AA.I3L11, AB.I3L11, AA.J3L11 and AB.J3L11 (NT)

Summary

Estimated observations of the biotope AA.I3L11, AB.I3L11, AA.J3L11 and AB.J3L11 were collected from the Baltic Sea area by expert judgements for HELCOM Red List of biotopes, habitats and biotope complexes.

Description

Baltic photic or aphotic coarse sediment dominated by multiple infaunal polychaete species including Ophelia spp Baltic photic or aphotic sand dominated by multiple infaunal polychaete species including Ophelia spp. and Travisia forbesii


The HELCOM Red List of Baltic Sea underwater biotopes, habitats and biotope complexes (2013) is an updated and improved version of the Red List assessment of marine and coastal biotopes and biotope complexes published in 1998. The classification of the report follows the proposed International Union for Conservation of Nature (IUCN) criteria and assessment principals but with some modifications for the Baltic Sea.


Altogether, the HELCOM Underwater Biotope and habitat classification (HELCOM HUB) includes 209 biotopes of which 59 were red-listed. Many of the red-listed biotopes are located in deep areas of the Baltic Sea due to oxygen-free nature as well as in the southwestern Baltic Sea due to the salinity restricted distribution of species in certain biotope. The HELCOM assessment relies heavily on expert judgment and inference, and the questionnaire data represents the estimated presence-absence data not in-situ measured data. This must be taken in account when observing the map presentation. The biotopes are shown on the map using the EEA 100 km grid.

This dataset displays estimated presence of AA.I3L11, AB.I3L11, AA.J3L11 andAB.J3L11according to HELCOM RED LIST assessment experts:

The biotope occurs mainly in the southern and western parts of the Baltic Sea area, but is very rare.

They are found in exposed abrasion areas (sandbanks, near-shore wave exposed shallow sublittoral).

Kiel bight to Darss sill. The distribution map indicates the area in the 100 x 100 km grid where biotope is

known to occur.

AA.I3L11, AB.I3L11, AA.J3L11 andAB.J3L11have been placed in the Red List classification to the category of Near Threatened (NT) biotopes.

Statement

ETRS-LAEA5210 is the recommended projection for reference grids by the European Environment Agency.

Based on proposal at the "1st European Workshop on Reference Grids", this grid is the recommened grid for EEA grids. This reference grid is based on ETRS89 Lambert Azimuthal Equal Area projection with parameters: latitude of origin 52° N, longitude of origin 10° E, false northing 3 210 000.0 m, false easting 4 321 000.0 m. Origin of grid is calculated from 0 m N 0 m E of projection. Parameters for grid calculation: start X-axis from origin: 0 m, start Y-Axis from origin: 700000 m, number of rows: 67 and number of columns: 84.
