Which of the following is a mechanical approach to invasive species management?

A mechanical approach to invasive species management focuses on direct physical actions taken to remove or control the invasive species within an ecosystem. Physically removing the species from the habitat is a prime example of this method, as it involves tangible intervention to lessen the population of the invasive species. This can include activities like netting, trapping, or hand-pulling of the invasive species from the environment, thus directly reducing its presence and impact on the native ecosystem.

Implementing fishing quotas is more about regulating the exploitation of fish species, while using chemicals to target invasive species addresses the problem through chemical means rather than mechanical. Educating the public is a valuable strategy for long-term management and prevention but does not directly involve a mechanical method in confronting the invasive species themselves. Instead, it focuses on awareness and behavior change to prevent the introduction or spread of invasive species.
