Estimates were based on precut forest biomass, volume, density and mass of debris at year 1, and wood density changes by year 6 and mass changes by year 7.  Decay constants (4k5) for mass losses were relatively high compared with other studies of wood decomposition. Mass loss occurred largely through wood density decreases and bark fragmentation. CO2-efflux estimates accounted for over 90% of the density loss and for two-thirds of the total debris mass loss. The remaining mass loss of total debris is a source of large, organic matter inputs to the forest floor via solution fluxes and fragmentation. Density loss varied by more than 10-fold among tree species. Density loss rates were 40% higher in logs on the ground versus those off the ground, 100% higher in logs with observable fungi versus those without fungi, and 40% higher in logs that occurred in plots with south and east aspects.</style></abstract><accession-num><style face="normal" font="default" size="100%">LTER.1987-81002</style></accession-num></record></records></xml>
