Share An international research team with a Russian scholar onboard studied how to improve the system of early detection and response to the penetration of alien plant or animal species into new regions. Such species are commonly referred to as invasive and cause profound harm to the ecosystems they are introduced to. Today, scientists focus on developing measures and approaches to detect intruders at the earliest stages of their penetration into new territories. „In September 2019, Ljubljana (Slovenia) hosted DETECTION AND CONTROL OF FOREST INVASIVE ALIEN SPECIES IN A DYNAMIC WORLD international conference within LIFE ARTEMIS European project under the supervision of (Dr Maarten de Groot. Among other topics, they discussed early detection and prevention of the spread of invading species and the improvement of existing approaches. To reveal the challenges and development the potential of the early detection and rapid response system, we studied the cases of four alien species spreading in Europe – two animals (the grey squirrel and the emerald ash borer), a plant (the pokeweed or Phytolacca americana), and a phytopathogenic fungus (Geosmithia morbida) infecting walnut trees,“ said Natalia Kirichenko, a senior researcher at the School of Ecology and Geography of Siberian Federal University, and V.N. Sukachev Institute of Forest.
