Health condition of Scots pine stands in Murowana Goslina Experimental Forest Station in 1992-2006

Technical and biological monitoring was started in early 1990s in the territory of the Murowana Goslina Experimental Forest Station. The permanent monitoring included weather conditions, levels of sulphur compound emissions and dust depositions, as well as changes in tree health using the bioindication method. The long-term studies were carried out on 14 permanent study sites located in pine stands in age classes II-V This study presents the health condition of the tested stands in relation to the changes in the level of industrial emissions in the period 1992-2006.
