That has allowed forests to become four to seven times more densely wooded than they once were, Safford said.
Fire scientists advocate more deliberate burning at low-to-moderate severity to clear vegetation that makes forests susceptible to big fires.
Susan Britting, executive director of one of the groups, Sierra Forest Legacy, acknowledged any cutting triggers skepticism because loggers historically took the largest, most marketable trees.
But she said thinning trees up to a certain diameter is acceptable, though she prefers prescribed burning.
Homeowners are anxious prescribed fires will jump perimeters and destroy houses.
