MULTIRISK evaluates the combined effects of multiple biotic and abiotic hazards on the productivity of maritime pine plantations over the entire forestry cycle using empirical growth models (developed by Celine Meredieu (INRA) with the help of Margot Regolini (formerly EFIATLANTIC)), and simulates forest management alternatives that might minimize the risk of economic losses.

The three tested hazards are defoliation by the pine processionary moth (Thaumetopoea pityocampa), which can result in growth losses, infections by the pine root rot (Heterobasidion annosum), which can kill trees, and storm damages.

Two models are implemented in the project: Pinuspinaster for long term productivity at the stand level and the French Forest Sector Model for economic consequences of productivity loss at the scale of the regional (Aquitaine) forestry sector.

Silvicultural alternatives to be tested through simulations have been built with the help of local stakeholders during workshops, such as that organised by EFIPLANT in June this year, including forest management and forest health advisors.

MULTIRISK is a two year project (2016-2018) funded by RMT AFORCE.
