National forest inventory

from Wikipedia, the free encyclopedia

The Federal Forest Inventory (BWI) is a large-scale forest inventory prescribed by the Federal Forest Act , which must be carried out throughout Germany. The national forest inventory records the large-scale forest conditions and forest production possibilities in Germany . Their results are an indispensable basis for forest, trade and environmental policy planning and decisions. So far, three national forest inventories have been carried out ( West German states ) and two inventories in the East German states .

  • First Federal Forest Inventory (BWI I, 1986): The Federal Forest Inventory was carried out for the first time in West Germany between 1986 and 1989.
  • Second National Forest Inventory (BWI II, 2002): After German reunification in 1990, however, a repetition was necessary, which took place between 2001 and 2003.
  • Third National Forest Inventory (2012): The field surveys for the third National Forest Inventory began in April 2011 and were completed nationwide by the end of 2012. The results were published on October 8, 2014.
  • Fourth National Forest Inventory (2021): The fourth National Forest Inventory was prescribed for the period between April 2021 and the end of 2022.

The federal forest inventory is a terrestrial random sample inventory with permanent sample points. For this purpose, a grid with a line spacing of 4 km (basic network) was laid over the territory of the Federal Republic of Germany and tracts for the samples were set up at the intersections of the lines. In some areas, double or quadruple sample density was used.

The national forest inventories are also a basis for the annual national greenhouse gas reports (National Inventory Reports NIR) to which the Federal Republic of Germany has committed itself through the Framework Convention on Climate Change , as a signatory to the Kyoto Protocol and through EU decision 280/2004 / EC. In order to obtain reliable figures on carbon storage in the forest between the national forest inventories, the carbon inventory is carried out halfway through the inventory period, most recently the carbon inventory 2017 (CI 2017) with the key date October 31, 2017.

The legal basis for implementation is Section 41a of the Federal Forest Act.
