This slow-growing evergreen tree reaches on average 100 to 115 feet tall, but very old trees may reach up to 150 feet with stout branches and an irregular crown. Historically, the Longleaf Pine forest ecosystem dominated much of the Southeastern U.S., but only small fragments of this forest remain today. This is an important tree for bird species such as the endangered red-cockaded woodpecker and the bald eagle, both of which prefer the Longleaf Pine for nesting. It grows best in full sun and dry, deep, and sandy soils.
