Conservation Connection LogoNew Acquisition Brings Exciting Opportunities!
By Harry L. Graves - Executive Director

On January 16, 2002, an eight-month-long effort by the JCCB to acquire the 42-acre former Elmer & Elsie Tomash farm culminated with the purchase of the property from the Iowa Natural Heritage Foundation (INHF). This property is contiguous to and is a natural extension of Kent Park. Its acquisition squares up the park boundaries to Echo Avenue on the west. The chance to make this addition to Kent Park was a once in a lifetime opportunity.

When the Board became aware of the fact that this land was for sale they realized that they would, in all likelihood, never have another opportunity to acquire the critically needed buffer between the park and Echo Avenue. If the Board was unsuccessful in their efforts to buy the property, it would most certainly be acquired for rural residences. If that happened, the Conservation Department's ability to effectively manage Kent Park would be seriously compromised. The onus was on the Board to secure this pivotal property. The JCCB requested and received the assistance of the INHF who made the purchase at public auction last August. The opportunity to acquire the property presented even greater opportunities for the restoration of this new addition to one of Iowa's premier parks. The JCCB staff is very excited about the management plans now being developed.Aerial Photo and Management Plan of New Acquisition

At the time of acquisition, there was a house and two garages on the site. The house and one garage were sold and have now been removed. The newer of the two garages was retained for storage and use as a seed house. Approximately two acres of the former homestead site will be planted to alternate rows of conifers and hardwoods. This cultural method provides almost instant wildlife habitat in the form of the coniferous trees. The faster growing conifers also act as trainers to force the hardwoods to grow up straight and tall. In approximately thirty years, the hardwoods will shade out the conifers and a beautiful mixed hardwood forest will result. (See the map on page 2.) The northern half of the homestead will be utilized as a forest nursery and a prairie plant nursery.


Currently, 39 acres are in row-crop. These crop fields will be rented out for corn and soybean production for several years. During that interim, seed will be harvested from native prairie grasses and forbs from sites at Kent Park. The seed will be used to progressively restore the fields to native vegetation over a two to three year period. Income from the rental of the cropland will inure to the Conservation Trust Account and can be used to purchase additional species of seed not harvested from the Kent Park sites. An additional 40-acre tract within Kent Park, which is contiguous to the 39 acres, will be rented as farmland for a short time in order to restore it to prairie. On that site, Roundup Ready® Soybeans have been planted as a means to kill out the brome grass that is presently growing there. Brome grass provides very marginal wildlife habitat and frequent mowing or spraying is necessary to keep out weeds and other invasive plants. However, the prairie plant community, which is composed of plants that are native to this region, will provide excellent wildlife habitat. This diverse prairie plant community out-competes weeds and brush because of its vigorous growth habit.

There is great wetland development potential in the natural watercourses of the cropfields. The Natural Resources Conservation Service (NRCS) will be assisting in the development of a wetland design this summer.

The ultimate management goal is to take this Highly Erodible Land (HEL) out of row crop production as expeditiously as possible and restore it to native prairie. This will help improve the water quality of Clear Creek and ultimately of the Iowa River. Wildlife habitat, in general, will be greatly enhanced by the reconstruction of prairie and wetlands. In addition, an Ornate Box turtle (Terrapene ornata) population, a state threatened species and Iowa's only terrestrial turtle, is found in Kent Park and vicinity. The restored prairie will provide suitable summer habitat, which should contribute significantly to the maintenance of the naturally occurring box turtle population at Kent Park. The restored prairie will give visitors a microcosmic view of what 80% of the state of Iowa looked like at the time of settlement. It will provide a blaze of color and a veritable visual feast of blooming plants from early spring to hard frost. Watch as the natural beauty returns to this newest addition for all who come to enjoy this spectacular place - Kent Park!
