EPPO Express PRA for Ehrharta calycina
Ehrharta calycina poses a moderate phytosanitary risk to the endangered area with a moderate uncertainty. A moderate risk score has been given based on the low likelihood of entry, coupled with the high risk of establishment and high negative impacts on biodiversity and ecosystem services. The species occurs in Portugal, Spain and Tunisia and there is some circumstantial evidence the species has spread within the region. Compared to California and Australia, the occurrences in the EPPO region are relatively recent and therefore the species may still be in the lag phase (i.e. the full extent of the invasion may not yet be realised).
