RFFI is testing approaches to managing hardwoods without using herbicides in the Usal Redwood Forest. The undesirable hardwoods grow quickly and shade out Douglas fir and redwood trees, thus slowing their growth. RFFI has taken up the challenge of vegetation management without chemicals. In this clip, you will see them experimenting by removing bark and 'girdling' tanoak trees to limit their growth.
