Intensive Test Site Hohes Holz
Forest site to study ecohydrology and trace gas fluxes
The research site Hohes Holz is a mixed beech forest at the northern border of the Bode catchment. The main research goal at this site is the understanding of the hydrological and carbon cycles of the ecosystem under the influence of environmental changes. Thus intensive monitoring of carbon and water fluxes between the ecosystem and the atmosphere will be performed.
Water fluxes include for example total evapotranspiration determined with eddy covariance, stand transpiration measured with sap flow sensors, soil moisture measured in high spatial resolution with a wireless network.
Carbon fluxes include the Net Exchange of CO2 between the ecosystem and the atmosphere by eddy covariance, continuous soil respiration measurements, and soil and biomass carbon storage. Driving parameters such as net radiation, photosynthetic active radiation, precipitation above and below the canopy, air and soil temperatures are determined as well as phenology, fluorescence and PRI, respectively.
Knowledge gained by the measurements will be used to test and improve a soil-vegetation atmosphere (SVAT) model and further help to understand ecosystem processes and answer questions related to effects of environmental and land use changes on trace gas exchange.
