As part of a project to characterize the soils in a recently drained basin in southwestern Wisconsin, soil scientists Sam Eldred, Ana Wells and Nick Balster spread the seeds of prairie plants at densities ranging from very high to none. Three years of monitoring has now revealed that despite the altered state of the sediments after 60 years of impoundment, prairie species seeded at the highest densities seem to be holding their own against invasive plants, says Balster. However, the amount of seed this takes 1,000 seeds per roughly 10 square-feet would be prohibitively expensive for most landowners.
Balster is now interested to see if, over time, prairie growth in plots that were seeded at mid-range or even low densities might also prove successful.

What makes a perfect rain garden?
Homeowners hoping to do their part for urban water quality have made rain gardens small garden plots for capturing stormwater one of the fastest-growing features of the home landscape. But as their popularity has risen, so have opinions about the plants they should contain. Some insist that prairie species are needed to penetrate compacted soil and allow stormwater to permeate the ground. Others claim that typical urban plants, such as turfgrasses and shrubs, work just as well.
