The Joint ESENIAS and DIAS Scientific Conference and 9th ESENIAS Workshop "Species, ecosystems and areas of conservation concern under threat from the invasive alien species" was held on 3-6 September, 2019, in the city of Ohrid, Republic of North Macedonia. As part of conference Topic 1 (Invasive alien species traits and trends), Dr. Simeon Lukanov, member of the BIOGEA project team, presented a poster entitled „Distribution update for the invasive Pond Slider (Trachemys scripta) in Bulgaria with possible successful breeding in the wild“. Although Pond slider numbers are highest near human settlements and artificial ponds, elements of the agricultural infrastructure (e.g., irrigation canals, micro reservoirs, etc.) can be used by the animals as routes for expanding their range towards natural habitats. First data on the successful breeding of the species in Bulgaria were presented, with records on hatchlings in the wild in the southwest and southeast regions of the country.
