Change in carbon balance of a dry calcareous grassland caused by spontaneous afforestation.

Abstract

Changes in land use represent one of the most important components of global environmental change. An experimental site has been established in the Slovenian Karst (Submediterranean climate region) with the aim to investigate the effects of land use change on ecosystem carbon cycling. Paired eddy flux measurement design was used in order to assess net ecosystem exchange (NEE) of two ecosystems: extensively used dry grassland and abandoned grassland invaded by woody plants. The use of two eddy towers allowed us to detect the influence of land use change on C fluxes. In this work we present one year of measurements with the emphasis on distinct responses of NEE of both ecosystems to short term effects such as rain pulses.
