Final answer:
To reduce the arrival of new invasive species, implementing a monitoring program, having strict regulations and screening processes, and conducting risk analyses are important steps. Educating people about native biodiversity is also crucial.
Step-by-step explanation:
The arrival of new invasive species can be reduced through various measures. One approach is to implement a monitoring program that involves continuous surveillance for unusual plants or animals. This can be done by enlisting the help of the public to be on the lookout and report any sightings to the relevant authorities. Another strategy is to have strict regulations and screening processes in place to prevent the intentional introduction of invasive species. Risk analyses can be conducted to identify species that have a high probability of becoming invasive and restrict their entry. Additionally, efforts should be made to educate people about the value of native biodiversity and the risks associated with invasive species.
