Ignition Risk Map
Every wildfire requires an ignition source that can be naturally occurring or human-caused. Although a potential ignition source can reside anywhere, areas where ignition sources regularly exist or are more common have a higher potential for wildfire occurrence. The Douglas County CWPP Core Team has determined that high lightning density regions and areas adjacent to railroads, campgrounds, major roads, and hiking trails have the highest potential ignition risk. Some ignition sources tend to spark more fires than others. Because of this, a relative weighting was given to each major potential ignition source. High lightning density regions and areas adjacent to railroads and campgrounds were given the highest weight, areas adjacent to major roads were given the second highest weight, and areas adjacent to hiking trails were given the third-highest weight. Areas, where no apparent major ignition source existed, were given the lowest weight.
