Tyson Research Center is a 2,000-acre (8.1 km2) field station owned and operated by Washington University in St. Louis in the St. Louis, Missouri metropolitan area east of Eureka. The area was used as a munitions storage area during World War II and was purchased in 1968. It is part of the Henry Shaw Ozark Corridor which consists of over 8,000 acres (32 km2) of protected lands. It is a member of the Organization of Biological Field Stations (OBFS).
Tyson Research Center was originally part of the Tyson Valley Powder Plant in World War II. It is currently bordered to the east by Lone Elk County Park, to the west by West Tyson County Park, and to the south by Interstate 44.
Primary activities at the Tyson involve ecological research conducted by undergraduate and graduate students, staff, and faculty of Washington University and other local universities. Scientific outreach and continuing education programs and university-level courses of instruction are also occasionally held at Tyson.
