Dear participants of YPEF contest,

on 1^st of February we made slight changes in the YPEF Booklet III edition, that is published on YPEF website. The changes were limited to the page no. 110 and concerned statistical data on organization of forestry in Poland. Those of you who printed the booklet before this date please be aware that you need to replace this one page.

Good luck and have fun learning for the contest!
YPEF International Commission.
