摘要 | Fuel characteristics, fire behaviour and temperature were studied in relation to grazing, dominant grass type and wind direction in West African savannawoodland by lighting 32 prescribed early fires. Grazing significantly reduced the vegetation height, total fuel load, and dead and live fuel fractions whereas plots dominated by perennial grasses had higher values for vegetation height, total fuel load and the quantity of live fuel load. Although fire intensity remained insensitive (P>0.05) to any of these factors, fuel consumption was significantly (P =0.021) reduced by grazing, rate of spread was faster in head fire (P =0.012), and flame length was shorter in head fire than back fire (P =0.044). The average maximum temperature was higher (P<0.05) on non-grazed plots, on plots dominated by annual grasses, on plots subjected to head fire, and at the soil surface. Lethal temperature residence time showed a nearly similar trend to fire |
