Energy exchange above the floodplain forest and spruce monoculture ecosystems was measured in Moravia in 1988 and 1989. The results showed that the floodplain forest ecosystem with better access to groundwater than the spruce monoculture evaporated more rapidly. A higher flux of energy was recorded daily in latent heat (65% of net radiation) above the floodplain forest canopy, in contrast with the spruce plantation where it reached 17% only. The estimation of the floodplain forest actual evapotranspiration during the first half of June reached its maximum 0.17 g/m²/s, i.e. 0.6 mm/h. During the same period the actual evapotranspiration of spruce monoculture reached a maximum about 0.28 mm/h, nearly a half of that of the floodplain forest.
