Introduction
The riverside woods, which are in a good state of conservation, have an important environmental and scenic function with the presence of native species such as white willow(Salix alba), narrow-leafed ash (Fraxinus angustifolia), elm (Ulmus minor), silver poplar (Populus alba), black poplar (Populus nigra), alder (Alnus glutinosa), elder (Sambucus nigra), the common reed (Phragmites australis) and bulrush (Typha latifolia), among others.
These ecosystems have a rich variety of birdlife, amphibians, reptiles, fish and mammals like the otter. One of the main threats to this habitat is the proliferation of invasive exotic and non-native species, which can replace and, in some cases, profoundly affect the structure and operation of the ecosystem.
On this stretch here, the problem is associated with the presence of giant cane (Arundo donax), ashleaf maple (Acer negundo) and blackleaf locust or false acacia (Robinia pseudoacacia), as well as the possible presence of pond slider turtles (Trachemys scripta) and of American mink (Mustela vison), which have been subjected to actions to try to minimise their negative effects.
