Invasive Species and Ecosystem Impact

The video discusses the impact of invasive species on ecosystems, highlighting the work of Margie Hunter, a member of the Tennessee Invasive Plant Council. It covers the identification and control of invasive plants, with examples like kudzu and Bradford pear. The video emphasizes the importance of understanding plant origins and their effects on local environments.

What are two examples of invasive species mentioned in the introduction?

• Tree of Heaven and Bradford pear

• Chinese privet and winter creeper

• Chinese privet and kudzu

• Winter creeper and English ivy

Why do invasive species often thrive in new environments?

• They have more predators in new environments

• They face less competition from native plants

• They are less adaptable to climate changes

• They have evolved with local pests and diseases

What is one of the main challenges Margie faces in her garden?

• Eradicating winter creeper and creeping monkey grass

• Growing ornamental plants

• Controlling the spread of native plants

• Identifying non-invasive species

How did the Bradford pear become invasive?

• It was introduced to control other invasive species

• It was thought to be sterile but crossbred with other cultivars

• It was used for medicinal purposes

• It was originally planted as a food source

What is the role of the Tennessee Invasive Plant Council?

• To promote the sale of non-native plants

• To categorize and manage invasive species

• To eliminate all non-native plants

• To plant more invasive species

What is a key factor in the spread of invasive species according to researchers?

• Their resistance to all diseases

• Their preference for urban areas

• Their ability to produce more seeds

• Their rapid spread causing environmental disruption

Why is it important to identify plants correctly in your garden?

• To ensure they grow faster

• To avoid confusing invasive species with similar-looking native ones

• To increase the aesthetic value of the garden

• To ensure they are all native species

What is a common misconception about buying plants in Tennessee?

• All plants sold are native

• All plants are sterile

• All plants are invasive

• All plants are ornamental

What is a recommended action if you find an invasive species in your yard?

• Let it grow to see its full potential

• Remove it while it's still young

• Plant more of the same species

• Ignore it as it will not spread

What is the impact of non-native plants on native ecosystems?

• They disrupt native plant and animal relationships

• They only affect urban areas

• They enhance biodiversity

• They have no impact
