Cortaderia jubata poses a moderate phytosanitary risk to the endangered area with a moderate uncertainty. The species was trialled as a horticultural species over 100 years ago in France and Ireland, but more recently (2009) in the UK. However, there is no evidence to suggest this species has established or is commercially available in the PRA area. 

The likelihood of novel introductions occurring via seed or plant imports seems low given the current lack of commercial interest in this species.

 The pathway plants for planting is the main pathway evaluated for this species and scored a low likelihood of entry with moderate uncertainty. This is due to the species not being readily available in trade. The species is not currently established within the EPPO region.
