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

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.

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.

April
2011

Local Otterhampton School made a film about coastal change with WWT staff and the Somerset Coastal Change Pathfinder.

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.

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.

May
2012

The main earthworks began, but were soon held up by the wettest summer on record.

Sept
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
2013

Excavations began on the new creek system and the tidal lagoons.

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.

July
2013

The brackish area called Otterhampton Marsh was completed.

Aug
2013

The freshwater area called Stockland Marshes was completed.

Feb
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.

June
2014

Two wildlife hides were put in place. They are made from recycled shipping containers.

Sept
2014

The old sea wall is breached, letting the tides onto Steart Marshes for the first time.

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.

May
2015

First pair of breeding avocet are recorded on site.

July
2019

Freshwater parts of the reserve awarded recognition as a Priority Site of National Importance for dragonflies.

May
2020

Black-winged stilts nest on the Stockland Marsh.

Dec
2020

Awarded Green Recovery Challenge Fund support.

Nov
2021

Community project creates a giant willow longhorn sculpture.

May
2022

Awarded National Nature reserve status and become part of the Somerset Wetlands Super NNR.

July
2022

Site launches as a dragonfly hotspot with support from the British Dragonfly Society.

March
2024

Awarded Species Survival Fund support.
