An elusive otter has been caught on camera at Steart in Somerset, where the largest new wetland nature reserve in the UK is being developed by the Environment Agency and the Wildfowl & Wetlands Trust (WWT).
WWT Project Manager Tim McGrath worked with local residents to set the camera trap that took the photo after seeing otter prints in the soft mud on the banks of the stream.
Local residents have also built an artificial otter holt [den] on the site, which is visible in the left of the photo.
Eurasian otters declined sharply due to pesticide use in the UK between the 1950s and 70s and the disappeared from most of England.
Since those chemicals were withdrawn from use, they have started to spread out across rivers and wetlands and increased in numbers.
Steart Marshes is designed to be more than a nature reserve.
Rising sea levels are already reducing the area of tidal habitat in the Severn Estuary and 3,700 hectares are expected to permanently disappear under water by the end of the century.
As well as supporting wildlife, this habitat helps protect homes against flooding and is a nursery for important fish stocks. Several hundred hectares of new Atlantic salt marsh will form when the old sea wall is breached.
As climate changes further in the future, it will continue to protect and serve people, as well as wildlife.
