Bark beetles are monitored using a number of methods including damage surveys and pheromone trapping. As such methods are expensive and timeconsuming information is also regularly compiled from estimations of the number of infested trees removed from the forest. The reliability of those estimations is poorly documented. This pilot study investigated whether data from sales of attacked trees from public forests could be used for the assessment of Ips typographus infestations in Belgium. Results of the study indicated that local forest officers showed sufficient expertise in identifying and reporting attacks but sometimes overestimated attack levels. Despite some limitations such as the need to avoid working per flight season or with quantitative estimations of the number attacked trees sales records can be reliably used to identify stands infested by I. typographus.

La quantification de l abondance et de la distribution des ravageurs forestiers est un problème répandu dans le cadre de la gestion de la santé des forêts.
