Karkonoski National Park - Poland

In 1998 a permanent plot (50 x 50 m) was established at the height of 780 m asl in 100 year old spruce stand, where bulk deposition, throughfall and soil solution are collected. The investigations of health status of trees and floral characteristic have been carried out since 2001. The analyses are carried out in a certified laboratory of the Institute for Ecology of Industrial Areas, Katowice (Certificate No AB 325). The basic meteo data are taken from the monitoring station located about 1 kn from the plot.
