All Flashcards
Define invasive species.
Non-native species that cause harm to the environment, economy, or human health.
What is Integrated Pest Management (IPM)?
Using a combination of different control methods for effective and sustainable results.
Define 'Early Detection and Rapid Response' (EDRR).
Taking action as soon as new invasive species are detected.
What is biological control?
Introducing natural predators, pathogens, or competitors to control invasive species.
Define habitat modification.
Altering the environment to favor native species and make it less suitable for invasive species.
What is chemical control?
Using pesticides or other chemicals to kill or inhibit the growth of invasive species.
Define physical removal.
Manually removing invasive species individuals or populations.
What is a non-native species?
A species living outside its native distributional range, which has arrived there by human activity, either deliberate or accidental.
Define quarantine.
Isolation to prevent the spread of something considered dangerous, like invasive species.
What are control measures?
Methods used to manage or eradicate invasive species once they have been introduced.
Why is prevention key for invasive species?
It's the most effective and cost-efficient way to deal with invasive species, preventing problems from starting.
Explain the importance of monitoring and early detection.
Regularly checking for new invasive species allows for rapid response, minimizing their potential impact.
Why is public education important in invasive species control?
Raising awareness encourages public participation in prevention and control efforts.
Why is IPM important?
It helps avoid over-reliance on single control methods and minimizes negative impacts on the environment.
Describe the ecological impacts of invasive species.
Outcompete native species, alter ecosystem processes, reduce biodiversity, and change food webs.
Describe the economic impacts of invasive species.
Damage to agriculture, forestry, recreation, costly control efforts, and infrastructure damage.
Describe the human health impacts of invasive species.
Increased risk of new diseases and potential for other health-related problems.
What are the steps for preventing invasive species introduction?
Quarantine and inspection of imported goods, control of pathways, and public education.
Outline the process of Integrated Pest Management.
Identify the pest, monitor the population, determine action thresholds, implement control tactics, and evaluate effectiveness.
What are the steps involved in biological control?
Research potential agents, test for host specificity, introduce the agent, and monitor its impact.
