Ground vegetation is an important compartment of the ecosystem in terms of biodiversity and it takes an active part in the general functioning of the ecosystem. It is also a useful bio-indicator of the site conditions and its monitoring may enable the detection of environmental changes. Incident precipitation and throughfall Incident precipitation is sampled by 3 funnel-type bulk collectors in an open area, next to the LWF meteorological station. Sites where snow may be important are equipped with a bucket-type snow collector. Four snow collectors are used for plots where snowfall may be high.
Measurements are continuous.
Precipitation samples are collected from the field every second week. The measured parameters are given in Table 1. Litterfall samples are collected monthly from the field. The measured parameters are given in Table 2. Parameters measured in plant samples.
