Corncrake Cover Advice

Corncrakes spend most of their lives in tall vegetation; or ‘cover’. Early cover is essential for corncrakes returning from their wintering grounds in April and May, while late cover is important at a time when most of the surrounding grassland has been cut or grazed.

Corncrake cover can be a difficult habitat to create and maintain.

This tool allows you to get targeted advice on any corncrake cover areas that are you having problems with. Following submission of the form with a photo, we will get in touch with you to give you tailored advice.

What is Corncrake Cover?

Corncrake Cover is areas of grassland that contains clumps of tall plants. Corncrakes require vegetation which is at least 20cm (8 inches) high for the entire breeding season.

It often comprises plants such as nettles, flag iris or cow parsley. The aim is to have this vegetation at least 20cm high by April.

In agri-environment schemes, Corncrake Cover needs to be adjacent to areas of late cut silage.
