The terrestrial monitoring of forests in the Czech Republic is based on the harmonized methodology of International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (UNEP/ECE) and consists of three parts
: (a) national network of permanent monitoring plots (16 x 16 km), (b) regional intensive monitoring (network 1 x 1 km in selected areas), (c) set of permanent research plots established for the purposes of forest inventory and management planning. - (L'A.).
We have characterised principles of geobotanical indication methods, that may be used as a tool in forest monitoring. Further, we have discussed the vegetation role as an indicator of present conditions and transformations of numerous elements
of the natural environment, (especially climate and soils) occuring under the influence of anthropogenic influences and natural mechanisms. A few examples of possible applications of geobotanical indication methods for analysing changes of forest phytocoenoses
Degradation of forest ecosystems became widespread throughout the Northern hemisphere in the 1970's. Research projects were developed to clarify the role of air pollution and changes in climatic conditions by using new monitoring methods. Based
on old traditions and a newborn international cooperative program, a complex monitoring and research project was developed in Hungary to better understand the rapid changes in the forest ecosystems. - (L'A.).
The results of IIASA (Austria) based on forest monitoring programmes indicate that nearly 80% of coniferous and 40% of deciduous forests in Europe suffer from air and soil pollution effects. Satellite observations show that in Central Europe

Peculiarities of the impact of permanent chronic air contamination by dust and gaseous waste of the copper-nickel industry on morphological structure of Scots pine crown in secondary north taiga forests of the Kola Peninsula were investigated
In 1990-1991, five Scots pine forest stands of IV-VI age classes belonging to the Vaccinium, Myrtillus, and Cladonia forest-site type were observed along the atmospheric pollution deposition gradient in Estonia. In 1992, two new sites were added
