Abstract

The AA. established an experiment to determine the effects of a low severity burn on organic and total mass of soils, the position of the water table and vegetation cover. They recorded soil losses directly after the fire, after the first rain and after 4 years. They also compared soil surface temperatures over summer between burned and unburned moorland. The topographic wetness index was strongly related to soil and organic matter loss, while fire severity, slope and vegetation cover were less predictive. Burning increased dissolved organic material in streams, the depth of the water table, and, soil temperatures. The continuing soil loss on slopes 18 years after fire contrasts with faster recovery on the shelves and in the basins, reflecting a strong topographic component in variation
