The Chaco-Oranense region, or north-eastern plain of the province, has a forest-like configuration holding exuberant woods with gigantic cedars, quinua, oaks, Tipas and lapachos; svelte and curious palm trees grow at the eastern marshy areas; rich black and white locust trees, so called palo blanco, palo amarillo, palo santo, lapacho, cebil, chañar, guayacán, yuchán, tala, tusca, along with diverse cacti.
In some arid plains, leafless species and thorny bushes with scarce leafs, such as the locally known chaguar, the tusca, the quimil, the jarilla, the espinillo or the "sombra de toro" (bull's shadow), can be observed.
The fauna of the region is perhaps the most interesting, for it still contains wildlife species, such as the puma, the tapir or anta, the wildcat, the jaguar, the wild boar or mountain hog and the anteater.
THE PROVINCIAL NATURAL RESERVES
In addition to three National Parks (El Rey, Baritú and Los Cardones), the Salta province has numerous National Reserves in different places. They had been declared Provincial Reserves to preserve the nursery space of nature's genetic resources, to protect the environment surrounding catch basins that form the different rivers, to preserve the cultural, archaeological, geological, paleontological, and environmental patrimonies of Salta, and to guarantee the maintenance of the important biodiversity living on this territory.
