Roads are thought to be a proxy for ignition agents such as discarded cigarettes or sparks released from dragging automobile parts, and accessibility linked to human recklessness such as fireworks, barbecues and arson. Recreational sites and trails can also be a major source of human-caused ignitions because hiking and camping often include the building of a campfire that has the potential to spark and grow as a wildfire if left unattended (Pew and Larsen 2001; Reid and Marion 2005).”</div><div class=""><br class=""></div><div class=""><a href="http://www.publish.csiro.au/wf/pdf/WF16108" class="">http://www.publish.csiro.au/wf/pdf/WF16108</a></div><div class=""><br class=""></div><div class="">And this:</div><div class=""><br class=""></div><div class=""><p class="MsoNormal" style="vertical-align: baseline;"><span class="" style="border: 1pt none windowtext; padding: 0in;"><span class="" style="font-family: Roboto, arial, sans-serif; orphans: 2; widows: 2; font-weight: bold;">"ignition</span><span class="" style="font-family: Roboto, arial, sans-serif; orphans: 2; widows: 2; background-color: rgb(255, 255, 255);"> </span><span class="" style="font-family: Roboto, arial, sans-serif; orphans: 2; widows: 2; background-color: rgb(255, 255, 255);">enabled by roads creates a situation where nearly all</span><span class="" style="font-family: Roboto, arial, sans-serif; orphans: 2; widows: 2; background-color: rgb(255, 255, 255);"> </span><span class="" style="font-family: Roboto, arial, sans-serif; orphans: 2; widows: 2; font-weight: bold;">wildfires</span><span class="" style="font-family: Roboto, arial, sans-serif; orphans: 2; widows: 2; background-color: rgb(255, 255, 255);"> </span><span class="" style="orphans: 2; widows: 2; background-color: rgb(255, 255, 255);"><font face="Roboto, arial, sans-serif" class="">originate ….." </font></span></span></p></div><div class=""><a href="http://www.pacificbio.org/publications/wildfire_studies/Roads_And_Wildfires_2007.pdf" class="">http://www.pacificbio.org/publications/wildfire_studies/Roads_And_Wildfires_2007.pdf</a></div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">
