Among several silvicultural measures of forest fires prevention, fuelbreaks stands out. These structures are used to reduce and/or prevent fire spread. They consist of plantations with lower flammability species than the main species. The aim of this study was to evaluate the flammability of Psidium cattleianum Sabine., Ligustrum lucidum W. T. Aiton., Schinus terebinthifolius Raddi. and Bougainvillea glabra Choisy, for potential use in fuelbreaks. In this research Pinus taeda L. was used as control. Samples consisted of 1 g of fine material (< 0.7 cm of diameter) newly collected. Samples burning were performed in epiradiator, under temperature between 250 °C and 350 °C. It was carried out 50 replications for each species. It was analyzed ignition... |

Spatial modeling of forest fire risk has the aim to determine areas most susceptible to fire based on variables that represent facility of ignition and propagation. This work developed a forest fire risk map for the Municipality of Inhambupe, Bahia State, Brazil, by elaborating thematic maps of the following variables: road system, population density, land occupation and use, watershed network, slope and aspect. These were evaluated by the analytic hierarchy process and integrated with map algebra. Based on the developed model, 75.46% of the studied area was classified as “high”, “very high” and “extreme high” fire risk. When comparing the forest fire risk map with historical data of burned areas, 95% of the fires were in these areas. |
