Transgenic trees

Genetically modified trees (transgenic trees) are not yet authorised for cultivation in Europe. However, in some countries field trials are being carried out, which requires a detailed consultation of this specific form of genetically modified plants, in particular with regard to environmental risk assessment requirements. The report provides an overview of the state of development of transgenic forest trees with regard to modified tree species and genetically modified properties such as herbicide tolerance. Environmental risk assessment challenges are addressed in the context of the current licensing system in the EU. Possible effects of the cultivation of transgenic trees on the forest in Austria are discussed, both with regard to the functions of the forest (use, protection, welfare and recreation function) as well as on the objectives of nature conservation.
