| Zusammenfassung |
| Field measurements from February 2003 to January 2004 in a humid (but dry in summer) crest heath wood-land (degraded
laurel forest) in the National Park of Garajonay, Canary Islands (Spain), were combined to calculate water balance components. The water
balance domain is at the surface of the catchment and is controlled by atmospheric processes and vegetation. This study found that annual
water income (rainfall plus fog water) was 1440 mm year-1, half of which was occult (or fog) precipitation, while stand transpiration
estimated from measurements of sap flow amounted, annually, to 40% of potential evapotranspiration calculated from measurements of
meteorological variables. The positive role of crest laurel forests, which transpire less water than is incoming from rain and fog is
emphasised.
