Mosses and liverworts

This group has not been extensively recorded during the last 40 years, which makes assessment of their current distribution difficult.

The district is home to an excellent collection of mosses and liverworts many of which are restricted to the upper valleys and cloughs of Calderdale. In a regional context they are scarce with their stronghold being within the South Pennines Natural Area. All the cloughs would repay further survey work.
