2. Ash is an important timber and landscape tree

3. It is believed thatthe pest was inadvertently introduced from China with wooden boxes

4. 3000 ash trees in 22 localities of European Russia were examined

11. The invasive range of the emerald ash borer in European Russia

12. 10 YEARS AFTER THE 1ST RECORD OF THE EMERALD ASH BORER IN MOSCOW • It is recorded in 9 regions of Russia • It occurs as far as 460 km south from Moscow • The range occupies at least 150 000 km2 • The westernmost locality is 180 km from the border of Russia

13. Indigenous European ashes (Fraxinus excelsior) damaged by the emerald ash borer

14. CONCLUSIONS • The invasive range in European Russia is expanding. • The pest destroys both introduced and indigenous ashesspecies. • Ashes in forests, protective forest belts and green plantations are in danger. • The emerald ash borer will appear in adjacentcountries within several years. • The economic and ecological impact could be tremendous.
