Calm Down Pt. 2 đ
Just a little clarification from Bristlecone pine: Please watch ON YouTube. That way my site there gets credit for views. And please, like and share with any nature-lovers you know. I’m only kind of weird.
From The Treetalker
Haven’t posted in quite some time, partly because good news about Nature was becoming hard to find. I’ve published some books about North American trees, which I’ve mentioned before. With this new series of posts, I’m sharing short videos I’ve begun posting on Youtube which share Q&A sessions I’ve done with different trees. Here are the first 3, and I will post more later. If you enjoy them, please give them a đđ» and subscribe ( I post new ones about every 4 days) and please share with anyone you think will like hearing from Nature, up front and personally. đ
Treetalkerâwhat’s happening
I’ve looked at several articles, more or less recent, about the future of Wind turbines, as a part of the government’s plans for investing in green energy. Rather than recite the articles themselves, I’m just going to give you my general impression and opinion. Lots of opinion. You may comment, if you like.
There has been a lot of effort into establishing wind power as a more significant portion of energy sources in the US. Biden has gotten the military to agree to a couple of big offshore development areas on the West Coast (you can bet there will be a lot of protest about that.) So, now there is a lot of research and development on remote, floating ocean wind turbines, which would be on huge platforms, as opposed to the ones that are near shore, imbedded in the rock off the coasts.
These things cost a ton of money to make, transport and install, I might add, and only last 20-25 years. Sure, they give us green energy, but their production involves a lot of materials that are anything but green. They are made of all kinds of the normal stuffâsteel, plastic, tons of concrete, etc., etc.âand something called rare earth elements (REE), that are part of the magnets that operate the turbines themselves. There’s lots of REE in the earth, but it’s mixed with a lot of other things, so it’s difficult, messy and polluting to mine and process the ore, also, the mining and processing uses vast amounts of water, which is becoming a rarer commodity as time goes on (that’s another issue, however).
We do have one large mine, the Mountain Pass Mine, southwest of Las Vegas, that is scheduled to start processing (rather than sending it to China to be processed) in 2022. It was owned by Molycorp, Inc., which went bankrupt; it’s since been sold to MP Materials. Anyway, you’re welcome to look up information on all that, if you like.
So, anyway, these REE are expensive, hard to come by, and cause a lot of global tension. I mean, why do you think the U.K., Russia, the United States, and now China, have worked so hard to get into Afghanistan? Because they have LOTS of REE in all those mountains, as a largely untapped resource. It would be a huge coup for China to acquire REE in quantity. But with the way things are in Afghanistan and the way the Chinese like to run things, I think it’s going to be very interesting to watch what happens. Good luck to them, I say, and “watch this space,” as the saying goes.
However, I found that there is at least one company, Greenspur Renewables, that is working on turbines that do the job without the use of REE. I know they’re currently operating, but don’t know a lot more than that, so I don’t want to say, “Hey, go out and invest in these guys!”
So this has not been an article that is particularly pro wind energy, but I believe that there will be those who will invent what is needed to move us forward without creating even more pollution. It will take the market to drive it, tho, which is why I think the Afghanistan/China situation is so interesting.
Dragonfruit
Also called âpitahayaâ by the Maya, the Dragon fruit is an often-cultivated species of fast-growing, vine-like, tropical cactus. Quite sensitive to temperatures below freezing, it is only grown within a global range that will also not exceed temperatures greater than 100 degrees.
Originating in Central America, this perennial can attach itself to branches, rocks, walls, houses or any other surface upon which it can gain a foothold. It is primarily grown as a fruit crop, but is also considered an ornamental, although it can spread out of control. (from Volume 4-upcoming someday đ
My Blog – 10/2/2021
I’ve been watching the newsâlike, a LOTâ for a few years now, but I just can’t take this shrill, incessant harping on whatever’s going on in Congress. I mean, for God’s sake, just leave them to it! Sure, people should call their Congressman and Senators to let them know how we feelâpolitely, I might add, with no profanity or threatsâbut the press (and I LOVE the Free Press) needs to take a chill pill. There are LOTS of other things going on in the world, that just might be interesting and informative, and things that might actually be useful to our lives.
