Featured: Cleveland Metroparks The Cleveland Metroparks is a system of nature preserves in Greater Cleveland. The preserves, which encircle the city of Cleveland, Ohio, generally follow the rivers that flow through the region to Lake Erie. Referred to affectionately as the "Emerald Necklace", the network of 16 reservations across 22,000 acres includes hundreds of miles of walking, bicycle, and horse trails, parks, picnic areas, five nature education centers, seven golf courses, and abundant fishing holes.

Hybrid vigor is not a phenomenon restricted to agriculture. It is a property of wild populations as well. Numerous ecological studies are focused on the amount of genetic diversity in wild populations. Small populations with low genetic diversity suffer from inbreeding, and thus poor physical qualities, compared to large populations with high genetic diversity. So if that’s the case, why don’t we let our fields be continuously open-pollinated, like our ancestors did with landraces? The reason is that we still benefit enormously from plants that consistently fulfill specific criteria essential for efficient farming, things like particular flowering time, maturity time, photoperiod sensitivity, stress tolerance, etc. Thus there is always a balancing act, and a lot of work goes into identifying plant lines that will satisfy all criteria, whether you’re creating inbreds or hybrids.
