La Concepción is a unique area for flora and birdlife.
In the coastal zone, where the influence of the sea is strongest, rushes and salt marshes predominate. Here, the species are adapted to wind and salinity, and there is a great abundance of endemic or rare species, both in the rocky areas (socarrell, sea cake, margalideta, thyme edge, etc.) and in the flooded and wet areas (salson revulledo or Triglochin barrelieri, among others). Additionally, in the submerged zone, communities of Alguero and Cymodocea nodosa appear.
The siliceous marine vegetation of the southern salt flats largely thrives on moist sandy substrates and supports the presence of Isoetes communities that include small rare annual species (Solenopsis Laurenti, Lotus parviflorus, or Radiola linoides), and endemics such as the tongues (Serapias nurrica).
The salt flats are a paradise for birds, precisely because of the presence of salt flats. It is an important wintering area for herons, flamingos, great cormorants, various species of ducks, such as the white duck, and numerous shorebirds. The shorebird group holds a special place during migration season, when they make up the majority of species that can be seen on the island. During the breeding season, the small black-legged passerine (plover) nests here.
