All known feral swine have been eliminated from Colorado thanks to a near 15-year state and federal partnership comprised of the U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) Wildlife Services (WS), the USDA Forest Service (FS), Colorado Parks and Wildlife (CPW) and the Colorado Department of Agriculture (CDA). The partnership formed in the early 2000s as a task force to manage invasive feral swine, which root up crops and pastures causing billions in damage nationwide each year. Feral swine also spread disease to livestock, wildlife and humans. Ground-nesting birds and other wildlife are easy prey for feral swine. And the swine put native wildlife at risk by competing for resources and destroying habitats and ecosystems. 

You can help keep Colorado free of feral swine:

• Spread the word that in Colorado it’s illegal to possess, transport or release feral swine, wild swine species or hybrids.
• Report sightings of feral swine or transportation activities to USDA Wildlife Services at 1-866-4-USDA-WS (1-866-487-3297) or Colorado Parks and Wildlife at 303-297-1192.
• Get more information at the National Feral Swine Damage Management Program.

On Tuesday, April 24, Gov. John Hickenlooper signed the Mussel-Free Colorado Act into law in a short ceremony at the Colorado State Capitol Building in Denver. The new law provides a stable funding source of $2.4 million for Colorado Parks and Wildlife's Aquatic Nuisance Species Program for 2019 and beyond.

The Japanese Beetle was discovered in Mesa County in the summer of 2022. The Colorado Department of Agriculture has been working in partnership with local stakeholders to eradicate the pest and prevent its spread into additional areas of Colorado.
