Description: The purpose of green barriers, also known as green fuelbreaks, is to reduce the spread and intensity of fire, mainly by stopping it from spreading to the treetops, which facilitates fire control and suppression. A major difficulty in implementing green barriers is to identify suitable species for forming these structures. The aim of this study was to assess the flammability of some tree and shrub species used in urban forestry and along highways in Curitiba for use in green barriers in the rural-urban interface of cities in southern Brazil. To this end, fire behavior and flammability tests (epiradiator trials) were performed in the Forest Fire Laboratory at the Universidad Federal de Paraná on the following species: Magnolia grandiflora L., Michelia champaca L., Jasminum mesnyi Hance, Casearia sylvestris Sw. and Viburnum odoratissimum Ker Gawl. Test results showed that the species J. mesnyi is extremely flammable (FV = 5), M. grandiflora and C. sylvestris are highly flammable (FV = 4), and the species V. odoratissimum and M. champaca are moderately flammable (FV = 3) and low flammability, respectively.

Keywords: epiradiator, flammability, fire prevention
