Isla de las Gaviotas is an island located in Río de la Plata estuary, Uruguay. The aim of this study is to determine and analyze plant species composition on this island and to identify vegetation zonation patterns. An angiosperm species list was generated using a qualitative sampling technique. We registered a total of 27 species, distributed among 18 families. According to species distribution patterns on the island, we propose four vegetation zones: North, Central, Southeast and West. Exotic species comprised 52% of the total number of species, reflecting a history of disturbance in the area. Nonetheless, this site also has a remarkable number of native species, in particular Heliotropium curassavicum, which is listed among Uruguayan species of conservation concern. Given that the loss of coastal plant species is a current problem, the proportion of native halophyte species recorded (37%) indicated the island’s importance as a relict of Uruguayan coastal vegetation.

Abstract In South American rivers, Eichhornia crassipes and other floating plants intertwine and form floating rafts commonly known as "camalotales" which are especially abundant during flooding periods. During extraordinary floods, hectares of floating mats are drifted by the Plata Basin Rivers. In the Río de la Plata several reports suggest that many animal and plant species from subtropical latitudes colonizes the area through these large rafts. These episodes are very important from the economic point of view because they cause several troubles to navigation and other activities. On the other hand, benefits to biodiversity are conspicuous, and many authors consider this process vital to the Río de la Plata wetlands and forests. However, there is scarce knowledge about Eichhornia rafts plant species composition. With the aim of creating an exhaustive list of the flora of the Eichhornia rafts, we visited the Río de la Plata coast during a massive Eichhornia rafts arrival. Thirty-two plant species were recorded in three different plant assemblages: Eichhornia rafts sensu stricto, floating reeds (canutillares) and embalsados. In front of this unexpected we emphasize the need to include this phenomenon in regional biodiversity conservation plans.
