Distribution of the eelgrass Zostera marina L. in the coastal waters of Estonia, NE Baltic Sea; 270-277

Tiia Möller, Georg Martin

All the available data on the distribution of Zostera marina meadows in the coastal waters of Estonia, NE Baltic Sea, were analysed in order to achieve a generic idea of the historical and present status of eelgrass.Altogether 44 localities with eelgrass present were recorded in 1995-2005 as compared to 36 sites recorded in 1959-1984. The percentage of findings in different water basins ranged from 1.3 to 5.1 in 1959-1984 compared to 0.6-3.6 in 1995-2005. This suggests that no significant decline or improvement of the eelgrass meadows has occurred in the Estonian coastal sea. Yet there are signs of a negative impact of eutrophication on eelgrass.
