WSSA Calculates Billions in Potential Economic Losses from Uncontrolled Weeds (May 4, 2016)
Weed Science Society of America.
What losses would corn and soybean growers experience if they were forced to eliminate herbicides and other control techniques from their weed management toolbox? A team of experts with the Weed Science Society of America (WSSA) found that in the U.S. and Canada, about half of both crops would be lost to uncontrolled weeds, costing growers about $43 billion annually.

The Economic Cost of Large Constrictor Snakes (Jan 2012; PDF | 687 KB)
DOI. Fish and Wildlife Service.
The U.S. Fish and Wildlife Service, in partnership with many organizations, has spent more than $6 million since 2005 finding and applying solutions to the growing problem of Burmese pythons and other large invasive constrictor snakes in Florida. For more information, see Rule Making to List Four Constrictor Snake Species Under the Lacey Act: Final Economic Analysis (Jan 12, 2012; PDF | 687 KB).

Great lakesResearch Show Invasive Species Cost the Great Lakes Millions: New Paper Assigns Dollar Figure to Effects of Shipborne Invaders (Mar 29, 2012)
University of Notre Dame.
Researchers assigns a dollar figure on the cost to the Great Lakes from invasive species that originate in the ballast water of ocean-going vessels. For the U.S. waters, median damages aggregated across multiple ecosystem services were $138 million per year, and there is a 5% chance that for sportfishing alone losses exceeded $800 million annually. For information, see the journal article Ship-borne Nonindigenous Species Diminish Great Lakes Ecosystem Services.
Study Finds that Local Government, Home Owners Are Paying for Damages Caused by Non-native Forest Insects (Sep 9, 2011)
USDA. FS. Northern Research Station.
Non-native, wood-boring insects such as the emerald ash borer and the Asian longhorned beetle are costing an estimated $1.7 billion in local government expenditures and approximately $830 million in lost residential property values every year, according to study by a research team that included scientists with the U.S. Forest Service, Northern Research Station. This study provides the most comprehensive estimates of the costs of non-native forest insects that are currently available for the U.S.
One study estimates that the total costs of invasive species in the United States amount to more than $100 billion each year. (Pimentel et al., 2005)
Invasive species impact nearly half of the species currently listed as Threatened or Endangered under the U.S. Federal Endangered Species Act. (Pimentel et al., 2005)
