Did you know Zionsville has 3 parks with prairie planted that are in progress or established? According to the Nature Conservancy,
grasslands and prairies are among the world’s most imperiled
ecosystems. They are threatened by the spread of invasive species and
the fragmentation and urbanization of grassland habitat. Previously in
Indiana, prairies made up about 15% of the state and were located in
primarily northwest and west central regions.
Prairies are a
complex ecosystem composed of tall grasses and herbaceous plants. Trees
are not a major component of prairies, but some varieties, such as black
oak may be found there. The re-introduction of prairie landscapes helps
reduce the need for labor intensive and high cost maintenance of turf
grasses (ie mowing and fertilization). While Prairies do need a little
extra care to get thickly established, the average cost to maintain is
about $150 per acre, per year - much less expensive than turf grass
Moving or burning is the primary maintenance tool to control weeds for the 1st several years. Typical native plantings need at least 1 burning or mowing during the 1st growing season with all prairie planting mowed at the start of the 2nd growing season. Burning prairies in late fall/winter or early spring is common, but an alternate approach involves more frequent and shorter mowings. By the 3rd season, only spot mowing may be necessary.
Most of the native plant consists of the root system-this is why there is often little evidence of prairie establishment during the 1st few years. With proper management, typical native plants in a prairie will begin to prevail in the 3rd year.
The mulberry fields are in its 4th year and becoming well established. This area contains more basic prairie of grasses and fewer wildflowers. Elm Street Green has been planted with more native species to replace weeds that had overrun the flood plain (Giant Ragweed, Plantains and clover), Once established, Elm Street Green visitors can expect to see asters, cone flowers and various golden rods throughout the landscape. Starkey Park has plantings around the park entrance and the central power line easement.
