TAILIEUCHUNG - Fire development from a point source in surface fuels of a mature Anatolian black pine stand

A total of 28 line and 24 point-source fires were ignited under varying weather and fuel loading conditions in Anatolian black pine (Pinus nigra subsp. nigra var. caramanica (Loudon) Rehder) stands. Relationships between the rate of fire spread and fuel and weather conditions were determined with correlation and regression analyses. | Turk J Agric For 31 (2007) 263-273 © TÜB‹TAK Fire Development from a Point Source in Surface Fuels of a Mature Anatolian Black Pine Stand Ömer KÜÇÜK1,*, Ertu¤rul B‹LG‹L‹2, ‹smail BAYSAL3 1 Kastamonu University, Faculty of Forestry, 37200 Kastamonu - TURKEY 2 Karadeniz Technical University, Faculty of Forestry, 61080 Trabzon - TURKEY 3 Duzce University, Faculty of Forestry, 81320 Düzce - TURKEY Received: Abstract: A total of 28 line and 24 point-source fires were ignited under varying weather and fuel loading conditions in Anatolian black pine (Pinus nigra subsp. nigra var. caramanica (Loudon) Rehder) stands. Relationships between the rate of fire spread and fuel and weather conditions were determined with correlation and regression analyses. The rate of fire spread ranged from to m min–1 in line fires. In the ignition, transition, and steady state phases of point-source fires, the rate of fire –1 –1 –1 spread ranged from to m min , from to m min , and from to m min , respectively. Surface fuel –2 –2 loading ranged from to kg m for line fire and from to kg m for point-source fire. The results showed that the rate of fire spread was closely related to wind speed and fuel moisture content for line and point-source fires. The linear prediction for wind conditions estimates that equilibrium spread rates may be achieved within 25 min after the ignition of pointsource fires.
