Bioindicators, in general, living organisms are diverse in nature, plant or animal used to assess the quality of a given environment. Environmental degradation by soil salinity is a very old problem and expanse world generally more pronounced in arid and semi-arid regions. Plants that thrive in areas with high concentrations of salts are called halophytes, and some of them are used in recovering these soils. The aim of this work is to analyze three species of plants resistant to salt stress generate recommendations regarding the same, providing an indication of species that can restore the environment salinized. Randomly selected three species of plants resistant to salinity Copernicia prunifera, Atriplex nummularia L. and Gossypium hirsutum L, they were analyzed by a spreadsheet with characteristics that identify an ideal bioindicator species were then evaluated according to their physiology and etiology. Although the properties of A. nummularia has been highlighted by the recovery of soil salinized species Copernicia prunifera was considered as an ideal biomarker. Recommend to still further studies on this subject.
