The environmental zoning in swamp regions allowed the evaluation of the environmental deterioration of the ecosystems in the Ecological Station of Taim (ESEC/TAIM), in Rio Grande and Santa Vitória of Palmar (in the State of Rio Grande do Sul - Brazil). Two different types of ecosystems were considered: swamp regions (ECO1 = Límnico Ecosystem) and the Marine Plain (ECO2 = Ecosystem Marine Plain). The ECO TOTAL (ECO1 + ECO2) presented 64% of the class APP (Permanent Preservation Area), 27.6% of ACP (Permanent Conservation Area), 5.6% of AUO (Occupation and Use Area), and in a smaller percentage the class AR (Restoration Area) with 2.8%. The environmental deterioration of ESEC/TAIM (ECO TOTAL) was 13.65%. The factorial analysis technique permitted the derivation of the structure of the data, showing the correlations among each variable (exuberance classes) and its respective factor, however this did not allow the separation of the groups or quantify the influence of one or more variables on another of interest (variable answer). It is recommended that the environmental zoning be elaborated by the environmental public organs in the other ecological stations and in the units of conservation.
