NATURE: A sampling of the most spectacular trees in the world

Image via sea turtle on Flickr

This series is in no way meant to be exhaustive but merely a sample of nature’s most spectacular trees — available to you via the Internet and by people who have decided to share their images via a creative commons license. Wikipedia also has a list of famous trees that are of “historical, national, locational, natural or mythological importance,” and there’s a list of oldest trees too. Another resource is the National Register of Big Trees.

  1. The dragon’s blood tree (Dracaena cinnabari) is a “distinctive and slow-growing” tree that looks otherworldly. These bizarre-looking trees are “native to the Socotra archipelago off the horn of Africa[, and] the famous red resin . . . gives it its name.” More via Atlas Obscura:

    The island of Socotra is part of an archipelago in the Indian Ocean. It is so isolated that a third of its plant life is found nowhere else on the planet. Notable are the dragon’s blood trees that look like flying saucers perched on trunks.

  3. Like the dragon’s blood tree, Adenium obesum socotranum is also endemic to the island of Socotra. Its appearance is reminiscent of the smaller baobabs of Madagascar.

  5. BaobabsAdansonia sp., consist of eight species, which are naturally found on the continents of Africa and Australia. Six species are native to Madagascar, so Madagascar has the highest endemism. Mainland Africa and Australia both have one species. The entire genus is spectacular. The first image below shows the giant Adansonia grandidieri, which is endemic to Madagascar. This titan-sized tree is considered endangered.

  7. The Queensland bottle tree (Brachychiton rupestris) uses its trunk to store water. This tree species appears somewhat similar to the aforementioned baobabs, and it’s in the same family as the baobabs — Malvaceae.

  9. Alluadia procera is another member of Madagascar’s unique spiny forest. This species belongs to the family Didiereaceae, and all the plants that make up this family are found only in Madagascar’s spiny forest. The Didiereaceae family is intriguing, and anyone who visits Madagascar’s spiny forest will observe that this family of shrubs and trees give the spiny forest its whimsical or distinctive appearance. To me, the spiny forest looks like something out of a Dr. Seuss book. The image below shows an Alluadia procera growing in Madagascar’s spiny forest.

  11. The bristlecone pines (Pinus spp.) are some of the oldest living non-clonal organisms (distinguish from species that can form clonal colonies such as the trembling aspen (Populus tremuloides), and some clonal colonies of the trembling aspen are thought to be 80,000 years old or up to 1 million years old). Despite their old age, bristlecone pines are threatened by invasive species and climate change. From the New York Times:

    Living in extreme conditions about two miles above sea level, they have become the oldest trees on the planet. The oldest living bristlecone, named Methuselah, has lived more than 4,800 years.

    Now, however, scientists say these ancient trees may soon meet their match in the form of a one-two punch, from white pine blister rust, an Asian fungus that came to the United States from Asia, via Europe, a century ago, and the native pine bark beetle, which is in the midst of a virulent outbreak bolstered by warming in the high-elevation West.

    Blister rust is a new challenge to the pines. It spread to Europe from Asia in the 19th century and then was shipped unknowingly to the East and West Coasts of North America around the turn of the last century on nursery trees. Only now is it reaching the high-elevation bristlecone. Anna Schoettle, a Forest Service ecologist in Fort Collins, Colo., said, “Neither the bristlecones nor their ancestors have been faced with a disease like this, and they have not evolved tolerances.”

  13. The Tree of Life, located in Bahrain, is “a mesquite tree that has grown at the highest point in Bahrain for over 400 years, [and] the Tree of Life lives isolated in the desert, miles away from other vegetation and with no apparent source of water.” Most likely, the tree has tapped into a supply of groundwater. The awe-inspiring tree can be seen from space too.

