Vegetation/Land use

Mixed land use. Corkoaks are used for cork extraction. Understorey is used for pasture or recreational hunting.

Context of investigation

The experimental plot was initiated by the University of Lisbon, Centre of Forest Ecology. Most of the monitoring is focused on vertical carbon exchanges. As a by-product, a lot of hydrological variables have been monitored. The University of Potsdam is now investigating the understorey evapotranspiration in this stand. The objective is to understand the different stability regimes affecting the vertical transport of latent heat in different forest densities.
