Despite having eradicated mountain lions over 100 years ago, New Hampshire’s legal code lists mountain lions as a game animal. There is no current season for mountain lion, so it is effectively illegal to hunt them.
One could easily argue that mountain lions should be listed as endangered in New Hampshire. However, New Hampshire's threatened and endangered species list apply only to “species of native wildlife whose continued existence as a viable component of the state's wild fauna is determined to be in jeopardy”. Unfortunately, the state does not consider mountain lions to fall within this categorization.
