Fox19: UC finds invasive species taking over Ohio forests
UC study shows how nonnative invasive plants are taking hold in Ohio
Fox19 talked to a University of Cincinnati biologist about a new botanical survey of southwest Ohio that found an alarming variety of nonnative invasive plants.
UC College of Arts and Sciences biology professor Denis Conover surveyed parts of Hamilton County where he found nonnative invasive plants such as English ivy, winter creeper, white mulberry and multiflora rose, among many others.
UC ecology professor E. Lucy Braun conducted a botanical survey of southwest Ohio in 1934.
Conover is replicating exhaustive botanical surveys of the area by UC doctoral graduate and professor E. Lucy Braun in 1934 and Cincinnati botanist Thomas G. Lea in 1834. His study, published this month in the journal Ecological Restoration, helps describe how Cincinnati's plant diversity has changed over the last 200 years.
“One of the most striking differences is the large number of non-native invasive plants that have now invaded the natural areas in the Cincinnati area,” Conover told Fox19.
Conover found dozens of species of invasive plants, but some such as Amur honeysuckle and English ivy are particular problems because they are so ubiquitous in forests and can crowd out other native plants.
Conover said people can help by choosing to plant species that are native to the area in their lawns and gardens.
