Résumé :	Following intensive dehydration measures, which in some cases continued until the 1980s, the number of crane breeding pairs declined in many parts of the Baltic. Today, a positive trend is emerging. In Estonia and Latvia the crane is a breeding bird covering large areas and is represented by 1500 to over 2000 pairs per territory. The average population density is 10 pairs per territory/100km2 in Estonia, and 4.9 pairs per territory/100km2 in Latvia. In Lithuania, the crane is widely represented by 400 to 650 pairs per territory The largest population densities have been recorded in protected zones (such as national parks and environmentally protected areas), especially in boggy areas, along the edge of moors and lake shorelines.
