GERMAN FLORES, Daniel  y  MABEL SUVIRES, Graciela. Distribution and habitats diversity on the wetland of President Sarmiento Natural Reserve, San Juan, Argentina. Rev. Mex. Biodiv. [online]. 2012, vol.83, n.1, pp.194-200. ISSN 2007-8706.

In the Natural Area Protected President Sarmiento (APN), situated in an intermountain depression of an arid region of the Zonda valley, a multidisciplinary analysis was performed, to stablish a relationship between habitat diversity, relief, soils and vegetation. This wetland, Provincial Park Reserve President Sarmiento, is lies in a desertic area of central-western part of Argentina. Ten regional environment units within the basin, and 7 sites within the Park were identified and classified. The sites are located in the distal part of an extensive alluvial fan. The survey of the vegetation identified a total of 37 plant species grouped into 18 families. The Fabaceae and Asteraceae are dominants. The tamarindo (Tamarix gallica) was the exotic flora most adaptable to this environment, invading and moving on niches of native species that are particular to the identification ANP. The methology of work followed was very useful beginning from regional to local landforms analysis.

Palabras llave : Argentinean deserts; wetland of underwater discharge; Tamarix gallica.
