MacDougal was appointed director of the laboratory. In 1909, he established a coastal botanical laboratory in Carmel, California, and he became known as the expert of Monterey pines. He later became director of Botanical Research at the Carnegie Institution in Washington, D.C. He remained there until his retirement in 1933.
