Dept. of Agriculture, Forest Service, Northern Research Station, 2008 OCLC Number: (OCoLC)244637028 Subject: Wood -- Deterioration -- Measurement. Excerpt: . . . state of FWD by varying the size of the pulse from 5, 10, and 20 times the size of the regular FWD pool. We also varied the asymptotic density of the pulse of FWD from a relative density of 0. 1 to 0. 4 as well as explored the effect of the decomposition rate of FWD. We then noted the difference between the minimum and the average relative density because this indicated the uncertainty that might be introduced by not noting the decay state of FWD. Biomass to Carbon Conversion Factors We reviewed the literature to nd estimates of the carbon concentration of dead wood in various states of decomposition. Given the paucity of data, we averaged across all species within CWD decay classes to derive a mean estimate. For FWD we averaged across all species for undecayed and decayed wood. We used all available data to derive a standard error of carbon concentration, weighting these estimates by the sample sizes reported in the publications. 11 This item ships from La Vergne,TN., RareBooksClub<
