Invasive Species Basics
What is the definition of an invasive species?
An invasive species is a non-native species that causes harm to the environment, economy, or human health.
How can invasive species impact the biodiversity of an ecosystem?
They can outcompete and displace native species, leading to a loss of biodiversity.
Identify the invasive species that kills floral and fruit trees by sucking their sap
Spotted Lanternfly
Provide one method used to control the spread of invasive species
Biological control, chemical control, or mechanical control.
How can individuals help prevent the spread of invasive species?
Clean equipment and gear, avoid releasing pets into the wild, and be aware of local regulations.
Provide one way invasive species are typically introduced to new environments.
Through human activities such as trade, travel, and accidental releases.
Explain one way invasive species can alter ecosystem processes.
They can disrupt nutrient cycles, change fire regimes, or modify water flow.
Name one invasive plant species that is common in the Southeastern United States, originating from China.
Kudzu.
How can early detection and rapid response help manage invasive species?
It allows for the timely implementation of control measures before the population becomes too large.
Why is it essential to educate the public about invasive species?
Increased awareness can lead to better prevention and early detection efforts.
Why do invasive species often outcompete native species?
They may lack natural predators or diseases in the new environment.
How do invasive species contribute to the decline of native species?
By predation, competition for resources, or introducing diseases.
Which invasive species brought to the United States for pet trade?
The Burmese Python.
What is the role of community involvement in invasive species management?
It can help with early detection, control efforts, and raising awareness.
Give an example of a campaign or initiative aimed at raising awareness about invasive species.
National Invasive Species Awareness Week (NISAW) or local invasive species awareness campaigns.
Name one characteristic that makes a species more likely to become invasive.
High reproductive rates, adaptability, or lack of natural predators.
Give an example of an ecosystem service that may be negatively impacted by invasive species.
Pollination, water purification, or soil fertility.
Identify the invasive species that attack the Ash trees.
Emerald Ash Borers, or EAB.
Give an example of an unsuccessful invasive species management program.
The population control of the emerald ash borer.
How does international cooperation contribute to the prevention of invasive species?
It helps in monitoring and controlling the movement of species across borders.
What is the difference between an invasive species and a non-native species?
Not all non-native species become invasive; invasive species specifically cause harm to the new environment.
Describe the economic impacts of invasive species on agriculture.
Loss of crops, increased control costs, and damage to infrastructure.
Which invasive species arrived to the United States in the 1980’s via European ships? (Hint: this species was the focus of an assignment we did in class.)
The Zebra Mussel.
Explain why it’s so difficult to control the spread of the emerald ash borers.
The process involves removing infected trees. However, since there are so many infected by the EABs, it makes it impractical and costly to attempt this method.
Name one international treaty or agreement focused on preventing the spread of invasive species.
The International Plant Protection Convention (IPPC) or the International Maritime Organization (IMO) Ballast Water Management Convention.
