Burl or Burr on Oak

Burls are quite commonly seen here on Birch and Oak but today we came across this enormous one along a forest path on Oland. It was growing on Oak (Quercus robur) and was at least a metre in diameter.

A burl results from a tree undergoing some form of stress. It may be caused by an injury, virus or fungus. Most burls grow beneath the ground, attached to the roots as a type of malignancy that is generally not discovered until the tree dies or falls over. Such burls sometimes appear as groups of bulbous protrusions connected by a system of rope-like roots. Almost all burl wood is covered by bark, even if it is underground. Insect infestation and certain types of mold infestation are the most common causes of this condition.

In some tree species, burls can grow to great size. The largest, at 26 feet (7.9 m) occur in Coast Redwoods (Sequoia sempervirens) and can encircle the entire trunk; when moisture is present, these burls can grow new redwood trees. The world's second-largest burls can be found in Port McNeill, British Columbia. One of the largest burls known was found around 1984 in the small town of Tamworth, New South Wales. It stands 6.4 ft (2.0 m) tall, with an odd shape resembling a trombone. In January 2009, this burl was controversially removed from its original location, and relocated to a public school in the central New South Wales city of Dubbo. From Wikipedia

In Sweden Burrs are often usen for woodwork, as parts of furniture, knives, bowls, etc., as the wood is strong and hard. The wood also has a beautiful mottled pattern and a fine lustre.

In Swedish this is called a Vril while I believe the name Burr stands for English and Burl for American!

This was captured with the camera handheld. It has been reduced in size and sharpened.

Hallo Ulla
A very fascinating posting and I can only agree with what Roberto has stated. My eye caught the thumbnail in a glimpse and I thought it was a HUGE mushroom you captured, and something totally different appeared as I openend the image in full. Thanks for sharing. Best regards.

Bonjour Ulla,
Something I have rarely seen in my country. May be trees have less stress here;-)
Impresssive burl, looks like the oak would have suffered a bit, but it was strong enough to survive. Well presented natural shot and a most original and interesting posting.
Bon dimanche vous deux!
