Most often a rather scrubby tree, often occurring mixed with some oak, in forests or savanna on dry sandy soil, as in the vast areas of jack pine plains in the north central Lower Peninsula. Locally it also occurs in boggy situations with leatherleaf (Chamaedaphne) as well as on barren rocky sites (e.g., Isle Royale).
It has been estimated that jack pine predominates on perhaps half a million hectares of forest in Michigan, over half of it in the northern Lower Peninsula, where certain restricted areas of young growth are the home of our most famous bird, the Kirtland’s or “Jack Pine” Warbler, which breeds nowhere else in the world.
