National Champion Trees are the largest known specimens of their species in the United States. They are recognized by the National Big Tree Program, which is managed by the American Forests organization. These trees are measured based on their height, trunk circumference, and crown spread, and they represent the best examples of their kind. Each National Champion Tree is a symbol of natural heritage and biodiversity. They are often located in parks, forests, or private properties, and their preservation is important for ecological balance. The program encourages the public to discover and appreciate these magnificent trees, fostering a greater understanding of forestry and conservation efforts.
