Foto de stock de Large Tree Burl Growing on Trunk in Early Spring Forest

A large woody burl forms on the side of a deciduous tree trunk, creating a dramatic and irregular growth in an early spring forest. Burls are abnormal swellings caused by stress, injury, infection, or fungus, where dormant buds grow uncontrollably into a dense, knotted mass. Though often appearing unusual or grotesque, burls do not typically harm the tree and are prized by woodworkers for their intricate grain patterns. Their presence in the forest reflects natural resilience, adaptation, and the complex ways trees respond to environmental conditions.
