Protected area Environment discovering - Natura Coghinas
At the mouth of the river Coghinas there is a protected area, one of the most suggestive in Sardinia, in a wetland of great importance for many species of birds and plants.
The presence of the dunes, overlooking the estuary, creates an environment rich in species of great value, good indicator of the state of conservation of the area.
This is the name of our educational excursion in this particular environment.
The walking path will allow direct observation of the vegetation in the area, linked to the dune ecosystems and river.
It will be possible in particular:
observe the strategies adopted by plants to overcome the unfavorable conditions of sandy environments: plants with well developed root systems to capture water, thickened leaves and other mechanisms to limit the loss of water.
Learn about plant associations of the exclusive northern Sardinian coast.
know the uses of plants related to the tradition, the island in the first place. Examples are St. John's wort, mullein, helichrysum, plants always been linked to ritual magic - therapeutic
Note on other species present in the area:
Armeria pungens: its association with other species adapted to sandy environments (ephedra, helichrysum, figwort) is exclusive of the sandy beaches of northern Sardinia.
Helichrysum italicum: species exclusive of Sardinia, Corsica and the Balearic Islands. All parts of the plant are strongly aromatic. On the island, its use is associated with ritual magic - therapeutic said “S’affumentu”.
Hypericum perforatum (St. John's Wort): considered magical plant from the island tradition, it was collected during the period of the summer solstice St. John's to make amulets and medicines
Cakile maritima: pioneer plant of coastal dunes. It is the typical plant of Cakileto, the plant association characteristic of the beaches, in the area where there is accumulation of Posidonia oceanica deposited from storms.
Eryngium maritimum (calcatreppola or sea holly): pioneer species of shifting sand dunes, contributes to their stabilization. Although it is common on the coasts of the whole Italy, increasing human activity of the beaches, is narrowing its range.
Phragmites australis (straw River): Its name derives from the term fragmiteto, which indicates an association with typical vegetation of the marsh area, where Phragmites is clearly dominant, because of its intricate development, which hampers the growth of other plants. The fragmiteto, thick and compact, of considerable importance to many species of animals, giving them shelter and food.
We wait you, sure to make you feel good emotions, expressing the hope that a better understanding of the environment can help us to preserve it.
