The paper reports on annual pine increment dynamics during the period of last 30 years in the Vesetnieki Station of Permanent Ecological Research with a different drainage level: transitional bog, tree stand between the drainage ditches, tree stand adjacent to ditch. The increment of basal area of annual rings has been found to be considerably higher in the site adjacent to ditch with the most intensive drainage level. The increment of annual rings of individual trees proved to be non-synchronic, therefore trees can be suggested to have different response to have different response to the influence of the same meteorological factors (amount of precipitation, for example). The annual increment data for the last four years (1997-2000) have been compared to the results of biogenous substance circulation measurements during the given period.
