“…21 These two undertakings were responsible for a rapid expansion in the understanding of fynbos ecology, and the role of fire. New understanding was gained regarding the ecological effects of fire, 22,23 of how fire protection led to senescence and poor regeneration after long fire-free intervals, 24,25 and of how to define acceptable, as well as unacceptable, seasons for burning. [26][27][28] On the termination of the Fynbos Biome Project 29 in 1990, it was possible to provide fairly detailed prescriptions regarding the management of fynbos by means of prescribed burning.…”

“…Forest fires are caused by humans, lightning, and other natural causes, with man-made fires accounting for the vast majority, especially in populated regions [3][4][5]. Heilongjiang province, in Northeast China, endures severe forest fires, with the area burned in the province being among the highest of provinces in China [6], according to historical data, since 2005, Heilongjiang province has experienced an average of 69.2 forest fires per year, with an average burned area of 1045.24 ha.…”

Abstract:Cigarette butts are an important human firebrand and account for a significant amount of man-made fires. To better address forest fires caused by cigarette butts, the influencing factors governing the ignition probability of cigarette butts can be used to establish a prediction model. This study obtains the influencing factors of the ignition probability of cigarette butts in order to establish a prediction model by constructing fuel beds composed of Mongolian oak leaves with varied fuel moisture content and packing ratios. A total of 2520 ignition experiments were then conducted by dropping cigarette butts on the fuel beds to test the burning probability of the fuels under varied wind speeds. Moisture content, wind speed, and their interaction significantly influenced ignition probability. In the absence of wind, the ignition probability is zero. The maximum moisture content of Mongolian oak leaves that could be ignited by cigarette butts was 15%. A logistic model and self-built model for predicting the ignition probability were established using these results; the mean absolute error values for the two models were 2.71% and 1.13%, respectively, and the prediction error of the self-built model was lower than that of the logistic model. This is important research to mitigate the threat of forest fires due to cigarette butts given the frequent occurrence of these events.

“…The present management practice of slashing and burning H. sericea is not conducive to the maintenance of good catchment conditions and results in increased soil erosion rates. Van Wilgen (1981), Kruger and Bigalke (1984) and all indicate that for western Cape fynbos communities plant cover should reach 40 % within the first year after the fire. The rate of recovery is probably related to moisture regimes and considerable variation could therefore be expected.…”

“…It has been suggested that animals such as termites, because they live in mounds, are protected against fire (Gandar, 1982;Bigalke and Willan, 1984;Kruger and Bigalke, 1984;Tainton and Mentis, 1984;Frost, 1984). Fire intensity is more likely to affect soildwelling arthropods, which are normally not very mobile, to a larger degree than mobile organisms.…”

Alien Control: Can We Afford to Slash and Burn Hakea in Fynbos Ecosystems?

SYNOPSISHakea sericea, an alien invader in fynbos, can be controlled successfully by cutting and then burning after seedlings emerge. The increase in fire intensity ascribed to burning the dry slashed material was measured. The effect of the increased fire intensity on soils, soil erosion, vegetation and termites were measured. Results show that the present management technique for the control of H. sericea (especially where it occurs in dense stands) has a negative effect on the ecosystem. It is also incompatible with overall management objectives of maintaining both diversity and ecological processes. Alternative techniques for controlling dense infestations should be evaluated.
