Stream water chemistry changes in response to deforestation of variable origin (case study from the Carpathians, southern Poland)

摘要

The purpose of the study was to examine the effects of deforestation of variable origin on the stream water chemistry, with a special focus on the NO3- ion. The research was conducted in 8 small catchments in the Tatra Mountains and 7 small catchments in the Beskid ' Slaski Mountains (the Carpathians, Poland). Relevant deforestation events occurred in the Beskid ' Slaski Mountains in the 1980s and 1990s, and were caused by intense acidic atmospheric deposition in the 1970s and 1980s, while tree stands in the Tatra Mountains were damaged abruptly by hurricane-force winds in 2013 and gradually by the bark beetle since the late 1990s.
