This tree burl on an oak is one I check on regularly to see if the tree is still there. I call it the Sasquatch burl and have visited it for over 20 years.

Burls are formed when a pathogen attacks a tree or an insect burrows in and lays its eggs inside. Cell division is accelerated and the tree creates new tissue to isolate the injury and protect itself. These are also referred to as Galls or Boles. Burls are called Burrs in Britain.

Burls are often used to create unique furniture and decorative items due to their grain.
