Igniting diversity in prairies
Much of the remaining prairie in the Midwest Region is fragmented and surrounded by agriculture or threatened by urban sprawl. Along with our counterparts with state agencies, we have been working to replace or restore our prairies for several decades. Unfortunately, tall warm-season grasses are often dominated when trying to emulate a native prairie restoration. Early prairie seed mix contained more grasses like Indian grass, big bluestem and switchgrass than forbs like blazing star, aromatic aster and beardstongue. This is one reason why prairie restorations often result in nothing more than tall grass monocultures. We recently have moved away from seeding that results in monolithic stands of grass to providing an increase of diversity in prairie seed mixes. We currently plant seed mixes with less than five pounds per acre of grass seed and as many forbs as we can afford for that project. However, these plantings, many of which were not supposed to contain any tall grasses, ca...
