Site description
Medium intensively managed grassland at 1000 m asl. The adjacent farm and facilities are part of the ETH Research Station. Eddy covariance flux measurements were started in 2006.
Landuse
Moderately intensive management with two cuts per year and cattle grazing in autumn
Soil & Geology
Gleysol
The area is formed by the quartiary deposits of the Reuss glacier. It is dominated by moraines from the Würm ice age.
