The "Environmental Zoning of swamps in the Ecological Station of Taim (RS)" allowed to evaluate an environmental deterioration of the existent ecosystems in the Ecological Station of Taim (ESEC/TAIM); municipal districts of Rio Grande and Santa Vitória do Palmar (RS). Two types of different ecosystems were considered: swamps zone (ECO1 = Ecossistema Límnico) and Marine Plain (ECO2 = Ecossistema Planície Marítima). The total ecosystem (ECO1 + ECO2) presented 64% of the class APP (Permanent Preservation Area), 27,6% of ACP (Permanent Conservation Area), 5,6% of AUO (Use and Occupation Area); in smaller percentage it was observed the class AR (Restoration Area) with 2,8%. The deterioration environmental average for the ECO1 was 10.32%, smaller that ECO2 (23.94%). The environmental deterioration of ESEC/TAIM (ECOTOTAL) was 13,65%. Regarding the regression analysis for ECO1, it was obtained a precision of 95%, with 06 environmental parameters whereas ECO2 with 04 environmental parameters obtained the same precision. With the factorial analysis it was possible to know the structure of the data, showing the correlations between each variable (exuberance classes) and its respective factor. However, it was not possible to separate groups or quantify the influence of one or more variables over another (answer variable), as for example: how many parameters are necessary to elaborate an environmental zoning; this question was answered by the regression analysis. It is recommended that the environmental zoning be elaborated by the public organizations in other ecological stations and conservation units.
