# Commission Regulation (EC) No 1737/2006 of 7 November 2006 laying down detailed rules for the implementation of Regulation (EC) No 2152/2003 of the European Parliament and of the Council concerning monitoring of forests and environmental interactions in the Community, Division (37): Tree numbers of the sample

Extent: E+W+S+N.I.

As in some samplings (foliage, increment) trees outside the normal plot (or sub-plot) have to be used, special numbers have to be applied. The numbers of these trees will start with a letter (F = foliage, R = ring analysis by increment borings, D = discs analysis) followed with a sequence number (e.g. F001). The numbers are to be reported.
