Faddan More Psalter used as a liner to stiffen the cover somewhat. Low oxygen levels in the bog provide unusual preservation conditions, and bogs were often used by Irish monks as hiding places for valuables in the face of Viking raids. In addition to low oxygen levels, sphagnum moss, of which the peat bog is composed, produces an antibiotic substance called sphagnan that binds with proteins on the surface of microorganisms, immobilising them. Its highly reactive carbonyl groups can alter chemicals and nutrients that would otherwise decompose organic matter. And above all the sphagnum moss causes organic material to undergo chemical changes itself
Fuel model their ability to support Wild-land fire and the degree to which such a fire would consume the fuel lying within the bed. Regionally developed by teams of experts, these models were “compiled from scientific literature, fuels photo series, fuels data sets, and expert opinion.” In addition to the standard dead and live components, the FCCS scheme reports assigned and calculated fuel characteristics for each existing fuel bed stratum including the canopy, shrubs, non-woody, woody, litter-lichen-moss, and duff,” allowing a more comprehensive analysis of material within a fuel bed. Furthermore, “the system classifies each fuel bed by calculating fire potentials that
