The Big Moss Map is a survey of Sphagnum moss in the Peak District and South Pennines.

We are looking for volunteers to walk sections of path and look out for patches of Sphagnum. We’d like you to tell us whether you saw any Sphagnum or not and if you did, some information about the patches you saw.

By doing this over many years, we will be able to detect whether we are seeing any changes in how much Sphagnum there is and the types of places it is growing in - information which will help us in our efforts to conserve blanket bog habitat.

Why survey Sphagnum mosses?
