The percentage figures indicate the proportional size of the burn (inside and outside the Reserve) with respect to the size of the Reserve, not the actual percentage of the Reserve burnt. .. Mapping accuracy We manually digitised 34 out of 75 polygons from hand-drawn paper maps. The majority were from a single map showing fires in 1984, 1989, 1990 and 1991. The fire polygons were digitised to an accuracy of about 520 metres (estimated by comparing the raster contours with vector contours). However, it is likely that the boundaries of the fires were drawn with much less accuracy on the original map. It is not known who drew the boundaries. In some cases the boundaries were probably hand drawn on the base map, using sketch maps made on original fire reports. Others may have been drawn from memory of the burns, field observations or some other interim mapping. Accuracy is likely to vary from +/- 50 metres in the vicinity of hills to +/-200 metres in more open country.
