The contract connected to the KEOP call was signed by the winner of the procurement procedure and KASZÓ Forestry Co. The aim of the proposal is to eliminate invasive species, like Prunus serotina, Alianthus and Robinia in order to rehabilitate degraded Alluvial forests with Alnus glutinosa and Fraxinus excelsior habitats. The elimination of invasive species has been carried out at almost all parts of KASZÓ Forestry Co., especially in the most infected parts of the forest so that later on the LIFE project area would be overinfected by the semination of trees.
