The moss which only gathers on one stone: Tiny plant in Derbyshire Dale is one of world's rarest

Ramblers and climbers pass by without a second glance as they focus on the stunning scenery.

But only yards from their feet, in a raging stream, one of the rarest plants on the planet is growing.

A single square yard of stony riverbed in the Peak District contains the world’s entire stock of Derbyshire feather moss.

Derbyshire feather-moss is a species of aquatic moss which is only known from one site in the entire world. It is thought to have evolved in this one place in the Peak District and is therefore naturally rare.

Little is known about the environmental requirements of the moss, but the site and the area surrounding it are protected by Natural England, and the water quality is regularly monitored by the Environment Agency
