The objectives of this paper are to compile and present the 1996 monitoring data which are forwarded to the international database in Helsinki, Finland, in November 1997 and to inform participating organizations and volunteers on the scope and progress of the monitoring programme on a national and international level. Additional non-obligatory data are also reported. In 1996, the biological part of the integrated monitoring programme consisted of a regular inventory of birds, leafminers and butterflies in the monitoring area, as well as inventories of the aquatic macrofauna present in the moorland pool Kliplo and observations on the performance of pine trees. The chemical-physical part included meteorological variables like temperature, humidity, the amount of precipitation and irradiation, together with chemical analysis of air, precipitation, leaves, needles, mosses and pool water. Where possible, the series of data are described, interpreted and compared.
