It also protects beaches from erosion, provides shelter for fish and mollusks, and produces oxygen. Its presence is so valuable that it was declared a UNESCO World Heritage Site.<\/span><\/p>\n<div style=\"width: 410px\" class=\"wp-caption alignnone\"><img fetchpriority=\"high\" decoding=\"async\" src=\"https:\/\/www.saveposidoniaproject.org\/formentera\/wp-content\/uploads\/2017\/03\/Manu-San-Felix-1.jpg\" alt=\"Posidonia Formentera\" width=\"400\" height=\"179\" \/><p class=\"wp-caption-text\">Photography: Manu San F\u00e9lix<\/p><\/div>\n<h2><b>Where is the posidonia in Formentera?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">You&#039;ll see it (although you might not always know it) on many of the island&#039;s beaches. Especially in Ses Illetes, Es Pujols, Migjorn, and around the islet of Espalmador. It also appears as dried debris on the shore: those brown &quot;algae&quot; that sometimes cover the sand are dead posidonia, and they serve a purpose of protecting the beach.<\/span><\/p>\n<h2><b>Why is it important to protect it?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Because it&#039;s extremely sensitive. It takes centuries to develop, and if damaged, it doesn&#039;t regenerate easily. The main enemy today is the uncontrolled anchoring of boats. A poorly placed propeller or anchor can destroy meters of grassland in seconds.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For this reason, ecological anchoring zones have been established, and dropping anchors in certain areas is prohibited.<\/span><\/p>\n<div style=\"width: 411px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"\" src=\"https:\/\/www.saveposidoniaproject.org\/formentera\/wp-content\/uploads\/2017\/02\/Manu_San_Felix_book_0067.jpg\" alt=\"\" width=\"401\" height=\"267\" \/><p class=\"wp-caption-text\">Photography: Manu San F\u00e9lix<\/p><\/div>\n<h2><b>What can I do as a visitor?<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Do not step on or pick up posidonia<\/b><span style=\"font-weight: 400;\"> while snorkeling.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Respect the mooring buoys<\/b><span style=\"font-weight: 400;\"> if you are on a boat.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">If you see dry debris on the beach, <\/span><b>do not remove them<\/b><span style=\"font-weight: 400;\">They are there for a reason.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Get informed<\/b><span style=\"font-weight: 400;\"> about guided tours and interpretation centers.
