Using local seeds in prairie restoration -- data support the paradigm

Abstract:

Choice among local, non-local, and cultivar seeds for restoring native ecosystems is
not purely an academic question-it also has practical consequences. In this article we
summarize a series of genetic and competition studies of big bluestem (Andropogon
gerardii Vitman. [Poaceae]), Indian grass (Sorghastrum nutans (L.) Nash. [Poaceae]), and
purple prairie clover (Dalea purpurea Vent. [Fabaceae]) from remnant and restored Illinois
(local) prairies, non-local remnant prairies, and 6 grass cultivars.We found genetic
differences between local and non-local seed sources, that large populations do not
necessarily have higher genetic diversity relative to small populations, and differences
in plant performance could be related to seed source.Although obtaining large quantities
of non-local and cultivar grass seeds may be affordable, available, and desirable
given the amount of seeds required for prairie restoration, our research indicates
genetic and plant performance differences between local and non-local seed sources
in all 3 species. Such differences can affect both the short- and long-term success of
restoration activities.
