Degree of synergistic effects and conflicts according to WFD aims
The compensation measure ‘Shallow water zone Rönnebecker Sand’ was not designed to meet the requirements of the Water Framework Directive. However, it covers five of six main pressures the limnic zone of the Weser estuary is affected by (Table 2).Table 2: Measure effects on main pressures of the limnic zone of the Weser estuary
| Indi-cator | Code | Main pressures freshwater zone Weser | Effect? | Description | ||||
| - | 0 | + | ||||||
| S.I. | - | Habitat loss and degradation during the last 100 years: Subtidal | X | Additional subtidal area was created (shallow water zone). | ||||
| S.I. | 1.1 | Habitat loss and degradation during the last 100 years: Intertidal | X | Intertidal habitats (e.g. reeds) were created. | ||||
| S.I. | 1.4/ 1.5 | Gross change in morphology/hydrographic regime during the last about 100 years | X | Due to Weser deepening, many side habitats of the river including shallow water areas got lost. The compensation measure creates new side habitats and therefore contributes to mitigating the negative effects of the gross changes in morphology/hydrographic regime which took place during the last 100 years. | ||||
| D.I. | 1.3 | Land claim during the last about 100 years | X | The project area – a former disposal area without tidal influence – was reconnected to the river. | ||||
| D.I. | 1.7 | Relative Sea Level Rise | X | Project area provides additional holding capacity. | ||||
| D.I. | 2.6 | Capital dredging | X | There are no direct effects to be stated, but measure generally contributes to mitigating the negative effects of capital dredging. | ||||