  15. The giant cotton tree of Freetown, Sierra Leone, is a historic symbol. More via Wikipedia:

    The Cotton Tree is an historic symbol of Freetown, the capital city of Sierra Leone. According to legend, the “Cotton Tree” gained importance in 1792 when a group of former African American slaves, who had gained their freedom by fighting for the British during the American War of Independence, settled the site of modern Freetown. These Black Loyalist settlers, called “Nova Scotians” in Sierra Leone, founded Freetown on March 11 1792. According to tradition, they landed on the shoreline and walked up to a giant tree just above the bay and held a thanksgiving service there, gathering around the tree in a large group and praying and singing hymns to thank God for their deliverance to a free land. Today, a huge Cotton Tree stands in the oldest part of Freetown near the Supreme Court building and the National Museum. Sierra Leoneans believe that this is very tree was where the “Nova Scotian settlers prayed more than two hundreds years ago, and they regard it as the symbol of their capital city. Sierra Leoneans still pray and make offerings to the ancestors for peace and prosperity beneath the great Cotton Tree. This was especially true during the Sierra Leone civil war (1991-2002).

  17. The giant redwoods of California are spectacular because of their size. The coast redwoods, Sequoia sempervirens, are the tallest tree on Earth, while the giant sequoias, Sequoiadendron giganteum, “are the world’s largest trees in terms of total volume.” According to The IUCN Red List of Threatened Species, “Some 90 to 95% of old growth [redwood] forest has been felled since, and the remainder is now almost entirely in parks and reserves.” The image directly below shows a 300-foot giant coast redwood that is located in California’s Prairie Creek Redwoods State Park.

  19. The angel oak is a southern live oak (Quercus virginiana) located near Charleston, South Carolina. Wikipedia has some stats on this spectacular giant:

    The Angel Oak is a Southern live oak tree located in Angel Oak Park, in Charleston, South Carolina, on Johns Island, one of South Carolina’s Sea Islands. It is estimated to be in excess of 1400 years old, stand 65 ft (20 m) tall, measure 25.5 ft (7.8 m) in diameter, and shade with its crown an area of 17,000 square feet (1,600 m2). Its longest limb is 89 feet (27 m) in length. The tree and surrounding park have been owned by the city of Charleston since 1991.

  21. The rainbow eucalyptus, Eucalyptus deglupta, is a species of eucalyptus that grows on “New Britain, New Guinea, Ceram, Sulawesi and Mindanao,” and “it is the only Eucalyptus species found naturally in the Northern Hemisphere.” An entire forest consisting primarily of rainbow eucalyptus must be a magnificent sight.

  25. The Trembling Giantis a clonal colony of a single male Quaking Aspen (Populus tremuloides) located in the U.S. state of Utah, [and] all [are] determined to be part of a single living organism by identical genetic markers.” The Trembling Giant my be over 10,000 years old, and it is considered to be the largest-known organism by some authorities. Clonal groups of quaking aspens are common. Via Wikipedia and the Organisation for Economic Co-operation and Development:
    Clonal groups of P. tremuloides in eastern North America are very common, but generally less than 0.1 ha in size, while in areas of Utah, groups as large as 80 ha have been observed (Kemperman and Barnes 1976). In the semi-arid western United States, some argue that widespread seedling establishment has not occurred since the last glaciation, some 10,000 years ago (Einspahr and Winton 1976, McDonough 1985). Indeed, some biologists feel that western clones could be as old as 1 million years (Barnes 1966, 1975). It has been claimed that a single clone, nicknamed “Pando” (Latin for I spread), covers 43 hectares, contains more than 47,000 stems and weighs in excess of 6 million kg, making it the largest known organism (Grant et al. 1992, Mitton and Grant 1996)

    Due to a combination of factors, the Trembling Giant, sometimes called Pando, which is latin for “I spread,” appears to be dying. Sadly, quaking aspen forests are dying off across the western United States, but scientists are trying to save them. More via an interesting article by John Hollenhorst at ksl.com:

    Utah scientists are trying to organize an emergency rescue effort to save the largest living thing ever discovered anywhere on Earth.

    It’s known as Pando — a single organism, living in central Utah, that some scientists say could also be the world’s oldest living thing. But Pando is dying and may have only a few more years of glory.

    Pando consists of grove of quaking aspen trees spanning 106 acres in the Fishlake National Forest near Fish Lake. Scientists call it an aspen clone, which is essentially a single plant comprised of thousands of trees, connected by underground roots.

    .       .       .

    In the 1970s, scientists tentatively mapped Pando’s boundaries. More recently, Utah State University geneticist Karen Mock wondered if Pando’s reputation as the world’s largest known organism was overblown.

