About Steart Marshes
A powerful natural tool in protecting against the effects of climate change
Rising sea levels are putting the squeeze on our coast
WWT and the Environment Agency have created Steart Marshes – one of the UK’s largest new wetland reserves - to protect local people from the effects of climate change, and create vital habitat for a variety of wildlife.
How it works
Steart Marshes proves you can protect homes and businesses from flooding using wetland technology that works with nature.
Project milestones
October 2024
March 2024
May 2022
Awarded National Nature reserve status and became part of the Somerset Wetlands Super NNR.
November 2021
Community project creates a giant willow longhorn sculpture.
December 2020
May 2020
Black-winged stilts nest on the Stockland Marsh.
July 2019
Freshwater parts of the reserve awarded recognition as a Priority Site of National Importance for dragonflies.
May 2015
First pair of breeding avocet are recorded on site.
April 2015
The first shoots of salt-tolerant plants are found, indicating that the marshes are starting to develop. Other ongoing wildlife monitoring undertaken by our volunteers includes great crested newts, otter , butterflies, wintering and breeding birds. Celebrated the official opening of the reserve, with the EA, volunteers, local community and organisations involved in the creation of the scheme. Start of partnership with Bridgwater College, first student placements.
September 2014
The old sea wall is breached, letting the tides onto Steart Marshes for the first time.
June 2014
Two wildlife hides were put in place. They are made from recycled shipping containers.
February 2014
The reserve was opened to the public. The villagers of Steart, Combwich and Stockland Bristol helped plant two new community orchards. It’s the first of many workdays at which local volunteers help develop and manage the marshes.
August 2013
The freshwater area called Stockland Marshes was completed.
July 2013
The brackish area called Otterhampton Marsh was completed.
June 2013
New flood defence embankments were created from the earth and clay dug from the creek system and lagoons. All the spoil was used on site so nothing had to be taken away or brought in, which reduces the carbon footprint of the project.
May 2013
Excavations began on the new creek system and the tidal lagoons.
September 2012
The last of over 3,000 great crested newts were collected from the new large intertidal area and moved to a number of ponds in Steart village. Badgers were moved to new setts that had been specifically made for them.
May 2012
The main earthworks began, but were soon held up by the wettest summer on record.
March 2012
An archaeological dig mapped and recorded remains found during the construction. They indicate that there has been a settlement on the Steart peninsula since late Iron Age.
March 2012
Sedgemoor District Council granted planning permission. There wasn’t a single objection from the community. The land where the new wetlands were to be created was immediately bought.
April 2011
Local Otterhampton School made a film about coastal change with WWT staff and the Somerset Coastal Change Pathfinder.
March 2011
The first diggers arrived. They built a freshwater wetland first, so it had time to mature before the main construction work started. This is where amphibians and mammals displaced by construction could take refuge.
2009-2011
A series of community meetings were held at which the EA, WWT and the contract engineers were involved. Proposals for Steart Marshes were presented to the local community which then helped shape the final design. A trial bank was also built in 2010, so the engineers had time to test how much the soil compacted and shrank before the main construction took place.
