Each site was out-fitted with bottle-funnel gauges and standard mechanical gauges placed on the forest floor andscreened bottle-funnel gauges to trap fog in open areas.As much as 42.5 em of fog water were collected beneath the forest crown during thesummer fog season although differences in crown exposure and dimension caused highvariability in seasonal totals caught beneath individual trees. A typical fog precipitation eventbegins during late evening and ends just after sunrise. It sometimes continues for several daysand produces fog drip amounts of up to 8 em.The nutrients and water captured from drifting fog by intercepting trees, shrubs, andgrasses affect water balances and nutrient cycling within such coastal ecosystems. Fog mayinfluence species composition, and the character of the soils and vegetation of such coastalforests must certainly reflect to some degree the prevalence of summer fog. aPseudotsuga menziesii aÁrvore Conífera aFloresta aNeblina aNutriente aForest1 aMORGAN, D.
