In 2008, to enable monitoring of future growth and mortality of NATL's mature pines, a project was begun by Robert Guggenheim to measure and map all pines that were believed to have been present when NATL was founded in 1994. Earlier projects and methods of the current work are described at the bottom of this page. On the basis of land use, the maps are in three sets in NATL-west. NATL-east has a single set.

Maps of pines in NATL's restored upland pine
When NATL was established in 1994, none of it had burned in more than 50 years. As a result, there were no young longleaf pines in the more than 15 acres dominated by mature longleaf pines. NATL's planning and management committee (NAAC) designated most of these acres to be restored to a healthy upland pine ecosystem. Restoration started in 1995 in NATL's public area and soon expanded to include similar habitat in NATL's restricted area. As restoration progressed, mature longleafs died and no record was made of their loss or its causes. In some cases the cause seemed clear (blown down, struck by lightning, too much duff burned around base) but in many cases it did not. For example, in September 2004, winds from hurricanes Francis and Jeanne felled only two longleaf pines in the resticted area, but in 2006 during and soon after a severely dry spring, several times that many died. Might this have been from mechanical damage to the roots during wind-induced swaying of the trunks in September 2004?
Diameter Maps A diameter map of pines shows their species, diameter-breast-high in cm, and location. To download a diameter map for any of the ten tracts of restored upland pine, click on the tract of interest (outlined in green and labeled in red) in the map at left. P-number Maps "P numbers" provide a unique identifier for each pine tree and facilitate access to other data for all pines that are part of the Pines layer of the NATL GIS map.

This includes a record for each pine, with its P-number, NATL tract and grid square, UTM coordinates, diameter in cm, date of measurement, notes, and changes since 2008. Another spreadsheet, PineSummary.xls, summarizes the pine mapping project by tract. |