    “So we set out to either confirm or deny that,” Mock says.

    She took DNA samples from 209 trees, mostly within that boundary. Her testing verified what was long suspected.

    “Genetically, in fact, Pando is one enormous clone over 100 acres,” Mock says, “probably over 47,000 individual trees.”

    In all, Pando weighs about 13 million pounds, which makes it by far the most massive organism ever found.

    “There may well be some larger clones than Pando out there,” Mock says, “but it’s the largest organism that’s been described [by scientists].”

    As Pando’s fame spread, the U.S. Postal Service honored the Utah curiosity as one of “40 Wonders of America.” A postage stamp issued in 2006 surely sets some sort of a record for making something very small out of something very big.

    But now Pando is in serious trouble, according to ecologist Paul Rogers of Utah State University.

    “I would call it a crisis, yes,” Rogers says.

    When he visited Pando two years ago, the clone seemed reasonably healthy. But when he went back with a team of forestry experts three weeks ago, he was shocked.

    “We’re looking at a situation where the whole clone could crash pretty quickly here, within the next few years,” Rogers says.

    The bark of Pando’s mature trees shows they’re dying from drought and beetles. That’s typical of aspen stands throughout the West and, by itself, is not especially worrisome. But disturbingly, small trees and sprouts have vanished from the area spanned by Pando.

    “There was no regeneration and there was no mid-story tree,” Rogers says. “So if you might think of those as the young ones and the juveniles, there’s no young ones to replace those dying trees. So this set off alarm bells.”

    Rogers says there is an overabundance of deer and elk in the area and he believes the wildlife is feeding on the young sprouts. He also says a small amount of livestock grazing in the area is playing a minor role.

    Rogers wants emergency action to fence out the deer and elk. Some government agencies are looking into it, but that strategy is sure to be controversial. Fences would have to be quite high to be effective in holding out deer, and at least one rancher also has grazing rights in the area.

    Another complication is that recreationists may have concerns about a high fence in such a scenic area. A U.S. Forest Service campground adjacent to Fish Lake is actually within Pando’s biological boundaries.

    Rogers says a fence would be effective, though. A small portion of Pando — less than 10 percent — is already fenced. That part of the clone is thriving and regenerating.

    If Pando does die out or becomes sharply reduced in size, it would be particularly poignant because of the clone’s presumed age. Pando is conceivably the oldest living thing ever studied.

    The removal of wolves or key predators from certain landscapes may explain why the aspen is declining. More on this theory via an excellent article by Pete Aleshire at the Payson Roundup:

    Aspen have declined by 50 percent in Colorado, 60 percent in Utah and 95 percent in Arizona, according to a recently published study by researchers from the Forest Service’s Rocky Mountain Research Station. Study plots in many areas have shown a 50 percent decline in recent decades, with most of the stands giving way to thick forests of pines.

    .       .       .

    Aspen experts blame a variety of other factors as well. For instance, deer and elk love to browse on aspen seedlings. So some researchers think the explosion of the elk populations in the Southwest in the past 50 years may have also pushed the aspen toward extinction.

    That theory took a hit recently when researchers in Yellowstone found to their surprise that the growing number of wolves in the park hadn’t helped out the dwindling aspen.

    The U.S. Geological Survey researchers concluded that the decline of aspen in Yellowstone did coincide with the population explosion in the elk herds after the removal of the wolves in the 1890s. However, none of the dwindling aspen stands had staged a comeback after wolves returned — reducing the number of elk by 40 percent.

    Only fences that kept elk out altogether allowed some of the aspen stands to start producing sprouts from those buried roots that grew into new trees. The researchers concluded that rising elk numbers played the key role in the decline of the aspen, but the wolves haven’t eliminated enough elk yet to make a difference.

    Another study implicated drought, rising temperatures and a host of plant pests and diseases unleashed by the trends. One careful study in southwestern Colorado published in Forest Ecology and Management documented the loss of 10 percent of the aspen in one area in less than two years. The study found that a plant canker and three types of beetles played a role in killing off the biggest trees at a dismaying rate. The aspen on south-facing slopes at lower elevations suffered the greatest loss, which implicated the effects of drought and rising temperatures.

