The trends are calculated using a median of pairwise slopes algorithm. Black dots represent high confidence in the sign of the long-term trend in the box (if the
5th to 95th percentile slopes are of the same sign). Boxes which have a thick outline contain at least three stations. Area averaged annual time series of percentage changes and trend lines are shown below each map for one area in northern Europe (blue line, 5.6 to 16.9 °E and 56.2 to 66.2 °N) and one in south‑western Europe (red line, 350.6 to 1.9 °E and 36.2 to 43.7 °N).

A rotting log is a mini nature reserve in its own right!
By removing dead or dying trees from woodland, a section of the natural nutrient-cycle can be lost. A lack of dead wood reduces species diversity by about 20 %. Avoid removing dead wood from your property. You could be doing away with thousands of invertebrate species and fungi.
