Aquatic Invasive Species
Measuring what matters: Shared goals
Preventing the introduction of new nonnative species is the most cost-effective approach to minimize future threats from AIS. Prevention activities aim to reduce the uptake, movement and introduction of nonnative species, and may be applied to any of the pathways that introduce AIS into the Great Lakes basin: trade in live organisms, recreational activities, shipping, and canals and waterways.
Reporting on regional consistency in regulatory policies and prevention programs used to ensure boaters take specific actions to reduce the risk of spreading aquatic invasive species.
Assessing regional consistency in the regulatory policies to restrict the introduction and spread of priority aquatic invasive species.
Early detection (i.e., monitoring) and response programs are intended to detect new nonnative species early while populations are still localized. Early detection increases the likelihood that work to contain, control, and ideally eradicate new populations will be effective. A comprehensive basinwide approach is needed to coordinate and guide detection and response efforts.
Reporting on locations in the Great Lakes where surveillance for aquatic invasive species is a priority.
More than 185 nonnative species are established in the Great Lakes, some of which are considered invasive and are causing ecological and/or economic damage. While significant progress is being made to prevent the introduction and establishment of new AIS, damaging populations of AIS that already exist should be managed to reduce their negative impacts.
Aquatic invasive species (AIS) have an impact on nearly every beneficial aspect of the Great Lakes. Stakeholders recognize that effective AIS prevention and control is needed to protect coastal industries, water quality, ecosystems, and human health. Federal, state, and provincial agencies are making binational commitments to protect the Great Lakes from harmful AIS. Working with representatives from these agencies and other partners, Blue Accounting is tracking progress toward preventing AIS introduction and spread as well as minimizing the harmful impacts of already-established AIS.
What we do
Blue Accounting tracks progress on efforts to: stop species introduction and spread through priority pathways including live trade and recreational boating; implement a regionally coordinated program to detect new species; and control populations of harmful invasive species across the region.
Through Blue Accounting, decision-makers will understand how current strategies are addressing regional AIS prevention and control goals.
What we measure
Blue Accounting reports relevant data on aquatic invasive species management, focusing on efforts to prevent the introduction of AIS, detect and respond to any new AIS, and control existing AIS populations. Data are directly measured by governments and partners.
