COMPARISON OF AQUATIC BRYOPHYTIC AND LICH EN FLORA OF 2 CREEK TYPES (FOREST CREEKS AND MEADOW CREEKS) IN THE SPESSART

The aquatic bryophye and lichen flora in 6 creeks (3 flowing through m eadows and 3 flowing through forests) in the northern part of the Spes sart (Sandstone) has been studied. The distribution of particular spec ies is shown in distribution maps. Distribution is compared with the t ype of creek (meadow or forest creek). A differentiation between moss- rich shaded creeks and sunny creeks could be shown. The nutrient conte nt of the water is extremely low. The pH ranges from 4.1 to 7.2. There were 34 bryophyte species and 8 lichen species found. Verrucaria rhei trophila and Hymenelia lacustris have not been reported for the Spessa rt before.
