Field Guides:
The current set of nationally consistent core field procedures used by all FIA units can be found at
http://fia.fs.fed.us/library/ -> Library (upper left hand side) -> Field Guides, Methods and Procedures.
The current version is 6.0 (although the first paragraph mentions 5.1, right below it is the current
version); links to earlier versions of the field guide are lower down on the webpage. The regional field
guide can be found on each of regional websites. The IW-FIA field guide is at

http://www.fs.fed.us/rm/ogden/data-collection/field-manuals.shtml
Coarse Woody Debris:
This will be a P2 core optional variable in version 6 of the field guide.
The CWD is part of the Down Woody Materials protocols which are in section 10.
The estimation procedures for the CWD will be based on the P3 estimation procedures, which can be
found at http://www.nrs.fs.fed.us/pubs/3615

Analysis: Each region has an Analysis group of which analyzes FIA data. One set of products the
Analysis Group produces are the state reports. The IW-FIA state reports can be accessed at:
http://www.fs.fed.us/rm/ogden/publications/index.shtml. Besides the analysis of basic forest attributes
these state reports can contain topics that are specific to that state.
Techniques: Each region has a Techniques group which conducts Inventory and Monitoring Research and
Development. The IW-FIA Techniques webpage is:
