Heracleum mantegazzianum(HERMZ)
Distribution details in Slovenia
Current pest situation evaluated by EPPO on the basis of information dated
2013: Present, few occurrences
EPPO Reporting Service (2013/158) : It is considered that this plant escaped from the Ljubljana Botanical Garden in the 1980s to the centre of Ljubljana and spread along railways. By 2011, the H. mantegazzianum population
had already spread over 3 ha, but most plants were only confined to a stretch of 0.8 ha along railways.
Eradication started in 2011. After three years during which H. mantegazzianum was removed from the core zone of distribution and three marginal stands, the number of plants with the potential to flower was reduced significantly.
