Temporal and spatial distribution of ozone symptoms across Europe from 2002 to 2014
One of the aims of ICP Forest is to estimate the potential risk of ozone on European forest
ecosystems. In this respect, ozone-induced, visible foliar injury is one of the most considered
response indicator to assess ozone impact on vegetation. In the present study, we analyze
visible injury data from the Light Exposed Sampling Sites (LESS) installed close to the Level
II monitoring plots, and where ozone concentration and meteorological parameters are also
measured.
Over the period of 2002-2014, nineteen European countries participated in the field
assessment of ozone visible injury according to the ICP Forests standardized methodology
(Schaub et al., 2010). Overall, 295 woody species were recorded, of which 28% are being
reported as symptomatic*. In 2009, the year with the highest number of countries
participating in the field campaign, 60% of the countries reported the presence of ozone
symptoms in some plants. In the same year, 12.4% (24 out of 194) of the woody species
were symptomatic.
Preliminary results for temporal trends reveal that four out of five countries with at least eight
years of data show a decreasing trend in frequency of symptomatic woody species,
statistically significant for two countries. Enhanced data quality control is being carried out to
perform further analyses to better quantify the spatial and temporal distribution of ozone
symptoms across European forests, also in relation to ozone exposure (cf. Schaub et al.,
2015)
Ozone risk assessment for European forests: a ten-year study on permanent monitoring plots
Ground level ozone still poses a serious threat to forest ecosystems across Europe and represents a priority for the UNECE Convention on Long-range Transboundary Air Pollution. The ICP Forests Expert Panel on Ambient Air Quality has coordinated the monitoring of ozone concentration and effects (i.e. foliar injury on native vegetation) since 2000 on an annual basis on intensive long-term forest monitoring sites across Europe (Level II). Methodologies, including quality assurance such as data harmonization, completeness and plausibility tests have been applied according to the ICP Forests Manual, parts X and XV (Schaub et al. 2010a & 2010b). Here, the authors evaluate the available data on ozone concentration, exposure, and foliar injury that have been collected at the very forest sites across Europe from approx. 80 – 150 plots and over 1’000 native species. Emphasis will be put on European scale analyses for i) spatial and temporal trends for ozone concentration; ii) different AOT40 assessment methodologies; iii) comparison between measured concentrations with passive samplers, respective AOT40 estimates and modeled EMEP outputs; and iv) foliar injury occurrence in relation to ozone concentration and ozone exposures respectively. Considering stress factors such as drought and physiological response indicators, these analyses will favor a comprehensive evaluation of ozone risk for European forests based on data from the very forest sites. Furthermore, these harmonized data sets will serve as a valuable basis for further integrated analyses and validation of models, such as from EMEP
2000-2013 ozone trends across Europe
Tropospheric ozone (O3) has been recognized as an important factor within global change, that has the capacity of reducing carbon sink strength of forest ecosystems and thus represents a priority for the UNECE Convention on Long-range Transboundary Air Pollution.
The ICP Forests Expert Panel on Ambient Air Quality has coordinated the monitoring of ozone concentration and effects (i.e. foliar injury on native vegetation) since 2000 on an annual basis on intensive long-term forest monitoring sites across Europe (Level II). Methodologies, including quality assurance such as data harmonization, completeness and plausibility tests have been applied according to the ICP Forests Manual, parts X and XV (Schaub et al. 2010a & 2010b). Here, the authors evaluate ozone concentration, exposure, and foliar injury data that have been collected at the very forest sites across Europe from approx. 200 plots and 20 countries. Emphasis will be put on European scale analyses for spatial and temporal trends for ozone concentration and AOT40 exposure. These harmonized and aggregated data sets will serve as a valuable basis for further integrated analyses and validation of models, such as from EME
