Portlethen Moss millennia of evaporation, further intensifying the soil acidity, fueled by organic matter decaying, with little drainage outlet. A layer of sphagnum moss would have developed at the benthic level of the bog, and additional sphagnum layers floated in mats atop the bog. At an intermediate level of evolution, thick peat layers formed from decay and carbonisation of the rotting sphagnum. Generations of carex and juncus flourished, leading to further decay of these materials and eventual heightening of the organic mass. Finally, secondary vegetation took root in the spongy sphagnum mats adding greater biomass to the bog.In some cases the heavy
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
