Distribution details in Israel

Current pest situation evaluated by EPPO on the basis of information dated 2019: Present, restricted distribution
First recorded in: 1990
In Israel, A. confertiflora began to spread in the Shechem area in central Samaria during the mid-1990s. It is now widespread in Samaria, especially along roads and in cultivated areas, but also in Nature Reserves such as wadi Qana. The plant spread westwards and is now present in the Emek Hefer area (Sharon region), where 480 ha of riverbanks along the Alexander river are already heavily infested. The plant also spread eastward along wadi Tirza and has reached the Northern Jordan Valley. Additional foci were recently discovered along the Yarkon River, on the Carmel mount, in the Haifa region, in the southern part of Yizre'el valley in lower Galilee, and in the south near Gadera and in the Ashdod area.
