Experts from National forest centre (NLC) have indetified significant trees – sources of genetic material of the native tree and shrub species (black and white poplar, pear tree, white willow, narrow-leafed ash, bird cherry…). The most valuable of the trees will be nominated in National register and National list of Forest reproductive material. In the project LIFE Danube floodplains seeds or cuttings of those trees are picked for reproduction and preparation of the young trees. Young seedlings are later planted on the forest land in Danube floodplains during the realisation of the project. (Activity C.4)
