Jack Pine: Guidance for Seed Transfer Within the Eastern United States

Jack pine grows in boreal forests across the North American continent. Genetic diversity of this species is high and clinal, but populations exhibit genetic structure that is higher than other conifers with similar life-history traits. Cones are serotinous across most of its range but may be non-serotinous along the southern edge in the Lake States. The serotinous habit may limit seed dispersal and is likely the primary contributor to the genetic structure apparent in studies of mitochondrial DNA. Jack pine originating from southern sources tend to outgrow local or northern sources. Jack pine is likely to persist with climate change in its current range because of its tolerance to xeric conditions. Assisted migration should be well-tolerated by planting seed originating from 100 mi (160 km) to the south, but managers should avoid transferring seed more than 100 miles from origin and be aware of potential pests including jack pine budworm and eastern gall rust.
