| Site Name: | Duke Forest Loblolly Pine |
| Description: | The Duke Forest Loblolly Pine tower is located within the Blackwood Division of Duke Forest near Durham, NC. Upwind from the tower, also residing in the loblolly pine forest, is the free atmosphere carbon enrichment program (FACE) facility. The surrounding stand is a uniform-age loblolly pine forest with a diverse understory of more than 26 species. One of three towers in the Duke Forest, the Loblolly Pine tower represents a later stage of a post-agricultural succession characteristic of the southeastern United States. The forest was established in 1983, when the area was clear cut and burned followed by the uniform seeding of loblolly pine. No known management practices have occurred within the footprint of the tower following initial establishment, yielding a diverse understory composition below a nearly homogeneous overstory. Since measurements began at the Loblolly Pine site, natural disturbances have been an annual occurrence. A drought began during the late growing season of 2001. The severity increased until the drought ended in October of 2002. In 2005, another late season drought occurred, but was confined to a few months. The growing season precipitation was lower than average during the years of drought conditions. In contrast, annual precipitation was higher than average during the 1999, 2000, and 2003 growing seasons. A severe ice storm that occurred in December of 2002, caused widespread damage. One-third of loblolly pines surrounding the tower were damaged with a 12% leaf area reduction and greater than 200 gC/m2 litterfall.
