Impact on ecosystem services
Targeted Ecosystem services
The primary purpose of the Kilnsea Wetlands Habitat Creation Project was to provide habitat with vegetation characteristics and a landscape type to meet the “Favourable conditions status” targets set for the Humber Estuary SPA.
This is linked with ecosystem services ‘landscape maintenance’ and ‘biodiversity’, and also ‘flood water storage’ and ‘dissipation of tidal and river energy’. It also provides ‘opportunities for recreation and tourism’ through becoming a tourist and bird watching attraction.

Involved habitats
Intertidal mudflat, saltmarsh and grassland were created as a result of this measure.

The measure Beacon Lagoons in the polyhaline zone of the Humber estuary was about the creation of intertidal habitat by transforming a part of the adjacent land into marshland and intertidal steep habitat with a moderately high change in the habitat quality.
From the ES assessment it is concluded that this measure generates overall a slightly positive expected impact for many ES, mainly for:
- “biodiversity”
- Cultural services
- Some regulating services: Erosion and sedimentation regulation (by water bodies); Water quality regulation: reduction of excess loads coming from the catchment; Erosion and sedimentation regulation by biological mediation; Climate regulation: Carbon sequestration and burial; Regulation extreme events or disturbance: Wave reduction.
The expected impact for the development target “biodiversity” is slightly positive.
The expected impact for the different beneficiary groups is slightly positive for indirect and future use and for local and region use.
