The 2008 European Marine Strategy Framework Directive (2008/56/EC) includes a re-quirement for EU Member States to report on the environmental status of the seas under their jurisdiction and to work to achieve Good Environmental Status (GES). This is de-fined by eleven qualitative descriptors, and one of them deals with „Food Webs‟. The Task Group 4 „Food Webs‟ descriptor reads: All elements of the marine food webs, to the extent that they are known, occur at normal abundance and diversity and levels capa-ble of ensuring the long-term abundance of the species and the retention of their full re-productive capacity. This report defines the terms used in this descriptor (section 2), describes the scientific understanding (section 3) and the relevant spatial and temporal scales (section 4). A framework to describe attributes of GES for food webs is provided in section 5. Click here to read the full report.
