Officials investigating a History channel television show called "American Jungle" were unable to prove any laws were violated during filming.

The state Department of Land and Natural Resources began investigating after an episode aired in November raised concerns that unpermitted hunting was taking place on state land on Hawaii island.

The department said Thursday the investigation was unable to prove that producers filmed on state land or that any marine or wildlife laws were violated, West Hawaii Today reported.

The show depicts "clans" fighting over access to territorial hunting grounds, and using knives and spears to take down prey. DLNR Chairman William Aila and Gov. Neil Abercrombie have criticized how the show portrays hunting in Hawaii.

The first episode, broadcast Nov. 10, shows hunters using spears and dogs to hunt a cow, the department said, even though it’s illegal to hunt cattle without a feral cattle control permit. Another episode showed hunting at night, which also is illegal.

"American Jungle" creator T’Jaye Forsythe said reactions to the show have varied. Reality television is a mix of fiction and reality, he said.
