Department of Botany and Plant Physiology Institute of Biology, Eszterházy Károly University Biodiversity and Conservation Research Group

Biodiversity and Conservation Biology Research group

The research group consists of researchers and teachers from universities and from the Institute of Biology and conservation professionals from Bükk National Park Directory and from other institutes. The Botanical Garden of Károly Eszterházy University is the research center of the gene resource conservation area, where more than 40 strictly protected species are involved in seed bank development and reintroduction programs. Two hardy orchids, Orchis purpurea and Cephalanthera damasonium represent growing individual number in the garden and further orchids will be introduced to do population ecology monitoring of orchid species occuring in the Bükk National park.

The main activities of the Research Group:

Ex situ conservation programme for protected plant species, seed bank development, different reproduction methods of bryohytes, vascular plants and in situ experiments.The population ecology of protected and rare animal and plant species in Northern Hungary. The life cycle of rare plant taxa during ex situ conservation programmes. Monitoring the effect of habitat treatments in the area of Bükk National Park.
