The illustration BD-I-3 ’Temperature index of butterfly species communities’ contains a line chart indicating the temperature index of butterfly species communities in degrees Celsius. In the illustrated period of 2006 to 2021 the line rises significantly. While the index for 2006 amounted to approximately 8.9 degrees Celsius, in 2021 the value amounted to approximately 9.1 degrees Celsius. However, the increase did not proceed continuously. In 2010 and 2011, the index value dropped, and also in 2017, the v

The illustration BD-I-2 ’Temperature index for bird species communities’ is a line chart with two lines. The first line shows the annual temperature index of frequently occurring breeding bird species for the period 1990 to 2021. The index value shows a significantly rising trend and has increased from 12.14 degrees Celsius in 1990 to 12.40 degrees Celsius in 2021. The second line illustrates the moving 5-year average. Here too the trend is rising significantly.

The illustration contains a stacked column chart which shows the beginning and duration of the phenological seasons for the periods of 1951 to 1980, 1981 to 2010 and 1992 to 2021. This demonstrates that, by comparison, winter has become shorter which also applies to spring and high summer. The early summer has become longer by approximately two days.

The biaxial chart FW-R-4 ’Utilisation of raw timber’ is divided into two thematic components. The upper part of the chart shows data on the utilisation of raw coniferous timber, whereas the lower part shows data on the utilisation of raw deciduous timber. The proportion of each type of subsequent utilisation compared to the total volume is indicated in stacked columns: material objects, energy production, exports, increase in storage.

The illustration contains a biaxial chart. The terrain of permanent grassland is illustrated by means of bars, in units of 1,000 hectares. In addition, a line illustrates the proportion of permanent grassland compared to terrain in agricultural use. Both time series contain data for the years of 1991 to 2021 indicating a trend reversal towards a rising trend.

A graph shows the agricultural nitrogen surpluses for individual years and as rolling 5-year means between 1990 and 2022. The 5-year-mean nitrogen surpluses in kilogrammes per hectare dropped from 117 to 77. The target for 2028-32 is 70 kilogrammes per hectare and year.

A graph shows the proportion of vulnerable ecosystems in Germany where the critical loads for eutrophication were exceeded between 2000 and 2019 and the target for 2030. In 2000, the share was 84 % and in 2019, it was 69 %.
