Greenbelt Management Plan

Why This Work is Being DoneEnhanced Prairie
The City’s signature park, the Greenbelt, harbors diverse ecosystems, plants and animals. It provides essential “ecosystem services” - purifying water and air and storing flood waters. The Greenbelt helps Clive be a healthy community that people value and enjoy. However, past damaging land use, invasive plants, and erosion detract from that value and enjoyment. Ecological restoration and management will restore the Greenbelt to a healthier condition. This plan was a need identified in the Greenbelt Master Plan that was adopted in 2016. That plan provides the direction and helped shape the implementation of this plan.

Restored Meadow You Should Expect To See
Ecological restoration starts by removing plants like invasive honeysuckle that are most damaging to the ecosystem. Restoration then encourages or installs a variety of native plants. You will see the invasive shrubs and trees being cut and stumps painted with herbicide and a blue dye that prevents resprouting. Some native trees may be removed to thin their dense growth, which suppresses vigorous growth of nut-bearing and other native trees. Damaged trees posing a risk to trail users will be removed, too. In grassy wetlands, the dominating invasive reed canary grass will be sprayed with an herbicide safe for use near water. Lastly, new native trees, shrubs, live plants, and seed will go into the ground. The resulting healthy, diverse, native plant communities will be managed in future decades with haying, spot
spraying, and prescribed burning.

When Will Work be Occurring and by Whom
The City of Clive will hire a qualified, professional ecological contractor in late 2020 to begin carrying out the restoration and management plan. The contractor Enhanced Forestwill prepare sites, remove invasive plants, install native plants, and manage the vegetation for three years. Following this initial effort, the city intend that the long-term management will continue with active efforts for years to come.

What the Benefits Will be
Several beneficial outcomes will result from restoration and management along both the north and south sides of Walnut Creek.
• Forests, prairies and wetlands will have more native plant species blooming from spring to fall.
• Wildlife, including pollinating insects, should increase with greater native plant diversity.
• The park should become more attractive and enjoyable due to the greater plant variety and increased wildlife.
• With dense honeysuckle removed and some tree thinning, people will feel safer and see farther into the park and down the trail.
