NAISMA’s Know Your Invasives campaign highlights invasive species throughout the year to raise awareness, educate the public, and encourage action.

In 2026, we are putting a spotlight on feral swine, one of the most destructive invasive mammals in North America. Feral swine damage forests, wetlands, crops, and infrastructure, prey on native wildlife, and spread diseases that threaten livestock, wildlife, and people. Their rooting and wallowing behavior degrades habitat, reduces water quality, and accelerates the spread of other invasive species, resulting in billions of dollars in economic losses and ongoing management challenges each year.

Through blogs, social media, webinars, and educational resources, we will explore why feral swine are so difficult to control once established, how early detection and reporting can make a critical difference, and what actions individuals, landowners, and communities can take to help prevent further spread and support coordinated management efforts.
