The main objectives of the contribution were to: (i) describe the monitoring network created in the mountainous regions in the Czech Republic; (ii) assess the input of water and pollutants from the wind driven low clouds and fogs onto the forest canopy; and (iii) introduce new ground-level cloud water sampler designs. The mentioned activities were performed at three experimental catchments situated in the headwater regions of the main massifs of the Bohemian border mountains. They differ especially in the level of anthropogenic impacts on vegetation cover. In order to collect cloud water samples, the active and passive sample-taking devices were constructed. Fog water collector of the new design were developed and installed at the selected localities. A fog water study carried out over the 16-years period proved high acidity of fog water and high values of enrichment factors. The ammonia, sulphates and nitrates are the dominant species both in fog water and in precipitation.
