Today the Department of Land and Natural Resources' (DLNR) Division of Forestry and Wildlife (DOFAW) is involved in feral cattle eradication, organizing lotteries for special access feral cattle control. The hunt is not easy as animals have, over the generations, become smaller and wild. Similarly the local feral sheep have developed longer legs. Vehicles frequently hit cows congregated on roads enjoying the sun heated asphalt. The local legend of invisible cows on Mauna Kea originates from these crashes. Road signs warning against cows in darkness or fog are common.
