SY24 Invasive Species Flashcard

Front

What are invasive species?

Back

Invasive species are non-native organisms that spread widely in a new environment, often causing harm to native species, ecosystems, and human activities.

Front

How do invasive species spread?

Back

Invasive species can spread through various means such as accidental introduction, intentional release, natural dispersal, and human activities.

Front

What is early detection in the context of invasive species?

Back

Early detection refers to identifying invasive species as soon as they enter a new environment, allowing for timely management and control measures.

Front

Why is early detection important?

Back

Early detection is crucial because it ensures that control measures are less costly and more likely to be successful.

Front

What are some methods to manage invasive species?

Back

Methods include early detection and rapid response, control and eradication efforts, and prevention of further spread.

Front

What challenges do national parks face in managing invasive species?

Back

Challenges include limited resources, difficulty in eradicating established populations, and potential harm to native species and ecosystems.

Front

How can individuals help prevent the spread of invasive species?

Back

Individuals can help by cleaning boats and equipment before moving them, avoiding the release of exotic pets and plants, and being cautious when purchasing non-native species.

Front

What is the impact of invasive species on biodiversity?

Back

Invasive species can reduce biodiversity by outcompeting native species for resources, leading to declines or extinctions of native populations.

Front

What is the role of public education in managing invasive species?

Back

Public education raises awareness about the risks of invasive species and encourages responsible behaviors to prevent their spread.

Front

What is a natural predator in the context of invasive species?

Back

A natural predator is a species that preys on invasive species, potentially helping to control their populations.
