dc.description.abstractUnderstorey vegetation of Scots pine (Pinus sylvetris L.) forests subjected to intense air pollution stress in the impact zone of one of the largest air pollution sources in central Lithuania – the nitrogen fertilizer plant Achema – were studied in 31 sample plots first in 1988 and again in 2004. A recovery of the vegetation was observed since the first sample time and interpreted as due to a distinct reduction of emission of nitrogen and sulphur oxides. Study stands were 85-100 years old with vegetation assigned to the Vaccinio-myrtillosa site type. Species which frequency changed little (Vaccinium myrtillus, Pteridium aquilinum) and increased in frequency (Trientalis europaea, Luzula pilosa, Vaccinium vitis-idaea, Melampyrum pratense) were typical of site type species. During the study period nitrophilous species with indicator values for nitrogen >= 6 decreased in frequency. In 1988 nitrophilous plants comprised 58% of all herbaceous cover, while in 2004 only 21%. According to the unweighted Ellenberg indicator values the stands had become darker and less acidic. A significant decrease in nitrogen indicators was observed in 2004. The process of ground vegetation recovery was documented in terms of an increase in keystone species (Vaccinium myrtillus, V.vitis-idaea) and a reduction of nitrophilous species (e.c. Rubus idaeus)en
