 Golf course superintendents monitor the health of the golf course environment through study, diagnosis, and treatment of disease and injury to the golf course’s turfgrass fairways, tees and greens areas, as well as bunkers, areas of water hazard, naturalized areas and trees.Their management of the course is accomplished through a knowledge of biology, chemistry, plant pathology, and entomology.In the United States, golf course superintendents can be certified by the Golf Course Superintendents Association of America (GCSAA).
