Estimates of dead and down woody material (DWM) biomass are important for nutrient cycling, wildlife habitat assessment, fire effects climate change science. Most methods used to sample initially assess volume then estimates wood density convert biomass. To initial decomposition rate, this study examined in situ lodgepole pine logs at the Tenderfoot Creek Experimental Forest (TCEF), central Mon...
