    FW-I-5: Damaged timber – extent of random use

    The illustration FW-I-5 ’Damaged timber – extent of random use’ contains a biaxial chart. The chart shows the proportion of random use compared to the logging total in per cent as a line, and the proportion of damage causes compared to the total of random use in per cent in terms of stacked columns. A differentiation is made between causes such as wind/storm, insects and other causes. The proportion of random use decreased steadily until the turn of the century, amounting to roughly 10 per cent in 1999.

    FW-I-2: Incremental growth in timber

    The XY scatter chart FW-I-2 ’Incremental growth in timber’ shows dots representing the annual incremental growth on the area of ground (growth in thickwood with bark) in square metres per hectare and year, differentiated by the following tree species: spruce, beech, oak and pine, for the periods of 2002 to 2008, 2008 to 2012 and 2012 to 2017 respectively. As yet, there are no data available for the years of 2017 to 2022. The incremental growth rates for beech, oak and pine trees have declined since 2002.

    FW-R-2: Conservation of forest-genetic resources

    The bar chart FW-R-2 ‘Conservation of forest-genetic resources’ indicates the terrain of stands dedicated to the purpose of genetic conservation on the natural site (in-situ) of the occurrence of species and of stands and seed plantations cultivated for the purpose of genetic conservation outside their natural occurrence (ex-situ) in the years of 2004, 2010, 2012, 2017 and 2022 respectively. In the period of 2004 to 2010, the total terrain of in-situ stands increased to roughly 32,000 hectares.

    VE-I-3: Heavy rain impacting on roads

    The illustration VE-I-3 ’Heavy rain impacting on roads’ shows stacked columns describing the percentage of the section length of federal trunk roads subjected to an exceedance of heavy rain at warning level 3 (tempest). Five categories are illustrated for the impacts, according to the number of hours concerned. 1 to 3 hours, more than 3 to 6 hours, more than 6 to 12 hours, more than 12 to 24 hours, and more than 24 hours. The highest category is represented in a few years only.

    WW-I-9: Spring algal bloom in lakes

    The line chart WW-I-9 ’Spring algal bloom in lakes’ shows the calendar week with the onset of spring algal bloom – for the years 2003 to 2021 and for the North German Plain, the uplands as well as the Alps-and-foothills. In each case the median is stated for 20 selected lakes. There are no data available for the years of 2012 to 2015. Depending on the region, spring algal bloom in 2003 still occurred in the calendar weeks 17 to 19, whereas in 2021, this process began as early as the calendar weeks 11 to 13.

    WW-I-6: Low water

    The bar chart WW-I-6 ‘Low water* shows – for the years of 1961 to 2021 – the number of low-water days in the water-balance related winter half-year (1st October of the previous year to 31st March) and in the water-balance related summer half-year (1st April to 30th September) respectively, prevailing in Germany’s river basins. The structure of the indicator is characterised by individual pronounced low-water events which occurred latterly in the period from 2018 to 2020.

    WW-I-3: Mean discharge

    The bar chart WW-I-3 ’Mean discharge’ shows the mean runoff depth for all river basins in Germany in the hydrological winter half-year (1st November of the previous year till 30th April) and in the hydrological summer half-year (1st May till 31st October) in the years of 1961 to 2021 in millimetres. The runoff depth in the hydrological summer half-year of 2021 decreased significantly during the period of observation, in the amount of slightly more than 100 millimetres.

    WW-R-2: GAK funds for flood protection

    The stacked columns chart WW-R-2 ‘GAK funds for flood protection’ shows the amount of public expenditure on investments made in flood protection measures in million Euros from Federal Government funding, Länder funding, and from additional national funding as well as EU funding during the time series 2007 to 2021. The expenditure has increased significantly since 2013 reaching its highest point in 2018 with just under 400 million Euros. It was possible to reach the same level in 2021.

    BAU-R-2: Green roofs in cities

    The illustration shows a biaxial diagram. For 2020 the green roof area in 15 cities with a population in excess of 500,000 inhabitants per square metre per inhabitant is illustrated by a bar chart. In addition, the percentage of green roof area in respect of the overall roof area examined is illustrated in dot form. In 2020 the green roof area amounted to 0.8 square metres per inhabitant and to approximately 10 per cent of the overall roof area examined.
