Mire ecology GLOBE expedition 2015 Team Cats

Objective To analyse interactions between vegetation and environmental factors in the Koitjärve raised bog.

The study transect of 6 positions

Working process Position 6 Position 2 Position 1 Position 2 Conquering the mountain

Bog hollow plants Turbasamblad Peat mosses Sphagnum spp Küüvits Marsh andromeda Andromeda polifolia Valge-nokkhein White beak-sedge Rhynchospora alba Pikalehine huulhein English sundew Drosera anglica Harilik jõhvikas Cranberry Oxycoccus palustris

The deeper groundwater the more characteristic bog hollow species (according to Paal 1997) Share of bog hollow species Groundwater depth [cm]

The less canopy the warmer peat Temperature at 40 cm depth [ °C] Canopy cover

The more sunlight availability the more bog hollow species Share of bog hollow species Canopy-free area

Conclusion Groundwater level and sunlight availability are the main causes of vegetation differences in the Koitjärve raised bog.
