Microclimate of nurse stands

Popis výsledku v původním jazyce

Contribution in an international conference book of abstracts. Monitoring of climatic conditions under birch stand and simultaneously on adjacent clear-cut is carried out on localities Liběchov (300 m a.s.l.), Nemojov (450 m a.s.l.) and Pustina (470 m a.s.l.). Birch stands on these localities originated in natural regeneration on clear-cut in the years 2000 (Liběchov, Pustina) or 2007 (Nemojov). Air and soil temperatures, air and soil humidity, solar radiation and precipitation were recorded in 10 min intervals. The impact of nurse birch stands on the air temperature and the number and severity of temperature extremes is limited mostly to the ground layer. In the height of 200 cm, the differences between stand interior and clear-cut were already minimal. The temperature effects were highest in cloudless days. Greatest temperature differences between stand and clear-cut during spring frost periods were recorded after sunrise. Nurse stand reduced frost occurrence inside, but limited air heating after sunrise. Differences in extreme air temperature between clear-cut and nurse stands gradually decrease with stand age, advancing natural opening of the canopy decreases shelter effect of nurse stand (Fig. 1). Soil moisture under dense birch stands were significantly lower compared to clearcuts due to interception and water consumption.
