Marco Polo argali, a threatened species under the US Endangered Species Act, are prized by trophy hunters for their spiralling horns that can grow more than 150cm and their stocky bodies that can weigh more than 130 kilograms.

Schubarth sought to create an even more valuable species, according to prosecutors. Sheep with larger horns and bodies are worth more to hunters, including at private shooting reserves, where hunters pay to pursue captive game.

In 2014, Schubarth petitioned the state of Montana to allow Marco Polo argali into the state, but officials denied the request due to the potential for disease transmission to native species and the risk of the species establishing feral populations.

But Schubarth agreed to a contract with a cloning facility in 2015, and by late the following year, he had 165 cloned embryos. He implanted embryos in his ewes and in May 2017 bred a male argali, who he named Montana Mountain King.

In the following years, Schubarth bred Montana Mountain King’s semen with other ewe species, creating more hybrid sheep that he sold to captive hunting facilities, mainly in Texas. To do so, he bought Rocky Mountain bighorn sheeps’ testicles, despite Montana prohibiting trade of game animals.

Schubarth sold 11 sheep with one-quarter of Montana Mountain King’s genetics for $US13,200 total to two people in Texas, prosecutors said. He also traded one of that sheep’s offspring for $US10,000 and sold dozens of straws of its semen to breeders in other states.

Schubarth and his accomplices illegally moved ewes across state lines to inseminate them and falsely declared the sheep to be different species to get state veterinary certificates that would permit them to transport the animals. His manoeuvre lasted until October 2022, court documents allege.

“His actions threatened Montana’s native wildlife species for no other reason than he and his co-conspirators wanted to make more money,” Jesse Laslovich, US Attorney for the District of Montana, said in a statement.

Schubarth surrendered his illegal animals to authorities, and their meat was donated to Montana families in need, court documents said. Montana Mountain King is in the custody of the US Fish and Wildlife Service, according to Matthew Nies, a spokesman for the Justice Department.

As part of Schubert’s sentencing, US District Court Judge Brian Morris ruled that Schubarth cannot breed big game stock for three years.

Two of Schubarth’s co-conspirators were each sentenced to a year of probation in the scheme last year.
