WP 3: Risk management

Monday 18 November 2013

Risk management in forest through different forms of control: ecological, genetic and silvicultural.

FORRISK project partners seek to develop concrete methods of risk management on the field through different experiments in forests.

Three main types of actions have been identified and each task of this group is in one of these main actions.

Action 3.1 : Ecological control


Test and develop methods of ecological control against biotic and abiotic risks from the project regions

Implementation :

Establishment of hedges protecting the inside of stands

Broad-leaved hedges (source: INRA Bordeaux)
  • Attractive varieties for Gonipterus platensis on Eucalyptus
  • Broad-leaves making physical and chemical barriers for Maritime Pine destructive insects.

Tests on the effect of a patch of broad-leaves on biotic hazards

  • Creation of favorable habitats for pests and parasitoids of maritime pine destructive pests

Management of hedges and riparian

  • Limitation of various risks: insects and pathogens, wind, fire, avalanches…

Action 3.2 : Genetic control

Objectives :

Test (or value tests) of the varieties resistant to biotic or abiotic risks of the project regions

  • Eucalyptus less sensitive to Gonipterus platensis
  • Radiata Pine resitant to fusarium
    Pine seedlings resulting from micro-cuttings (Source TRAGSA)
  • Maritime Pine less sinsitive to storms

Develop recommendations for forest reproductive material of Maritime Pine based on the resistance to cold, of the anchorage, of the productivity and of the quality of the wood.

Action 3.3 : Silvicultural control

Objectives :

Test and develop silvicultural actions to limit the biotic and abiotic risks in the forests of the project regions

Implementation :

Heterobasidion annosum (Source: INRA Bordeaux)
  • Pruning and thinning techniques to reduce forest fire risks
  • Application of Biochar and ash to reduce the effects of drought
  • Treatment and extraction of Maritime Pine stem to control Fomes
  • Multiple risk integration in forest management at property level
  • Analysis of forest owners’ reactions when confronted with risks
  • Itineraries improving the Douglas’s resistance to drought
  • Prompt supply of high quality seedlings of Maritime Pine by micro-cuttings for recovery after forest fire beginning of autumn
