Percurso da Serra Amarela

NAME OF INTEREST - Waterside birch and laurel woods

CONCEPT - Natural Heritage

Alongside the watercourse there is a birch wood (habitat 91E0pt2) which falls within the alluvial forests of alder (Alnus glutinosa) and ash (Fraxinus excelsior), a priority conservation habitat. This birchwood is made up of a continual gallery of large birches (Betula celtiberica), their size being unusual since such trees usually suffer from repeated clearing activity. On the edge of the birch wood there is a small laurel grove (5230pt1), included in the arboreal undergrowths of Laurus nobilis, another priority conservation habitat. For this reason this locality is extremely important for nature conservation, having, as it does, two priority conservation habitats.
As well as the birch and laurel woods we can also see in these habitats the grey willow (Salix atrocinerea), ivy (Hedera helix), butcher’s broom (Ruscus aculeatus) and the royal fern (Osmunda regalis). Animals characteristic of this habitat are, amongst others, the otter (Lutra lutra), long-tailed tit (Aegithalos caudatus), and the dipper (Cinclus cinclus), Iberian emerald lizard (Lacerta schreiberi) and, in the river itself, the Iberian nase (Chondrostoma polylepis).
