THE AREA OF STUDY In the area, that is 4.079 hectare and is located in the boundaries of the of the Gallipoli Peninsula Historical — National Park in Ecebat in Canakkale, a fire broke out and was extinguished in about three days . The area of study is located between the following coordinates: 40° 41° 32°" - 40° 22’ 45” northern parallels, and 26° 12° 57°°-26° 25° 23” eastern meridians as they are shown in figure 1. 674 hectare of the burned area was the destroyed area, and 3.375 hectare of it was the productive forest.

Location of the area of study. 2.1 Vegetation Type The Gallipoli Peninsula is located over an area of 1684.02 km2 and is rich in forest resources. 23% of the total area in the forest is consisted mostly of pine trees together with other species with leaves and groups of bushes. This kind of vegetation is especially susceptible to fire. 2.2 Climate The climatic regime determines the vegetation in a particular region, and hence plays a dominant role in creating areas prone to fire. The study area has the Region of Marmara’s climate that has the peculiarity of transition from the Region of Black Sea’s climate to that of the Region of Mediterranean. In this climate type, it is cold in winter, hot in summer and rainy in spring and autumn. Annual Low Rain 475.8 mm Annual Low Temperature 14.4 C Annual Relative Humidity 80 % Annual Wind Speed 4.5 m/sec The Faster Wind Direction South-South/East 30 m/sec Even though the annual wind speed is about 4.5 m/ sec, it was about 75 km/ sec. on the day the fire broke out. 34 2.3 Topography Topography is an important physiographic factor, which is related to wind behaviour, and hence affects the fire proneness of the area. Fire travels most rapidly up slopes and the least rapidly down slopes. The historical peninsula has an uneven land structure. Its structure is mountainous faulted and is consisted of slopes. 2.4 Distance from roads Forests that are accidental / man-made can be resulted by the movements of humans, animals and vehicles. Thus, forests that are near roads are fire prone. Many roads traverse the study area. This makes people and animals grazing there the cause of fire in the forest. 2.5 Distance from settlements Forests located near settlements can be said to be more fire prone since the people living there can cause an accidental fire. Crowded settlements are located within the forest in the study area, so they can cause forest fires. 3. MATERIALS AND METHODS 3.1 Data The images of Landsat TM in 1992 before the fire and the images of that in 1998 after the fire were used for defining and identifying the burned area and for estimating the vegetation loss. Besides the satellite data, the topographic maps were used in this project. The data collected for this study area were the following: forest type map, vegetation map, elevation, slope, aspect, standard topographic map and climate data (average wind, rainfall data, and temperature). 3.2 Methods Standard topographic maps at a scale of 1:25 000 were digitized and DEM were produced for the study area (figure 2).
