FLORA IN FORMOSA

The Provinces of El Chaco and Formosa are part of an ecological unit, called El Chaco Park, with homogeneous flora and fauna; its is limited to the East with the Paraná and Paraguay Rivers; with the forest of Tucumán and Orán to the West; with the Pilcomayo River to the North and the Salado River to the South.

The existence of the Bermejo and Pilcomayo Rivers and their extensive flooding areas determine certain unique characteristics. However, except for the Northwestern sector that is dry, the Province is humid enough as to contain lively vegetation.

The galleries of forests predominate on the banks of the large rivers in Formosa; in the East we find the wetlands and flooding areas with their aquatic vegetation linking our country's two large forests: the mountain forests on the Yungas of Salta, Jujuy and Tucumán to the West, and the missionary forests that extend to the East.

There are natural groupings of white and red fern leaf acacias in this Province, along with guaiacums, itínes, locust trees and white sages. Large clusters of pindó and caranda palm trees and willows flourish in the areas near rivers and wetlands.

There are species belonging to the galleries of forests that grow as far as the Pilcomayo River and mainly in the homonymous National Park, there are the evergreen alder of the rivers, the drunken sage of white flowers, the spear sage, the ibirá pitá, the ñangapiré, the agarrapalos, and the timbó or oreja de negro. Lianas and epiphytes such as the aerial carnation, numerous orchids and a variety of reed called picanilla, also grow in the forest areas.
