Which of the following is a common task for AIS inspectors during inspections?

The primary role of AIS (Aquatic Invasive Species) inspectors is to monitor and prevent the spread of invasive species in water bodies. This task is crucial because invasive species can significantly disrupt local ecosystems, outcompete native species, and degrade water quality. Inspectors typically focus on identifying and assessing the presence of these invasive species in various water bodies to prevent their introduction and spread.

Checking for the presence of invasive species includes both visual inspections and sometimes the use of equipment to sample water or substrate to identify any organisms that may pose an ecological threat. This proactive approach is essential for managing biodiversity and protecting aquatic resources.

While other tasks mentioned, such as applying pesticides, conducting fish population surveys, and assessing the health of aquatic plants, are important within the field of aquatic management and conservation, they are not primary responsibilities of AIS inspectors. Instead, these activities are generally conducted by other specialists or agencies involved in aquatic research, wildlife management, or environmental protection.
