Both, hydrarch and xerarch successions lead to

  • medium water conditions

  • xeric conditions

  • highly dry conditions

  • excessive wet condition


A.

medium water conditions

Hydrarch succession takes place in water areas and the successional series progress from hydric to the mesic conditions. As against the xerarch succession takes place in dry areas and series progress from xeric to mesic conditions. Hence, both hydrarch and xerarch succession lead to medium water conditions (mesic)-neither too dry (xeric) nor too wet (hydric).