  27. The world’s most isolated tree — or what was the world’s most isolated tree rather — was known as the Tree of Ténéré. It “was a solitary acacia, of either Acacia raddiana or Acacia tortilis, that was once considered the most isolated tree on Earth — the only one within more than 200 kilometres (120 mi).” Apparently, the famous landmark was destroyed by a drunk driver. Certainly, the tree’s destruction is a metaphor for humanity’s obsession with consumption, which is inherently destructive towards nature.
  28. Image of the the Tree of Ténéré via Wikipedia

    The Tree of Ténéré “has been replaced by a simple metal sculpture representing a tree.” How ironic.

  29. The Tree That Owns Itself is a tree that supposedly has legal ownership over itself and some land surrounding it. If you find this topic interesting, then you should consider: Should Trees Have Standing?: Law, Morality, and the Environment. You can also read Christopher Stone’s original essay on this topic here. More on the Tree That Owns Itself via Wikipedia:

    The Tree That Owns Itself is a white oak tree, widely assumed to have legal ownership of itself and of all land within eight feet (2.4 m) of its base. The tree is located at the corner of Finley and Dearing Streets in Athens, Georgia, USA. The original tree fell in 1942; a new tree was grown from one of its acorns and planted in the same location. The current tree is sometimes referred to as the Son of The Tree That Owns Itself. Both trees have appeared in numerous national publications, and the site is a local landmark.

    Can an environmental object sue for its own preservation? It’s an issue that has been mentioned by the courts. Via First American Corp. v. Al-Nahyan:

    Justice William O. Douglas is famous for having proposed a unique solution to determining when a dispute involving environmental laws is properly a case or controversy-give trees legal standing to sue. See Sierra Club v. Morton, 405 U.S. 727, 741, 92 S.Ct. 1361, 31 L.Ed.2d 636 (1972) (Douglas, J., dissenting) (“Contemporary public concern for protecting nature’s ecological equilibrium should lead to the conferral of standing upon environmental objects to sue for their own preservation.”). If ever adopted, the proposal could have numerous unintended consequences-one of which would be to subject civil litigants in complex cases such as these to potential liability. For many are the trees that have died so that the parties in these consolidated cases may present their respective cases, and it would not be surprising if the trees had a complaint or two to lodge against them.

POLITICS: Christine O’Donnell channels Sarah Palin

“What opinions, of late, that have come from our high court, do you most object to?”

“What other Supreme Court decisions do you disagree with?”

Image via the Associated Press

Tea Party-backed candidates and anti-intellectuals Christine O’Donnell, who wants to serve in the U.S. Senate, and Sarah Palin, who wants to be President of the United States, do not have the intellectual curiosity needed to be a successful U.S. politician. A lack of intellectual curiosity is a real problem for the entire Republican Party.
The United States is a very complex country that faces very complex problems. Personally, I don’t believe that the Republican Party and their inadequate tools of governance — to deregulate, to promote a small government, and to lower taxes — can solve the complex problems that our country must some how tackle. If the Republican Party is to remain relevant, then they must expand the type of remedies they use to solve the country’s problems. Furthermore, the Republican Party must acknowledge complex global problems that impact the United States such as climate change, natural resource depletion, peak oil, and domestic issues such as economic recovery and large-scale job loss. More on the Delaware Senate debate via the Telegraph.co.uk:

Miss O’Donnell, 41, who is running for the senate in Delaware, invited the question when she said she opposed activist judges, citing the recent court decision ordering an immediate halt to military discharges of gays who revealed their sexuality.

But when the moderators asked her to name a recent Supreme Court decision with which she disagreed, the Tea Party favourite was unable to name a single one. Her opponent, Chris Coons, a senior official in the state, immediately answered that he disagreed with the court’s Citizens United earlier this year which loosened controls on campaign financing.

WIND ENERGY in the news

  1. Superhighway for wind power proposed for Mid-Atlantic Coast. Via the Philadelphia Inquirer:

    Investors on Tuesday proposed to build an underwater electricity superhighway that would carry wind power generated off the Mid-Atlantic Coast to land.

    The $5 billion transmission line, announced by backers including Google, would run about 15 to 20 miles offshore.

