it - over 25m - The typical trees in the region are pacarás, walnuts, carob trees, pines, blackberries, felling, acacias, ceibos, willows, cebiles, paradises, molles, piquillines, poplars, etc. ., foreign plant species can be developed with only special care.
The poultry fauna is particularly wide: partridges of the mount, martinette, parasal mount, charatas, chuñas, teros, hummingbirds, chorlos, owls, sparrows, etc. Among mammals we can name foxes, weasels, vizcachas, wagon tattoos, ferrets, anteaters and as animals with fine skins to otters and chinchillas.
With clayey soil in the West and sandy in the East, of jungle configuration, lush with gigantic specimens of quinos, oaks, tipas, lapachos, red and white quebrachos, guayacanes, urundeles and holy sticks
Curious and slender palm trees grow in the bathes of the East, and, more to the Southeast, yuchanes, lapachos, cebiles, chañares and other species characteristic of the dry zone.
The fauna of this region is the most varied. Monkeys, pumas, turtles, caraguayes, suris (ñandúes), peacocks, herons, antas or tapirs, anteaters, mayoatos, lizards and vampire bats live there.
