. The annual cycle of canopy structure in two mediterranean shrubs in a pioneer zone of the mobile dune system in the Donana National Park, Scrophularia frutescens and Halimium halimifolium , has been analyzed. Destructive methods were used as well as a new non‐destructive method, based on frequency analysis of organ distribution within the plant canopy. S. frutescens shows strong seasonal changes of photo‐synthetic biomass, but little annual increment in dry weight. In H. halimifolium , seasonal changes are not as strongly differentiated as in S. frutescens , but a higher annual increment is shown. The canopy structure of both species and its temporal changes are compared with existingplant strategy models.
