Effect of auger planting on survival and growth of Douglas-fir on droughty sites

Creator:

Hobbs, Stephen D. and Oregon State University. Forest Research Laboratory

Abstract:

Two-year-old Douglas-fir bareroot seedlings were hoe- and auger-planted on droughty south and southwest aspects in southwest Oregon. After 2 years, no differences in height, diameter, or seedling biomass could be detected. Auger-planted seedlings survived significantly better on the southwest aspect.

EFFECT OF AUGER PLANTING ON SURVIVAL AND GROWTH OF DOUGLAS-FIR ON DROUGHTY SITES S. D. HOBBS ABSTRACT
Survival of natural and planted seedlings under a shelterwood in southwest Oregon

Creator:

Helgerson, O. T., Wearstler, Kenneth A., Bruckner, Werner K., and Oregon State University. Forest Research Laboratory

Abstract:

The effects of naturally shaded microsites on survival and height growth of natural and planted seedlings were evaluated after an initial shelterwood harvest in the eastern Siskiyou Mountains of southwestern Oregon. After 2 years, the probabilities of survival for planted Douglas-fir (84 percent) and ponderosa pine (56 percent) were significantly...
