AP®︎ Environmental Science: Topic 9.8 Flashcards

A non-native species whose establishment or spread threatens native species and causes ecological harm

A species that occurs naturally in a region without human introduction

A species occurring outside its native range because of intentional or accidental human activity

A non-native species that has developed a self-sustaining population in its new environment

The sequence of transport, introduction, establishment, spread, and ecological impact in a new region

Escape from the predators, herbivores, parasites, and pathogens that controlled a species in its native range

Blocking transport or release by managing routes such as trade, ballast water, boats, firewood, pets, and nursery stock

Monitoring for new invaders and immediately eradicating or containing them while populations remain small and localized

Complete elimination of an invasive species from a defined area

Preventing an invasive species from spreading beyond its current distribution

Reducing an invasive species’ abundance or ecological impact without necessarily eliminating it

Repeatedly maintaining an established invasive population at a lower level when elimination is not feasible

Direct removal or killing through methods such as pulling, cutting, trapping, hunting, barriers, or harvesting

Using toxic substances such as herbicides, insecticides, or molluscicides to reduce an invasive population

Using a living organism or biological agent to reduce an invasive population

Introducing a tested natural enemy from an invasive species’ native range to suppress it

Changing habitat conditions to disadvantage an invader while restoring conditions, vegetation, or competitors that favor native species

Combining prevention, monitoring, removal, selected controls, habitat restoration, and follow-up assessment
