Investments made in the Great Lakes region to advance AIS management strategies include direct funding support, capacity for education and outreach, on-the-ground and in-the-water actions, and regulatory enforcement. This site will be updated to reflect the diversity of investments by researchers, managers, and communicators to prevent, detect, and control AIS across the region as Blue Accounting continues to identify and collect this information. Patterns of investment can be analyzed to see what AIS management strategies are being resourced and to identify opportunities where additional resources may be needed to achieve regional AIS goals.

AIS GLRI Funding Overview

Annual Funding

Graph showing annual trends in the amount of funding dedicated to aquatic invasive species through the GLRI funding program.

$1.9 billion has been dispersed as GLRI funding between fiscal years 2010-2015.  In these years, the proportion of funding awarded to AIS programs and projects has remained consistent, fluctuating between 10 to 13 percent of the total funding appropriated for GLRI.

Annual Pathway Funding

Aquatic invasive species move into and throughout the Great Lakes region via a variety of pathways. Funding for the four major pathways of invasion has shifted annually based on the funding priorities of federal agencies.

Annual Goal Funding

Reactive activities, including control of established species populations, have historically received a larger amount of funding compared to proactive activities such as prevention, surveillance, and response. Further information about funding for each of these goals is available in each of the goal cards.

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.
