Dedicated funding for efforts that block pathways of movement for AIS prevents their introduction and spread.

Preventing the introduction of new non-native species is the most cost-effective approach to minimize future threats from AIS. Prevention activities aim to reduce the risk of uptake, movement and introduction of non-native 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.

Annual GLRI Funding for Prevention

Chart showing annual funding trends for AIS prevention activities.

The proportion of GLRI funding directed toward AIS prevention activities between FY2011 and 2015 was relatively consistent, hovering around 20 percent. The greater funding total in FY2010 is reflective of the higher overall funding amount for GLRI that year, as well as the inclusion of 14 projects that were collectively awarded a total of $10,475,225 to study ballast water treatment technologies and methods for preventing the spread of AIS through the shipping pathway.

Annual GLRI Prevention Funding for Pathways

Chart showing annual funding trends for prevention activities in four primary pathways: organisms in trade, recreational boating, shipping, and canals.

Prevention activities are imperative to reducing movement of AIS. These efforts include developing and testing prevention technology for ballast water in the shipping pathway, coordinated boat wash and inspection events in the recreational boating pathway, conducting risk assessments for potential AIS in the trade in live organisms pathway, and designing effective barriers to limit natural spread of species in the canals pathway.

GLRI funding is awarded to multiple levels of government and a variety of public and private entities that are involved in programs and projects to prevent the introduction of AIS.

Funding sources for AIS work are varied and include grant programs administered by non-profit organizations, private sector funding initiatives, and base agency budgets set annually through state, provincial, and federal legislatures. Federal funding in the U.S. includes the Great Lakes Restoration Initiative (GLRI), which was established and funded in 2010 to address the major threats to Great Lakes ecosystems and drinking waters, including AIS.

GLRI data presented here is derived from the U.S. Environmental Protection Agency’s (U.S. EPA)Environmental Accomplishments in the Great Lakes (EAGL) database of federally-dispersed GLRI funds (i.e., FY2010-2015 funding dispersed directly to recipients for project implementation), including associated data metrics and project descriptions. A set of search terms and functions relevant to AIS research and management was used to identify AIS projects within the EAGL database. The information presented here does not include funding data for invasive carp projects. For complete information about Asian Carp Action Plan funding and projects, visit

The information presented here builds on a database of AIS funding originally developed by the Great Lakes Panel on Aquatic Nuisance Species.
