In 1928 the Lake States Forest Experiment Station of the U. S. Forest Service began studies of various races or strains of red pine (Pinus resinosa Ait.), to find out how well red pine is adapted to climatic regions distant from its natural seed sources.
In the Lake States, in New England, and in the Middle Atlantic States thousands of acres of abandoned farm land and land denuded by ax and fire have been planted with red pine (Pinus resinosa Ait.).
