| Description
| - This study reports on 3.5 years (2008–2011) of actual evapotranspiration (ET) measurements of two short-rotation poplar coppice (SRC) plantations in comparison with two reference grass covers (clipped turf grass and permanent grassland) in a rain-fed area of the Czech–Moravian Highlands in the Czech Republic. The Bowen ratio/energy balance method (BREB) was used to measure the ET of all the four investigated covers. Although the ET of the SRCs sometimes exceeded that of grass vegetation or the reference evapotranspiration (ET0) on an hourly, daily or monthly time scale, it was always lower over an entire annual cycle. The wide range of the annual ET totals for the SRCs was determined mainly by the different rotation periods and ages of the stands, along with the leaf area index (LAI), the state of the canopy closure, and tree heights. The lowest annual ET (344 mm) was observed during the 1st year of the 2nd rotation (following the winter harvest) in 2010. During that year, the SRC regrowth started only after mid-June, and the maximum LAI of the canopy, which was approximately 2 m in height and was not completely closed, reached 3.7. In contrast, in the case of a mature stand approximately 12 m in height in 2009, i.e., the 8th year of the 1st rotation, the maximum canopy LAI reached 7.5, and the annual ET reached its highest observed value (549 mm). The leaf area duration of the SRCs was always lower than that of the grass covers, and this seemed to be the main reason for the significantly lower annual ET totals of the SRCs. These results are in the middle range of ET values from 21 recent studies on poplar and willow cultures. The results of this study indicate that conversion of arable land into poplar SRCs instead of grasslands does not result in significant differences in ET of the agricultural landscape.
