Preserving park resources and values unimpaired is the core responsibility of National Park Service (NPS) managers. Included in this endeavor is the NPS directive to strive to protect the full range of genetic types (genotypes) of native plant and animal populations found within the parks. NPS Management Policies (2001) specifically have identified that the native plant materials used in restorations will be taken from populations that are as closely related genetically and ecologically as possible to park populations, preferably from similar habitats in adjacent local areas. Although long-standing partnerships with the Natural Resource Conservation Service (NRCS) and associated Plant Materials Centers have proven highly beneficial in the collection and increasing of locally adapted seed materials for use in park restoration activities, availability of adequate quantities of seed materials that meet NPS policy guidelines remains extremely challenging. In addition, use of non-local cultivars and the increasing potential for introduction of genetically modified organisms further threaten the NPS ability to preserve native germplasms. This presentation will focus on discussions of the NPS policy directives associated with restoration of native plant materials, the challenges associated with preserving native germplasms, information gaps, and potential opportunities for increasing partnerships, including working more closely with park neighbors to enhance availability of native plant materials for use at the local level.
