Baltic moderately exposed circalittoral rock

English name Baltic moderately exposed circalittoral rock Open code browser    Diagram icon

EUNIS habitat type code   A4.5 Level   3
Edition   EUNIS Habitat Classification 2012 - a revision of the habitat classification descriptions.

Description ( English )

Rock habitats in the Baltic infralittoral zone which are moderately exposed to wave action, currents or ice scouring. The exposure status is that impacting on the area concerned at the relevant scale. Thus there may be enclaves of different exposure status caused by localised variation in relief (e.g. steeper rock in sheltered areas). Note that it has been proposed that ‘exposed’ has an effective fetch of 5 – 25 km: this requires verification across the Baltic.
