History of the site

This is an old private maritime pine stand recently harvested, and where the stumps were not removed. The arboretum is installed on a humid/heath land covered with 80% fern . Hardpan (alios) was observed at 55cm depth. It is also located within an experimental forest which is under an agreement between the owner, INRA forest research and the agricultural school of Bordeaux(Bordeaux Sciences Agro) to promote actions for research and education.This site was chosen because it has little slope and easy access. The plot has been fenced off to avoid damages caused by wild animals
