First report of Euphorbia davidii in Türkiye
Euphorbia davidii (Euphorbiaceae) is an invasive alien plant in the EPPO region and was added to the EPPO A2 list in 2025. It is native to North America (USA and Mexico) and has shown negative impacts on crop yields in Argentina where it was introduced in the 1980s. It is recorded in a number of EPPO countries where it is reported as established, transient and in some countries with an unclear status. A new record for E. davidii is reported from Türkiye from the Sakarya province in 2026. Here, the species occurs along roadsides. Further monitoring of the population is required to ensure that it does not spread and cause damage in agricultural areas surrounding the current population.
