what is xerach
Dear student,
Please find below the solution to the asked query
The succession initiated on bare rock or wind blown sand where water is low is termed as xerarch. The first plants to colonize here are crustose lichens like Rhizocarpon, Rhinodina and Lecidea. Foliose lichens (Dermatocarpon and Parmelia) replaces the crustose lichens which in turn are replaced by mosses like Polytrichum, Tortula etc. After mosses herbs occupy the land which is replaced by shrubs like Rhus and Phytocarpus. Finally the climax species i.e. forests becomes dominant in the land.
Hope this information will clear your doubts about the xerarch.
