Fungal and nematode threats to Australian forests and amenity trees from importation of wood and wood products
Canadian Journal of Plant Pathology 24 (2), 117-124
Abstract: A combination of geographical isolation and effective quarantine practices has excluded many serious pathogens of trees from Australia. The international trade in untreated wood and wood products, including dunnage, has increased the likelihood of the introduction of exotic pathogens and decay fungi and their becoming established and deleteriously affecting the current relatively healthy status of Australia's native and plantation forests, and amenity trees. Forest pathogens such as Heterobasidion annosum, Fusarium circinatum, Bursaphelenchus xylophilus, Puccinia psidii, and Phellinus pini are considered serious threats to plantation forests in Australia. The potential impact, if the more serious exotic pathogens of forests were to be introduced, would not only be the loss of a few seasons' crops, but also the loss of decades of effort and investment in plantations, as well as irreparable damage to the native biota and wood resources. Effective quarantine policies and procedures are necessary to prevent the entry of these pathogens into Australia.

La combinaison de l'isolement géographique et de procédures de quarantaine efficaces ont empêché la propagation de plusieurs importants agents pathogènes des arbres en Australie. Le commerce international du bois et des produits du bois non traités, y compris le fardage, a augmenté la vraisemblance que des agents pathogènes exotiques et des champignons de carie soient introduits, s'établissent et détériorent le relativement bon état de santé des forêts australiennes indigènes et issues de plantations, et des arbres d'agrément. Des agents pathogènes forestiers tels que l' Heterobasidion annosum, le Fusarium circinatum, le Bursaphelenchus xylophilus, le Puccinia psidii et le Phellinus pini sont considérés comme des menaces sérieuses pour les plantations forestières en Australie. S'il advenait que les agents pathogènes les plus menaçants soient introduits, l'impact potentiel ne se limiterait pas à la perte de quelques récoltes, mais s'étendrait à la perte de dizaines d'années d'efforts et d'investissements dans des plantations, et à des dommages irréparables au biotope et aux ressources ligneuses indigènes. Des politiques et des procédures de quarantaine efficaces sont nécessaires pour prévenir l'entrée de ces agents pathogènes en Australie.
