Opinion 4A Tuesday, September 29, 2020 Other Views Houses must be built to withstand fi re hat the scene has become familiar makes it no less wrenching: A distraught couple searches through the ash, char and melted metal of what was once their home. Only the concrete pad and the occasional fi replace remain. What also is in that tableau are trees. A few are killed and many are scorched, but most are alive and green. The house vaporized because it could not cope with fi re; the forest survived because it could. And paradoxically, it was the house fi re that killed the trees. Those ear- ly-kindled houses STEPHEN then cast fi re to neighbors. What PYNE began as a wild- WRITERS ON THE RANGE land fi re ampli- fi ed into an urban confl agration. It’s the sort of scene JACK COHEN that was common WRITERS ON THE RANGE in the American frontier over a century ago. Watching it burn through Paradise or Berry Creek, California, today is like watching smallpox or polio return. Yet detailed studies, over and over, move the primary problem from the source, where the fi re comes from, to the “sink,” where the fl ames go. A tidal wave of fi re we can’t stop. But the threatening fi re actually moves into and through the town more like a blizzard of sparks: If there are places of vulnerability, embers will fi nd them. That is why the best defense is to harden our houses. Surviving fi res depends on what fi re researchers call the “home ignition zone” (HIZ). Flammable roofs, close vegetation next to wood siding or porches, ground cover that can carry fi re along the surrounding surface — all are chinks that fi re can exploit. Since structures typically occupy a setting with other structures, the vulnerability of each depends on the vul- nerability of its neighbors, and a town itself might be lik- ened to a rambling structure that also needs defensible space. Zoning, greenbelts and codes regulating the relative risk of collective housing won’t halt embers, but they can make protecting hardened structures easier and safer. Call that expanded site the “housing environmental risk zone” (HERZ). Because the reality is we can’t abolish fi re in the countryside and shouldn’t want to. A century of trying has taught us we can’t muster a counterforce to halt the confl agrations that cause most of the damage. Even attempting to eliminate all fi res only disrupts ecological benefi ts and lets fuels build up that create the conditions for even worse fi res. So while the fi re source does matter, the fi re sink matters more. We’ve lived through waves of fi re like this before, twice. The country endured a horrifi c chronicle of con- fl agrations with agricultural settlement through the 19th and early 20th centuries. And it suffered through routine city infernos that burned like their surrounding land- scapes since they were made of the same materials. The last big urban outbreak occurred when San Fran- cisco burned in 1906. The last big rural community that burned during the 1918 fi res occurred outside the town of Cloquet, Min- nesota. It killed 435 people, some while fl eeing in their automobiles. In recent decades the country has recolonized for- merly rural lands with an urban outmigration. Most are exurbs that don’t rely on a rural economy or use fi re in traditional ways. The fi re susceptibility that resulted, however, was identifi ed by the wildland fi re commu- nity as houses crowding into wildlands. More accurately, the scene could just as easily be characterized as bits of cities with peculiar landscaping. Do that, and it is clear what measures must be taken to protect them from fi re. You apply the same strategies and techniques that earlier removed fi re from cityscapes. Meanwhile, the wildland-urban fi re problem has been unnecessarily complicated because it got misdefi ned. It will prove tricky to unwind, because so many com- munities built in the fl ush times will have to be retro- fi tted to accommodate the current conditions. The good news is that HIZ, HERZ and history show us where to concentrate the effort. The bad news is that there isn’t much time to dawdle.

T Letters We should all be praying for unity In reply to Anne Morrison’s “My Voice” (Sept. 12): I am extremely sorry you went through that horrible experience. No woman should have that happen to them, and I cannot in my heart fi nd any excuse for it. These may be your feelings toward our president, but what about the claims toward Vice President Joe Biden? Do you excuse him, or Presi- dent Bill Clinton, or any of the other numerous politicians and other public offi cials who have been accused and condemned of the same things? A great many of us are called racist without cause and accused of many acts just because we believe in the right of liberty and free speech. That is why you have the right to write your letter, as do l. Respecting the opinions of others should also be considered. Will you vote for someone who has been accused of those same things as I read your critique of Oregon’s habitat plan in the Sept. 12 “Our View.” I wonder why you call a mod- erate reduction in timber harvest a “plummet.” If you spend time in the forest, you will know that nothing resembles those banner years for board-feet. I grew up along with the biggest trees. It rained and rained for eight months a year. The forest fl oor was like a sponge that breathed moisture during four months of sunshine. Fires were seldom. Smoke wasn’t a part of our summers. The timber harvest you promote depends on rainfall. Rain depends on halting climate change. You wrote opinions opposing Oregon’s plans for climate stability. You scoff at saving habitat for birds and critters. Well, they keep the earth in balance. Animals and birds consume insects and keep the soil alive. To remove them would be like removing everything from your diet except bread. A forest needs balanced nutrients to grow and thrive. For once, just listen to the scien- tists who have studied our forests for decades. Let’s show respect for their work and preserve habitat before it’s too late.
