Development of a mixed shrub-tanoak-douglas-fir community in a treated and untreated condition. Forest Service research paper

Technical Report ·
OSTI ID:557571

On a medium site in northern California, a tanoak-mixed shrub community was given several treatments (manual release two and three times, a combination chainsaw and cut surface herbicide treatment, two foliar herbicides, and a tank mix of the two herbicides) to study its development in both a natural (control) and treated condition. The herbicides were 2,4-D, Garlon 3A, and Garlon 4, each applied two times. Survival of planted Douglas-fir seedlings was recorded for 11 years and growth was quantified for 9 years after the last treatment application. In addition to Douglas-fir, data are presented individually for the two most abundant species (tanoak and snowbrush), for greenleaf manzanita, and for the hardwood tree and shrubs combined. The treatment response data, cost information, and plant community relationships provides the forest land manager with knowledge on how to attain some specific plant communities in the future, and their developmental potentials.
