Increasing the number of commissioners on the Montana Fish and Wildlife Commission from five to seven would add both better representation and clarity to hunters and anglers, supporters of a bill to do that said Tuesday. But opponents of House Bill 163 argued several points, from the additional cost of adding commissioners to whether the makeup of the commission excluded recreationists such as wildlife watchers. The governor-appointed and Senate-confirmed commission is the oversight board for Montana Fish, Wildlife & Parks. It is one of the highest profile nonelected bodies in the state, routinely tackling hot-button issues ranging from hunting, fishing and trapping regulations to land acquisitions and conservation easements for wildlife.
