Plans unveiled for new wetland reserve in Horncastle

Flood-prone land south of Horncastle could be transformed into a haven for wildlife

Published 11th Oct 2025

A flood-prone site on the edge of Horncastle could be transformed into a new wetland nature reserve.

Lincolnshire Wildlife Trust and the East Mercia Rivers Trust are working together to create Harrison’s Holme, on land south of the A158 between the Rivers Bain and Waring. The area is often waterlogged in winter, making it unsuitable for crops or grazing.

Under the plans, the site would be re-landscaped to hold more water, with ponds, scrapes and native planting to boost biodiversity.

“Across Lincolnshire, we need to adapt to climate change," said Colleen Layton, East Mercia Rivers Trust.

"Making space for nature, creating more wetlands, reconnecting floodlands and just letting the rivers do what they want to do naturally, which is move.”

The scheme is partly funded by government through the UK Shared Prosperity Fund and Anglian Water’s Get River Positive programme.

If planning permission is granted, most of the major work is expected to be carried out this winter. An elevated viewpoint with seating and interpretation boards would allow visitors to see the reserve without disturbing sensitive species.

“The wetland will create a series of micro habitats that will support a diverse range of plants, insects, reptiles and amphibians," said Colleen.

"Small mammals and birds too. We're hoping that this will also increase ground nesting wading birds to the site.”

A public drop-in session will be held at Banovallum House in Horncastle on Thursday 16 October, from 3pm to 7pm, for people to view the plans and speak to the project team.