I’m not the kind of person who buries my head in the sand about what’s happening to the planet or even what’s happening with us “just folks” in America, but I think the press does not help the situation by dwelling on the negative, almost exclusively, except for the odd human interest story.
I understand that we pay more attention to what’s negative, but it’s a loop that feeds itself, and it doesn’t make for happy, healthy people. Angry people are not healthy.
So turn it off for a while. Watch the football game, or “Dancing with the Stars” or a rerun of the X-Files. Or go out and play catch with the kids.
News from The Treetalker
Brazil is going Veggie!
An article in the NYTimes, December 26, 2020 reported that Brazil is experiencing a dramatic increase in vegetarianismânow up to 30 million people, giving rise to a âbooming plant-based industry that is seeking to turn meatpacking plants obsolete.â
Brazil is the worldâs largest exporter of beef, which is one of the main causes of the alarming increase in deforestation of the Brazilian rain forest, often called the âlungs of the planet.â The attention that has been brought to this issue, as well as the voices of animal rights groups, have helped to change the appetites of Brazilians, but the driving factor is a desire for better health. Brazilians have become fatter and sicker after adopting âwesternâ diets and lifestyles.
As a result, plant-based food companies are developing new plant-based replicas of burger patties, chicken breast alternatives and imitation salmon, to name a few. Some of them are exporting their imitation meatballs, ground beef and sausage to Europe and Latin America and believe Brazil has the potential to become a major plant-bases food exporter.
The worldâs largest meat-processing company, Brazil-based JBS, has come under fire for its role in illegal deforestation in the Amazon. It has taken note of the competition, and is now expanding their sector of plant-based products that have the same texture and taste as meat.
Spotlight OnâBlue-crowned Motmot
With a long, thin tail that ends with two round feathers shaped like little tennis rackets, this colorful bird is about sixteen inches in total length. They swing these tail feathers back and forth, like a pendulum, earning them the nickname âclock birds.â
It has green, olive and electric blue feathers that give its more common name, although its flights are short and quick, so they are seldom seen, flying through the dense rainforests. It prefers to sleep there at night, but when they itâs time to build a nest, that is dug in the shape of a several-foot-long tunnel. Excavation is coordinated with the rainy season, making the digging easier; so, by the time breeding begins, the hole doesnât attract the interest of predators.Â
Blog
 I have been pleasantly surprised at our current president’s ability to manage the myriad of issues that have landed on his plate in the short time since he’s been in office. As much as I liked some of the other candidates, I don’t think they would have had the capacity, experience or judgment to cope. I also think it’s depressing how difficult the previous administration made it for him to get things moving in the beginning, and how far off the rails the opposing party has gone. But that’s a whole other topic.
   I’m not fooling myself as to how things stand. January 6th should be a wake-up call to everyone in this country, that there is, and always has been, a group of people who, as far back as the inception of the country, believe that only white people are truly human and deserve any kind of rights. They’ve been stewing in resentment since the end of the Civil War, periodically trying to put them n*****s back in their place. One can assume they’d be happy to see slavery re-established.Â
    I’m not sure what could ever be done to change the minds of people like that, or stop the influence they have on their children that makes this frightful state of mind continue, generation after generation. It seems that religion or common sense have no effect.
     But. . . back to the original topicâI guess we’ll see if this guy is able to bring the country together enough to save us from ourselves. He certainly seems to believe it’s possible. I guess I’m too much of a glass half-empty kind of person, because I’m afraid this undercurrent of anti-government and racism has been allowed to break out of the civil constraints by which it had felt bound for so long.
     On the other hand, we’ve been here before. I do think that it is important to deal with the voting rights issue, and soon. Personally, I believe that something will transpire, in pretty short order, but do hope that he doesn’t wait too long.

