还想回去尝尝四月说的朝鲜蓟心面包呢!山火应该没有烧到镇子上,但是离那边太近,不知道什么时候能消停了。

预期中的第二次雷闪天气没有来。我在黑夜中触角全伸了一夜的元神终于归了位。虽然湾区的两大火区都只contain了10+%左右,但是没有天灾相助,火总是会熄灭的。

过去一个星期天天烟味呛人,天空在橙色与灰色之间随意搭配,清晨我在焦虑中醒来,天尚未全亮,几乎感觉能看到窗外的烟的形状。有几个邻居每天观察空气PM 2.5指数,最高曾经到达600+。大约是政府在林中放了监控摄像头,邻居每天去看几个公共监控摄像头中的景象,已经卫星图片数据,播报给大家。

一个小时多一点的电闪雷鸣,一个星期灭火之后,这是今天整个加州的火情:
https://scdd.ca.gov/wp-content/uploads/ ... t-0800.pdf

所有的山全在着火。加州周围一圈的山接住了雷闪,中谷农业地区看上去没受影响。硅谷在中间山脉夹着的海湾处,所以叫做湾区。硅谷两边夹着的山,东湾与半岛的火灾是十年来最大的火灾。东湾34.7万英亩坡地被烧毁,半岛7.8万山林被烧毁。全县6万人被强制撤离。半岛山林是大片的西岸著名的红木林。硅谷人最喜欢去露营的big basin 公园被烧毁。两个本地报纸mercury news的记者徒步走进big basin 照回来的照片满目疮痍。红木是没有寿命限制的,又抗虫害,如果没有火灾可以一直活下去。

前天国民警卫队来湾区帮助灭火。今年,我习惯了荒诞不经才是正常,听到国家还有部分正常运转居然吃惊了一下。据说有团伙专门去偷撤离家庭的财务,消防队长的车窗被砸,消防员的钱包被偷。

有朋友强制撤离,家里养了无数的鸟类。还好第二天警报解除,得以回家。也有邻居有亲友在其他地区,干脆去亲戚家躲躲,某人替他们把垃圾桶推回去。据说附近了酒店都住满了人。很多朋友都来问候,说有需要可以到家里挤挤,非常感谢。UCSC 校区也在撤离,听说安排了很多Evacuation Shelter,三餐都有保证。

原本以为是看热闹:

地面看确实这样:

湾区是环绕san Francisco bay一圈的地带,所以叫San franciso bay area, 总共九个county,Santa clara county是最大一个,就是硅谷。napa , sonoma ,半岛(San Mateo county),三藩市,东湾(alameda) ,都是湾区。

红木的新树苗都要经过火浴才能破“茧”而出,所以每一次火灾都是红木林的一次新生。自然会恢复的。。。

关于森林大火,我看见了不同的说法。有的生态学家认为像红杉这样的树种在进化的过程中适应了像加州这样的山火频发的地域,但并不表明它们必须要山火才能延续下去。更重要的是,近年来由于气候变暖的影响,山火根本不是小规模的、贴着地面的火,而是持续时间长、大范围的灾难,红杉林根本来不及自我修复。

8.24.2020 Mercury News: Burned Redwood will recover soon
California fires: Burned redwoods at Big Basin, other parks will recover soon, experts say
Studies after other fires in redwood forests found trees turned green in months

By PAUL ROGERS | progers@bayareanewsgroup.com | Bay Area News Group
PUBLISHED: August 24, 2020 at 2:16 p.m. | UPDATED: August 24, 2020 at 9:33 p.m.

The historic fire that roared through the ancient redwoods of Big Basin Redwoods State Park in Santa Cruz County, blackening all 18,000 acres of California’s oldest state park and destroying its historic buildings, has drawn international attention and prompted an outpouring of grief and concern.

But fire scientists who have carefully studied other coastal redwood forests after wildfires have surprisingly good news: Don’t worry. Even though they look terrible now, most of the trees will recover.

