GES description |
All known elements of marine food webs are present and occur with normal density and diversity as well as at levels which ensure a stable species density and maintain the full reproductive ability of the species.
|
The diversity (species composition and their relative density) of the individual trophic levels is not negatively affected by man-made pressures.
|
The balance between the trophic levels is not adversely affected by man-made pressures.
|
The size distribution of individuals across the trophic levels is not negatively affected by man-made pressures.
|
The productivity of individual trophic levels is not adversely affected by man-made pressures.

Justification for non-use of criterion |
|||||
Justification for delay in setting EU/regional requirements |
At present, it is not possible to assess whether the food network as a whole will be in good environmental condition by 2020. However, the balance of marine food is expected to improve as the environmental targets for pressure factors and condition under the other descriptors are achieved.
|
Overall, the species diversity for neither phytoplankton nor zooplankton can be stated as being in good environmental condition, as the data base is currently too flimsy to be able to assess this.
|
Despite assessments of individual sub-elements of the food network, it is currently not possible to assess whether the food network as a whole is in good environmental condition by 2020. Going forward, work therefore remains in the regional conventions with the development of relevant indicators and the setting of relevant thresholds. For this, it must be ensured that there is sufficiently good data.
|
There is still insufficient technical basis and agreement on the methods for setting threshold values for D4. Reference is sometimes made to the assessments for the individual species groups under descriptor 1.
