4.4 Impact of tree species on biodiversity and ecosystem functions in lowland forests of the Kiskunság sand region

In our research we compare in 10 localities the remnants of the original oak forests with the native poplar, foreign poplar, pine and locust tree plantations. We estimate the biodiversity of plants and some animal taxa. We examine with field experiments how the ecosystem functions as production, predation, decomposition and pollination are working in this stands.
