Structure and litterfall in an Avicennia germinans mangrove stand in an arid zone on the Gulf of California, México were studied. The density (4700 ha1) and basal area (13.5m2 ha1) were more characteristic of a fringe-type mangrove stand, while average height (2.7 m), number of species in 0.1 ha (1), and complexity index (1.7) were closer to those of a dwarf-type mangrove. Structure is jointly influenced by a high rate of evaporation (2982mm per year), scarce rainfall (290mm per year, mainly in summer) and a brief period of tidal flooding (also only in the summer). Litterfall averaged 1.75 t ha1 per year, placing it even lower than the lowest value reported so far for mangrove litterfall (2–16 t ha1 per year). Litterfall showed a unimodal seasonal pattern, with higher values in summer. Rainfall, sea level and the ratio rainfall/evaporation explained 86% of the seasonal litterfall variability.
