    Successful reforestation requires that planted or naturally regenerated seedlings are well suited to a site. Genetic studies of forest trees provide ample evidence of large differences among seed sources in adaptive traits--traits such as the timing of growth initiation and cessation, cold and drought hardiness, and growth rates. Much of this variation is related to the temperature and moisture regimes of the seed sources. In general, seed sources from near a planting site survive and grow well, whereas distant seed sources are often maladapted.
