Abstract
Apart from endangering the production of forest biomass, fires may also disturb the ecological balance and disrupt permanent sustainable development. However, fires may have even more tragic consequences, as it was in the case of Kornati in the summer of 2007. Vegetation was investigated and its ignitability and flammability were tested. Ignitability was tested in the laboratory in Makarska using the methodology described by Valette (1990). Field sampling revealed that the shrubs were not burnt and that woody vegetation parts exceeding 5 mm in thickness remained vital and alive. The dry parts of grass vegetation sheltered by stones were also unaffected. Test results showed that the vegetation was extremely flammable. The humidity content of grass vegetation ranged from 10 to 16 % and the ignition time was 2 s. In woody vegetation the ignition time oscillated from 18 to 22 s, with humidity ranging from 13 to 53 %. Vegetation cover ranged from 3,425 kg/ha to 4,948 kg/ha in grass vegetation and from 2,180 kg/ha to 3,425 kg/ha in woody vegetation.
