SY24 Invasive Species Flashcard

Front

What is an invasive species?

Back

An invasive species is a non-native organism that, when introduced to a new environment, can cause harm to the ecosystem, economy, or human health.

Front

Why is early detection important in managing invasive species?

Back

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

Front

How do invasive species like the Asian Carp spread?

Back

They spread through accidental introduction, intentional release, or natural dispersal.

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

Why are Zebra Mussels a threat to native species?

Back

Zebra Mussels can outcompete native species for resources, introduce new diseases and predators, and lead to a decline in native populations.

Front

How can individuals help prevent the spread of invasive species?

Back

By avoiding the release of exotic pets and plants, cleaning boats and equipment before moving them, and being cautious with non-native species.

Front

What are the economic impacts of invasive species?

Back

Invasive species can cause damage to crops, fisheries, and infrastructure, increasing costs for control and management.

Front

What is the role of ecosystems in managing invasive species?

Back

Healthy ecosystems can be more resilient to invasions, but invasive species can disrupt these systems.

Front

What is the difference between native and invasive species?

Back

Native species are organisms that naturally occur in a specific area, while invasive species are non-native and can disrupt local ecosystems.

Front

What is the significance of biodiversity in relation to invasive species?

Back

Biodiversity helps ecosystems resist invasions and recover from disturbances, making it crucial for ecosystem health.
