Verification of Germplasm source and status by seed certifying agencies as native plants are collected and cultivated

摘要：

Long‐term success in restoring native species to a specific site or geographic area after natural or human‐caused ecosystem disturbances is most likely when using adapted plant materials from the same site or nearby sites or areas with similar physical and biological environments.For some broadly adapted species characterized by copious seed production, wildland collection can supply a significant seed volume for direct plantings.For most species, however, accessions consisting of limited quantities of seed obtained from defined wildland stands must be increased in fields or nurseries.Unfortunately, accurate documentation for collection site and/or cultivated production has often been unavailable to those seeking site‐ appropriate native plant materials.
