Data is available on-line at the website of the Bundeswaldinventur for the 1st and 2nd survey (see link above).
Results tables can display area/no. of trunks for different species groups, further disaggregated by L�nder, Ownership type, Canopy class, and Tree age class.

Forest inventory
The National Forest Inventory is a nationwide terrestrial inventory carried out on a random basis with permanent sample points. The sample (cluster) distribution is based on a nationwide 4 km x 4 km quadrangle grid, determined by the Gau�-Kr�ger coordinates system. Each cluster covers a quadrangle with sides of 150 m. The cluster coordinates give the location of the south-west corner of the cluster (plot). Each plot in the forest is the centre of angle-count sampling and sample circles with defined radii. The road inventory is conducted along the cluster boundaries.
Data collected on: tree species composition, timber volume, growth and use (by angle count sampling)), as well as trees over 50 cm high and under 7cm breast-height diameter (tree species, tree size, browsing, damage etc.), deadwood, trees up to 4 m in height, trees of 20 cm to 50cm (tree species, browsing etc..), site characteristics (gradient, aspect, form) and forest edges (within sample circles). There is also a road inventory to gain information on access.
