Survival and Growth of Planted Yellow-Cedar Seedlings and Rooted Cuttings (Stecklings) near Ketchikan, Alaska

Abstract

Abstract The survival and growth of yellow-cedar (Chamaecyparis nootkatensis) seedlings and rooted cuttings (stecklings) were monitored for 6 years after planting at three sites near Ketchikan in southeast Alaska to determine whether stecklings could serve as a suitable planting stock. Survival for both seedlings and stecklings was >85% at the three sites. Survival, final diameter, and final height differed by site but not by the use or absence of Vexar as protection from browsing by Sitka black-tailed deer (Odocoileus hemionus sitkensis). Vexar produced a lower rate of browsing but contributed to form problems (especially leaving trees leaning and prostrate on the ground). Seedlings had significantly greater diameters than stecklings even though they experienced a higher rate of browsing at one site. Differences in diameter and height likely were due to genetic variation rather than seedling or steckling stock type. Stecklings appear to be a suitable source of planting stock; when used for large-scale reforestation efforts, genetic considerations are essential. Planting recommendations for maximizing yellow-cedar establishment during regeneration are given.
