PTAEDA4.0: Simulation of Individual Tree Growth, Stand Development and Economic Evaluation in Loblolly Pine Plantations.

PTAEDA4.0 is a growth and yield model for professional foresters that provides yield estimates in tons to various merchantability limits for pulpwood, chip-and-saw, and sawtimber product categories. Significant enhancements over the base model include the capability to input directly the diameter distribution of an existing stand along with the percent of trees in each diameter class that are defective. This capability is essential for accurate segregation of volumes by product class and for accurate projections of future volumes. In addition, a graphical thinning capability has been added so that selection of trees to be thinned is completely flexible. Linked to the Stand Visualization System (SVS) developed by the Forest Service, version 4.0 provides a year-by-year visualization of the stand development process.

Developed in conjunction with Paul Teter, Forester, LLC version 4.0 can be a valuable tool for  helping professional foresters manage loblolly pine plantations in the South.
