The ones in Arizona forests often have burn scars every ten years or so. My parents' place in Prescott had several. Two were at least 30 years old in 1960. The pine beetles finally killed them. My brother, who still lives there, was looking at perhaps $2000 to take them down when the power company came by last year and took them out. Cut them up to fireplace size, and someone he knew took them away.<br></div></div><div><br></div><div><div style="font-size:small" class="gmail_default">Ponderosas are lovely trees; it is not hard to see why people want to live among them. But they are definitely a fire hazard, though maybe not as bad as the eucalyptus that burned in the big Oakland fire. My brother lives downwind from a ponderosa forest in mostly juniper and oak. He knows the house is not likely to survive a forest fire, but he won't clear out the trees. It would ruin the view.<br></div><div style="font-size:small" class="gmail_default"><br></div><div style="font-size:small" class="gmail_default">Keith<br></div></div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Aug 5, 2026 at 5:49 PM spike jones via extropy-chat <<a href="mailto:extropy-chat@lists.extropy.org" target="_blank">extropy-chat@lists.extropy.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><div lang="EN-US"><div><p class="MsoNormal"><span style="font-size:11pt;font-family:"Calibri",sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:11pt;font-family:"Calibri",sans-serif"><u></u> <u></u></span></p><div style="border-color:rgb(225,225,225) currentcolor currentcolor;border-style:solid none none;border-width:1pt medium medium;padding:3pt 0in 0in"><p class="MsoNormal"><b><span style="font-size:11pt;font-family:"Calibri",sans-serif">From:</span></b><span style="font-size:11pt;font-family:"Calibri",sans-serif"> John Clark <<a href="mailto:johnkclark@gmail.com" target="_blank">johnkclark@gmail.com</a>> <br><b>.</b></span><span style="font-family:"Arial",sans-serif"><u></u><u></u></span></p></div><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal"><b><span style="font-size:13.5pt;font-family:"Tahoma",sans-serif">>…Spike</span></b><span><b><span style="font-size:13.5pt;font-family:"Arial",sans-serif">,</span></b></span><b><span style="font-size:13.5pt;font-family:"Tahoma",sans-serif"> I'm very glad that neither<span> </span>you <span>n</span>or any member of your family were hurt <span>by the wildfire…<u></u><u></u></span></span></b></p><p class="MsoNormal"><span><b><span style="font-size:13.5pt;font-family:"Tahoma",sans-serif"><u></u> <u></u></span></b></span></p><p class="MsoNormal"><span><b><span style="font-size:13.5pt;font-family:"Tahoma",sans-serif"> Thx John. </span></b></span><u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><blockquote style="border-color:currentcolor currentcolor currentcolor rgb(204,204,204);border-style:none none none solid;border-width:medium medium medium 1pt;padding:0in 0in 0in 6pt;margin-left:4.8pt;margin-right:0in"><div><p class="MsoNormal" style="margin-left:11.55pt"><span><i><span style="font-size:13.5pt;font-family:"Arial",sans-serif">> </span></i></span><i><span style="font-size:13.5pt;font-family:"Georgia",serif">Our recent fire catastrophe in Spokane was human caused, but nature also played a big role: the wind enabled a lone arsonist to destroy hundreds of homes…</span></i><u></u><u></u></p></div></blockquote><p class="MsoNormal"><b><span style="font-size:13.5pt;font-family:"Tahoma",sans-serif">…</span></b><u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal"><span><b><span style="font-size:13.5pt;font-family:"Tahoma",sans-serif">>…But</span></b></span><b><span style="font-size:13.5pt;font-family:"Tahoma",sans-serif"> there is an <span>INVERSE</span> relationship between the strength of <span>the P</span>acific<span> </span>El Niño<span> and Atlantic hurricanes; the stronger the </span>El Niño<span> is the dryer and more fire prone Spokane becomes however thanks to El Niño…John K Clark<u></u><u></u></span></span></b></p><p class="MsoNormal"><span><b><span style="font-size:13.5pt;font-family:"Tahoma",sans-serif"><u></u> <u></u></span></b></span></p><p class="MsoNormal"><span><b><span style="font-size:13.5pt;font-family:"Tahoma",sans-serif"><u></u> <u></u></span></b></span></p><p class="MsoNormal"><span><b><span style="font-size:13.5pt;font-family:"Tahoma",sans-serif">Ja, they had a dry spring this year, but there was another important factor.<u></u><u></u></span></b></span></p><p class="MsoNormal"><span><b><span style="font-size:13.5pt;font-family:"Tahoma",sans-serif"><u></u> <u></u></span></b></span></p><p class="MsoNormal"><span><b><span style="font-size:13.5pt;font-family:"Tahoma",sans-serif">I agree there will always be an ignition source. Out west of town there are trails out thru the woods, where a prole can backpack and camp anywhere he wants. Campfires can get away from them. Of course there are firebugs, as was the case this time.

These are controversial, since they are known fire hazards. They are native to this area: it was a ponderosa pine forest before developers built the neighborhood in the late 1980s. They thinned the forest, took out the biggest (most dangerous) of the trees, but that species grows a foot to a 1.5 ft per year. It has been 37 years since the area was built up. The trees had nearly ideal growing conditions, since they had been thinned (fewer competing trees) and had plenty of water from being in irrigated lawns. <u></u><u></u></span></b></span></p><p class="MsoNormal"><span><b><span style="font-size:13.5pt;font-family:"Tahoma",sans-serif"><u></u> <u></u></span></b></span></p><p class="MsoNormal"><span><b><span style="font-size:13.5pt;font-family:"Tahoma",sans-serif">I mentioned the trees were controversial. The environmentalists argued that the trees were far less susceptible to structural failure and fire because homeowners took out any which were infested by pine beetles and the lawn trees had plenty of water. However… even with those advantages… those trees were prone to breaking off without warning.<u></u><u></u></span></b></span></p><p class="MsoNormal"><span><b><span style="font-size:13.5pt;font-family:"Tahoma",sans-serif"><u></u> <u></u></span></b></span></p><p class="MsoNormal"><span><b><span style="font-size:13.5pt;font-family:"Tahoma",sans-serif">I took the photo below about one minute after we began evacuation. Note the right side of the photo, there are four trees and one stump about the height a tall man can reach. That tree broke off without warning about two months ago. The tree fell across the road.

About 4 yrs ago, I convinced him to remove the remaining two because of the fire hazard, however there were still pleeeenty of those trees in the neighborhood, which had grown very tall.

Less than one minute after I took this photo, an ash glob about the size of a ping pong ball fell on my windshield. It burned a notch in my wiper.
