] . They are distributed all over the world, but predominantly found in temperate regions.
Most (but not all) sedges are found in marshes, where they can be the dominant
vegetation . "C. muricata" is arare species which occurs in only a handful of locations withinEngland , and consequently is a protected species under the UKBiodiversity Action Plan . [cite web| url=http://www.ukbap.org.uk/UKPlans.aspx?ID=190| title=Action Plan for "Carex muricata"| author=UKBAP| accessdate=2007-05-06]Most carex species are very sensitive to artificial fertilisers, including lime. Their population will decline rapidly as the fertiliser is applied to their habitat.
