1. What is an invasive species?
a) A native species that has adapted to new environments
b) A species that spreads rapidly and causes harm to ecosystems, economies, or human health
c) A species that is deliberately introduced for ecological restoration
d) A species that is restricted to a specific geographic area
Answer: b) A species that spreads rapidly and causes harm to ecosystems, economies, or human health

2. Which of the following is a common method for managing invasive species?
a) Encouraging their spread
b) Eradication, control, and containment
c) Ignoring their presence
d) Promoting their use in agriculture
Answer: b) Eradication, control, and containment

3. What is “biological control” in the context of invasive species management?
a) Using chemicals to kill invasive species
b) Introducing natural predators, parasites, or pathogens to manage invasive species
c) Restricting human access to areas invaded by these species
d) Removing native species to reduce competition
Answer: b) Introducing natural predators, parasites, or pathogens to manage invasive species

4. Which of the following is an example of a mechanical control method for invasive species?
a) Using herbicides to kill invasive plants
b) Releasing biological agents to control population
c) Physically removing invasive plants or animals from the area
d) Using traps to capture invasive species
Answer: c) Physically removing invasive plants or animals from the area

5. What is “integrated pest management” (IPM)?
a) A method that relies solely on chemical treatments to manage invasive species
b) Combining multiple control methods, including biological, mechanical, and chemical, to manage invasive species
c) Ignoring invasive species management and focusing on habitat restoration
d) Using only natural predators to control invasive species
Answer: b) Combining multiple control methods, including biological, mechanical, and chemical, to manage invasive species

6. What is the main objective of early detection and rapid response (EDRR) in invasive species management?
a) To monitor existing invasive species populations
b) To quickly identify and address new invasive species before they become established
c) To promote the spread of invasive species
d) To increase the public’s awareness about invasive species
Answer: b) To quickly identify and address new invasive species before they become established

7. Which of the following is a potential negative impact of invasive species on native ecosystems?
a) Increased biodiversity
b) Enhanced ecosystem services
c) Displacement of native species and disruption of ecological balance
d) Improved soil fertility
Answer: c) Displacement of native species and disruption of ecological balance

8. What role does public education play in managing invasive species?
a) It is not relevant to invasive species management
b) It helps increase awareness about invasive species and encourages prevention and reporting
c) It focuses solely on promoting the sale of invasive species
d) It reduces the need for active management efforts
Answer: b) It helps increase awareness about invasive species and encourages prevention and reporting

9. Which of the following is a common challenge in managing invasive species?
a) Lack of funding
b) Overabundance of native species
c) High biodiversity in the affected area
d) Low public interest
Answer: a) Lack of funding

10. What is “prevention” in the context of invasive species management?
a) Developing new invasive species
b) Taking measures to prevent the introduction and spread of invasive species
c) Allowing invasive species to establish before managing them
d) Focusing solely on controlling existing populations
Answer: b) Taking measures to prevent the introduction and spread of invasive species
