Description

SnagPRO (Version 1.0) software analyzes log, snag, and tree densities based on peer-reviewed, scientific sampling protocols. It was specifically developed to analyze log, snag, and tree data in support of sampling methods presented in general technical reports (Bate and others, PNW-GTR-746, and PNW-GTR-780) published by the PNW Research Station in 2008. SnagPRO provides example field sheets for data collection as well as a user-friendly, spreadsheet-based process for data input and analyses. SnagPro also provides recommendations for optimizing sample design (sample size and sample stratification) based on pilot surveys. Finally, SnagPRO provides a wide range of statistical analyses and output to meet a variety of analysis needs. All program applications include tutorial files with example uses. The software can be used by any resource disciplines interested in estimating log, snag, or tree characteristics to meet forest research or management objectives.
