The presented paper analyses how fog precipitation affects interception and throughfall in spruce mountain forests in the temperate zone of Europe. The plots selected for the collection of rainfall and throughfall were located within the area of nature reserve Babia hora, from which the data were collected from the year 2001 to 2005. The gauges were situated in four different locations (open space, crown's periphery, young stand and forest opening) at an elevation ranging from 1330 to 1350 m above sea level. The results indicate that in the examined region, the deposition of horizontal precipitation on vegetation surfaces occurs, which reduces the interception losses, and even causes the net gain of water. The positive effect of horizontal precipitation on water regime grows with the decreasing gross precipitation at open space, while this effect is evident for the precipitation in the form of rain, but not snow. The correlation coefficients between throughfall and rainfall fluctuated from 0.69 to 0.99 in the case of rainfall, and from 0.424 to 0.955 in the case of snowfall, which indicates strong correlation between throughfall and gross precipitation. High values of throughfall indices underneath crown's periphery suggest that under drip points we can expect the net gain of water, which has a positive effect on natural regeneration and understorey vegetation. The regeneration underneath crown's periphery is promoted not only by higher net precipitation, but also by higher amount of nutrients dissolved in precipitation. |
