The researchers investigated methods for restoration of six forest herbaceous perennial species with potential for increasing nutrient capture and storage in degraded remnant forest systems in Iowa. They conducted common garden (greenhouse) and field planting experiments using local and non-local propagules.
How successful are transplanted individuals of these species in terms of survival? Are there differences in vegetative and reproductive growth among source populations of these plants that could influence their long-term performance?
Generally, bare-root plants from local (97 percent) and non-local (100 percent) populations had very high survival rates in the common garden study. For the field study, average survival rates were 83 percent (with one exception as noted) for local seedlings and 81 percent for non-local plants.
