HTAP Activities: ICP Vegetation Parties at 29 th ICP Vegetation TFM, Dubna, Russia, 29 Feb - 3 rd Mar, 2016 Rest of Europe SEE EECCA Rest of world Czech Republic Albania Azerbaijan Egypt France Bulgaria Georgia Guatamala Germany Greece Kazakhstan India Hungary Macedonia Russian Federation Japan Italy Romania Mongolia Norway Serbia Pakistan Poland Slovenia USA Slovakia Turkey Spain Switzerland UK  Co-organisers of the 1 st Asian Air Pollution Workshop, Tokyo, October, 2015  Additional contributions from China, Republic of Korea, Thailand and Vietnam

ICP Vegetation: Risk of ozone damage to ecosystems Forest Grassland POD = Phytotoxic Ozone Dose  Risk of ozone damage to ecosystems low in arctic region  Risk highest in central Europe and parts of southern Europe, where ozone concentrations are higher and/or climate conditions conducive to high ozone uptake by vegetation

ICP Vegetation: Global assessment of evidence of O 3 damage to vegetation Collating data on field evidence of visible leaf injury and beneficial effects of filtering ozone out of the air

TOAR: Global Tropospheric Ozone Report  ICP Vegetation contributes to Tropospheric Ozone Assessment Report (TOAR): Global metrics for climate change, human health and crop/ecosystem research ’ www.igacproject.org/TOAR  ICP Vegetation contribution : Gina Mills is lead author for chapter on ozone metrics for vegetation; several participants contribute to this and other chapters
