What's wrong with California?! >:T

[Norrath]

Forest fires do not happen out of the blue whenever the brush has "built up enough". A fire CAN clear out the brush before it becomes so flammable that it would burn the durable trees. That doesn't mean it will happen.

Forests do burn down occasionally. Human intervention might have caused a few more of these than would normally occur, but it has also prevented others.

I'm not just saying this as personal ranting; this is a distinctly Western American issue and it's been followed for decades. In 2001 it was federally mandated to start clearing brush in California (which was later canceled). There are documented cause-and-effect relationships occurring here.

Anyway, I did a quick Google search, which came up with an article a lot more insightful than my own writing. Follow the link to read the whole thing.

Why have wildfires--a threat that once seemed to have disappeared--returned with such fury? To find out, VT interviewed Stephen J. Pyne, author of the new book Tending Fire: Coping with America's Wildland Fires. A professor in the School of Life Sciences at Arizona State University in Tempe, Pyne is no ivory tower intellectual: He spent 15 years as a fire fighter at the Grand Canyon and at Yellowstone and Rocky Mountain National Parks. Q: You write that fire had once "receded from everyday life" but is now "more virulent than ever." Why? What's going on? A: We've made public lands--supposedly protected places--habitats for fire because of the way we manage them. In our determination to keep them from burning, we've allowed the very things that catch fire--pine needles, twigs, brush--to accumulate. So when lightning strikes or a campfire gets out of control, fire spreads more quickly than it otherwise might. At the same time, we've begun building housing developments next to woodlands. This complicates matters. We know how to fight fires in woodlands. We know how to fight fires in towns. But these are two different challenges. So when a wildfire in the woods spreads to the suburbs, fire fighters who are trained to work in forests don't necessarily know how to respond. So a fire can roar through one of those housing developments, causing devastation. Q: Have we always viewed fire this way--with these results? A: No. Years ago, we used fire routinely in farming. We understood fire better then, so we weren't as terrified by it. We knew it could be used responsibly. Native Americans also once used fire regularly. They burned their fields, which helped limit the accumulation of brush and branches that fuel wildfires. But Native Americans were driven out. Then settlers in the 1870s and 1880s overgrazed the lands, stripping them of the grasses that tend to burn slowly, and replacing them--again--with materials that burn quickly. By the time protected lands were created, our impulse was to suppress all fires that would naturally occur otherwise. That meant pine needles, twigs, etc., were allowed to build up. Insects, with all the damage they do, were allowed to thrive. In times of drought mid high wind, these "protected" forests become tinderboxes. So when a fire starts, it burns more intensely and spreads more rapidly. Q: You're suggesting that some amount of fire is good. A: It is. Fire functions ecologically in a way that nothing else does. Fire performs biological work that only it can do. It sets into motion a natural recycling of plants and animals. Old trees and bushes are cleared away, so the wind and sun can reach the soil. New species can replenish an area. We almost never think of the good things fire does; we have been conditioned to think only of the damage. We think that fire destroys a log, for instance, which it does. But by destroying the log, it releases everything in the log for other important biological purposes. When a log is turned to ash, phosphorous, calcium and magnesium are released. These chemicals are put into circulation again--in the air, soil or water. Different environmental conditions favor different species of plants. Some plants need lots of light; others don't. Some, such as fireweed, do well in burned-over areas, while others go to seed, waiting for new conditions in which they will do well. The best ecological system is one in which there is continual change, and new species come and go. Periodic fires help make that possible. Q: So fire can be a good thing. But what's the worst that can happen if we continue in our present course of trying to suppress it? A: You can't suppress fire. Fire will come--through lightning, if nothing else--and when it does, it will spread more rapidly and burn even more intensely in areas that no fire has claimed recently. As a result, it will do more damage than a "normal" fire would have done. You're destroying the same wilderness you've set out to protect. Also, unless the brush and pine needles I keep talking about are burned off regularly or otherwise removed, they form a "pavement" of pine needles and twigs that covers up flowers and grasses, which is terrible for the soil beneath. When pine needles break down, they change the chemical composition of the soil, making it more acidic. Most flowers and grasses need soil that is more alkaline, so they won't grow where pine needles build up.

What's wrong with California?! >:T

I'm not in it, that's what's wrong with it!!! Seriously, I hate on Cali cause I'm jealous, and that's the God's honest truth.

But when stuff happens to Cali and Florida, I just can't feel that bad cause it's a paradise there. And bad stuff just has to happen now and then. I'm in crappy Memphis. Nothing happens here. Nothing bad...nothing good. Sigh.

Cider you did a fine job the first time writing...that article is good too. I'm just saying, it's hard to know what good and bad will happen when people try to adminstrate a country. I think people that make these rules and decisions are honestly trying to do the right thing by people, and sometimes collateral damage happens.

It is. Fire functions ecologically in a way that nothing else does. Fire performs biological work that only it can do. It sets into motion a natural recycling of plants and animals. Old trees and bushes are cleared away, so the wind and sun can reach the soil. New species can replenish an area.

I totally agree. Everything in nature has a purpose. By inhabiting this place we alter it for our needs. Sometimes we do things that appear to be good for us, and nature has a funny way of getting its way in spades. I find that in itself a wonderous thing...on a purely academic level. When it actually happens to me, I fully expect to change my mind completely.

That's something I think we fundamentally agree on.

I remember around where I lived they would occasionally set off controlled fires to clear the brush. I wonder if they stopped that for some reason
