Carbon and water fluxes in evergreen and semi-deciduous shrubs were studied in a Mediterranean cork oak woodland from early summer to autumn recovery. Rooting depth and leaf habits explained the contrasting strategies to exploiting light, water and carbon among species. Summer rain pulses mislead water use opportunistic shrubs. Average contribution of this shrub understory to ecosystem carbon assimilation was 17%.
