Current Practices for Growing Whitebark Pine Seedlings at the U.S. Department of Agriculture, Forest Service, Coeur d’Alene Nursery
The USDA Forest Service, Coeur d’Alene Nursery has produced whitebark pine (Pinus albicaulus Engelm.) seedlings for more than 25 years, with 2014 production numbers reaching 214,464 seedlings. Germination remains the largest obstacle in whitebark pine production, due to both the physical and physiological dormancy of the seed. The protocol described in this article outlines the current steps the Coeur d’Alene Nursery uses to break seed dormancy and the growing regime for seedling production. This protocol, which is constantly evolving, serves as a guideline for the production of high-quality plant material for the reforestation and restoration of this important foundation species. This paper was presented at a joint meeting of the Western Forest and Conservation Nursery Association, the Intermountain Container Seedling Growers Association, and the Intertribal Nursery Council (Boise, ID, September 9–11, 2014).
