5 invasive species are reshaping ecosystems faster than scientists predicted—here’s what you need to know
- This year, the invasive species burden has exploded, with new data showing that global economic damages from these biological invaders now exceed $423 billion annually, a fourfold increase since 1970.
- Among the top culprits: the spotted lanternfly has infested 17 U.S. states in just five years, decimating grapevines and triggering emergency quarantines for shipments and vehicles.
- Invasive species like the lionfish are expanding into deeper Atlantic waters, forcing fisheries to adapt as they outcompete native predators and consume juvenile commercial fish at alarming rates.
- Scientists warn that climate change is accelerating the spread of invasive species by warming waterways and extending breeding seasons—allowing Asian carp to invade the Great Lakes sooner than models predicted.
- Simple steps can help: cleaning hiking boots and boat hulls, and never releasing pets or plants into the wild, are your frontline defenses against introducing new invasive species to vulnerable habitats.
