In 2009-10, to enable monitoring of future growth and mortality of NATL-east's mature hardwoods, Robert Guggenheim, supervised by Tom Walker, measured and mapped all hardwoods with a DBH of 30cm or more. Methods are described at the bottom of this page. All pines in NATL-east are loblollies; on the maps of NATL-east hardwoods. Additional information about NATL-east's pines is available at Maps of NATL's Pines and in the Pines layer of NATL's ArcGIS map.
Maps of hardwoods in NATL-eastSpecies/Diameter Maps A diameter map of hardwoods shows their species, diameter-breast-high in cm, and location. To download a diameter map for any of the 4 tracts on the map at left, click on the tract of interest (outlined in green and labeled in red). H-number Maps "H numbers" provide a unique identifier for each hardwood tree and facilitate access to other data for all hardwoods that are part of the Hardwoods layer of the NATL GIS map. To download a H-number map for a tract, select the appropriate link below. northwest NATL-east northeast NATL-east central NATL-east south NATL-east Excel spreadsheets The spreadsheet GISpines.xls has the same data as the .dbf file of the Hardwoods layer of NATL's ArcGIS map (GIS with hardwoods updated here). This includes a record for each tree, with its H-number, NATL tract and grid square, UTM coordinates, diameter in cm, date of measurement, notes, and changes since 2009. Another spreadsheet, NATLe_Hardwoods.xls, summarizes the hardwood mapping project by tract. |
