Transpiration was measured by sap flow techniques (heat field deformationmethod) on individual trees and scaled up to stand level. The radial patterns of sap flow density showed narrow peaks in the outer part of the xylem, sapwood accounted for 47–60%of the xylemradius and 72–84% of the xylem basal area. Adult trees tolerated well both short-term flooding during the growing season and drawdown of the water table to a depth of 60 cm below ground level. The maximum and mean daily transpiration rates were 3.0 and 1.8 mm per day, and were thus similar to published data for Scots pine. The seasonal total transpiration (25 April–20 October 2000, 180 days) amounted to 322 mm, or 62% of the potential evapotranspiration over this period.
