What signals a successful AIS management strategy?

A successful Aquatic Invasive Species (AIS) management strategy is indicated by a reduction in the spread and populations of invasive species over time. This outcome is critical because the primary goal of AIS management is to minimize the impact of invasive species on ecosystems, which includes protecting native species and habitats. When the populations of invasive species decrease, it signifies that management efforts, such as monitoring, prevention, and control measures, are effectively working. This strategy not only supports biodiversity but also helps maintain the health of aquatic ecosystems.

While factors like increased aquatic tourism, higher fish catch rates, and more state funding for water projects can be positive and suggest a thriving water resource management plan, they do not directly reflect the effectiveness of AIS management. For instance, tourism and fishing may rise due to various factors unrelated to the control of invasive species, such as improvements in overall water quality or recreational facilities. Hence, the most direct and measurable signal of a successful AIS management strategy is indeed the reduction of invasive species populations over time.
