PC: Grefino Forest Area
In northwestern Poland lies the Crooked Forest (Krzywy Las), a protected grove of about 400 Scots pine (Pinus sylvestris) trees that grow in a way that is out of keeping with nature.
Planted around 1930, the trees each have a sharp 90-degree bend at the base, all facing directly north, then most curving upward toward the sky. Local folklore attributes the trees’ shape to blizzards or to the time when World War II tanks passed by, but the Griffenau Forest District and researchers at the University of Pennsylvania point to human intervention as the reason for the trees’ curvature and/or design.
One leading theory among scientists is that local forests systematically manipulated seedlings until they produced timber with a “natural curve” for building ships or furniture. This industrial use of trees was likely abandoned when the Nazis invaded Poland in 1939; However, leaving behind this J-shaped puzzle.
Why was nature excluded for these 400 trees?
According to the Grefino Forest District, there will be chaotic and irregular bends in different directions due to natural forces such as wind or soil change and will not cause all trees to bend in the same direction.
The absolute uniformity of this northward orientation across the 0.3-ha orchard suggests deliberate mechanical intervention rather than random environmental factors, meaning that the entire 0.3-ha orchard has been subjected to systematic mechanical intervention.The trees’ “J” shape indicates they were held up either by stakes or man-made weights for several years while growing horizontally for 1-3 meters before turning back toward the sky, according to an analysis by the Center for Russian and East European Studies at the University of Pennsylvania.
Why did the secret of the Crooked Forest disappear?
According to the prevailing scientific hypothesis, these trees were created through the use of bentwood techniques to be used as parts of an artificial system rather than a result of nature.Before the development of synthetic materials and products, foresters manipulated trees to provide a predetermined curvature (i.e., shape) when they reached maturity. This “bent” wood has tremendous structural integrity for building ship ribs, sleigh latches, barrels, and curved furniture like rocking chairs.Historical highlights published by the University of Pennsylvania regarding this area of forest indicate that as a result of the invasion of Poland in 1939, this project will likely have to be abandoned. When the local people of Gryfino were displaced or killed during World War II, the specific knowledge and tools used to shape this orchard disappeared with them.
Why didn’t nature and war form the Twisted Forest?
A popular urban legend suggests that World War II tanks crushed young saplings during the battle, but the Grefino Forest area notes that there is no evidence of painful scarring of the bark and no indications of mechanical damage to the trees that would lead someone to believe that tanks broke the logs.
In addition, the tanks would not have left 400 trees alive, all of which were aligned to the north.As for snow theory, while heavy snow may “bend” young trees, it usually results in “keyed” or chaotic patterns. This cannot explain an entire grove of trees bent uniformly at 90 degrees from top to bottom with natural events, nor can it explain an entire grove reaching the same growth milestone (7-10 years) simultaneously to produce such simultaneous bending.
Survival biology, gravity
Scientists are studying how Scots pines use gravity. During the period of physical suppression, they produced “compressed wood” on the underside of their trunks, and reoriented themselves vertically by phototropism after all restriction or decay was removed.The entire grove is now protected as a natural monument, and the Grefino Forest District has begun a reforestation program to recreate a “new” twisted forest in the vicinity of the original twisted forest to further study the phenomenon.
