John Clayton Gifford

John Clayton Gifford (February 8, 1870 – June 25, 1949) was a naturalist and forester who was the first American to hold a PhD in forestry.

Early life and education
Born in 1870 in the Mays Landing, New Jersey, he received a BSc in 1890 from Swarthmore College and later studied forestry in Germany. He worked as an associate professor at Cornell University.

Career
In 1902, he moved to the Coconut Grove neighborhood in Miami, where he became an entrepreneur and land developer. He was an ardent supporter of draining the Everglades and started experimenting by planting Cajeput trees.

He wrote articles for the Miami Herald's Tropic magazine. He wrote The Everglades and other essays relating to southern Florida (1911).

He introduced Melaleuca trees to Florida in the 1900s. Melaleuca quinquenervia subsequently invaded large areas of South Florida, displacing native wetland and upland vegetation.
