TL;DR: In this article, the authors compared linear regression and Mann-Kendall trend analysis techniques often used to detect temporal trends in atmospheric deposition and found that the choice of method influenced the number of significant trends, and the slope of a trend needed to exceed a certain minimum in order to be detected despite the short-term variability of deposition.

TL;DR: In this article, a special transnational survey is performed in cooperation with the European Commission, based on a uniform 16 × 16 km grid of 4,800 plots with 103,000 trees in 27 countries.

TL;DR: The impact on individual trees of factors other than air pollution, e.g., biotic agents, was assessed in the 2013 Technical Report as mentioned in this paper, which focused on the impact of air pollution on tree crown condition and on sulphate and nitrogen deposition to forests.
