# Fine wood decay studies across western USA, North Carolina, USA, Mexico and Russia, 1989 to 2015 ## Dataset - **Database Code:** TD021 - **Title:** Fine wood decay studies across western USA, North Carolina, USA, Mexico and Russia, 1989 to 2015 - **Abstract:** This study was established to examine the loss of mass and changes in nutrient content of fine woody debris in various ecosystems. Also examined was the effect of piece size, position (aboveground, belowground, or suspended), and species on loss of mass over time. - **Keywords:** decomposition; nutrient cycling; detritus; inorganic nutrients; nutrients; wood; woody debris; organic matter; fine woody debris; inorganic nutrients; organic matter - **Temporal coverage:** 1985-10-15 to 2015-10-29 - **Principal Investigator:** Mark E.
