In year 2000 representatives of the atlas groups mapping the European vascular plants, mammals, birds, amphibians, reptiles, fungi and invertebrates agreed to use the CGRS as a common grid for species distribution mapping. The CGRS grid is modified from the Military Grid Reference System (MGRS). The MGRS itself is an alphanumeric version of a numerical UTM (Universal Transverse Mercator) or UPS (Universal Polar Stereographic) grid coordinate.

Some 97.5% of water on the Earth is salt water, leaving only 2.5% as fresh water. Of this over two thirds is frozen in glaciers and polar ice caps. The remaining unfrozen fresh water is found mainly as groundwater, with only a small fraction present in rivers, lakes or in the air. Water is a precious resource, use it responsibly and don’t waste it!
