Survival and Growth of Planted Alaska-cedar Seedlings in Southeast Alaska
Seedlings of Alaska-cedar (Chamaecyparis nootkatensis (D. Don.) Spach) were planted on Etolin Island in southeast Alaska and measured annually for 5 years to evaluate their survival and growth on different types of sites and microsites. Seedling survival and growth were best where light exposure and soil drainage were adequate but were poor in heavy shade or soils with impeded drainage. Burned and unburned clear-cut sites supported the best survival, height growth, and diameter growth among site types. Shoot blight, caused by the fungus Apostrasseria sp., was common on sites where natural vegetative reproduction of Alaska-cedar was present nearby. Grazing by deer was common on some site types, but deer only consumed new growth and few seedlings were killed. Results illustrate that Alaska-cedar seedlings planted on productive sites may have good survival and early growth. Tree Planters' Notes 43(3):60-66:1992.
