Front

What is an invasive species?

Back

An invasive species is a non-native species that spreads rapidly in a new environment, often causing harm to native species and ecosystems.

Front

Why do invasive species grow quickly?

Back

Invasive species grow quickly because they have few or no natural predators in their new environment.

Front

What is a native species?

Back

A native species is a species that is originally from an area and has lived in the same place for a long time.

Front

What impact do invasive species have on native populations?

Back

Invasive species can lead to a decline or extinction of native populations by outcompeting them for resources.

Front

What is Kudzu?

Back

Kudzu is an invasive plant species in the southeastern United States that grows rapidly and can overtake native plants.

Front

How can invasive species be controlled?

Back

Invasive species can be controlled through methods such as chemical herbicides, physical removal, and introducing natural predators.

Front

What is the role of predators in controlling invasive species?

Back

Predators help control invasive species populations by keeping their numbers in check.

Front

What is an example of a chemical control method for invasive species?

Back

Applying herbicides in the spring is an example of a chemical control method for invasive species like Kudzu.

Front

What is the difference between native and non-native species?

Back

Native species are originally from a specific area, while non-native species are introduced from other regions or countries.

Front

Why is it important to manage invasive species?

Back

Managing invasive species is important to protect native biodiversity and maintain healthy ecosystems.
