Floristic Biodiversity

In the wetland, which includes the free waters and the flooded vegetation of the banks and lines, habitats with stands of Caniço (Phragmites communis), together with Tabúa (Typha sp.) and Bunho (Scirpus lacustris) dominate. There are also communities (or mosaics of communities) of vascular plants with floating macrophytes, rooted or suspended between the bottom and the surface: the Pinheirinha (Myriophyllum sp.), the Water lilies (Nymphaea sp., Nuphar luteo ) or even the Hyacinth -water (Eichhornia crassipes).

In some marginal areas along the Pateira, there is the occurrence of several tree and shrub species such as:

Willows (Salix alba, Salix sp.), Poplars (Populus canescens, Populus nigra, Populus sp.), Alders (Alnus glutinosa), Black Alder (Frangula alnus), Ash (Fraxinus angustifolia), Hawthorn (Crataegus monogyna), Elderberry (Sambucus nigra), Borrazeiras (Salix atrocinerea ), occasionally Oaks (Quercus robur), Loureiros (Laurus nobilis ), Elmeiros (Ulmus sp.) …

Among the allochthonous species are Eucalyptus globulus (predominant in the forest cover of the areas adjacent to the lagoon), and other trees of the Acacia and Hakea genera, these with infesting behavior and which are widespread in the vicinity of the lagoon.