Not in 100 years. But much sooner. Amazingly, most of the giant, scorched black trees will begin sprouting green leaves again by this winter, they say, when rains begin. Coast redwoods, the tallest trees on Earth, have the Latin name Sequoia Sempervirens, which means “ever-living Sequoia.” Their breathtaking ability to stand tall in the face of floods, fires and other calamities is how they live to be up to 2,000 years old.

Individual trees at Big Basin today were standing during the Roman Empire. And, the scientists say, they will endure.

A San Jose State University scientist who monitored 667 trees in three areas in the Santa Cruz Mountains after lightning fires in 2008 and 2009 at Bonny Doon, Mount Madonna County Park and Swanton Pacific Ranch found that 88% of the redwoods that burned there lived and were regrowing two years later. By comparison, only 25% of Douglas fir trees survived.

“The redwoods were really resilient. Anything with a diameter bigger than 3 inches basically survived,” said Rachel Lazzeri-Aerts, an instructor in the Department of Environmental Studies at the university.

“Some of those trees looked like little charcoal sticks,” she said. “Within a year they sprouted new growth, new needles. They looked like bright green pipe cleaners. It was really kind of cool.”


Similarly, in the late 1980s, Mark Finney, a graduate student at UC Berkeley, burned 20 plots of redwoods, each about half an acre, in Trione-Annadel State Park in Sonoma County and Humboldt Redwoods State Park in Humboldt County to test their resilience to fire. He burned in spring and fall, and from low to very high intensities, with inmate fire crews standing by.

“We tried our best to kill them and we couldn’t,” he said.

Unlike many other trees, redwoods have cells that lie dormant in their trunks and limbs for centuries, he explained. When the trees burn, the cells sprout new buds. Moreover, their bark is up to a foot thick, and fire-resistant. As long as every part of the cambium, or softer inner layer under the bark, isn’t destroyed, the trees almost always recover from fire, he said. Even if they topple, new redwoods sprout from the same roots.

“These trees are amazing,” Finney said. “Redwoods are an ancient lineage. There are fossils of them from tens of millions of years ago. It’s not the same kind of creature as our other trees. They have lived through a lot.”

Finney, now a research forester with the U.S. Forest Service’s Missoula Fire Science Lab in Montana, looked through photos taken at Big Basin last week by a Bay Area News Group photographer.

“None of this looks that bad to me,” he said. “There’s a lot of scorch in there, but most of these trees are fine. You can see brown foliage on these trees. It doesn’t mean the tree is dead at all. It means the foliage is dead, but the buds underneath the branches and main stem are still alive, and they will probably sprout right back. Most of these trees will do just fine. I know it sounds shocking. If this was a forest in the Sierra Nevada, most of them would be dead.”

Redwood trees burned in the 1991 Oakland Hills fire, he said. Some looked like black telephone poles afterward, but most grew back. A few will be so badly burned in Big Basin at the base that they may topple. But most won’t, he added.

Another researcher who studied four areas in Mendocino County, Big Sur and Santa Cruz after the 2008 lightning fires found the same thing.

“One year later, even large trees where all the foliage was scorched off were covered with a light green fuzz of new foliage,” Ben Ramage, a former ecologist at UC Berkeley, said at the time. “Of trees over 1.5 feet in diameter, maybe only one redwood out of a hundred was killed.”

Climate change will make future fires burn hotter, said Reed Noss, a renowned conservation biologist who wrote “The Redwood Forest: History, Ecology, and Conservation of the Coast Redwoods.”

“These trees are very resilient,” he said. “They can bounce back. But the resilience is being pushed to the limit with this new climate.”

The fire burning now in Santa Cruz and San Mateo counties, called the CZU Lightning Complex Fire, started Aug. 16 during a lightning storm. By Monday night, it had burned 78,684 acres, destroyed 276 structures and killed one person. It was 13% contained.