Diego, the Tortoise Whose High Sex Drive Helped Save His Species, Retires
With the future secured, heâs finally going home. Good job, Diego.
By Aimee Ortiz
Jan. 12, 2020
A member of the giant tortoise species indigenous to Española Island in the Galåpagos in Ecuador, Diego was one of 15 tortoises in a captive breeding program at the Fausto Llerena Tortoise Center on the island of Santa Cruz.
Among the males, Diego displayed an exceptional sex drive, so much so, heâs credited with helping save his species from extinction. Approximately 40 percent of the 2,000 tortoises repatriated to Española Island are estimated to be Diegoâs descendants, officials said.
Now, more than 100 years old, he is retiring, since the GalĂĄpagos National Park announced the end of the breeding program, saying an evaluation showed it had met its conservation goals. (Maybe he doesnât want to quit now!!)
Begun in 1965, the program on Pinzón Island started with the last 2 males and 12 females, plus Diego, a 30-year old male from the San Diego Zoo who is believed to have been taken from Española Island in the 1930s.
For many years, feral goats overran the island, competing for food and destroying the habitat. Conservationists have worked to restore the islandâs habitat, including the growth of cacti, which are a main source of food for the tortoises.
There are more details on the breeding program here.     And here.

Climate Crisis Will Reshape Finance,
Andrew Ross Sorkin,
January 14, 2020
Laurence D. Fink, the founder and chief executive of BlackRock, announced Tuesday that his firm would make investment decisions with environmental sustainability as a core goal.
BlackRock is the worldâs largest asset manager with nearly $7 trillion in investments, and this move will fundamentally shift its investing policy â and could reshape how corporate America does business and put pressure on other large money managers to follow suit.
Mr. Finkâs annual letter to the chief executives of the worldâs largest companies is closely watched, and in the 2020 edition he said BlackRock would begin to exit certain investments that âpresent a high sustainability-related risk,â such as those in coal producers. His intent is to encourage every company, not just energy firms, to rethink their carbon footprints.
âAwareness is rapidly changing, and I believe we are on the edge of a fundamental reshaping of finance,â Mr. Fink wrote in the letter, which was obtained by The New York Times. âThe evidence on climate risk is compelling investors to reassess core assumptions about modern finance.â
In recent years, many companies and investors have committed to focusing on the environmental impact of business, but none of the largest investors in the country have been willing to make it a central component of their investment strategy.
In that context, Mr. Finkâs move is a watershed â one that could spur a national conversation among financiers and policymakers. However, itâs also possible that some of the most ardent climate activists will see it as falling short.

Climate Fwd – One Thing We Can Do: Fix Recycling
by Eduardo Garcia,
January 15, 2020
For years, we relied heavily on recycling operations in China to take our waste. But that came to an end in 2018, when Beijing barred the import of recycling materials. The result is a waste crisis that has caused at least dozens of municipalities to cancel curbside recycling programs, with many more implementing partial cuts. Huge amounts of recyclables are now going to landfills.
Experts say that we would need to implement changes across the board. Legislators may need to pass laws requiring manufacturers to use more recyclable materials, companies would need to build much-needed recycling infrastructure and people would need to recycle properly.
Cities canât do all that. But they can play an important role.
For a possible model, consider San Francisco, which runs one of the most successful waste-management programs in the United States. Through recycling and composting, the city manages to keep around 80 percent of its waste out of landfills.
San Franciscoâs program has been years in the making. In 2000, it introduced the âfantastic threeâ citywide curbside collection program with separate, color-coded bins for recyclables, compost and trash. In 2009, it passed a law requiring residents and businesses to separate their waste.
Other policies include bans on hard-to-recycle items including single-use plastic bags and polystyrene packaging and an ordinance requiring food vendors to use compostable or recyclable food containers.
San Franciscoâs system is built on a highly unusual partnership with a single waste company. That company, Recology, has had a monopoly on handling San Franciscoâs waste for almost 90 years. That no-bid, no-franchise-fee concession has come under harsh criticism over the years.

Also, in “Spotlight On” –
Glistening Inkcap
This is a common edible fungus found all over the world. It grows in dense clusters on rotting hardwood and disturbed ground sites. Under humid conditions, it can also grow indoors on rotting wood. In one instance it was discovered about four hundred feet underground in an abandoned coal mine, growing on wooden gangways and props used to support the roof. The Glistening inkcap can be highly productive, with several successive crops appearing during one fruiting season.
The entire cap surface is covered with reflective cells that look like flakes of mica, which give this mushroom its name.
It is edible, and is enjoyed in omelets and sauces. Nutritionally, it contains a very high concentration of potassium, but also accumulates heavy metals from exposure, so it should not be collected from roadsides and other areas that may be exposed to pollutants.
The scientific community has found the Coprinellus micaeus of interest since 1601, when it was the subject of a monograph by Carolus Clusius in The History of Rare Plants. As this mushroom is plentiful and easily grown in laboratories, it has often been the subject in studies of cells and the processes of spore production.
Bioactive compounds have been isolated from Coprinellus micaeus. One was found to inhibit the enzyme that aids cancer cells to resist chemotherapy, and one has been shown to have some modest potential as an antioxidant. (From Volume 1 of Secret Voices, Coastal Redwood Companions)

