Trained dogs detected invasive plant species in Germany with 75% accuracy

Invasive alien species (IAS) are one of the main causes of biodiversity loss worldwide. A study published Nov. 4, 2026, in the journal PLOS One by Annegret Grimm-Seyfarth at Helmholtz-Centre for Environmental Research—UFZ, Germany, and colleagues found that with training, volunteer dog-handler teams could locate invasive species in the wild with 75% accuracy.