    It would act like a spine, linking the offshore projects to land at four locations – North Jersey, South Jersey near Atlantic City, the coast of Delaware and the coast of Virginia south of Norfolk.

    “This is a huge, bold project,” said Robert Mitchell, CEO of Trans-Elect, an independent transmission company operating nationwide, which is leading the project. “It’s going to result in thousands of megawatts of offshore wind being delivered to the East Coast” along with thousands of jobs.

    “Instead of multiple connections, this will serve as a superhighway with on-ramps for wind farms,” said Rick Needham, director of green business operations at Google, a major investor.

    It also would increase the reliability of wind, they said. By joining the projects together, the variability of wind at any one location is smoothed out, lulls in one place compensated for by gusts elsewhere.

  2. Google backs ‘superhighway’ for wind power. Via the Washington Post:

    Internet search engine giant Google announced Tuesday that it is investing in a mammoth project to build an underwater “superhighway for clean energy” that would be able to funnel power from offshore wind farms to 1.9 million homes without overtaxing the already congested mid-Atlantic power grid.

    The project, dubbed the Atlantic Wind Connection, calls for spending as much as $5 billion to create a 350-mile network of underwater cables stretching from northern New Jersey to Virginia. It would eliminate the need for offshore wind developers to build transmission lines of their own, easing what can be a barrier for such projects.

    Google is partnering with Good Energies, an environmentally focused international investment company based in New York, London and Switzerland, and Tokyo-based Marubeni to finance the project. The project is led by Trans-Elect, an electric transmission company in Chevy Chase.

  3. Report Identifies Transmission Corridors to Deliver 8,600 MW of New Wind in the Upper Midwest. Via Renewable + Law:

    [The Upper Midwest Transmission Development Initiative's] renewable transmission corridors are based on the Midwest ISO’s estimate that about 8,600 MW of new renewable capacity will be needed in the region by 2025 to serve the renewable energy standards and goals of these five states. The group identified twenty “wind zones” where it would be most efficient to develop wind power based on available wind resources, existing wind generation, existing interconnection queue requests, and local geography. The six transmission corridors were chosen as the best general areas for transmission lines to move wind energy from the wind zones to load centers in a cost-effective manner.

  4. In 2009, 40% of new U.S. electricity generation came from wind. Via EERE News:

    The U.S. Department of Energy has distributed the International Energy Agency’s (IEA) recently published IEA Wind Energy Annual Report 2009, which is now available for free download. The report presents the latest information on domestic and international wind generation capacity, national incentive programs, progress toward national objectives, benefits to national economies, research and development results, and issues affecting turbines, market growth, and costs of projects. The Executive Summary synthesizes the information presented from IEA’s member countries, cooperative research tasks, the European Commission, and the European Wind Energy Association. Read the Executive SummaryPDF.

    Wind power is a fast-growing source of clean energy. In the United States 40% of new electricity generation came from wind last year, while in Europe, wind power installations accounted for 39% of new capacity. IEA Wind member countries added more than 20 gigawatts (GW) in 2009, for a total of more than 111 GW of wind generating capacity. Five countries added more than a gigawatt of net capacity: the United States (10 GW), Spain (2.5 GW), Germany (1.9 GW), Italy (1.1 GW), and the United Kingdom (1 GW). Additionally, wind power electrical generation capacity grew more than 32% worldwide in 2009. These and other statistics on wind energy development are highlighted in the report.

    The IEA Wind member countries—located in Europe, North America, Asia, and the Pacific Region—contain 70% of worldwide wind generating capacity. These countries share information and research efforts to increase wind energy’s contribution to their electrical generation mix, and they reach out to other countries to join the IEA Wind cooperation.

  5. Study: Offshore wind could generate all U.S. electricity (with graphics below). Via USA Today:

    U.S. offshore winds, abundant off the coasts of 26 states, have the potential to generate four times as much power as the nation’s present electric capacity, a new Department of Energy report says.

    Developing this resource would help the United States reduce air pollution, achieve 20% of its electricity (or about 54 gigawatts) from wind by 2030 and create more than 43,000 permanent, well-paid technical jobs, according to the 240-page study by DOE’s National Renewable Energy Laboratory.
