Difference between Hydrosere and Xerosere

Hydro sere

  • Succession takes place in wet habitats
  • Its first step is the submerged plant stage
  • Plants of the first stage are- Elodia, Hydrilla etc.
  • Succession is limited within six steps such as- Submerged stage, floating stage, reed swamp stage, woodland stage and climax forest stage.
  • A hydro sere is a plant succession which occurs in an area of fresh water such as in oxbow lakes and kettle lakes.

Xerosere

  • Succession begins with bare rocks, deserts; example: dry places.
  • Its first step is the blue green algae as well as thalloid licken plant stage
  • Plants of the first stage are: Rhizocarpon, Rhinodina etc.
  • This succession is ended by six stage, such as – thalluid, licken stage, leafy licken stage, moss stage, herb stage, shrub stage and climax forest Stage.
  • Xerarch succession of ecological communities originated in extremely dry situation such as sand deserts, sand dunes, salt deserts, rock deserts etc.
