A "National Tree" is a tree species that is designated as a symbol of a country. It often represents the nation's heritage, culture, or natural beauty. Many countries choose a national tree to promote environmental awareness and conservation efforts. Examples include the Oak in the United States and the Maple in Canada. National trees can also play a role in national identity and pride. They are often featured in official emblems, flags, and other national symbols. By recognizing a national tree, countries encourage citizens to appreciate and protect their natural resources for future generations.
