Colorado has become the first state to eliminate its invasive feral hog population.
According to AgWeb, the state ramped up efforts in 2005 and encouraged hunters and landowners to shoot the animals while also intentionally relaxing regulations. The state also began live trapping and euthanizing the hog and encouraged the public to call in hog sightings. The state also looked for wild hog DNA in water samples.
Fifteen years after these measures were put in place, the population has been eliminated.
