 						Estimating Aboveground Net Primary Productivity in Forest-Dominated Ecosystems

Show Summary Details


This chapter focuses on the measurement of aboveground live biomass increment and tissue mortality in forest ecosystems. Standardized approaches for quantifying wood production, tree mortality, and the production of ephemeral tissues (foliage, fruits, etc.) are described in detail, including sampling strategies and precautions. The development of reliable allometric equations relating stem diameter and tree biomass is examined. A variety of special considerations, including losses to herbivory, leaching and volatilization, as well as approaches for scaling and sample adequacy determination are described.

Keywords: biomass increment; tissue mortality; herbivory; allometric equations; tree
