Abstract: The article shows how the plant transpiration cools the boundary level of the atmosphere. In a summer day, when the heat input is 5 to 6 kWh/m2 per day, in the mountainous and submontane areas of the Czech Republic (600 to 1400 m a.s.l.) the plant transpiration decreases: (1) maximum temperature of plant cover from 47 to 25 degrees C, (2) maximum temperature of boundary level of the atmos-phere from 29 to 21 degrees C, (3) maximum temperature of the soil in the depth of 15 cm from 15 to 8 degrees C. The cooling caused by plant transpiration substantially af-fects the energy balance of the land surface. Insufficient transpiration caused an increment of thermal energy of about 23
