What is the role of bryophytes in preventing soil erosion?
Bryophytes prevent soil erosion. They usually grow densely and hence act as soil binders. Mosses grow in dense strands forming mat or carpet like structure. They prevent soil erosion by: (i) Bearing the impact of falling rain drops (ii) Holding much of the falling water and reducing the amount of run-off water.
