Have you ever heard of Japanese knotweed, red-eared slider, or Himalayan balsam? They might sound exotic, but in reality, they are invasive alien species.
They were brought here by humans – intentionally or unintentionally – but today they threaten our native plants, animals, and entire ecosystems.
What exactly are invasive species?
They are plants, animals, or microorganisms that are not naturally present in our environment. Because they have no natural predators, they reproduce quickly and displace the native species. Their spread threatens biodiversity, harms agriculture, the economy, and sometimes even human health.
Some common invasive species in Slovenia:
Japanese knotweed – a strong plant that overgrows everything in its path, even asphalt
Himalayan balsam – spreads rapidly along watercourses and crowds out native plants
Red-eared slider – a popular pet turtle that poses a threat to native species when released into the wild
Asian tiger mosquito – spreads diseases and thrives in warmer climates
Pumpkinseed sunfish – a decorative fish that disrupts freshwater ecosystems
How can we help?
Respect nature – don’t pick plants or release animals into the wild
After hikes or trips into nature, clean your shoes and equipment – seeds can easily spread via muddy soles, bikes, or boats
Never release aquarium fish, turtles, or other pets into the wild – they can become a serious threat to the environment
