A new set of stamps is being issued marking the diversity of birds, mammals, insects and fish.
The 10 stamps feature the beaver, Atlantic salmon, kingfisher, beautiful demoiselle, water vole, grey wagtail, common mayfly, otter, brown trout and dipper.
Royal Mail worked with Professor of Ecology at Cardiff University Steve Ormerod on the stamp issue.
“In these stamps we celebrate our unique natural environment with a strong focus on the rich variety of creatures that live in and alongside our rivers.”
“This is such a wonderful way to celebrate the UK’s rivers and to send a message – quite literally – of why they are important.”
