Fig. 3. The GEOCOD mapping system. The marked geocode is DE73 and is situated between the coordinates 46°36' - 46° 42' N and 24° 30' – 25° 40' E.Special cartographic supportsFor the representation of the chorology of the Romanian hornwort and liverwort species, a specialcartographic support has been realized by overlap several maps: the map of average multiannualprecipitations per year, the map of average precipitations per year, the hypsometrical map and the map ofmultiannual average temperatures for January. After the overlapping of these maps a new map wasobtained on which the following 17 climatic zones appear (Fig. 4):I – superior alpine zone: over 2200 m altitude, annual mean temperatures under -2°C and precipitations over1400 mm per year;II – inferior alpine zone: 2000-2200 m altitude, annual mean temperatures of -2-0°C and precipitations of1300 mm per year;18
