Degree of synergistic effects and conflicts according to WFD aims
The compensation measure ‘Tegeler Plate – Development of tidally influenced brackish water habitats’ was not designed to meet the requirements of the Water Framework Directive (WFD). However, it covers five of six main pressures the oligohaline zone of the Weser estuary is affected by (Table 2).Table 2: Measure effects on main pressures of the oligohaline zone of the Weser estuary
| Indi-cator | Code | Main pressures oligohaline zone Weser | Effect? | Description | ||||
| - | 0 | + | ||||||
| S.I. | - | Habitat loss and degradation during the last 100 years: Subtidal | X | As a result of measure implementation, additional subtidal areas were created. | ||||
| S.I. | 1.1 | Habitat loss and degradation during the last 100 years: Intertidal | X | As a result of measure implementation, additional intertidal areas were created. | ||||
| S.I. | 1.4/ 1.5 | Gross change in morphology/hydrographic regime during the last about 100 years | X | Natural erosion and sedimentation processes were promoted. | ||||
| D.I. | 1.3 | Land claim during the last about 100 years | X | Due to measure implementation, the tidal influence on the project area was increased and the Tegeler Plate – formerly used for agricultural purposes- was nearly completely left to natural succession. | ||||
| 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. | ||||
| D.I. | 2.4 | Maintenance dredging | X | Due to measure implementation, the Tegeler Plate provides additional sedimentation area. As a consequence, this may lead by trend to less maintenance effort in the river Weser. | ||||
