Northeastern Iowa, along the Upper Iowa River, is a natural draw for biologists. Known as the Driftless Area, this part of the Upper Midwest escaped the most recent glaciation and features rugged topography with a great variety of natural habitats.
The areas that surround campus are a vital component of students’ education in biology. Because of their easy accessibility, many of the natural areas are used by hundreds of students each year for field “labs.” The diversity of habitats and ongoing restoration projects provide many opportunities for student research projects.
Spilde Woods and Hickory Ridge Woods are mature hardwood forests with several species of oak, hickories, walnuts, and maples. They are used by students in biology classes to study forest ecology. In the early spring, blue bells, Hepatica, and spring beauty are common on the forest floor.
Roslien Woodlands is a former pasture that was planted to hardwoods and conifers to restore the soils. The conifers are being removed as the hardwoods grow larger.
The Upper Iowa River runs through the Luther College property. The Invertebrate Zoology course monitors benthic macroinvertebrates within the river.
Hoslett Study Area is located along the Upper Iowa River and has an interesting mix of plant species adapted to rich floodplain soils. Funds from the Emergency Watershed Protection program allowed Luther College to restore additional land along the Upper Iowa River Floodplain. In 2011, native trees and prairie species were planted. Students will be involved in monitoring the progress of the ecological restoration of these areas for years to come.
Lindeman Pond is one of several ponds on campus used by students in biology courses. The pond has painted turtles, spring peepers, and bluegill, as well as microscopic organisms studied by microbiology students.
Gateway Prairie is a 39.3-acre prairie and oak savanna established in 2005 along the east side of Highway US-52 immediately adjacent to the Upper Iowa River, with the goal of helping reduce soil erosion during flood events and providing recreational and aesthetic benefits to the Decorah community. Formerly a highly erodable agricultural field, the prairie was planted with over 70 species of native plants. Burn breaks within the prairie are used by the cross country team as part of their race courses.
Anderson Prairies is a 27-acre reconstructed tallgrass prairie that prior to 1988 was used for row-crop agriculture by the college farm. Planted in 1988 and expanded in 1998, the goal was to reduce soil erosion.
Students in several biology and environmental studies courses use these sites to learn about prairie ecology.
Lionberger Environmental Preserve includes an upland oak-hickory forest, Ten Mile Creek, a spring-fed pond, a floodplain forest, several open grassland areas, and limestone bluff outcrops. Students in the Botany, Ecology, and Entomology courses regularly use this area for field studies.
Freeport Marsh is an unusually large spring-fed marsh with several plant species that are rare in Iowa; including skunk cabbage, alder, and sweet flag.
