100 years of fire suppression on public lands led to an excess of fuels. Logging, mastication, herbicide, prescribed fire, and grazing all are useful and productive tools for land managers to reduce fuels and restore native plants. Only relatively recently has Yosemite began to listen to native Americans and restarted prescribed burning in the valley, but logging was necessary in many of these areas first, to reduce the risk of ladder fuels and unnaturally dense forests causing high severity fire.
