Puéchabon

The site comprises three distincts experimental set-ups: (1) a long-term (>10 years) partial throughfall exclusion experiment replicated three times and crossed with a thinning (-30% basal area) experiment aimed at simulating long-term precipitation decrease in accordance with climate change scenario for the Mediterranean area (-30% of precipitation), (2) a total rainfall exclusion experiment using a mobile roof has been set up to simulate extreme drought events and modify precipitation seasonality, and (3) an eddy-covariance flux tower running continuously since 2001 to measure seasonal variations in ecosystem functioning and year-to-year flux responses to drought and climate.
