Survival and Growth of Planted Conifers on the Dead Indian Plateau East of Ashland, Oregon

摘要

Survival and growth of Douglas-fir, white fir, and ponderosa pine seedlings were studied in experimental plantations. Both bare-root and containerized seedlings were tested in the open and under partial-cut canopy. Some were caged, some were watered, and some fenced. Survival of all species was much better under the partial-cut canopy than in the open, where ponderosa pine survived better than Douglas-fir or white fir. Containerized Douglas-fir and white fir seedlings grew best under the canopy. Underplanting is recommended on the Dead Indian Plateau.
