image - logo for NED softwareNED-2 is the successor to NED-1 and is available for download.

A full online help system is installed with NED-2 and is incorporated with the software. In addition, material contained in the help system is available in two publications, a printed NED-2 user's manual with step-by-step instructions on how to use the software and a separate NED-2 reference guide (available in PDF format only) with detailed explanations of the models, equations, and rules that underlie the software.

Paper tally sheets are available for NED-2, at the bottom of this page under Documents and Downloads. On some of the tally sheet pages, not all NED-2 variables are shown due to space limitations. Download the Excel version of the tally sheets if you would like to substitute variables or make other modifications. A companion PDF version is available that will handle most inventory situations.
