Evaluation of Climatic Efficiency of Short Rotation Coppice in Landscape
Weger, J., Šír, M.
In this article micro and macroclimatic efficiency of short rotation coppice (SRC) of fastgrowing trees and grassland is compared. Two localities in different altitudes were studied – Pruhonice at 332 m a. s. l. and Nová Olešná at 561 m a. s. l. Air temperature and humidity at 0,5 m above the ground, soil temperature at 0,25 m below ground and average soil moisture in rooting zone (0,1–0,5 m below ground) have been measured automatically in 10 minutes intervals in grassland and short rotation coppice on both localities. Precipitation has been measured on the grass fields. In both localities it was found that CRP plantation in contrast to the grass field: (1) creates a microclimate which lowers the midday temperatures of near ground air in extreme hot days, (2) lowers temporal variations in the time course of air temperature and humidity, (3) systematically decreases the soil temperature. The microclimatic efficiency of SRC plantation is greater in the lower elevation (Pruhonice) than in the higher elevation (Nová Olešná). Air temperatures above crown canopy of fast growing trees correspond with the temperatures above the grass cover. Therefore we expect that transpiration will be the same of both vegetation types.
