Restoration of many forest ecosystems will require replanting of native species. Choosing the proper seed source is essential to ensure long-term success of restoration plantings, especially if local seed sources are unavailable or genetically degraded. A successful restoration requires seed sources that are adapted to the climate and site, and are genetically diverse to allow subsequent reproduction and adaptation.
