Title: Measures of germination and seedling survival for Prosartes lanuginosa, Maianthemum racemosa, and Melampyrum lineareae in the French Broad Watershed, 2009-2011
Abstract: We asked how performance and population dynamics of the temperate forest herb Prosartes lanuginosa differed between recently logged (20-40 years ago) and old (>90 years) logged forests in the Southern Appalachians, USA. We conducted a seed sowing experiment to determine whether germination and establishment differed with stand age. Germination and performance of individual seedlings was monitored over three years across 20 forest stands.