Let’s Talk About Fire…
Reducing Fire, and Cutting Carbon Emissions, the Aboriginal WayÂ
As blazes rage in southern Australia, Indigenous fire-prevention techniques that have sharply cut destructive bushfires in the north are drawing new attention.
Thomas Fuller, NYT, Jan. 16, 2020
Photo by Matthew Abbott
Traditional Aboriginal practices of burning, which reduce the undergrowth that can fuel bigger blazes, are attracting new attention as Australia endures disaster and confronts a fiery future.
Over the past decade, fire-prevention programs, mainly on Aboriginal lands in northern Australia, have cut destructive wildfires in half. These programs, first given government licenses in 2013, now cover an area three times the size of Portugal. Even as towns in the south burned in recent months and smoke haze blanketed Sydney and Melbourne, wildfires in northern Australia were much less severe.
These efforts draw on ancient ways, but have a thoroughly modern benefit: Organizations that practice defensive burning have earned $80 million under the countryâs cap-and-trade system as they have reduced greenhouse-gas emissions from wildfires in the north by 40 percent.
They are also generating important scientific data, and are held up as a model that could be adapted to save lives and homes in other regions of Australia, as well as fire-prone parts of the world as different as California and Botswana.
âThe Australian government is now starting to see the benefits of having Indigenous people look after their lands,â said Joe Morrison, one of the pioneers of the project. âAboriginal people who have been through very difficult times are seeing their language, customs and traditional knowledge being reinvigorated and celebrated using Western science.â
In some ways, the Aboriginal methods resemble Western ones practiced around the world: One of the main goals is to reduce underbrush and other fuel that accelerates hot, damaging fires.
But the ancient approach tends to be more comprehensive. Indigenous people, using precisely timed, low-intensity fires, burn their properties the way a suburban homeowner might use a lawn mower.
The preventive fires must be timed according to air temperature, wind conditions and humidity, as well as the life cycles of plants. Northern Aboriginal traditions revolve around the monsoon, with land burned patch by patch as the wet season gives way to the dry.
The pioneering defensive burning programs in northern Australia came together in the 1980s and â90s when Aboriginal groups moved back onto their native lands after having lived in settlements under the encouragement, or in some cases the order, of the government.
Depopulated for decades, the land had suffered. Huge fires were decimating species and damaging rock paintings.
The Aboriginal groups ultimately teamed up with scientists, the government of the Northern Territory and the Houston-based oil company ConocoPhillips, which was building a natural gas facility and was required to find a project that would offset its carbon emissions.
According to calculations by Mr. Edwards, wildfires in northern Australia burned 57 percent fewer acres last year than they did on average in the years from 2000 to 2010, the decade before the program started.

California Today: Native Solutions to Big Fire
Thomas Fuller, NYT, January 24, 2020
Photo by Alexandra Hootnick
As many parts of the world grapple with how to reduce destructive, out-of-control wildfires, Native North American burning techniques have come into the spotlight, as well.
The experience in northern Australia has been critical. Researchers have used satellite data to calculate that an Aboriginal burning program started seven years ago has cut hot and destructive wildfires in half and reduced carbon emissions by more than 40 percent.
With Californiaâs Could something similar be done in California?
Margo Robbins, a member of the Yurok, Californiaâs largest Indian tribe, traveled to Australia two years ago and saw many similarities with her own cultural burning practices.
In 2014, Ms. Robbins helped organize a burn of seven acres on the Yurok reservation. A crew of 20 prison inmates brought by Cal Fire worked with the tribe to conduct the burn.
âThe No. 1 priority for our community was to bring fire back to the land. The land needs fire in order to be healthy,â said Ms. Robbins, a basket weaver who relies on the long and pliable shoots that emerge from burned hazelnut bushes.
The Nature Conservancy assists with a yearly controlled burn on the Yurok reservation in Northern California. The 2014 burn rekindled the tradition and now happens every year.
Don Hankins, a fire expert at Cal State, Chico, estimates that, at most, a few thousand acres are burned in California every year using traditional cultural burning techniques. This is tiny compared with the Australian program, which covers close to 90 million acres, around the size of Montana.
But Mr. Hankins and tribal fire experts say there seems to be an appetite in California to better understand and expand tribal burning practices. Native American burning traditions are similar to Aboriginal ones in the way that they look to nature for signals on when to burn.
Mr. Tripp says it is crucial not to interrupt natural reproductive cycles with fire â nesting birds, flowering plants â but to burn in ways that encourage growth of critical plants like hazelnut bushes and acorn-bearing oaks.
As with other Native fire experts, Mr. Tripp, who is deputy director of the Karuk tribeâs Natural Resources Department, says he is working with the National Forest Service, Cal Fire and the Bureau of Indian Affairs to obtain more sovereignty over fire.

Also, “Spotlight On” the Walking Stick Insect
Walking stick
From the Ancient Greek phasma, meaning “a phantom,” the Walking stick, or Stick insect, is a master at disappearing into its surroundings. This insect and its cousin, the Leaf insect, are normally green or brown. Also useful in self-protection is its ability to enter into a motionless state that can be maintained for a long period. The only predator from which the Walking stick has no defense is the bat, which hunts by echolocation.
Only certain species of animals can reproduce by parthenogenesis, most notably insects, but also reptiles, and it was recently discovered, sharks. This is the process by which an unfertilized egg produces an offspring. (From Volume 2, Staghorn Sumac)
