Description: On two high-elevation sites (~3,000 m) in northeastern Utah, lodgepole pine (Pinus contorta var. latifolia) seeds germinated best (53 percent) on large mineral microsites (5 x 5 m), and percentage survival of germinating seeds was best on microsites covered with forest floor material. Seed predation was severe at both study sites; protecting seeds increased germination three to ten times. On harvested sites dependent on natural regeneration for seedling establishment, some predation control may be necessary to achieve rapid and complete stocking. After harvesting, maintenance of a combination of mineral soil and forest floor is critical for long-term seedling success.

Keywords: lodgepole pine, Pinus contorta var. latifolia, microsites
