Trees are protected by laws enacted by local municipalities, state governments and the federal government to govern the care and preservation of trees, states the International Society of Arboriculture. These laws protect specific trees in specific locations, and there's no single law that protects all trees in all locations.
The trees these laws protect include historic trees, street trees in a city and native trees in a natural area or woodland, according to the International Society of Arboriculture. In some cases, tree ordinances outline stipulations for the care of trees on private property, such as the Tree Protection Ordinance in the city of Atlanta. Tree protection laws vary widely in their scope and specificity.
