Residents in Cornwall have been invited to plant grass at the dunes of a Cornish beach to try and stop changes to sand dunes.
The National Trust and the Making Space For Sand project said "dramatic changes" had been seen to the dunes at Crantock Beach in recent years.
It said the dune system was a "dynamic environment" which would continue to shift and change over time but it was changing too quickly.
Hannah Pickard, a National Trust ranger, said an increase in planting marram grass would help with spring tides and stormy weather.
She said: "The dunes are important for wildlife but also to provide a natural defence against increasing storms and rising sea levels.
"Planting more marram grass aims to improve biodiversity and also binds with the sand to reduce erosion of the dunes."
The trust said it was working with Plymouth University to understand how the beach and dunes could change in the long term and to help plan for the future.
The event will take place on Wednesday from 10:00 BST.
A spokesperson said anyone was welcome to join in and no experience was necessary.