It has mostly burned redwood forest land. In addition to Big Basin, the fire has made its way through undeveloped parts of Henry Cowell Redwoods, Butano, Portola Redwoods, upper Wilder Ranch and Cascade Ranch at Año Nuevo state parks, in areas with lots of dead brush due to generations of fire suppression. The last time a major fire burned in the Santa Cruz Mountains was 1948, when the Pine Mountain Fire blackened 16,000 acres between Boulder Creek and Bonny Doon.

In 1904, a large fire at Big Basin prompted the New York Times to report that the park “seems doomed to destruction, though hundreds of men are fighting the fires.” But only the eastern third of the park burned. Generations of visitors since have marveled at the 250-foot trees bearing black scars from that fire.

“People are saying on my Facebook and Instagram pages ‘Oh my God, the park is gone,’ ” said Lazzeri-Aerts. “I’m telling them the trees will regrow but the historic buildings and everything in them — the historic pictures, the documents, the exhibits on the walls — can’t be replaced. In the short term, the trees are going to look kind of charcoal-y, but it will all come back.”

我不是专家,刚才搜了一下生态学论文没搜出来。Peter Wohlleben在他的书里多次提到,他应该也是引用的。

我相信红杉林的修复能力,但我关心的是过去几十年来山火的规模越来越大持续时间越来越长,再加上其它的环境破坏,再抗烧的红杉也需要时间来修复。按照人类的time scale,还有时间吗?四月贴的新闻里说:“In the short term, the trees are going to look kind of charcoal-y, but it will all come back.” 树会恢复的,需要十年,五十年,还是一百年?人类还能见到吗?

顺便推荐一下Peter Wohlleben,他的The Hidden Life of Trees: What They Feel, How They Communicate – Discoveries from a Secret World完全改变了我对树和森林的直观印象。在气候问题上,Peter Wohlleben其实算乐观派。 树生活在慢车道上,动物(包括人类)生活在快车道上。人类搞地球,先搞死的就是自己。没关系,树还在,地球会慢慢恢复的 :worthy: 所谓高等生命则不一定。

说得就是这个意思。人类能活得到一百岁的不多,不能因为红杉可以最终自我修复就不考虑人类对它们的破坏。山火是自然的一部分,但越演越烈的趋势是人类造成的。

我们预定的bioluminescence kayaking因为point reyes山火关了两周,现在员工急于挣钱,增加了班次,我们候补上了下周末。乌云也有银边。

是夜晚去看发光的鱼群,还要特意挑没月亮的夜晚,不知道能不能看到水獭. 闪电那晚的白天我们去monterey的 入海口kayak,海獭一家一家的出来晒太阳。

这个团本来包含划艇到Tomales bay 集体露营,因为covid禁止组织集体camping,取消了。除非大家庭包个私家团。

我原先一直觉得象终结者那种科幻片把未来描写得地狱一样太会扯了。唉,看到昨天一整天那深橘黑色的天,原来是我天真了。原本天气预报是90+华氏度,因为太阳已经完全被粉尘遮住,这两天的最高温度都只有60+华氏度。

给其他地方的同学讲解下,上面小情给的录像是昨天的实景,不是做的。北方加州与Oregen的大火形成的大量粉尘升到1000米以上的高空,飘到了湾区,遮天蔽日,白天都没有太阳,就像永远没有白天一样,原本预告酷热的天气,温度比预期低了30华氏度。就跟终结者里描述的已经不适合人类生存的未来一样。

好恐怖。NPR采访一个农场主,他说动物都吓得安静了,鸡不下蛋。
读了篇纽约时报的报道,说气候变化的灾难会多重叠加。2017年加州干旱,死了一亿六千万棵树,所以这次火势广扩散快。浓烟造成居民呼吸系统出问题,去医院,给新冠期间已经重负的医院带来更多负担。被烧的房子将在未来多年被燃烧的塑料释放有害成分进入水系统。
