KU Field Station’s spring burning begins with Prairie Acre on campus

Mon, 03/12/2018


LAWRENCE — Take a country drive in Kansas on an early spring evening, and you may witness the otherworldly sight of prairie fires. Controlled, or prescribed burns, mimic the means by which natural forces—and later Native Americans—maintained the prairie ecosystem.

Over the next few days, research staff of the Kansas Biological Survey and the KU Field Station are conducting prescribed burns in several areas of the Field Station and on the Lawrence campus.

The burns began late last week at KU’s Prairie Acre, just down the hill from Watson Library. The burn regimen is part of the Prairie Acre Restoration Project, a joint project among the KU Center for Sustainability, the Environmental Studies Program and the Kansas Biological Survey. Support for the restoration project has come from the Douglas County Community Foundation's Elizabeth Schultz Environmental Fund and other private sources.

Burning continued at the Field Station’s core area just north of Lawrence, with operations staged from the Research and Operations Center, including the Armitage Education Center.

Announcement of each burn takes place on short notice, which is typical for prescribed burns.

“Scheduling a burn is entirely weather-dependent,” said Sheena Parsons, a Biological Survey associate researcher and a certified wildland firefighter. “There’s a window of time for burning in winter before our native plants emerge. Within that time period, you watch the weather — particularly wind speed and humidity — constantly. The burn crew is prepared to come together quickly.”

A permit from the county must be obtained for every burn and is issued the day of the burn. The burns are critical for maintenance of areas upon which many research studies depend.

Smoke from fires at the Field Station’s core area (about 1,800 acres) often is visible from KU’s main campus. Tracts at the core area on a regular burning rotation:

  • The small restored prairie just outside the Armitage Education Center, a popular site for KU faculty and staff retreats;
  • the Rockefeller Native Prairie and the restored prairie adjacent to it (an ADA-compliant public trail runs through this area);
  • other native prairie and managed grassland areas at the northern end of the Field Station;
  • grassland areas in the watershed of Frank B. Cross Reservoir, a model reservoir for research and teaching; and
  • research projects at the Field Station requiring burning as a part of their scientific protocol.

Burning also takes place at the Field Station’s Anderson County Prairie Preserve about 60 miles south of Lawrence. The 1,450-acre preserve is owned by the Nature Conservancy and maintained by the Biological Survey as part of the KU Field Station for university research projects. Staff members will burn several hundred acres there. Each crew is made up of eight to 10 people from the Kansas Biological Survey. Several vehicles with water tanks are used to follow the highest standards of safety.

Daily operation and maintenance of the entire 3,800-acre KU Field Station is a complex, varied and ever-changing responsibility managed by three people. Operations Manager Bruce Johanning and Research Associate Vaughn Salisbury have managed burns for many years. Parsons joined the Field Station staff at the beginning of this year after managing field experiments of Bryan Foster, professor of ecology & evolutionary biology, and greenhouse experiments of Jim Bever, Foundation Distinguished Professor of Ecology & Evolutionary Biology. Both Foster and Bever hold joint appointments as senior scientists at the Kansas Biological Survey and work from laboratories at the survey offices in KU's West District.

The Kansas Biological Survey, a university research center, was established at KU in 1911. It houses a variety of environmental research labs and remote sensing/GIS programs, and it manages the 3,800-acre KU Field Station, a site for study in the sciences, arts and humanities.
