Degree of synergistic effects and conflicts according to WFD aims

The compensation measure ‘Shallow water zone Kleinensieler Plate’ was not designed to meet the requirements of the Water Framework Directive (WFD). However, it covers five of six pressures the oligohaline zone of the river Weser 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	Additional subtidal areas (e.g. shallow water zone) were created.
S.I.	1.1	Habitat loss and degradation during the last 100 years: Intertidal					X	Additional intertidal areas were created (e.g. tidal mudflats).
S.I.	1.4/ 1.5	Gross change in morphology/hydrographic regime during the last about 100 years				X		The measure recreated habitats which got lost on a large scale due to river straightening and deepening measures in the past. Therefore, the measure contributes to mitigating the negative consequences of the gross changes in morphology and hydrographic regime which took place during the last 100 years.
D.I.	1.3	Land claim during the last about 100 years					X	Land was given back to the river; the tidal influence on the project area was increased.
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		By trend, the measure implementation leads to less maintenance effort in the river Weser due to additional sedimentation area on the Kleinensieler Plate.

S.I. = state indicator;
D.I. = driver indicator
