 Motivation and Purpose
In recent years down coarse woody debris (CWD, aka down coarse woody material
(CWM), down dead wood (DDW)) has become a topic of some note in the management
of New England forests and beyond. It enters into the management equation in
myriad ways: logging debris, seedbeds, carbon pool, wildlife habitat, fuel,
etc. Unfortunately, we are still relatively uninformed and unsure just how
important CWD is, and how much is "enough" in a healthy forest. More basic is
the question of how best to estimate amounts of CWD, as part of a forest
inventory to make informed decisions for management. While we still may not be
able to answer all of the questions on the subject, recent research has made
some advances in our knowledge.
The purpose of this one-day workshop is to cover the basics of what you need to
know about the CWD resource in New England forests based on research
accomplished to date at the Northeastern Research Station (USDA Forest
Service), the University of New Hampshire and the New Hampshire Division of
Forests and Lands. The workshop will begin with morning presentations covering
the basics of defining the CWD resource and its importance (i.e., why we should
be concerned with it-why not just burn it!) on up through a look at
"how much is enough" and methods for sampling CWD in the field. The
afternoon session will adjourn to the field where we will measure a number of
plots in crews using two different techniques. Then we will return to the
"office" to analyze our results and wrap it up. The goal is for participants to
take home knowledge of the importance of the resource as well as some tools for
quantification. Computer programs available for analyzing simple CWD
inventories will be provided and available to take home.
