Communication with foresters -
Training Plan for forest officers (National Forests Office)

As specified in the initial proposal and requested by the co-financer DRAAF and ONF agents and foresters, some in field training sessions were organized by GIEFS for the identification of ozone-induced injury and crown conditions. The target audience were composed of DSF (Forest Health Department) and French foresters. The project actions interested strongly the managers of forest environments for the protection and conservation forests by an adapted global management. These results will be able to serve to establish lists of sensitive tree species for the forest management adaptation.

Forest sites studied in the context of this training belong to the RENECOFOR network, whose mission is to (i) detect possible long-term changes in the operation of a variety of forest ecosystems and (ii) better understand the reasons of these changes. 17 RENECOFOR sites were visited and followed during these training sessions. In total, around 70 people participated to this training, including foresters, engineers, technicians and ONF managers of "RENECOFOR" sites. To be most effective, these sessions were organized with small groups (3 or 4). The main objectives were that:

  • Foresters understand how ozone concentration is measured and how to change the passive sampler each month. An explicative notice was distributed to foresters.
  • To date, foresters able to recognize ozone-induced injury at the managed plot. In the case they detect ozone symptoms on new species, they could directly inform GIEFS.

The training sessions were based on the ICP-Forests methodology (Manual for the assessment of ozone Specific symptoms). A leaflet, resuming the visible ozone injuries for conifers and broadleaves, was made in the context of the FO3REST project and disseminated during the training session (Training session Foresters by GIEFS).
