Flat Laurel Gap Bog, Pisgah Ridge, North Carolina: Late Holocene Development of a

Flat Laurel Gap Bog of Pisgah Ridge in the Balsam Mountains of North Carolina is a high-elevation (1500 m) heath bald and Appalachian bog. The bog sediments furnish a paleoecologic record showing vegetation change over the last 3340 years. The paleoecologic record demonstrates with chronologic control the antiquity of at least some of the heath balds in the Southern Appalachians. Ericaceae plants have dominated the vegetation in the bog for at least the last 3000 years. Circumboreal and boreal heaths that also persisted at Flat Laurel Gap Bog through the late Holocene included Chamaedaphne calyculata and Andromeda sp.
