  3. Treatment duration and time since disturbance affect vegetation development in a young California red fir plantation

    The density and development of greenleaf manzanita, snowbrush, goldenbush (rabbitbrush), and graminoids were evaluated in a young California red fir plantation in northern California from 1986 through 1995. Manual grubbing and herbicides created treatment regimes that lasted for 3 to 6 years and vegetation recovery times of 4 to 10 years. The duration and timing of the...
