Madeira is a typical oceanic island with unique biodiversity under increasing pressure. Madeira island is located 600 km off the Atlantic coast of North Africa, has an area of 742 km2 and a maximum altitude of 1861 m (Pico Ruivo). Madeira island comprises approximately 126 catchments and 200 streams ranging from 1st to 6th order.
