Thus, this marshland is an area of great significance in biological productivity, the main special plants that have adapted to the high concentration of salinity in its environmental. Already in less brackish water areas, the vegetation is dominated by reed, reed beds creating spots where several species of birds can nest, one area in which they feel more protected and abundant food.
The Natural Reserve of the Tejo Estuary is symbolized by the Avocet (Recurvirostra avosetta), which at the time this was sorted, it was predicted that about 75% of the population of this species nidificaria this area.
