So there was drunk person drive car in to young tree in traffic circle and killed it and Seattle took it all out and now people keep drive they cars right over whole traffic circle so guardian Librarian and Pixie make this urban scare crow Pixie really sad about little tree friend but also all Pixies sleeping flowers getting squished maybe will need all new flowers this spring

An ancient Alder came down in the rains last night.

It's friends stand over it and mourn.

But it was tired, and it was it's time. In death, as in life, it will provide wildlife habitat, it will just be home to a different set of citizens.

Though, some of it's original tenants will remain. Old friends, to help the Alder in its transition.

Have you ever thought about how weird the tradition of Christmas trees are like we violently saw down a living thing and then once it's displayed in our homes we hang things on it's limbs that we find aesthetically pleasing and watch it slowly die in a corner of the room just for the sake of tradition.

Forests Forever?

Over the past several years we have joined the many voices sounding the alarm about the health of California forests. We have included a number of articles on this website regarding California's ailing forests. About ten years ago while walking the PCT between Cottonwood Pass south to Walker Pass, the number of unhealthy trees was difficult to ignore. And since then, persistent drought and incursion of pests have made things worse. Erik Vance's piece also includes another factor in the deterioration of forest health . . . over-crowding and the resulting competition for water/nutrients/sunlight.

Vance also notes that the casualties are not equally distributed between tree species with the red fir being particularly at risk.

California’s iconic mountain forests are in serious trouble, according to a series of recent studies. The latest — an aerial survey of the state’s most forested regions — shows that a combination of drought and insect damage wiped out a startling 36 million trees between 2021 and 2022.

“These last three years have been the hardest, driest three years on record in California,” said Jeffrey Moore, a forester with the U.S. Forest Service and the lead researcher on the survey, which was conducted from July to October. “When you get talking about multiyear exceptional drought, I mean, it’s rough on everything.”

The death toll wasn’t the highest we’ve seen in recent years, but it was troubling because of the type of trees that died and where they were. There are perhaps 40 species of native evergreen species in California, but more than three-quarters of the dead trees detected last year came from one family: firs.

These Christmas-tree-looking conifers are found mostly at higher elevations where there’s more snow. Half of the dead trees in the study were red firs, a crucial alpine tree in places like the Lake Tahoe area, which had avoided the worst effects of the drought until now.

Likewise, the Douglas fir had resisted the drought by using its deep roots to pull up water. But last year saw a shocking 16 times more dead Douglas firs than the previous one. In other words, the trees that should be the most able to survive the drought are now dying in large numbers.

“Doug fir is probably one of the most resilient species in the Sierra Nevada,” said Scott Stephens, a forestry professor at the University of California, Berkeley. “It is the last species that actually has not been really significantly impacted.”

Losing so many mature, drought-resistant trees can be devastating to delicate mountain ecosystems, and it indicates that the forests of the Sierra cannot withstand many more dry winters. And, of course, all of those dead trees may become a fire hazard. A study from last July showed California had lost an area of forest land nearly the size of Delaware since 1985, largely from wildfires.

What’s causing this die off? In effect, it’s a one-two-three punch, Stephens said. First, over the last 100 years, California forests have gotten more crowded, thanks to policies like fire suppression. He and several colleagues recently showed that 60 percent of lower pine forests in the Sierras are so crowded, the trees are essentially choking one another for water and nutrients.

Then came drought. The already thirsty trees reached a breaking point and many started to die. Lastly, pests like the fir engraver beetle arrived and made a meal out of the already desperate trees.

Stephens said California needed to begin managing its forests preemptively to withstand drought. The best way to do this, he said, is selectively thinning out smaller trees and clearing dead ones before they become a fire risk.

It’s not all bad news though. For one thing, about a third of the dead trees from the U.S. Forest Service survey were white firs, which are the forest version of garden weeds. They grow fast and push out trees like red firs that create a healthier ecosystem. With them gone, it’s possible other species might have a better chance.

Also, there has been a lot of snow this winter in the Sierras, which means the remaining trees will soon be healthier and better able to fight off pests. But Moore said he’s ready for at least one more bad year, since many of the trees that died last summer, including oaks in the lower elevations, weren’t spotted by the last aerial survey, because they hadn’t turned brown yet.

Stephens said: “We’re quite fortunate this year that we were able to recharge the soils. We’ll have to watch, but it’s certainly better than being another drought year.”
