On Wednesday, Iowa Learning Farms hosted a webinar about the benefits of reducing mowed land area across rural Iowa. Adam Janke, Assistant Professor and Extension Wildlife Specialist, discussed a project which considered the economic, ecological and aesthetic impacts of managing idle spaces differently.
Three different management scenarios were compared: traditional turfgrass, the “lazy lawnmower” and pollinator habitat establishment. In the traditional turfgrass management scenario, the space is planted to a monoculture and mowed weekly. In the “lazy lawnmower” scenario, mowing is done less frequently, about once every three weeks. Finally, in the pollinator habitat scenario, pollinator habitat is established in the area and managed to create a diverse source of nectar resources for pollinators.
The economic analysis of the three different management scenarios showed that both the “lazy lawnmower” and establishing pollinator habitat saved landowners money (and time, since their time was also valued in the analysis). Out of the three, the establishment of pollinator habitat had the lowest per acre cost per year. Janke also showed that, ecologically, there are no benefits to increased mowing.
Why maintain turfgrass when is is expensive and lacks environmental benefits? Literature on the subject acknowledges that this behavior might not be rational, but that it is part of our cultural norms. Worrying about what the neighbor might think of how you manage your land plays a big role in behavior. In order to increase adoption of different management scenarios for idle land, we need innovators who are trying out the practices and showing people that they can work.
Janke shared examples of three places that have adopted pollinator habitat instead of traditional turfgrass in idle areas. The image on the left shows a farmer who is a champion of monarch conservation who converted an idle area on his farm where to pollinator habitat. The middle image is from a farm that was part of a project with the Iowa Monarch Conservation Consortium who partnered with pork producers to convert idle areas outside of livestock barns. Check out this video to learn more about this project. The image on the right shows pollinator habitat on idle land at Workiva in Ames, shortly after it was burned this spring as part of the management of the area.
