Hybridization in naturally regenerated shortleaf pine near artificially regenerated stands of loblolly pine

Factors leading to introgression in loblolly pine and shortleaf pine may include the distance between stands, or the common condition in which both species are naturally found together in stands in the upper west Gulf region. In the present study we used microsatellites to measure levels of hybridization and introgression in naturally regenerating shortleaf pine stands in the Caney Creek Wilderness Area located on the Ouachita National Forest in west-central Arkansas. This area is allopatric by about 40 kilometers relative to loblolly pine. However, extensive plantations of loblolly pine have been established in this area over the past four decades on private lands managed intensively for timber and fiber productivity in support of local forest industry.
