19th Needle/Leaf Interlaboratory Comparison Test - 2016/2017
45 laboratories in 22 countries participated in the 19th Needle/Leaf Interlaboratory Test, but only 44 laboratories submit results in time. As test materials three spruce and one pine sample were submitted. Special thank to all colleagues for collecting and preparing samples for this ringtest. Ringtest sample 2 is avaliable now as reference material also for heavy metals (As, Co, Cr, Hg, Mo, Ni, Tl, V).
Re-Qualification Process after the 23rd Needle and Leaf Interlaboratory Test 2020/2021
The qualification process starts with the ringtest participation. All participating ICP-Forests laboratories must analyze at least all the mandatory parameters. Finally, each laboratory can download the qualification report together with the ringtest report. The laboratory passed for parameters highlighted in green and failed for parameters highlighted in orange. For the orange highlighted parameters a re-qualification is needed.  >>>

Classification Values for European Foliage Data
These classification values were fixed at the 3rd and 4th Forest Foliar Expert Panel Meeting, in the 13th Forest Foliar Expert Panel Meeting the names of these classes were also fixed. These classification values should be used for the harmonize classification of element concentrations in foliage samples from European surveys.  >>>
Forest Monitoring - Methods for terrestrial investigations in Europe with an overview of North America and Asia
The book present scientific concepts and methods that form the basis of the transnational, long-term (environmental) forest monitoring in Europe and looks at other initiatives at the global level. Standardized methods that have been developed over two decades in international forest monitoring projects are presented.

Foliage and litterfall reference samples
BFW has prepared and offers reference samples (Spruce needles, Maple leaves, litterfall sample-beech leaves, Pine needles) with known element concentrations to support the QA/QC in Europaen laboratories which participate in forest environmental monitoring. These samples can be used for the validation of the analytical methods.
