THE SKIRT-MIRE: A NEW TYPE OF FLOATING MIRES

摘要

The authors studied the vegetation dynamics of Sphagnum dominated mires in the Beregi- sik plain(North-East Hungary). The Braun-Blanquet (1964) method was applied. During their work theydescribed a new type of floating mire. The authors suggest the name ,skirt-mire" after its shape andthey present it here. This widespread scraw formation process is observable on flooded willow mires,when willow trunks and branches grow long, bushy hair-like additional roots close to the water surface.In the water the abundant small floating dead plant debris felt with the hairy-like willow roots, witheach other and with the plants of the bottom. The succession was very fast on its surface.
