Body ContentNatural treasure The 45 miles of coastline around Jersey is arguably the Island's greatest natural treasure. Unlike many land based habitats, the areas between high and low water mark surrounding the Island have remained relatively unchanged since the sea reclaimed the land around the Channel Islands thousands of years ago. Spring tides The seashore in Jersey is subjected to dramatic change every 6 hours due to the Island's unique position within the Bay of St Malo. Over the spring tide periods, which occur approximately every 2 weeks throughout the year, the tide can rise and fall in excess of 40 feet twice a day. Seashore life Life forms vary dramatically throughout the various habitats found on the Island's shores, from 'the splash zone' which is wet only on the highest spring tides down to the lower shore which is exposed only on the lowest spring tides. Conditions can be extremely hostile in these areas and many creatures and plants are well adapted in their own ways to survive the rigour of life on the shore. A variety of species have been found on the Island's shores, including over: 100 species of fish 80 species of worm 100 species of crustacean 30 species of green seaweed 60 species of brown seaweed 140 species of red seaweed Seashore leaflet Seashore rules leaflet Sandy shores leaflet Strand line leaflet Rockpools leaflet On the rocks leaflet Coastal wildlife watching code
