Short History of the site

The site is part of the Forest Properties of Government of Navarra. Government of Navarra gave to Gestion Ambiental de Navarra S.A. the permission to install one of the arboreta in this site. Before site preparation the shrubs covered approximately 70% of the area. The main species were Prunus spinosa L., Crataegus monogyna Jacq. and Ulex europeaus L.. There were some isolated Pinus sylvestris L. also. This site was chosen mainly due to its location and Pyrenean influence which make it different from the other arboreta of the REINFFORCE project network.
