The Carl and Evelyn Wilson Nature Preserve was established in 1990, when their daughter and her husband, Ellen and Eugene Zmolek of Rochester, MN, wanted to memorialize her parents with a gift of two acres to the Town of Traer for an undeveloped natural area. Carl and Evelyn, long time residents, had a strong interest in their natural surroundings. They grew wildflowers in their Traer yard and Carl served as the local weatherman.
The Traer Development Board had recently purchased 27 acres from the Wilson Estate and were making plans to sell home building lots on the subdivision, later named Prairie West. In January, 1990, Jared Bauch contacted Ray and Yvette Berner and invited them to apply for money from a newly appropriated State of Iowa DNR fund, to create a two acre undeveloped wildlife preserve. The State Fund was called REAP (Resource Enhancement and Preservation). Traer had to compete with many other towns its size to win the funds. In April, when it was announced that Traer was a successful recipient, Ray and Yvette were ready to go with a prairie restoration, a small butterfly garden and a small woodland of native trees.
The butterfly garden was planted with 400 plants on April 21, 1990, and the seeding of the prairie restoration and the tree planting were done in May and June that year. A disaster struck on June 6 when heavy rain-washed out about 3/4 of the new prairie seeding a few days after planting. The washed out section was reseeded in 1991. There are currently 10 native grasses and 75 native forbs (flowers) in the Nature Preserve.
The prairie reconstruction, in 2003 is in its 14th growing season. A reconstruction needs up to 10 years before it reaches satisfactory saturation of prairie plants. For example, compass plants and leadplants do not bloom until the 4th or 5th year.
