Trend in heating degree days in the EU-27 (1980 - 2009). Eurostat calculates heating degree days as (18 °C - Tmean) if Tmean is lower than 15 °C (heating threshold) and zero if Tmean is greater than or equal 15 °C; Tmean is the mean daily outdoor temperature, calculated as Tmean = (Tmin + Tmax / 2)

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.
