Wilma H. Schiermeier Olentangy River Wetland Research Park

 

The Wilma H. Schiermeier Olentangy River Wetland Research Park (ORWRP) is owned and operated by The Ohio State University with the mission of furthering the research, teaching, and outreach of wetlands, and aquatic sciences in general.  The ORWRP is a complex of freshwater riverine and wetland habitats, supporting numerous bird species, diverse fish and invertebrate communities, and a wide variety of mammals, amphibians, and reptiles.  At the center of the ~35-acre site are two experimental wetlands that are fed with water from the adjacent Olentangy River.  Created in 1993 these experimental wetlands have been the focus of wetland and aquatic science research for over 23 years.  In addition, the site has a created oxbow wetland and restored bottomland hardwood forest, both fed by the Olentangy River.  The site is also home to the 10,000 sq. ft.  Heffner Wetland Research and Education Building.  This research facility contains teaching, analytical, and wet labs as well as a 65-person classroom and offices for researchers focused on water resource science and education.

Ecology

  • Approximate size (ha):

    14
  • General wetland characterization:

    Inland Fresh Seasonally Flooded Basin/Flat, Inland Shallow Fresh Marsh
  • Adjacent water bod(ies)

    Stream
  • Approximate stream order

  • Name of body of water

    Olentangy River
  • Surficial geology

    The geology of the ORWRP is Wisconsinan Till which is an unsorted mix of silt, clay, sand, gravel, and boulders (geosurvey.ohiodnr.gov).

  • Soils

    The wetlands are primarily within the Ross silt loam (occasionally flooded) soil type.  There is a portion of the site (~16%) that is Eldean silt loam (2-6 percent slopes) but this area is mostly covered by site infrastructure (e.g. research/teaching facility, driveway, research compound, etc.).
