In my experience the municipal land development ordinances or standards and specifications will address trees. Some jurisdictions are very protective of their trees. The Gulf Coast has some beautiful Live oaks and diligently regulates these trees. The approved list of trees required by many jurisdictions is not particularly new and is to ensure people do not plant invasive species not natural to the area. Think "kudzu." Kudzu was introduced from Japan in the late 1800s and now spreads over several hundred thousand acres annually. Nasty stuff.
