description The research work was carried out at Yuriria lagoon, in the state of Guanajuato, in order to know its vascular aquatic flora and vegetation, and to recognize the plant associations. Although the Yuriria lagoon is artificial (a dam), it presents a floristic richness which includes 47 species in 34 genera and 25 families of vascular plants. Gramineae, Cyperaceae, Compositae, Lemnaceae, Polygonaceae and Umbelliferae are the best represented families. The dominant life form is herbaceous and the attached emergent hydrophytes reach a total of 27 species. Only 2 arboreal elements (Taxodium mucronatum and Salix chilensis) were recorded. The principal aquatic vegetation of the lagoon, especially in shallow places at the south and southeast, is represented by extensive stands of cat tail (Typha domingensis) and bulrush (Scirpus californicus). The lagoon is in a clear aging process with the result of a continuous loss of aquatic habitats, which can be partially explained as due to spread of Eichhornia crassipes (waterhyacinth) which covers 60% of the surface. This situation is becoming more critical and in a short time the lagoon may disappear if the right measures to reestablish the equilibrium in the Lerma-Santiago basin, which is the main source of this aquatic environment, are not taken.

El presente trabajo fue realizado en la laguna de Yuriria, Guanajuato, con la finalidad de dar a conocer la flora y la vegetación acuática vascular de la laguna y las distintas asociaciones que en ella existen. No obstante ser una laguna artificial (embalse), este cuerpo de agua presenta una riqueza florística que comprende 47 especies y 34 géneros pertenecientes a 25 familias de plantas vasculares. Las familias mejor representadas son Gramineae, Cyperaceae, Compositae, Lemnaceae, Polygonaceae y Umbelliferae. Destacan como forma biológica dominante las herbáceas, entre éstas, las hidrófitas enraizadas emergentes alcanzaron un total de 27 especies. Solamente 2 elementos arbóreos (Taxodium mucronatum y Salix chilensis) fueron registrados. La vegetación acuática está dominada por extensos tulares de Typha domingensis y Scirpus californicus especialmente en lugares someros del sur y sureste de la laguna. El embalse está en un claro proceso de envejecimiento, ocasionando con esto una lenta pero continua pérdida de hábitats acuáticos. En gran parte esto es debido al desarrollo masivo de Eichhornia crassipes o “lirio acuático”, que llega a cubrir hasta 60 % de la superficie lacustre, situación que tiende a tornarse cada vez más crítica e inclusive en poco tiempo se espera la desaparición de la laguna, si no se toman las medidas para restablecer el equilibrio de la cuenca Lerma-Santiago, que es la que le da vida a este recurso acuático.
