The TVAP area houses a diverse group of agricultural and forestry biotopes, and riparian areas that stimulate the existence of diverse animal species. The identified group of fauna species is of both regional and national interest, qualifying this region as an important territory in terms of conservation priorities.
Equally, the overwhelming richness in ora comprehends rare and protected species that are the result of its bio-geographical setting and the high presence of nature within the park territory, located on the border of two wide regions: the Eurosiberian and the Mediterranean.
The recorded rate of 480 vascular plants reveals a high and preserved floristic diversity and provides this area with a special relevance.
THE TVAP INTERPRETATION CENTER PROVIDES INFORMATION FOR THE REALIZATION OF THE ROUTE
This lagoon is the end result of an ancient open-pit mining exploitation site and currently stands as an extraordinary ecological niche where flora and fauna species interact in a particular manner. The high value of these species is paramount in the overall understanding of the Terva River Valley biodiversity.
The Lagoon of Brejo site includes wetlands, common alder and grey willow trees that are considered priority conservation habitats in Portugal. These refer to woodlands dominated by common alder wood (Alnus glutinosa), grey willows (Salix atrocinerea) and a significant quantity of birch trees (Betula alba). In a mosaic pattern with these woodlands are small areas dominated by sphagnum and an abundance of acidophilus reeds of J.acutiforus, J. conglomeratus and/or Juncus effusus.
In terms of fauna, the lagoon is recognized as the area with the highest number of identified species, which is revealing of its high species value. Some examples are the green sandpiper (Tringa achropus), the mallard (Anas platyrhynchos), the common moorhen (Galinula chloropus), the red squirrel (Sciunus vulgaris) and the salamander (Salamandra salamandra).
Riparian Galleries of Freitas and Meadows of Bobadela
The riparian galleries, normally associated with meadows, are dominated by common alder trees (Alnus glutinosa) in medium and low altitude areas and by birch trees (Betula alba) at higher altitudes. Well preserved on the valley, the galleries are continuous lands that include large-scale trees with, occasionally more than one row in each margin.
At the end of spring, the meadows present a rich palette of colors, of great beauty, fruit of its great floristic diversity, in which several species of wild orchids stand out, which generally arouse great interest (Dactylorhiza maculate, Orchis coriophora, Serapias lingua, Serapias cordigera).
These are the areas, together with their associated woodlands, registering the highest concentration of different groups of fauna species. In terms of birds, there is the white-throated dipper (Cinclus cinclus), in terms of mammals there are the otter (Lutra lutra), the fox (Vulpes vulpes) and the roe deer (Capreolus capreolus) and in terms of reptiles and amphibians, there are the Iberian painted frog (Discoglossus galganai) and the European pond turtle (Emys orbicularis).
Serra do Leiranco Mountain
At the top of this mountain, other than an overwhelming landscape with never-ending horizons, one can observe rare and protected floristic species, and some Iberian endemism with great conservation interest in Portugal, as for example the grassy Festuca elegans and the Echinospartum ibericum, the Eryngium duriaei subspecies Juresianum, the Festuca summilusitana and the wild clove (Dianthus langeanus).
In terms of fauna, the top of the Leiranco performs a mountainous biotope with several resident species, as the European rabbit (Oryctolagus cuniculus) and the rock bunting (Emberiza cia). Summer species include the northern wheatear (Oenanthe oenanthe) and the common rock thrush (Monticola saxatilis). The latter is listed as endangered species in the Portuguese Vertebrate Red List.
