So far knowledge about distribution of the benthic habitats in the Baltic States has been rather limited and also in already designated Natura 2000 sites there is lack of detailed information about the seafloor, including characterisation and mapping of the benthic communities.
Senised teadmised Balti riikides esinevatest merepõhja elupaikadest on suhteliselt piiratud ja isegi juba määratletud Natura 2000 merealade kohta puuduvad detailsed andmed , sh põhjaelustiku kirjeldused ja kaardistus.
