Background and aims: The drainage system in the Alto Valle of Río Negro (Argentina), is integrated by a network of drains, and was designed to collect excess irrigation water from agricultural establishments. This artificial aquatic ecosystem allows the development of vegetal herbaceous species. The progress of urbanization towards agricultural lands increased the use of drains, due the discharge of industrial and urban effluents. The increase in non-agricultural effluents contaminate these environments producing changes in biota abundance and diversity. This work aims to propose the syntaxonomic categories of vegetation associated to the drainage system and determine the relevance of vegetation as a biological indicator in environmental impact studies.
M&M: Floristic censuses obtained in previous vegetation studies were used and complemented with new surveys carried out during the period 2018-2019. Census were carried out with the phytosociological school of Zürich Montpellier methodology.
Results: The syntaxa found are described, according to the final phytosociological table interpretation. Its floristic, structural, syntaxonomic aspects and its potential as contamination bioindicator are discussed. Conclusions: Twenty-eight syntaxonomical categories were established: three classes; Five orders, five alliances, two sub-alliances and thirteen associations for the Alto Valle drainage system, organized according to three growth habits: floating, submerged and emerging aquatic. 80% of the associations have eutrophication bioindicator potential in the Alto Valle de Rio Negro drainage system. |

Introducción y objetivos: En el Alto Valle de Río Negro (Argentina) el sistema de drenaje, integrado por una red de desagües, se diseñó para la captación del agua proveniente del excedente de riego de establecimientos agrícolas. Este ecosistema acuático artificial permite el desarrollo de especies vegetales de hábito herbáceo. El avance de la urbanización hacia los sectores agrícolas aumentó el uso de los desagües, a partir del vertido de efluentes industriales y urbanos. Esto establece el principal problema de contaminación en estos ambientes produciendo cambios en la diversidad y abundancia de la biota. Este trabajo tiene por objetivo establecer las categorías sintaxonómicas de la vegetación asociada al sistema de drenaje y determinar la pertinencia del uso de la vegetación como indicador biológico en los estudios de impacto ambiental. M&M: Se utilizaron censos florísticos obtenidos en estudios previos de vegetación y se complementaron con nuevos relevamientos realizados durante el periodo 2018-2019, con el uso de la metodología de la escuela fitosociológica de Zürich Montpellier. Resultados: Se describen las sintaxa encontradas, a partir de la interpretación de la tabla fitosociológica final. Se discuten sus aspectos florísticos, estructurales, sintaxonómicos y su potencial bioindicador de contaminación. Conclusiones: Se establecieron veintiocho categorías sintaxonómicos: tres clases; cinco ordenes, cinco alianzas, dos subalianzas y 13 asociaciones para el sistema de drenaje del Alto Valle, ordenada en función de tres hábitos de crecimiento: acuáticas flotantes, sumergidas y emergentes. El 80% de las asociaciones vegetales poseen potencial bioindicador de eutrofización en el sistema de drenaje del Alto Valle de Rio Negro.
