The average annual production 477 g m-2 yr-1 was similar to those found in other Mediterranean evergreen forests with relatively high rainfall. The main components were the leaves 55 of the total biomass followed by acorns 22 and twigs 16 . Litter production was highest during May and June when the majority of the old leaves fell. When the meteorological conditions were favourable a second leaf fall collection was observed. Acorn production in 2001 was about nine times that of the previous years indicating a mast year. In general the different litterfall components were highly correlated in time except for the acorns. Interannual covariation was significant for leaves twigs and leaves catkins. Catkins were the most variable component with also strong seasonality acorns were also very variable with low seasonality while leaves were less variable and with the strongest seasonality. After accounting for seasonal covariation there were significant effects of rainfall on twig litterfall and of temperature on leaf litterfall the years with highest leaf litterfall being the hottest. litterfall Iberian Peninsula coark oak Mediterranean climate weather Résumé - Production de litière dans une forêt de Quercus suber du Montseny NE de l Espagne et relations avec les conditions météorolo-giques.
