During Alerod (AL) the sedimentation of deposits was linked with formation of water basins, when climate became warmer and thermokarst processes took place. Pinus and Betula forests occupied the territory. Alnus andPicea spread in damp habitats. Warm and damp climate caused the increase of water lev...

During Alerod (AL) the sedimentation of deposits was linked with formation of water basins, when climate became warmer and thermokarst processes took place. Pinus and Betula forests occupied the territory. Alnus andPicea spread in damp habitats. Warm and damp climate caused the increase of water level in palaeobasins and fast sedimentation of organic material - lake marl and gyttja. Junipers (Juniperus communis) appeared in sandy soil. During all Alerod period the hydrographic regime in water basins was quite stable. Such water conditions appeared because of improved water circulation when the ground got warmer. In the Younger Dryas (DR2), climate got colder and dryer. The number of herb pollen increased. Open landscape dominated the territory, trees became extinct. Typical plants for tundra -Artemisia and Chenopodiaceae - were noticeable. Climatic changes characteristic to Younger Dryas are confirmed by rapid dissemination of birch. Climatic changes caused the change of sedimentation type. The soil erosion and sand drift started. The fast filling up of the basins by sand interrupted the organogenic sedimentation.
