摘要

genetically adapted to specific sites can be significant in planning plant restoration work; the ability to evaluate genetic composition and diversity when choosing seed or plant materials from various sites can be an important tool. In restoration practice, there has not been agree?ment on how common population-level or local genetic adaptation may be and the significance it may have for survival and persistence. Further, for small populations of imperiled species, restoration planning has been con?cerned with genetic fitness of remaining populations and possible consequences of genetic drift and inbreeding and outbreeding depression. Moreover, there has been confu?sion in the land management community about whether seed or other material from distant sites is appropriate for use. How then to evaluate the relative merits and risks of matching material from the exact site, the next nearest site, the most similar habitat profile (which may not be the nearest site), or a mixture of material from many sites? Finally, climate change may affect the probability of per?sistence of restored populations and plant communities. The emerging concept of assisted migration and its effect on the survival of restored populations will require evalu
