The manual is a compilation of the study techniques used for the long-term forest ecosystem research project at the Holt Research Forest in Arrowsic, Maine, plus brief evaluations of each method's advantages and drawbacks. It is based on 12 years of work by a team of three university professors, an associate scientist, who has lived on the forest since 1983, a-research assistant, several graduate students, and numerous undergraduate field assistants. We hope this manual will be useful to other researchers planning, or already involved in, other forest ecosystem studies.
