Richard Doak wrote a great piece in last Sunday’s Des Moines Register urging readers to “plant the seeds of a more eco-thoughtful Iowa.” Seeding native plants along roadsides has helped the state Department of Transportation save money and labor while user fewer chemicals.
Highway officials cite a long list of other benefits, such as controlling blowing snow, improving air quality, reducing erosion, filtering pollutants and providing wildlife habitat. They’re even said to improve safety by reducing the effects of highway hypnosis, delineating upcoming curves and screening headlight glare.
Doak wants to see much more native landscaping in Iowa:
To set the example, let’s have every school, every courthouse, every park, every hospital, every library set aside at least a patch of space for wild indigo, prairie sage, golden Alexanders, blackeyed Susan, pale-purple coneflower, butterfly milkweed, prairie larkspur, shooting star, compass plant, partridge pea, spiderwort, ironweed, blazing star, smooth blue aster or any of hundreds of other flowering plants that were native to the tallgrass prairie. […]
It’s estimated that up to one-third of residential water use goes to lawn watering, and lawn mowing uses 800 million gallons of gasoline per year, including 17 million gallons spilled while refueling. Some 5 percent of air pollution is attributed to lawn mowers.
Native plants require no fertilizer or herbicide, no watering and only enough mowing to mimic the effects of the occasional wildfires that kept the prairie clean of trees.
Interest in reducing pollution and conserving water and energy should be reason enough to switch to native landscaping.
About ten years ago, our family stopped trying to grow a grassy lawn in our shady yard. After the jump I’ve listed some of the benefits of going native.
