“Trees are sanctuaries”*…
John Lewis-Stempel recounts a day in the life of an oak and the creatures that call it home…
Our friends the trees have an unremarkable life, or so it seems to us. They come into leaf, their fruit drops, or is gorged on by birds and the winds of autumn strip them of their dressing to leave them as the cold, bare sentinels of winter.
However, if we were to stand, tree-like ourselves, in a British copse and watch a single oak tree for an entire 24 hours — say when spring hatches out of winter — what would we see?…
Among their deceptively inert branches, trees shelter feathered Pavarottis, scuttling beetles, opportunistic fungi and fierce owls. A quick– and delightful– course in woodland ecology: “A day in the life of an oak tree, from mistle thrush in the morning to mice at midnight,” from @JLewisStempel in @Countrylifemag.

As we deliberate on the deciduous, we might send fertile birthday greetings to John Bartram; he was born on this date in 1699. An American botanist, horticulturist, and explorer, based in Philadelphia for most of his career, he was judged by Swedish botanist and taxonomist Carl Linnaeus to be the “greatest natural botanist in the world.”
He started what is known as Bartram’s Garden in 1728 at his farm in Kingsessing (now part of Philadelphia)– considered the first botanic garden in the United States. His sons and descendants operated it until 1850; it still operates under a partnership between the city of Philadelphia and a non-profit foundation, and was designated a National Historic Landmark in 1960.
“Round and round they went with their snakes, snakily”*…
Florida…
Burmese pythons are too good at what they do — they’re nearly undetectable to both humans and their prey, they barely need to move and when they do they’re deadly. On top of that, they have lots of babies.
As a result, according to an ambitious new paper produced by the U.S. Geological Survey, their population has exploded in only 20 years from a few snakes at the southern tip of Everglades National Park to an invasion that envelops the southern third of Florida…
The success of these snakes, which are native to Southeast Asia, and came here via the exotic pet trade, has been a cataclysmic failure for South Florida ecosystems and “represent one of the most intractable invasive-species management issues across the globe,” said the paper…
When biologists open the invasive snakes up, it’s like rifling through a Florida field guide. All told, they’ve found 76 prey species inside the snakes. That includes lots of birds, such as vultures, crows, ducks, herons, roseate spoonbills and threatened wood storks; small mammals such as the endangered Key Largo woodrat and Key Largo cotton mouse, marsh rabbits, armadillos, possums, raccoons, otters and domestic cats, and larger prey including domestic goats, white-tailed deer, wild hogs and alligators….
How much damage have they done? Guzy points out that before 2000, researchers could frequently spot mammals in Everglades National Park. But from 2003 to 2011, the frequency of mammal observations [raccoons, opossums, bobcats, rabbits, gray foxes, and white-tailed deer] declined by 85% to 100%. Outside the python’s range, those species were more common.
Snakes on a plain: “Python invasion has exploded out of the Everglades and into nearly all of southern Florida,” from @SunSentinel.

As we tread carefully, we might recall that it was on this date in 2006 that New Line Cinema ordered five days of additional shooting on what had been a minor film in their 2006 line-up, Pacific Air Flight 121 (principal photography had wrapped in September 2005). While re-shoots normally imply problems with a film, the producers opted to add new scenes to the film to change the MPAA rating from PG-13 to R and bring it in line with growing fan expectations… expectations that had been raised when (at star Samuel L. Jackson’s insistence) the film’s title had reverted to its original working form: Snakes on a Plane.
More than 450 snakes were used for filming to represent 30 different species of snakes, including a 19-foot (5.8 m) Burmese python named Kitty.
