Impact of wind on litterfall in a coniferous forest of southern Sweden

Abstract (Swedish)
This thesis analyses relationships between the litterfall components needles, twigs, flowers, fruits, and total litterfall and climate variables (wind speed, air temperature, relative humidity, and precipitation) in a coniferous forest located in southern Sweden. Needles, twigs, and total litterfall were positively correlated with daily average as well as maximum wind speed, whereas negatively correlated with daily average temperature. Some months had higher than expected litterfall (03/2021, 01/2022, and 11/2022), and possible reasons include the storm Malik (01/2022) and two heavy snowfall occasions (03/2021 and 11/2022) that hit southern Sweden at those times. Due to the complicated interactions between environmental variables and their... (More)

Due to the complicated interactions between environmental variables and their interconnected impacts on litterfall, it is unrealistic to firmly state that wind speed is the dominant driver for litterfall. Other variables such as solar radiation, cloud cover, soil water availability, topography, and vegetation structure should be investigated in the future to achieve a broader understanding of the response of litterfall mass to different variables or to a particular event of external disturbances (storm, snow, drought).
