Due to a number of port development projects on the Humber Estuary, managed realignment schemes were created at Welwick and Chowder Ness, to avoid adverse effects on the Humber Estuary Special Protection Area (SPA), Special Area of Conservation (SAC) and Ramsar site.
Inundation of Welwick and Chowder Ness occurred in 2006 creating 45ha and 11ha, respectively of intertidal habitat. ABPmer was involved in the initial design, detailed environmental impact assessment and management and monitoring programme for these sites.
This monitoring is a legal requirement to ensure the sites are meeting objectives as set out in the Environmental Management and Monitoring Plan (EMMP).
ABPmer is responsible for co-ordinating monitoring requirements, analysis and interpretation of results as well as presentation of the results to annual meetings of an Environmental Steering Committee comprising regulators, regulatory advisors and environmental non-governmental organisations (NGOs).
The Plan and its implementation have regularly been cited as an example of best practice. The two realignment sites continue to be annually monitored to understand development post inundation.
