What is Scots Pine Defoliation in Kampinos Park about?

The document analyzes the relationship between tree height, diameter, and crown defoliation in Scots pine trees over 130 years old in Kampinos National Park in Poland. Observations were made of 250 trees in 5 pine populations in 2017 and 2019, recording crown defoliation percentage and stand damage levels. The results showed a significant increase in defoliation between 2017 and 2019, especially for the most damaged trees on fertile sites, coinciding with a period of drought in Poland.
