We update and expand the 1992 survey of research findings by Lowell and colleagues, providing an ecological context for the findings, using a more readerfriendly format, and including extensive citations so readers can get indepth information on particular topics. Our intent is that managers will use this report as a desktop reference and field guide. The worksheet can be copied and taken to the field, as a reminder of key indicators to look for and key questions to ask. With a visual assessment process, potential volume and value losses associated with disturbance can be estimated for postdisturbance management planning.
