In addition to what Stan mentions, Decaid is an interactive program where
one can set up scenarios of decaying wood in stands, both down and
standing, project over time, and determine what kind of habitat is
available for many species. The scenario habitat suitabilities are based
on the existing literature and the supporting citations are available in
the program. It can be found at:

Hello all --
You may be interested to know that the U.S. Forest Service website at
http://www.fs.fed.us offers the opportunity to search for publications and
even to download them by looking for the publications link on the left hand
side of that web page. Below is an example of a 2004 paper of interest
that
I found using keywords snag, management, wildlife. One can do refined
literature searches of all Forest Service publications covering many years
...
Here is one paper of interest resulting from my search:
Title: DecAID advisor: a tool for managing snags, down wood and wood decay
in PNW forests.
Author: Marcot, Bruce G.; Gunderson, Grant; Mellen, Kim; Ohmann, Janet L.
Date: 2004
Source: Western Forester. July/August: 12-13
Description: Past tools for modeling and setting guidelines for snag and
down wood management have been based on theory, professional judgment,
models of wildlife species use as habitat and empirical data. However,
recent studies reveal that guidelines for amounts of snags and down wood on
national forests of Washington and Oregon may have been lower than the new
field data on use by wildlife. Wildlife studies also show that decayed wood
elements consist of more than just snags and down wood and that decayed
wood
provides habitat and resources for wider array of organisms and beneficial
ecological processes than previously recognized. Thus, there is a need for
a
new approach to describe and advise on appropriate sizes and amounts of
wood
decay elements for forest ecosystem management.
