L’O3HP (Oak Observatory at the OHP) interdisciplinary and experimental approaches to study Mediterranean forest functioning under climate change

The need to improve our understanding of the functioning of Mediterranean forests in the light of their future evolution, has led to the elaboration of a program concerning the Downy Oak forest. It's one of three major species of importance in the region of the French Mediterranean, and covers more then 250.000 ha in the Provence-Alpes-Cote-d'Azure (PACA) Region.

This program is complementary to pioneer programs at Puechabon for Holm Oak, installed and run by the CEFE in Montpellier, and at Roquefort la Bedoule for Aleppo Pine, installed and run by the INRA Avignon.

The O3HP program is managed and coordinated by a consortium of the IMBE/OSU-PYTHEAS/ECCOREV and is strongly supported by the Institute for Ecology and Environment (INEE) of the CNRS. The installation of the dedicated field site and laboratory has further received substantial financial support by the PACA Region and the Conseil Général des Alpes de Haute Provence.

The central installation consists of an experimental field site, situated at the research center of the Observatory of the Upper-Provence (OHP, UMS CNRS Pythéas) at Saint Michel l'Observatoire, close to Forqualquier in the Alpes of the Upper-Provence. The site is thus named O3HP (« Oak Observatory at the OHP »). The O3HP is part of the national research infrastructure AnaEE-France.
