GrimesFarm and Conservation Center
2349 233rd St, Marshalltown Located off of Highland Acres
The GrimesFarm and Conservation Center is located just west of the city limits of Marshalltown. It lies on the west side of Highland Acres Road and on the north side of 233rd Street.
When Leonard and Mildred Grimes purchased their farm west of Marshalltown in 1964, they began the work to heal the then existing abuses to the land. Over the years soil erosion has been reduced by planting grasses, using no-till agriculture practices, establishing waterways, constructing terraces, building a farm pond, and planting thousands of trees. Eventually a “poor farm” was transformed into an excellent example of land that is productive, profitable, and beautiful.
Beginning in 1964, the area was used as an outdoor classroom for local 5th or 6th grade students. A day spent in this “classroom” was coordinated by the public school teachers assisted by guest instructors from the Iowa Department of Natural Resources, the Natural Resources Conservation Service, and the Marshall County Conservation Board. Together they have helped the students understand their relationship to soil, air, water, sunlight, and all living things. The students walked the trails into forest and prairie and explored the pond. They dug holes into the ground to examine topsoils and subsoils and learned about the many animals and plants living in the soil.
In 1992, Leonard and Mildred Grimes began donating parcels of 160 acres of land to the Iowa Natural Heritage Foundation. A reserve life-estate retains use of most of the land and farm income for as long as either of them lives.
Using Resource Enhancement & Protection funds (REAP), grants, and donations from corporations, civic groups, and individuals, a Conservation Center was built at the GrimesFarm in 2003. The center provides support for environmental education, space for natural history exhibits, a classroom for indoor meetings and activities, and houses the Marshall County Conservation Board administrative offices. Today thousands students in all grade levels enjoy this outdoor classroom. Displays will continue to evolve over the years.
Hiking trails provide access to the forests, wetlands, prairies, and crop fields. Public interpretive programs are scheduled periodically throughout the year. The Linn Creek Recreational Trail from Marshalltown to the GrimesFarm Conservation Area was completed in 2005. This is now another way to access the GrimesFarm and Conservation Center, by bicycle or on foot. Recently the Linn Creek Trail was connected with the Hwy. 330 Trail and the Heart of Iowa Trail at Rhodes. These trail segments are part of the American Discovery Trail
