description Background and aims: The Elqui river basin is located north of the Coquimbo Region, in the semiarid zone of Chile. This body of water is particularly important due to the economic activities it supports and its high environmental vulnerability. The objective of this study was to determine the diversity and composition of the macrophyte flora of the Elqui river basin.M&M: Twenty sampling stations with plots of 1 m2were distributed in the three sub-basins that make up the study area. Inside each plot, all plant species were recorded along with their respective abundances. In addition, in each station some environmental variables were measured, which were analyzed together with the biological data.Results: A total of 51 macrophyte species and one alga were identified, with dominance of native elements with emergent habit. Statistical analyses indicate moderate differences regarding the floristic composition of the three sub-basins compared, these are mainly concentrated in the Turbio river. The analysis of the environmental data indicates that the variables that most influence the composition of species in the study area are: altitude, total suspended solids, redox potential and water depth.Discussion: Studies on macrophytes at the hydrographic basin level are practically null in Chile. This type of information increases knowledge on biodiversity andallows a more efficient management of continental aquatic systems.

Introducción y objetivos: La cuenca del río Elqui está situada al norte de la Región de Coquimbo, en la zona semiárida de Chile. Este cuerpo de agua es particularmente importante por las actividades económicas que sustenta y por su alta vulnerabilidad ambiental. El objetivo del presente estudio fue determinar la diversidad y composición florística de macrófitas de la cuenca del río Elqui.M&M: Se establecieron 20 estaciones de muestreo con parcelas de 1 m2 distribuidas en las tres subcuencas que conforman el área de estudio. Al interior de cada una de ellas, se registraron todas las especies de plantas presentes junto a sus respectivas abundancias. Además, en cada estación se midieron algunas variables ambientales, las que fueron analizadas junto con los datos biológicos.Resultados: Se identificaron 51 especies de macrófitas y un alga, con dominancia de elementos nativos y de hábito emergente. Los análisis estadísticos señalan leves diferencias en cuanto a la composición florística que presentan las tres subcuencas comparadas, las cuales se concentran principalmente en el río Turbio.El análisis de los datos ambientales señala que las variables que más influyen en la composición de especies del área de estudio son: altitud, sólidos suspendidos totales, potencial redox y profundidad del agua.Discusión: Los estudios relativos a macrófitas a nivel de cuenca hidrográfica son prácticamente nulos en Chile. Este tipo de información incrementa el conocimiento de la biodiversidad y permite realizar un manejo más eficiente de los sistemas acuáticos continentales.
